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.
