[QUOTE="shaggy112, post: 480, member: 540952"] i just finished installing some new stuff. it sounds nothing like i would expect it to. My car is a 94 Merc Cougar. I have spent a lot of money on all of this. I am sick of my car sounding like crap. Please give any opinions that you can. I just want to get to the bottom of this and fix it. Here are the problems in order of importance: 1- Bass When I listen with low volume, it sounds ok. When I turn it up past 1/4th on the HU, the bass distorts. It isn't even as loud as I would expect. Would this mean that my amp is clipping? I have had a previous system that I got rid of that did the same thing(2polk ex10's, RF Power 400A4). I have played with the gain and xover freq a lot, and haven't been able to produce good results. 2-Highs They are very bright, and almost hurt at moderate volumes. Again, does this mean amp is clipping? I know that the JVC is not a great amp, but I ran out of money, and I would expect it to be decent. Again, when I had my RF Power 400a4 on the same polk speaks, it did the exact same thing. 3-Mids These are decent, but are lacking. Not a lot of punch. I am assuming that is due to the fact that the speaks are 5x7. I am not to concerned with this one right now. Here is what i have: HU: Blau Meuchen -- (2 stereo pre-outs, 1 mono-out) Front-Speaks: Polk EX572a (5x7" full-range....handle 60rms) Rear-speaks: Polk EX572a (5x7" full-range....handle 60rms) Front-Amp: JVC KS-AX4700 (100rms x 2) Rear-Amp: HeadUnit Sub: Alpine SWR1240D (handles 300rms, 4ohm vc's) SubAmp: JBL BP1200 (reason for big amp: plan on second sub) Box: Raptor 1.0cuft Sealed Wedge Cap: 1 Farad LA Bolt Off brand Dynamat on doors and lined in trunk. Here is how I am wiring: Power: Audiopipe 4guage ~16ft --> Cap -> Dblock (4guage IN 8guage OUT) Ground: Dblock (4g IN 8g OUT) -> attached to top part of trunk...not the lid, but behind that, close to third brake light. paint scraped off. AMP Wire: 8guage esoteric, JBL has about 5" from dblock, then 4" from cap. JVC has about 2' 8guage esoteric from dblock. Same with ground, going to the second dblock. RCA's: ~16' Streetwires (forget model, cost about $20 per) Speaker Wire: Polks--14guage RF wire, Sub--10guage RF wire The sub is wired in parallel, presenting a 1-ohm load to the JBL. The gain on the JBL is set ~25%-33%, x-over at ~100hz. The Polks are going directly to the 2-channels of the JVC presenting 4ohms. Gain set at about 1/2. Xover set to HP...no freq settings. I have a factory alt, and a diehard gold battery. THANK YOU! [/QUOTE]
