GOOD AMP

The following review is for R300-4, which is a part of the bundle you are viewing.

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.

Rockford amp R300-4

The following review is for R300-4, which is a part of the bundle you are viewing.

Awesome sound and great price. I replace my old Power Acoustic 400 × 4 with this Rockford amp, and believe me, it sounds like a whole new system. A lot more powerful and stronger mids plus clear highs, what else you can ask.

Awsome amp!

The following review is for R300-4, which is a part of the bundle you are viewing.

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!

amazing!

The following review is for R300-4, which is a part of the bundle you are viewing.

I love all RF products! this cheap amp literally pushes my cars speakers to their limits!
i dont have top notch audio, cause im a college student and i cant afford to spend 500 on a pair of mids/highs. But i do have 150/pair speakers in front and back on doors. JBL, to be exact.
Great amp!

good amp but not a thumper

The following review is for R300-4, which is a part of the bundle you are viewing.

Amp works good. Watch your specs. The amp does what is says and that's it. Can't go on low ohm subs when bridged mono. If the rated specs are what you need then I would give it 5 stars. It sounds good and performs excellent. However, that's only 150 watts max per sub. Most subs require much more.

Excellent mid and tweet amp. No doubt
