OK I am about to have 2 12" L7s on 2000 RMS sooo I think Im going to need to upgrade my frontstage some. I have a 200 RMS 4 Ch JBL amp that I want to use. I MAY use rear fill, right now rear speakers are out of the deck so more bass can come in, but with the new setup I think I can take the sacrifice so the people in the back are happier lol. With this amp, what would you suggest? Budget is around $150...little low but I am willing to buy used. Just need something that can keep up. I plan on deadening the doors as well. So throw some suggestions up on what I should do!
