I bought this amp to go with my Rockford Fosgate R2S-1X12 R2 Shallow Prime Single 12-Inch Subwoofer and this sounds great!

I paired this with a Pioneer TS-SWX251 10" sealed sub box and it has plenty of power. Very well made. It does come from the factory with a remote so don't let Amazon suggest you buy a separate one.

I have the amp pushing one 400 W RMS 10" shallow sub in a small box in my 08 Tundra. The small size works well with my limited cargo space. It has a relatively cool operating temp and comes with a bass level knob that can be mounted anywhere on the front console or dash. On top of that It actually produces more power than stated. Fosgate tests each amp before sending them out and this one is certified at 629 W.

This amp is rated for 500 watts rms but they test them beforehand and my came out that it could handle 630 watts. Runs cool paired with 2 10's. simple to setup and use. Very nice remote gain too, mounted inside my glove compartment. Would buy again in a heartbeat!

I bought a 10" P3 not too long ago and installed it in a sealed box. I hooked it up to a AR1500m BOSS amp and it worked fine. There was always something a little off about the sound of the sub. The signal would seem to 'trim' down when reaching certain volume levels (not just high volume levels..even in the mid-level area). It's connected to a Factor Bose system (Mazda 3 2013) so I attributed it to the funky Bose signals, if you know what I'm talking about. After a long drive in the Texas summer heat the BOSS amp kept cutting out and going into protective mode. Just because of that I decided to replace it and go with this R500X1D. I swapped out the amps and before I got to tuning the amp the sub was hitting so much harder. It was even crisper. I tuned it and turned up the volume trying to catch those trim down points I was used to with the BOSS amp and they were gone completely. The kicker is that I think the BOSS AR1500m amp claims to be a higher RMS rating than the R500X1D.

To provide some context to this review -- I've had several car audio systems in the past (Kicker L7 12" connected to a Kicker amp; two RF HE2 DVCs connected to an RF amp; Bazooka tubes connected to Pioneer amps) all of which were quality products. It was my first time going with a 'cheaper' amp to power a nicer sub. Please don't take this review as disparaging to the BOSS amp. I think it's a great amp if you're looking for something as basic as can be. It'll get the job done. If you want to get the full potential of your car system don't skimp out on any of the items. The difference is there. This amp is awesome. My next step is to strip my car of the BOSS amp wiring and run RF wiring.

I replaced a boss 1500ar with this unit. I was just giving the boss amp a chance but I knew it would not suffice. Rockford fosgate amps are the best, hands down.

I have this amp pushing a 10" fosgate r2d4 sub in a .79 cu ft sealed box @ 2 ohms.

The volume knob actually works unlike the boss amp.

Just think, if you pay just a little more you get a tested and verified unit that actually puts out the wattage it advertises. This one came with a spec sheet that tested and verified the amp to run at 642 watts rms. That is a deal in my book.

AWESOME!! BUY ONE NOW SKIP THE CHEAP GARBAGE AMPS!!

I've got this powering an R2S-1x12 shallow 12" subwoofer, it sounds great. I'm very happy with this purchase. Amp feels durable and solid in my hands and produces a good sound.
