[QUOTE="ryanfreeland, post: 6943478, member: 623099"] Okay, I want to run this setup by you guys to make sure it makes sense before I buy all this stuff. Right now I have a set of Polk DB6501 components (100RMS/300 peak) in the front and a set of Alpine Type-S 6x9's (85RMS/260 peak) in the back. Everything is being run off the head unit right now, but the next big upgrade is powering these speakers by a 4-channel amp, specifically the Crescendo 1000C4. My head unit is a Panasonic CQ-C7301U. When I redid the front speakers, I ran new 20 gauge wire through the doors to the head unit. Here's the theoretical new setup: Power: 4AWG from battery down the passenger side to amp (in the trunk) and 4AWG ground wire. Signal: RCA cables from HU down through the center console into the trunk. Now I have 2 major questions: 1. The Crescendo puts out 125w @ 4ohms per channel, and I know its better to overpower speakers than it is to under power them. (the fronts are seriously underpowered now). Right now the back speakers are a lot louder.. will I be able to adjust the gain controls on the amp to equalize the volume difference? 2. What gauge speaker wire should I run to the speakers?
