Rockford Fosgate R250X1 Prime 1-Channel Mono Block Amplifier

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.

Nice amp, probably one of the best bang for the buck one you can find. If you have a moderate system and like good clean bass this is it, if you into the shake the neighborhood thing this won't be it.Install was straight forward, setup took some time to get it right where I wanted it, included remote knob is a nice feature, most other charge extra for one. Not running anything to fancy, just one 10 at 2ohms and the birth sheet said 635w, so what's not to love about a extra 135w, thats more overage than my stock "infinity system" JBL amp sent to the factory sub, paired with a pioneer shallow mount freeair 10 so not the ideal setup and the amp is double what the sub can handle so down the road I can upgrade or go with a harder hitting box, options and future upgrades are nice.Update 9-19Stepped up to a much better sub, 12" ported box rated at 600rms, and this little amp makes it pound with ease, and it's a a very decent sub, I'm still blown away how good these amps are in this price range, about to replace my budget 4channel amp with the p400 4d next week and and can't wait to hear how much better it will sound, big kudos to RF for producing such a great product with a budget minded price, sure the punch line and higher ones have more features but for the one looking to get some good power without taking out a second mortgage these things rock.

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.
