  • I've done 50+ installs both professionally and for fun. I enjoy it and I also like doing ...
Style: Class D
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. ... show more

  • I'd recommend this amp. Its affordable, small format, and powerful; and gets the job done
Style: Class D
Picked up a '16 Mustang Convertible with the low-end Shaker 500 system. Sounded....umm, well, bad. Desperately needed some upgraded bass......at a minimum. There weren't many affordable plug-in-play options for the '16 convert, so I went another direction. I added a pair of 10 inch; Pioneer subs (TSW261S4 firing up) to an off-the-shelf $40 prefab box designed for Jeeps (Qpower). Then added 2-farad cap, Rockford Fosgate Prime (R500X1D) amp, an LOC from the passenger rear speaker. I then got that Ford enhancement rumble that I never wanted; coming through the 10s. It was really bad/obnoxious from about 900 RPM to about 1900 RPM. Apparently, Ford engineers thought is was a good idea to feed engine rumble through the car stereo and calls it & Active Noise Control. After reading the Mustang forum; I found the Active Noise Control mic in the map light panel and simply unplugged it. Problem solved. The Rockford Fosgate R500X1D came with a simple knob turn type remote gain control that's mounted under my dash. The remote knob has a blue light that is almost blinding bright at night. Also in the box was a spec sheet with Fosgate factory measurements. Apparently, my amp measured 616 watts at 4ohm at the factory. Running the amp with the Pioneer 10's wired in parallel (2ohm) puts plenty of bass back into the Mustang; completely fixing the Shaker 500 shortcomings. Most of the reviews said this amp was so powerful, gains needed to be set low. My experience: running (2) 10 inch in a sealed box (.98 cu ft/ea) needed to use everything this amp could give. My gain and boost are set to max, but no problems and no clipping. I'd recommend this amp. Its small and powerful; and gets the job done. ... show more

  • Great Amp!
Style: Mono Block
I ran this amp into a single 10" sub at 2 ohms and it hits real hard and sounds great!

  • Good little amp with very bright lights!
Style: Class D
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. ... show more
