ok i know alot of ppl here won't agree w/ any of the 3 but i need opinions from ppl who have them, use them, or have heard them, compared to each toher or something else.

they are all reasonably priced which alot dont like and say they are junk hey poor boys got poor ways n better then stock.

im lookin for a good one to push a set of pioneer 12s
the 400 or 450 wat ones maybe 12s or 10s

i can get them for reasonable prices like around 100
i have sen jensen amps before and they do work and sound good work well.
the 2 ive seen were hooked to jls which are awesome anyways but the jensens done the job of pushing them nice.
and i have heard an old set of pioneers on a jensen which sounded awesome as well.
so anyone had any experence w/ spl's or power acuostic?
both jensen and power acoustic are available from summit and spl is available locally to me.
which do you guys think is best?

im fuzy on the ohms thing.
i dont understand it i know most car speakers 4 ohms and all i know is hook the hot to hot and negatives to negatives
hot meaning positive thats what i call it.
and +2+s on the speakers and amps and -2-s thats all i knwo so how would i get 2 ohms?
reason i ask heres the specs on the spl's

125 watts RMS x 2 into 2 ohms
300 watts RMS and 520 watts peak power in bridged mode
Selectable crossover settings for full-range, high pass (150 to 1500 Hz) or low pass (40 to 120 Hz)
Bass boost of 18 dB at 40 Hz
10 Hz to 30 Khz frequency response
Total harmonic distortion of less than 0.02%
Signal-to-noise ratio of 97 dB
Die-cast aluminium heat sink
3-way protection with system distress indicator
Tri-mode capability lets you power 2 speakers and a subwoofer
Gold-plated line level inputs (from preamp outputs)
High level inputs (from speaker outputs)
Line level output
4-gauge power and ground connections
11.25"L x 11.25"W x 2.25"H


the jensen amp says its 2 channel 340 watt
170 watt x2rms

or a 460 2 channel 230x2rms

and power acoustik
2 channel 520 watts
125x2rms

they also i just noticed a pioneer amp only says 200 watts tho dunno the rms wished it had that
anyone know what it might have rms its in summit racing book
item # pnr-gm-x362 ?

 

Even poor boys have better options. Look at the JBL stuff in your price range and don't get hung up on the fact that the JBL stuff is "rated" at less power than the other garbage. It'll play as loud or louder dollar for dollar, and it'll be more reliable and better sounding.

 

never seen any jbl for under a 100 or right at it
no place locally either.

had thought bought it tho.
ive read alot of *** things about it.
and i trust what u say because almost every board on car audio ive checked here yuve posted.
u work installing stereos at audio place or something?
from yur posts sounds like u do or have.
thanks for the help

 

hmm moderator too thats cool i didnt notice that.

would it be aight to send u a pm or go ahead n post on this off topic about thoose line out rca converters?
u know were yur hu doesnt have low output rcas for the amp and ive heard n seen another post on hookin amps to high output or using thoose and appeared that best option was those.

so let me know if yud rather pm or just want answer here and il ask u the ?
because i dont really need everyones opinions i trust yurs.

 

I'd try to help but... I can't really make sense out of the post.

it luks knda like u hav e a broke keybord er sumptin ebcause ur postes r like tihs

 

That's because nothing under $100 is worth buying no matter how broke you are.

 

I used to run the Walmart Jensen sub and amp combo in my tempo. It was ok for a starter sub and amp combo. The sub was a 575watt 125rms sub and the am was a 300watt jensen amp. It made enough noise to wake up the neighboors however was no where near the performance of my current Kenwood Tornado 700watt sub and 350watt amp.

 

Check out www.ikesound.com - they sell JBL amps on there for CHEAP. They're reliable, I know a bunch of people running them for awhile now and never have had any problems.

The problem with jensen and other cheap amps is you'll find they're horribly over-rated and under-power. What I mean is, they'll say they run 1000w - and in reality, they push no where NEAR that number, it's usually around like 300w. Crazy huh?? JBL rates their wattage good.

Definatly check 'em out!!

 

hey guys thanks for all yur help

but...
a friend of mine stopped by today and made me great deal 2 brand new ozzy auto subs i think he called them and a kenwood 600 watt amp for 200 bucks
and he built the custom box hisself.
i couldn't refuse that deal.
man i hooked em up they sound awesome.
i played em lil too much tho i got a huge headache and they are great on low bass which is what i set them to as for mids of high bass not great.
kinda disort it sounds liek but he said they never been played so they need broke in.
il get up some pics on here soon.
man they shook my whole car something bad and theyd vibrate u to death inside bout like my friends 2 jls in the trunk of his tempo.

