[QUOTE="jmcs23, post: 8094868, member: 612071"] Hello, Here's what I have installed in my 2003 Nissan Altima: Lanzar Vibe 435 amp (4 channel, 4 x 200W RMS at 4 ohms) I have the subs bridged on the amp. 2 Sony XS-L151P5 15" subs (400W RMS each) JVC KDR730BT headunit I'm using a cheap/off brand 4gauge power wire, ground wire, RCA from an auto parts store. First off I know my equipment is old, but I've never had any problems with it and it sounded just fine in my old car (2000 Civic) the only difference was I used Kicker or Kenwood (can't really remember) power, ground, and RCA cables. When I was using everything in my Civic I actually had the gain and bass boost turned up all the way and it sounded fine with no problems. In my current car if I have the gain and bass boost turned up all the way (like before) it just doesn't sound right and if I turn the volume up on the HU too much the amp will go into protection mode which it never did before unless I ran the amp for several hours and it started to get too hot. I tried adjusting the gain and bass boost down and the amp doesn't go into protection mode but the bass *****. I also tried many different configuration settings on my HU too. So I'm trying to figure out what happened. Why does everything sound bad compared to when I had everything installed in my old car? Could it be the cheap power, ground, and RCA cables that I'm using now? Any input is appreciated! Thank you! [/QUOTE]
