great amp for great price

This amp is powerful. Mine was rated at 402w rms. I have 2 6.5, 2 6x9, 2 5x7. Is not even half way up and they scream. Ordering 2 sets of Rockford p165 and 2 sets of p1692. Should sound better and cleaner. Rockford never disappoints me. Great product!

nice amp for the price

I ordered this amp for my boss and installed it in his truck along with some of the 6.5 prime series 2ways. The sound and clarity is perefect for the price it gets loud without distortion.

fab!

my son recommended the R300x4 to complete the sound system in my pt crzur. I would highly recommend it to anyone.

Typical Fosgate

I've been a fan of Rockford fosgate since I was a teenager " I'm 43" always the best bang for the buck. This 300x4 amps birth sheet said 426. Its push 4 infinity 6x9's and and pair of infinity 3.5's with ease. Love Fosgate power

Fosgate 4 channel amp

Plenty of power to run your system & extremely easy to set up I use it powering Polk db5252 components in the front & Polk db692 in the rear ran through a Kenwood X-599 deck & I have a Rockford 12" punch series sub in the trunk (not ran through this amp) & it really brings the musical experience to life

Good stuff!

This item did exactly what it should. Great value. I would definitely recommend!!

Great amp

I searched a bunch of websites and its hard to tell who is telling the truth about this amp. So I purchased this about a month ago installed it my 99 sierra truck. Its used to power my front and rear door speakers which are also RF. This amp has more than enough power but what I was really going for was clarity. This amp completely met my needs. If something happens to this amp I'll buy another one. Purchased from sonic electronics they got it to me quickly with no problems.

Great amp for budget build

Looking around for budget build on my truck since I over spent on subs and head unit. I knew back then rockford was amazing company. Actually still are for a budget is it going to get you stereo competition no but it will get quality to your speakers. I love technology to find sweet spot of not clipping your speakers. I would constantly be running to stereo shop have them professionally tune it with there equipment. Want I diy project with your kid or just something get you heard around town I recommend.