 

OK i know i'll get flamed for it but hear it goes...I listened to Jim and a few others on here and bought a 10inch elemental designs e10kx.22 sub and a rockford fosgate 301s...nothing huge but i hope the quality gives me better sound and performance (waiting to install cause ikesound hasn't got me my amp) grand total for these two items plus el cheapo amp kit at walmart bought 350 bucks! But i think you should hold out for better stuff. If you want to go cheap but ok sound...my friend just bought the DUAL brand sub box with 2 10 inch subs in a ported box and a 460 watt DUAL brand amp from best buy...truthfully to a cheap highschooler it doesn't sound bad, but its probably becuase i've yet to be around good systems. However for boomy bass, if thats what you like, it does the job! BTW his system cost him 275 bucks...if you save more and spend more on equipment you'll get better stuff. Just food for thought.

Sorry for the post didn't get my reply in soon enough...lol

 

no prob man i appreciate u lookin and replying anyways.

mine now could use somewhat to be desirerred on the high pitch and mid bass whatever u want to call it hard to explain.

but my buddy told me leave my amp down to the low thing because the high or whatever would try make music n sounds n all come out n sound ****ty said way it is now all low bass and it is and awesome too but liek i said not so great on the top end higher types.
but i have yet to fully play round w/ them.

im still confused on what he caled them auzie or ozzie autos or something.

i was goin to post up a pic but my pc bein a bitch again so ill reboot and try again guys.

 

man this pc pisses me off sorry guys have get pic later im beat goin to go lay down ive ben at it for round 12 hrs or more today so ill try again later my pc and digital cam wont work w/ me.

i took a pic turned out great posted as attachment in here n screwed up was so blurry couldnt make it out.

they have purple or blue circle on the cone in middly and lil grey/white zig zag lightning bolt like goin from left to right coming out of the circle and say vector on them over top the zig zag.

 

Hey benoit454, I know your friend told you to leave the "amp down low", and I think he's talkin' about the gains, but you maybe able to get more outta your amp and get a lil' more bass if you're interested. Setting them is very easy if you know how to do it.

First, put your hu up to 75-80% max volume, then it will be running at the top of RMS power.
Make sure you eq settings are all at 0 (bass, mid-bass, treble).
Next, go back to your amp and find the ****-like thing. This is your amp's gain.
First thing you should know is this is NOT a volume button. The purpose of this is to match the volts of your preouts with the voltage that the amp is running at.
Slowly turn the **** until you start to hear distortion coming out of your subs, then turn it back about 1/2 rotation.

I'm appoligize if you already knew this, but if you did not mess with the gains at all, they're mostlikely set for your friend's hu and not yours. Which, depending on how your preouts compare with his, might be underrated or overrated. If they ARE overrated, you can cause the amp to clip, which will do perminant damage to your subs - mostly in the voicecoil. If the voicecoil melts, your subs are dead.

Hope this helps! And congrats on your purchase, s'long as you like 'em that's all that matters!!

 

i think i kno what u are talkin about its a dial and says max n that sorta thing if im not mistaking its set to max or something.

never ajusted em before and in our s10 they both set to max i think.
but he was tellin me about a switch on the back for high pass low pass sorta deal to were low is only lows,
and high or full pass or something is like for all music n soud to come fomr subs n he said would sound like ****.

my subs kick *** on low end but for mid to higher range mainyl distortion.
i can get u more specs later for my hu and amp all i can say now (not at home)
jvc 160 watt 17 rms by 4 hu and kenwood 600 watt amp.
can get numbers later tho.
i know max vol on hu is 50 i think its goes all way to zero as well tho for some reaosn i was thinkin 30 or 20 to 50 but thats seems wrong the vol number should go fomr zero to 50

so im guessin mid well 75 80 percent would be right around 35 or 40 thats were seemed to sound best anyways that day.

i only had them test wired n junk that day very rigged setup like speaker wire both sides hot n cold twisted together for grounds and hots and acc wired straight hot and ht wire direct fomr battery and i have no preamps rcas so its high input wired and i asked my friend bout it he said well u can get line converters but were the amps capable of both itll be same either way.
im not sure on that but him n another friend worked in audio shop installing professionally for few yrs and done it on there own for many years before and after that.

so ill get back to u on adjusting it or ill take it to him n let him adjust it all right.

he had the amp in his wifes car which got wrecked and she had liek a 300 dollar hu in it and some subs dunno what kind but tsubs he sold me he said were brand new.

i dont want to permanently damage my subs by the sudden surge or anythgin liek u were talkin about by over powering them or whatever which i think is what he was sayin when he said....
now if u like crank it full out for like really long periods then yea it may pop them subs n over power em then pop em i mean.

so im thinkin ok cool no biggie my bass is like +4 in hu and treble around -2 to 0 and fad to rear at around 4 or 3

 

Well, like I said, it really isn't good to have the gains up the whole way on the amp, because you will end up clipping the subs and you can damage them that way. It just depends on how powerful the amp is how much damage will be had when they clip.

