  • Works great, sounds awesome!
Works as expected. The wiring connectors are high quality compression style.

  • Extremely well designed Amplifier
Rockford Fosgate has really done an awesome job in the design of these amplifiers. I have this one running a total of 6 speakers. Two 6.5", two 6"x9" and two 3.5" Rockford Fosgate component speakers. So it's running two speakers at a 4 ohm load and four speakers at a 2 ohm load. I have a 50 mile one way commute and after listening for that amount of time (approximately 1.5 hours) the amp isn't even warm to the touch. I design electronics and I must say the thermal dissipation for these class D amps is phenomenal. Very much worth the price for the quality. ... show more

  • Great product
I thought that because I was down grading, from a 600w to a 300w. I can not tell. Only difference is the 600w had a ‘’PUNCH’’ button

  • Great Sound at a great price.
I needed to replace the Bose system in my car 06 Envoy. So I replaced the two front door speakers with the p 167 5 from Fosgate. Bypassed the factory amp and replaced it with the are two three hundred amp from Fosgate. Not a lot of money to spend but what a difference in sound quality. So anyone looking to improve their sound system on the cheap you should really look Fosgate amps and speakers. You will be amazed. ... show more

  • As advertised!
What can I say? Well it’s just as advertised and works great! I’m using it to power 4 door speakers, which all of them are great aftermarket speakers and sound so much better with a little power going to them.
