Ok so just got a new jl audio 500/1 amp and two c4competition subs( i know the subs arnt to good but i got them cheap and in the next month am going to get some better ones) but my problem is this
I connect my power from the battery ran it through the firewall to the amp. Then ran the ground from the amp to the bolt on the passanger seat. then ran the remote from the amp to the HU, had to get a ttap to do that but got it working. Then when i run the rca cables from the amp to the sub inputs on my pioneer DEH-P3900MP nothing comes out. But get this if i have one of the rca inputs in the input holes on the hu then i touch the side of the other rca cable to the HU input not in the hole just on the outside the subs come on everything works fine. I havnt had time to get new rca's im really really hoping these are the issue not the HU.
any suggestions? anyone think just redoing the ends on the rca cable would fix the issue? or is this a HU issue?
