A solid amp

Bought this to power my 2 alpine type e 10s and man am i happy. Makes the subs bump hard in only a 1.1 cubic foot box for both. Would recommend this amp to any one looking for a reliable amp. Came in at 546 rms.

I Really Like It

When I first pulled this amp out its packaging, I had to laugh a little. It's got a footprint that's only a bit bigger than a CD case. It weighs a couple of pounds at most, and has a very understated look. The birth sheet states 558 watts RMS @ 2ohms. I hooked it up to an MTX RTS12-04 in a factory spec box. I used 8-gauge power wire from RF and 10 gauge speaker wire. I put the box in the trunk of my Honda Accord with the port and cone facing into the cabin - back seats folded down. Let me tell you, this little amp does some serious work! My roof/trunk/door panels all flex like crazy. I can see my shirt and the plastic bags on my floor vibrating on the low notes. I can even feel my hair shaking and smell my poor sub's voice coil. Mind you, it's still only wired at 4 ohms! I can't wait to hook it up to a good 15 at 2 ohms.

I think this amp is perfect for people wanting loud bass without having to modify their car's electrical system. My car came stock with a 130 amp alternator, so this little guy won't even come close to over-drawing my charging system. Also, it can't draw more than about 50 amps, so you can use 8-gauge power wire as long as it's high quality. You have to love the efficiency of a class-D amp. It barely gets warm to the touch after blasting for 20 minutes at full volume.

If there is a better amp out there for the money, I haven't heard of it. Having owned it for only a few days, I have yet to test its durability. However, Rockford Fosgate is well known for the quality of their products. The bass remote knob is an awesome feature that you must buy separately with most other amps. The low-pass filter and bass boost controls work well and aren't obtrusive. The heat sink design is nice and clean, which is great because I hate bright flashy colors. Also, the blue power-on LED lights up my trunk at night, which is cool. All in all, this amp is better than expected and I could not be happier. If you want loud bass without a big amp, this is it.

Great Amp

amazing output for its size

I'm running this in a 99 olds intrigue (stock electric) with a hypnotic 12" zen in a 3.25 cuft box tuned at 34 hz and its nuts.

I was disappointed when I seen I bought the smaller r500.1d instead of the older r500.1 which is roughly 9" wider.

Regardless this little guy slams, it's definitely worth the price I recommend to all.

Amp came with a birth sheet stating 560 rms @ 2 ohms

Look/design received a 4 because of the spade terminals.

Awesome

Using this with 2 JL Audio w3s (the 6.5" sub)
subs rated for 125RMS and this puts out just enough to make them hit hard for how small they are. Tiny size makes it fit anywhere, could use some better terminals tho

Can't go wrong with Fosgate

The following review is for R2-500X1, which is a part of the bundle you are viewing.

It's small but back in the days you needed an amp that was 4 feet long (lol) to come close to this little monster.

Paired this with an R2-300x4 and a Kicker L7 10. Love the clean clip light for input and output. Makes installing and tuning the amps extremely easy
