  • I got this amp for a 15" Rockford Fosgate P3 and let me tell you..... WOW this amp really pushes the 500watts rms. These are true watts and for the price its a steal! The paper it came with said it was tested at 530watts rms. I am really happy with this amp. it has gone for a while and does not heat up!

  • I love this amp. I have this amp hucked up to 2 p2 12's in a ported box. In a 98 mustang they pound hard. this apm makes my subs put out more sound without alot of rattle. It is the best amp for the money!!

  • keep it at a 4 ohm load it gets a little hot at a 2 ohm load over a long time and still puts out a lot of power, like the bass control that comes with it. very good amp for the money

  • Just got this today, showed up 5 days after I ordered it with everything in the factory box just like they say. Will definitely be buying from OCS again. I'll post another review after I get everything hooked up and listen to it for a while.

  • I had this hooked up to a mtx 5500 in a bandpass and it hit, i hooked it up to the SSL CL10D and it was ok. I have found that it's a good budget amp but the effeciency is low. rockford said to pair this amp with 2 300 watt max subs, Ima try it and get back to you guys.

  • 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.

  • 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.

  • 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.
