Sounds like CRAP!

Ok ive recently put in a soundstorm labs 1600w amp, 2 audiobahn 12s, and a clarion head unit 50X4. I used a scoshe wiring harness from walmart that was made for ford cars with premium sound and this included the mustangs with mach 460. I wired it up and too my knowledge after checking, rechecking and rerechecking it is correct. The problem is im running one sub and getting quite a bit of bass(I think i need a capacitor for my amp to run the other) because the amp is rated at 300wX2rms at 4 ohm. Speakers are also 4 ohm. Also the biggest problem is that everytime the volume gets to around 19 or 20 the speakers start scratching and just sounding like crap. It sounds fine at lower levels but when you go to get a little loud with the windows down it just starts scratching. What can i do and how much is it going to cost? I need to get this fixed. If you need anymore info post up and ill get back as soon as possible.

Subs? or doors? The factory 460 is still in there. The left side amp is disconnected so the factory subs arent going. Other than that its fine right down to the factory plugs. The subs are ran from the amp to the spreaker with 14 or 18 ga. cant remember which. I have the one sub bridged right now on the amp and it hits pretty nice.

Don't take this wrong but I can not figure out what you have going on from your first post in this thread. I'm happy to look at it.

the problem is that the amp is tunned wrong. if you have 2 4 ohm subs you can also wire them up in parallel or series. this can effect what ohm load you are sending to the subs. the reason that you have destortion at high levels is most likely you have the gain turned up to high. Whenyou wire the subs up do not bridge them together.

The truth which makes men free is for the most part the truth which women prefer not to hear

stew, you are misinformed, you do want to bridge your subwoofers together at the amp, making sure that you wire them to > the total impedance that the amplifier can handle.

No the sub and amp are not the problem. The problem is i think i am overloading the stock speakers. Its the voices that are the problem. I only have one of my subs hooked up and it is just fine. Its the stock mach 460 that is the problem. I think im just overloading it.

I'm still unclear how exactly you have it setup. But if you're feeding the mach460 amps signal from your new HU, the signal may be too strong causing distortion. If it's not playing very loud, but it's still distorting, it's signal related most likely.

How can i change the signal because thats what i am doing. I bought a plug and play harness so its plugged into the old and wired to the new headunit. There is no gain control or anything on the harness or in line.

The problem is in your head unit and the scosche wiring harness. If you have an aftermarket headunit, the signal to the amps is messed up. the signal going to you stock amp is way higher than the Stock unit at higher levels. put the stocker back in or buy a signal converter so that you can adjust the level from the aftermarket radio to the stock amp.

Hawk

Best buy, Hawk, circuit city. tell them whats going on and they will know what you need right away. Talk to an install guy. I would recommend Hawk electronics.

20bucks

$20 dollars or so. Not hard to wire in as long as you are good with wiring.
