Rockford FosgateR500X1D Prime 1-Channel Class D Amplifier

Still kicking with a 12” P3 distaste, never had issues after a few years of banging the sub. Sounds great, doesn’t get to hot, super easy to install and never have distortion.

Big sound. Works well.

SETUP:My setup for this install included this Rockford Fosgate R500X1D (620w RMS) amp and a single 10" Alpine Type R (4ohm) sub installed in an Atrend 10" (10SAL) box with .71 cubic feet of internal volume - just within spec (.50 - .75 cf) and light (relatively speaking). I was able to get an 8 gauge Kicker amp kit with interconnects (RCA cables) and got a PAC LOC (line output converter) so I could retain my factory 6.2" touch screen. I put Alpine SPS 610c (6.5" Type S speakers and tweeters) up front and Alpine 610 (6.5" speakers) in the rear doors. This was all installed in my '16 WRX.WHY THESE COMPONENTS?I didn't want to add a lot of weight and I wanted the cleanest bass I could get for the money. I've done 50+ installs both professionally and for fun. I enjoy it and I also like doing my own research and finding out what I think will be best instead of listening to "experts". It's more of a challenge for me. Will I add another amp for the component speakers? Yes, but later. For now I have mods to focus on and just need a decent sound. The factory speakers from Subaru were complete garbage but the head unit is good.AMP REVIEW:This amp is strong and hasn't shut down or overheated once. My old JL Slash amp was great but was sold with an old car and my Alpine pdx (1,000w amp) was sold last year before I bought my new car. I would say this amp stacks up very well to the PDX. It's surprisingly small but has plenty of power. I have the gain at 3. I have the bass boost at 1 and the bass is tight and fairly clean. Is it as responsive as the JL amps with JL subs? No. But does it hit hard and sound clean? Yes. Is it worth the money? Absolutely. It flat out performs and for under $130, it's a great deal. The reviews here say it all. This is a great amp.CONCLUSION:My total investment into this system was just $380 and the system sounds great. I listen to Trap mostly - lots of bass, lots of drops and lots of fast-paced hits - this amp handles all of that pretty well.I highly recommend this amp if you want a good sound for a great price. It really is the best one for the money in my opinion. If you are new to amps, look no further, this is the one you want. Rockford Fosgate has been around for a long time in this game and they have always made quality amps - this is no exception and may be the best "budget" amp ever made.

Before I give you my review, if you're not an experienced installer, do me a favor and educate yourself about amplier gains. It's not a volume control. Just because Joe Schmoe says he has his gain turned this way or that way, it should mean nothing to you because you don't have the same system. You don't know how many volts are being sent. There are just too many variables that you don't know. The gain is also not a bass boost. The remote knob on this prime is for gain, yet on punch amps the remote knob adjusts bass at 45Hz. This amp still has an adjustment for boost, but the adjustment is only on the amp.Ok, now on to the review. Nice and compact. At 4ohms its not running hot at all. As soon as I replace my sub I will update and let you know how it is at 2ohms. Oh, the birthsheet says 646 watts, but don't let other reviewers tell you that's at 4ohms. Its not. That's rated at 2ohms.Now, the lights. Both on the amp and the remote knob- way too bright. Love the blue color, but at night, ouch. You can't make any adjusments on the amp unless you cover the light because its blinding. On the plus side, it lights up the entire backseat floorboard. The remote knob produces so much glare on my side windows, I can't see out of them at night. This can all be fixed with either black tape or a sharpie marker so don't let that stop you from buying this amp.Final thoughts on this amp: for the price, you can't go wrong with this CEA compliant amp. It puts out rated power. Don't be suckered into amps boasting outrages max power. Educate yourself. I know I sound like I'm ranting, but I've been reading reviews on Subs and it blows my mind seeing all these reviews about "I have my gains on max" or my (insert name)amp is feeding this single sub 1500 watts. If half these claims were true, no one in America could sleep because every 5 mins there would another person driving by and rattling home windows all night long.

Sounds great! Worth every penny!

When i got this little power house i was thinking dang this thing is small opened up paper work looking for birth sheet mine was born with 638 watts it sounds good at 4 ohm and i have it running to a 15 in kicker comp bumps it hard im going to try it with my pioneer champion series 10 in dual 4 ohm voice coil drop it down to 2 ohm so i can use all of that 638 watts i bet it will be pretty epic going by the way it pounds my 15 in at 4 ohm it's only putting out something like 375 watts mabey a little more or less but on that 10 in at 2 ohm full output so i can say that i would buy this amp again people remember rockford has been and still is one of the best amps you can buy always under rated on the box whatever it says on box it will do that and more every time so do go out and get this amp for the price you really can't beat it bye all

It's the perfect amp. I've had a 12" rockford fosgate p3 powered by it for 7 years now. Still sounds as perfect as the day I got em.
