I have been using this amp for about 1 month now and I can't say enough good things about it. It is driving 4 Kicker 6x9 3-way KS 693 speakers to DEAFENING sound levels and it seems to just be "loafing" while doing it. The amp runs cool to the touch - even after extended use. The fact that the gain, crossover and bass boost controls are located on the front of the unit is way cool. It makes everything so easy to adjust.

The amp is beautifully constructed and produces very clean sound. Best of all though was the price I paid for it here at Sonic Eletronix (less than $300.00)

You really can't beat this amp for the price, performance and features. Buy them while they last...

kicker makes a very good affordable product. This amp and this price is an unbelievable deal. I have this hooked up to 4 cheap speakers in my car and it was loud, sound quality was surprisingly good, and i had the gain turned to around half. The knobs on the front and dont require a screwdriver to adjust. 215W RMS x 4channels is plenty of power to wake up the neighborhood, and you can't beat it for the money.
