I'm trying to decide on the purchase of 2 amplifiers, one 4 ch for mids and highs and one 2ch for the single sub. I've looked at Tru, Brax, Zapco and JL Audio just to name a few. The size of the amplifier is my biggest issue. All of the amps will fit, but the JL amps are the smallest cases and the least expensive. I can save alot of money by going with the JL products. My concern would be the quality. Will their product stand up like the other ones? The dealer is very reputable where I would purchase the JL's. I really need some opinions here. Thanks you all !
