I don't have a whole lot of experience with car amps, but my home systems have always been the envy. My friends would spend twice as much as me, and would eventually just have to concede that my system had the best sound. I know what I'm doing. My electronics background, and years as a musician with perfect pitch hearing is my gift. I feel I hit it right on the mark again in building my relatively inexpensive car system, starting with this amp!!!
The amp is clean, and loud. Plenty loud for the little Nissan I have it in.
In a larger sedan, I might want to step up the watts, but I like it loud. I have this pushing the two front, and two rear speakers, with a separate powered sub. It was stinking hot this summer, and it's stinking cold now!!! I had no problems what so ever. I didn't wait till the car cooled down any before I cranked it up, and the amp handled all that heat in my black car.

I have this amp powering all my pioneer door speakers, i play it loud for extended amounts of time and no overheating at all, great sturdy amp at a unbeatable price.

I was looking for an inexpensive amp to run the factory speakers in my 2003 Maxima.
-Amp works great
-Sonic ships to Canada and takes care of brokerage/duty at a reasonable price
-I will continue to use Sonic

wow ok so before this i had a sound storm 4 channel to power all 4 speakers now i have this baby and man does it make a difference!!!! the sound is so clear and loud. Now my 2 12s are in perfect match with my speakers!

I'm basically a rookie in the car audio game workin for a shop with over 20 years in the game and me only 5 . but lemme just say i know my audio and i know how to make it last. but this amp is great by far better than anything else in this price range you cant go wrong unless your not hooked up properly the end great buy, but im ready for more power for my db drive mids and highs got over 18 speakers hooked up off two of these you can hear me way before you see me

I wrestled for sometime on which amp to go with as I was extremely limited on space, so I went with the fosgate 300-4. Im running a pioneer head unit, cadence 7v line driver as far as high end speakers I choose a pair of kicker 6.5's for the doors and kicker 6x9's for the rear and went with a kicker c124 sub. I am absolutely amazed by the bass and how clear the high end is. If you were in doubt about running "only 150 watts" to your sub(s) have no fear, this amp does a fantastic job. For the money you'll not find better.

I recently bought this amp and the sound, power, and price you cant beat. I am powering some diamond audio 6-1/2" components and factory 6x9s clean & pure sound. I recommend this amp to anyone who is looking for great undistorted sound. Pros- doesn't take up plenty space for the amount of power that it has, Cons-couldn't find any you cant go wrong buy this amp.

I have had several Rockford Fosgate products in the past. My last Rockford amplifier lasted 14 years. I have purchased many of their items from amps to speakers to head units. Very reliable product. I will continue to purchase Rockford products as well as recommend them to others.

Pros- powerful, clear, adjustable for 4 speakers or 2 speakers and a sub. This amp over powers my kenwood speakers and makes them sound crystal clear all my friends are jealous of my vocals and think i payed over 200. Fast shipping from Sonic and the price is awesome.

Cons- really long amp for my lil car thats it

I bought this amp and put it on a pair of infiniti 6x9 and is sounds amazing. Good amplifier for the price.

Loud and clear just like the company claims.

Definitely a Rockford Rosgate amp, loud and clear. The lower end Fosgate amps would compare to other brand's high end amps. And just like all RF amps, this one is way underrated. My birth sheet shows 386 watts RMS, and the amp is rated for 300. Highly recommended!

Wow I bought this amp to go with my other Rockford Prime speakers and it can easily over power and distort the 6x9"s and 6 1/2"s I may need to upgrade the speakers again.

This is a good amp for 4 door speakers, its not small but it still fits under the seat in my truck. Sounds great, I love it!

Cheap, simple to set up. Works excellently. It is a little large but still well concealed under the passenger seat of my '04 Camry and never ever has any heat issues (probably owing to the size). Hook it up for a full front stage sound system with subs and forget it exists. Just what I wanted. Also, I don't see the lack of crossover flexibility as a real negative. Most amps give you enough rope to hang yourself. This really has enough to cover what one would need in 99% of cases for 99% of the public.

This was a great product for a really great price.

I have this amp running 4 infinity reference 4x6 plates. My vocals are amazing! This amp doesn't get hot at all, and underrated in power. My birth sheet says 345 watts. To good to pass up on this product, a win win situation!

This product is wonderful i have rockford before but i just love the look and style of this model

this product has worked perfectly from the moment i plugged it in! I am considering buying a new amp from u.
