Kinser

I got it bolted down under the rear seats on the floor pan, sanded the paint off in the area. clean as hell! I don't think i can fin a cleaner spot in the rear of the car.

No i haven't.. i thought the ground should be kept as short as possible.

Hey Guy, name is David new to the SMD forum! Little Intro on my system before i start... Sub, TC Sounds 12" DVC TC2000 in a 74L ported box tuned to 26Hz IIRC running on a Mac Audio Fearless 1000 Monoblock. HU, Pioneer DEH-P5950, JBL Components running on a crap 4ch amp. stock electrical system. story goes like this.. about a year i had both amps running straight off my PSP, had no HU back then. one day the RCA wire coming from the Mac Audio just melted down, replaced it and worked fine. while after that hooked up a friends HU, the idiot uped the volume before i had a chance to lower the gain and the internal ground wire from the PCB to the RCA jacks burned out. replaced that and the amp worked fine. got the Pioneer HU a couple of months ago. the pico fuse went POP so i did the ghetto fix grounding the RCA's to the HU body, worked fine after that. this morning on my way to work, playing Late Night Tip, the 4ch amp touched the mono block, head a thump from the sub, next thing the sub RCA's wire started melting and burning about a foot away from the HU. switched it all off pulled out the fuses and carried on to work. i suspect that the mono block is trying to ground itself through the RCA jack on the amp. cant understand why though, got a 2 gauge healthy ground wire on a nice smooth spot on the floor-pan. dunno what to do anymore, ran out of ideas! appreciate any help Thanks, David
