I am installing a sub and amp in my car this weekend. The sub is rated for 1060 peak watts and a 1100 peak watt amp. oncei have it all set up how should i put the settings since i really dont know what they mean.

it has:

level 5v - 0.2v
bass eq 0db - 12db
hpf 60hz - 1.2khz
lpf 30hz - 250hz

x-over full, lpf, hpf,

mode mono - stero ( i am putting it in mono cause its just 1 sub)

any input would be greatly appreciated

ok for proper peaking, you must also list your subwoofer specs,
what kind of enclosure, sealed?,ported, bandpass,free air panel what are you using?
also the full specs are needed if your running a single sub in the car you need to know what the impediance is rated at also the ability for what you can run it to stable,
is your amp able to run impediance at a lower rate?
is your amp too powerful for your subwoofer?
what kind of inputs are you running? whats the attenuation?
you need to have the least amount of footage from source to amplifier, also proper grounding thats no problem, keep it away from power sources as you can eminate noise in the line if not shielded for the inputs that is...

peaking a system can be well involved or you can just slap it in
is it quality or just a easy slap in?

get in touch if you need help...

BTW HPF is high pass frequency
LPF is low pass frequency
get me spec ill give you an idea where you need to cut frequencies at
and the specs need to have frequency ranges
handling power specs
and the impediance of the subwoofer
also if you know the actual q mass and box spec that will help too...

Correct if I am wrong, but isn't HPF mean High Pass Filter and LPF Low Pass Filter?

Zaar

you are not incorrect, but what are you filtering... frequency right?
its the control to cut the frequency from the amplifier to the output channels...

sub specs is:

power handling rms 275w
power handling peak 1100w
frequency response 25hz-400hz
impedance 4 ohms


it is a sealed box


specs on amp say:

4-ohms 225 x2
mono bridge at 4 ohms 1100x1
frequency response-3db 30hz-1.2khz
input impedance 47kq

well your amp is awfully strong for your sub your normally want to keep your input range to the sub at the rms area anything more then that your overthrowing the sub.
its your nominal range. so if you have a dual voice coil? you can bridge it but my advice is to utilize both channels is it a 4 channel amp? or 2 thats a crazy set up whats the brand and model of your equipment?
also if you want to bridge the amp keep the level down so you dont eff up your sub
start from zero and work up. cut the high frequency in between and the low frequency in between should be a good working zone as long as you dont cut out the frequency of the sub in its operating area anything higher remove kinda get that right. its kind of like fitting a circle in a box if its not round it wont fit you need to set your settings so the shape, curve will fit so adjust the amp to accomodate the sub specs, your amp makes the sub sound proper, so it may need fine tuning after the fact but the beginning steps like what i said should give you the foundation to make adjustments. Do Not Put your output level too high like i said slowly adjust the level up to your liking, so start from zero and move up...

do you mean the level or the bass eq?

what wierd is on the level dial the setting all the way to the left says 5v but to the right it says 0.2v? wierd how it goes from high to low when all the other settings go low to high. i dont belive it has a duel voice coil looks like a regular sub


this is the sub: http://www.crutchfield.com/ISEO-rmsb...ity-1060w.html

and this is the amp:

http://www.sonicelectronix.com/item_...h-P1100.2.html


so with the amp looks like the peak bridges is 1100 but the rms is 550. the specs say the sub rms is 100-275. so am i safe to assume i wont blow the sub because both peaks are 1100. and either the level or the bass eq should probably be best around 25% or a quarter turn?

the level is just confusing though because what i explained above

one thing you need to remember is that peak power is what the amp will put out for at least one second. i look at rms power levels. bridge it to 4ohms. turn the gain down. then turn up the rest of the stereo to where you NORMALLY LISTEN TO IT. then turn up the gain till it sounds good. then turn the stereo up till it starts to blurr sound. then turn it down some. adjust the gain on the amp till the sub starts fluttering and then down some. that should get you close. i usually keep my subs in the 20 to 200 range on hertz. leave the eq db alone for now. and put it on low pass.
