Rockford Fosgate R500X1D Prime 1-Channel Class D Amplifier

I had a cheap Pyle amp for probably 4 years and it didn’t give my subwoofer the sound it needed but I never knew it until I got this one. That amp blew up (so cheap I’m surprised it lastest this long) so I decided to get a brand that I could trust.
This amp is a little beast to say the least. I like the variable bass control that comes with it as I listen to different kinds of music. It pairs with my Fosgate P3 perfectly.
If you’re in the market for a nice amp don’t even hesitate to get this one. It’ll blow you away!

Really decent Lil amp powers a Kicker CVR-15 just right. Pairs nicely with the 300/4.

05/29/16 Update. Still going strong after a year of powering the CVR-15, Slightly disappointed with having to say it’s a 500 watter. Any other old timers like me this is equal to the punch 75, autotek 90mxi or hifonics thor which all were only rated for less than 100 watts but could out power this new school stuff.

04/17/17 Update
Year 2 of still going strong with no hint of ever quitting. Built a better more efficientbox for the Kicker CVR-15 that is 4cu ft and port tuned to 22hz. The sub and this amp especially with the new box are a perfect match.
The Prime 300/4 is still going strong as well these are really decent reliable amplifiers.

Got this amp to hook up to my Ford truck got it hook up with some planet audio px-10 shallow woofers with a ground shaker box got to say this little amp pushes them HARD I’m impressed how this amp sounds and woofers don’t cost much still breaking in speakers and kicks very hard, happy with the Amp, speakers bought somewhere else but can get in Amazon good price for anyone looking for good price shallow 10″s and this amp good combination.

Update: Bought this 1 year and 9 months ago amp still hitting hard hooked up to 2 10″ kickers lowered at 2ohms I recommend it it’s small but powerful little beast.

Great amp, RF produces some quality products that hit hard. I am using this R500X1D with a single Polk DVC 10″ sub in a 2 OHM setup and it pounds like a 12. The passive cooling generates a pretty good amount of heat but have not had any issues with overheating yet (I have 1.5 hour commute to work each day).

Update Jan 2018: Amp still chugging, replaced the sub with a Kicker CompRT 12 and it pushes that sub effortlessly as well. Have not set gain over half on either sub.

My husband bought this for the subwoofer in his Civic. Disclaimer: I know nothing about car audio. I have only the most basic understanding of “car audio” in general due to being married to a car audiophile for 16 years. I have an even weaker grasp on what this amp does exactly, but I recognize the brand name. As for my personal review, I appreciate that it’s not some giant, ugly, 3-foot, 50-lb thing that may get installed, then uninstalled, then sit in my garage…or, god forbid, under my BED, for YEARS before being taken back out and put into another trunk. I mean, what? That’s never happened to me…like three times or anything. I digress. My husband asked me to review it on his behalf, but as my knowledge with it’s specifics are iffy, I asked him, “Ok, do you love it?” He says he does. He likes that it is compact and that it has a lot of power to produce adequate results from his sub. I appreciate that it didn’t take him forever to install, and because of it’s size I was not required to help hold or lift anything in the process. Everyone wins. End vote, let your audio-loving spouse buy this because even if they take it out, you can store it somewhere where your cats don’t nest on it and people won’t ask you what “that thing” sitting over there is.

Very compact with a Powerful delivery. I will be ordering a 2nd one so my P3’s don’t have to share power once the component amp install is complete. The one I received was tested to an out put of 647w RMS. It stays super cool setting are self explanatory, bass control housing is metal not cheap plastic. Rockford Fosgate Quality and Precision for knock off $!

This tiny thing is a freaking Beast!
Decided to install a stereo in my gfs car for her bday. Paired this with a American Bass XR-10D4 in a bbox e10sv ported enclosure.
As far as ratings go the sub is clearly being underpowered but damn the thing hits hard and it’s more than enough for her. The bass remote does leave a lot to be desired though. I used to install professionally and have tuned more amps than I can count, but this knob is touchy with very limited range. In about 1/8th the range of turn it goes from no bass to max…
Could be an isolated issue and its just a defective part that I received. Not a huge deal as she doesn’t play with it much.

This Product will exceed your expectations. The size of the unit is smaller than most units that put 50% “more power(All the cheaper brands, that are not 2006 compliant).” The amplifier has been put through the ringer, through a few speakers, and couple blown fuses(from the battery) and a few crossed wires( accidentally shifting in the trunk, now fixed). The Amplifier has been in protection mode more than I care to admit and it still bounced back. The terminals are very secure, My only advice is that you get a quality RCA because mine broke off in the first RCA port, But luckily there is a pass through that works identical to the first ports.
