Hello I need some advice. I am not too familiar with car audio stuff. I have a 6 channel JL Amp. I have from my front and back speakers hooked up to teh 1st 4 channels. I had channels 5 and 6 bridged into 1 jl audio 10" sub. I believe my sub blew so I had a box with 2 MTX 4500 subs in it. My question is should I keep channels 5 and 6 bridged gong into the 2 subs or do I use 1 channel for each sub or just use 1 sub like I have been doing. Any advice is appreciated.
