[QUOTE="MrNutter, post: 7418936, member: 635111"] Hello everyone, this is my first post & question, so please be gentle. Forgive me for the novel I'm about to write but if you can wade through it & help me out I would very much appreciate it. My old amp (sony xplode 600w 4ch) died the other day so I used that as an excuse to replace the amp & upgrade a couple of other components. I got another 600w 4ch Xplod as I was actually pretty happy with the last one & it lasted me for years. I also got a Pioneer 1200w sub in a ported box & a pair of 6.5" 280w Clarion component speakers. I put the new Clarions in my front doors & installed the wiring harness that came with them. I took the old Sony component speakers & thier harness & put them in the parcel shelf wired to my Sony 6x9's. None of the speakers on the back shelf are wired into the amp, only to the HU. The new Sub went into the boot using the existing wiring & the amp got bolted to the back of the sub box where the old one was & also using the old wiring (basically identical amps). The fronts use two of the amps channels & the sub is bridged over the remaining two, just like it used to be & as is recommended in the amp instructions. I crawled into the back to adjust my gains & managed to set the fronts with no problem. As soon as I turned the gain knob for the sub though, my front speakers fell silent but the sub kept working. I checked the amp fuses & they are fine. I switched the RCA leads over & I had no sub & no fronts. This isn't looking good for the HU. Leaving the RCA's as they were I wired the front speakers to the subs side of the amp & the sub to the fronts side of the sub. Now I had fronts but no sub, so both sets of RCA's appeared to be working because both sets have either had the sub working or the fronts working. I'm thinking the problem is channel 1/2 on the amp. I switch the RCA leads back to thier original positions & leave the speakers as they are, now I've got a sub & no fronts again, so the sub is now working through channel 1/2. Now I'm really confused.
