Great Little Amp!

I installed this amp on my Harley Street Glide to drive two 6.5" Polk MM651 2ohm fairing speakers. I'm pushing over 150 watts per channel with this beast! The amp fits great and sounds incredible! I don't believe you will find better sound quality and power in such a small package for the price!

Great little amp

The size of this amp gives you the ability to install it were there in not much room,the amp has enough power for my door speakers

Harley Davidson

I purchased two of these for my 2012 Ultra. I have one on top of the radio feeding the front speakers and one located in the trunk feeding the speakers in the lowers. I picked this model for the ability to be 2 ohm stable and produce 150 watts per channel. They do run hot and will need air around them. They blow away all the other amps I have used on bikes up to this point. Be prepared to piss off the cars around you even at 70. My friends tell me you can hear me very clear several blocks away. Running Polk MM 6 1/2 for speakers.

Rockford Fosgate PBR 300x2

This is one kick little amp, very small and lots of punch! it drives 4-Rockford 6.5" on my Harley davidson and I'm going to purchase one more to drive a set of 6x9 in my saddle bags! perfect crisp clean and did I mention LOUD! best bang for the buck and fast shipping.

Go get yourself one.

The best small amp with true power

I would Recommend this to anybody who's looking for a good amp with small space this amp is a true 300 watts I'm glad I found this amp I am very happy with it

The best price

When trying to acieve the best sound you cain't go wrong with Rockford fosgate although I had bought one less then a yr ago it quick working, I took it to get it repaired and it was cheaper to just buy another one . After had listened to other amps I'll never use nothin but Rockford fosgate

Loud and Clear

Installed on FLHX to push the J&M fairing speakers (140w each). Installation was not too bad having to splice wires but mounting the amp was challenging without a bracket. The sound is superb but now I may need to upgrade the speakers...good dilemma.

Awesome Amp Great Price and Service!!!

I bought the Rockford fosgate PBR300x2 for my Harley this amp is small in size but not in performance, great amp great price!!!

Impressed.

I have this amp bridged to run my 10" JL in a sealed box. I am impressed with the output of this amp for its size.

It's a straight forward install, easy to adjust gain and the cross over frequency.

I would highly recommend this to anyone who is thinking of using it for a sub amp. I just wanted something to round out the system in my wranger and easily fits the bill.

Just make sure to buy 10 gauge wiring (so you don't have to be like me and re-buy power/ground wire).

Awesome amp

I installed this amp on my 2014 Victory Cross Country and it made a huge difference. It's small and packs a "Punch."

Great compact amp

This amp may be the Terrance “Bud” Crawford of the amplifier world. Pound for Pound greatest amp. It may be small but it’ll pack a punch!
