I have this amp in my single cab toyota pickup, hooked up too one Alpine Type E 10, and Type S 5x7's in the doors. For the price, this amp has PLENTY of power to push my speakers AND my Sub. the Gain on Both are half way, with plenty of power to spare. if you are concerned if this amp will have enough power for What ever you are running, you have nothing to worry about. With the crossovers Tweaked just right on the deck, this amp will produce clear and dynamic sound. And talk about LOUD, you wont belive how loud your speakers will get with this amp compared too a deck. Highly recommended amplifier. Worth the money!
