Possibly the stupidest question ever?
My previous thread I mentoned finding a small Alpine AMP, #3505.
I finally dug up some interesting info on it. This model actually came on some high end cars from the factory but I'm sure in different trim and it's 25 watts per channel which is probably good enough for my use, to drive my 4x6's. Now my two low out's are taken one for the sub and one for the 6x9's so my choice would be get a splitter or run off the high inputs.
Heres the stupid question. Since my head unit is "20/25 watts per channel" if I run to the high input to this AMP will it add anything or will it reduce the signal or what??
I understand the wattage from the head unit is just rated at the 25w maximum output so I should be ahead of the game by running this tiny amp. What do you think?

well you could wire it in temporarily to see what it is like, but I really dont see you making that big of a differance with it. Most modern HU's have decent amps built in, and seeing as how old that amp is.... I just dont see it making a big differance.
That said, cool find!

I think you should still see an improvement. Not in how 'loud' it gets, but how 'full' the sound is. Give it a good before and after listen (just on the front) and I think you get an improvement in the highs and lows, more with the lows, but you're NOT going to hear that with those speakers so concentrate on the highs. DON'T use the high inputs, get a splitter.

Ok I'm here at the shop or as I like to call it my birds home.
My head unit is a Pioneer 50x4. So thats 12.5W per channel right? So it should show an improvment by using this amp.
What do you guys think of the passive dividing boxes in the pic? Should I use those peices too since the 4x6's are just for highs?

Most headunits can output around 20-25 watts per channel but they do so at 10% THD, which is horrible. Most amps make their rated power at something like .0x% THX. You might not be able to get louder but it will defiantly sound better.
I agree with NEEDAZ - get a splitter.

If u had another set of RCA outputs to use, it would be marginal as to whether or not it would be worth hooking up the amp to gain such a small amount of power. But since u don't, it's definitely not worth it. Using the high-level inputs will more than enough distortion to obliterate any small improvement u might have seen, and using Y-splitters on the RCAs for the 6x9s will weaken the low-level signal and eliminate your ability to fade from front to rear. Overall, any gain u might notice will be very minimal, and there's a good chance it will actually sound worse. Not worth the hassle.

A typical modern aftermarket HU will put out about 18-20WRMS when driven full-range at low THD. Given that this Alpine amp was manufactured to OEM standards rather than typical aftermarket standards, I"m sure it won't be much better than your HU.
using Y-splitters on the RCAs for the 6x9s will weaken the low-level signal
This is a lot of discussion for such a small amp.

what if the headunit was similar to the new Pioneers that output 30wrms?
I would just get a much better amp on the cheap...

please go to a pawn shop and get a decent 4ch for like $50...
or he could get DVC speakers and wire up the 4ch amp to power up a single pair... then he'd have ample power
