       sam From stl

    Bought this amplifier and recieved it today. At 2 ohms for 10-15min it gets really warm and after 30min you can cook eggs on it and can barely touch it. good SQ and response though. Good thing it's installed in my house so i can put fans on it but besides that great price. disapointed in Rockford's Prime series though.

    I have one of these amps hooked up to 2 12" Rockford Fosgate subs in a ported box. It pounds like I spent a lot of money, but i didn't. Couldn't beat the price either. I recommend this amp to everyone. You don't need to turn the gain up very high, and the Hz frequency control is great too. So all in all I really enjoy this amp, and I think you will to.

    I have one hooked up to 2 12" Rockford Fosgate 300 watt subs in a ported box. It sounds great. I recommend this amp for those who want great sound for cheap price.