If your subs sound distorted when you have it up louder, I would definatly mess around with the gains and reset them, because it sounds like they're set to high. Of course, w/o hearing it, I can't guarentee that's the problem. But no distortion should be present.

Put your volume to 35-37 to set the gains. If you have a CD with bass test tones, that might also help. Or something with steady bass. It's not best to set the gains with rock music. After you set them, stick something with all levels in (treble, mid-bass & bass) make sure it sounds good then.

Good luck!!

 

aight man i gtocha i was plannin on playin w/ the full pass low pass switch and stuff anyways now ill fart round w/ gain as well and yea i got some bass cds.

also one other point he told me not to hook my subs bridged or monod because it wont run 1 ohm or 2 ohm stable .

which i didnt im thinkin pretty sure correct me if im wrogn bridged/monoed is both hots goin to say left hot and both negatives goin to right negative right?

 

also it will lose some bass n power by lowering the gain wont it?

and clippin em how can u tell if u have or when u do clip em?

 

unless you buy used, my sub cost me $60 infinity 1220W, and i'm running all my speakers, 4x6s, 6x9s, and the 12" off an mtx blue thunder pro 4 channel amp all for about $200Canadian so about $150US and i guarentee ya it'll sound better than a jensen system

 

I dont care what anyone says but spl\power acoustiks are the best over rated amps. If anyone else says another overated amp is better i have to hear it to belive it.

 

1 - Possibly. But think about it this way. You've already said yourself that your bass gets distorted. I personal would rather have less boomy-bass w/ clear sound, then boomy-bass that's all distorted.

Also, how do you have you subs installed? (Like, the box positioned)

2 - Sometimes you can tell they're clipping thru distortion, a lot of time though, you don't know until it's too late.

Say your amp is normally sending 100 w to your subs. When the amp clips, it sends 5-10x the usual wattage. Which obviously, the sub was not built to take. When you do this, the extra wattage can heat up the voice coil and eventually melt it. If this melts, you will have no sound coming from your subs. To repair the voice coil is more than it's worth. Sometimes it clips for a milisec, and sometiems it's longer than that. Regardless, depending on how loud you have your subs up when/if they clip, it can do more damage.

And you asked about bridging, you had it right. Your amp is probably stable at 4ohms. If you would bridge them, they would be running at 2ohms probably. If you did accidentally wire them the wrong way, it would eventually just turn the amp in to protection mode, shutting it off because it got too hot.

Hope this helps!!

 

yea i thought so...

as for bass the low end i know hard to explain but low bass real deep doesnt ditort no matter how loud the vol bass turned up trebble any of it no matter what or how loud the low bass doesnt have any probs.

its the higher end mid high bass things that just no thump or bass to them just mainly distort.

which i figured the way he said amp was set only for low bass that id need some components to hanld it to comeplte the whole system and delivery mid/highs

cuz like i said i got no complants on low its awesome and deep and extremely clear sounds as good as jls.

but on certain songs on the tones or forms of bass the higher notes not the deep low low bass it doesnt sound good at all

i asume its were its set to run only lows tho ill check into it its hard to explain on the net but thansk for the help.

ill check w/ 2 or 3 of my stereo fanactic buddies n have em tune it better for me.

 

get the Volfenhags, they are really good
and on top of that they are pretty cheap

 

I heard volfen hag subs are good but there amps are kinda weak

 

Why, may I ask would you want over rated amplifiers?

Maybe you ment under rated?

 

Just becuase its over rated dosent mean it dosent produce sound.
Im just saying i rather have a spl or a poweer then one of these

 

Hey, didn't mean to come off harsh or anything.

I know that an overrated amp will produce sound as well. Thats kind of a silly thing to point out.

I was only trying to indicate to you that an underrated amp will be a better choice if you have the option to choose.

If, for some reason you are specifically looking for overrated amps, then by all means go for it.

The brands you mentioned before are quite reputable for quality in their target market.

I hope you manage to get the best amp for your particular needs.



Edit: Pyle amp?? LOL *shudder* Looks like a hybrid between a sony and a pyramid.

 

Isn't that like saying "she's the best two dollar ho' on the block"?

I've bought cheap stuff, but it was because I wanted cheap stuff. My '83 C10 has a Roadgear CD player running two White Westinghouse 4.5" speakers mounted on the kick panels in those cheap plastic angled speaker housings, and a Roadgear amp bridged to a Pyramid 8" sub I bought **-Two for $20-** at the local Swap-O-Rama flee market. The whole system cost me ~$120.

Does it sound good? HELL NO!!!

Do I care? HELL NO!!!

Am I happy with it?? HELL YEA!!!

IMHO, the best "cost effective" stereo stuff on the market is one of three companies. Pioneer, Kenwood, and Blaupunkt (I never spell it right), although Kenwood speakers suck, but their subs are OK.
