[QUOTE="KaMiKaZi_t0M, post: 4110995, member: 583328"] Alrightm well I'm thouroughly confused. Today I tried to switch my subs over to my 800w amp (crunch audio) becuase the stock sub amp (visonik, yeah i kno it sucks but I'm poor) one of the channel's blew. So I pulled out my HU, and swapped the RCA's. After that, I powered the HU on and heard loud thumping noises comeing from everything powered by an amp. I quickly changed the rca's back to the other setting, still loud, pulsating feedback. I only get the sound through the amp'ed speakers, not through my dash speakers that get power on my HU. Thing's I've tried: Direct ground to the battery. No help, exact same noises. I don't understand, I have power direct from the battery, and a ground directly to the battery. Could this be a problem with my Headunit? It's a Pioneer DEH-P6800MP. Please, help, I'm sick of listening to my dash speakers, I want my thump back =[ Many thanks, Tom [/QUOTE]
