did you changed the subs on the car and if so what subs did you put it. I have the same exact amp in my car but I had it installed behind the driver seat since I really don't need to go back there. The reason I ask is because I can't get the factory subs to work with that amp so I have really good mid's and highs(I have after market Infinity Components) but no bass. I don't even want that much boom in my ride just enough for myself and whatever lady I'm riding with. The only subs I have found are JL audio but I would rather get the factory subs working instead of spending my christmas money...LOL... any suggestion?
