Rockford Fosgate Prime R500X1D 500W RMS Mono Class D Amplifier + Amp Kit + Cap - Customer Ratings & Reviews

Quality Product

Works very well with my Rockford Fosgate sub system in my car.

good deal!

Pretty decent value for the price. Worked out great, thanks.

Usable

The wiring has done me right so far but the only thing I don't like is the speaker wires. You have to carefully split it so the wire doesn't show. Other than that minor thing everything was great and a great value!

The beast capacitor BELVA

Rzr2023 200 we added a capacitor to the sound system. We have all this connected to it, and it stays playing music a good three hours stuff we put to it
4 Belva 6.5
2 whips 6ft
1 back amber light row
1 spot flood light bar
2 spot light rear view mirror
1 4ch amp
1 radio head unit
And works perfectly fine. Holds a great charge to keep all this running without the razor running for hours

price is right

the price is right for this setup. the ground wire and the power wire are to big for my amp but i made them fit. better to have to much than not enough so if i upgrade to a larger amp it will be fine.

Accessories for product

Just what I needed and made installation so much easier. Thanks

awesome products

I run 2 12inch audiobahn exursions on this amp and it pushes them very well. The size is perfect not to big and fits right unerneath the seat or small space. The best part is it stays pretty cool even after running most the day.

good wires

I like the wire kit I got with my amp it seems to be holding up goo it handles the power of the amp I got but I would of gave it 5 stars all the way around but I wold of like the ground at less 2 more feet for good use but over all its a nice kit

Good stuff

Great product last a long time good value for the money.

Cable

Good product fast shipping awsome seller... keep up the good work.....

Perfect kit

Comes with everything you need. Works good with my 800w system

Great Value Kit!

I would highly recommend this package to anyone looking to do a cheap install, i have friends who got these before and its nice, simple and cheap!
Never had any issues, great value!

By Craig on October 15, 2016 Verified purchase

Good deal.

I purchased this for the value. Everything you need for a simple single amp install in one package. Good quality with good value, thanks.

Ok value

Good product , but not enough speaker wire to wire two front door speakers in a scion xb. I guess it would have been enough if I had run one of them with the power wire instead of running on the other side of car, but everybody knows that's a bad idea due to engine noise. You would think they would take that into consideration. Also not a big fan of the square and round speaker wire very hard to separate and strip without exposing bare wire.

Ok. not the best kit.

The eyelet connectors are flimsy and the speaker wire is hard to separate. When it does it exposes some of the copper. Otherwise the kit is ok.

Works great

My issue was the strain my amp and subs would put on my battery, no more drainage issues, speakers still sound great, car runs perfect

By Jaree on February 17, 2020 Verified purchase

Must Have

This is keeping the power flowing. Preventing that drain that comes from running 2 amps.

By ClNShvN on January 16, 2020 Verified purchase

Great value

Does the job does what it needs to do. It was packaged nicely.

Good Cap

This is a good cap. The issues I had was the resistor did not light up when charging. To charge this cap, put the resiston up for 10 seconds or so. Once charged, when you go to finish the install the cap should be in the 12 volt range. I bought this to replace a 500k scosche cap. That cap ways way too small and point less being that I have a 2000 watt belva monoblock. This amp work really nice. It goes great with the belve amp. For 40 bucks, you will not be unpleased with the purchase.

Great CAP for the money

I would highly recommend this CAP and the BOSS 1100 Watt combo. I have it hooked up in my F150 with driving (2) Kicker 12" COMP Subs. The amp combined with the 2 Mf Cap makes these subs rock. The Bass is clear and solid with virtually no distortion. My daughter liked it so much that she asked me to install one in her GMC Serria. I am about to purchase a third to install for a guy at work.
Would I recommend this amp to a friend?....Hell yes without a second thought.

By Steve on January 5, 2020 Verified purchase

Great Product

The product works great! I am very satisfied with the performance of the capacitor.

You get what you pay for....

Bought this kit for my 650 watt rms amp. Not true awg 4 guage, but close.jacket is pretty thick.all wires flexible. Reached under the back seat of my 2008 silverado crew cab. But not a whole lot of slack if your going to a trunk. Fuse is ok... ive seen better and worse. Bottom line, if your on a budget and running 800 rms or under, this will work fine.

By Trevor on June 8, 2016 Verified purchase

Great wire

Ran wire though firewall with ease m, and is powering my 1500 RMS amp no problem.

By Carey on March 12, 2020 Verified purchase

By Jay on October 6, 2017 Verified purchase

Good kit

Basic kit to get you going. Speaker wire needs to be just a little better.

By Anonymous on March 25, 2019 Verified purchase

Perfect!

Was surprised with the quality of the copper and actual size of the wires compared to other cheap brands like Schoshe. Worth every penny.

The value,quality and durability of all the products Sonic Electronix offer sale themselves.

Decent Product

Works very well, wish it included longer zip ties but overall a good kit that has true 4 gauge wire!

By Lachlan on April 8, 2020 Verified purchase

Great wires!!

After reading reviews and most importantly watching the video Sonic posted with this product, I decided to give it a shot for my Cerwin Vega VPAS-12. The wires are exactly as described, true 4 gauge, not all insulation like the other brands. The fuse block is solid and easy to set up. I was worried it may not fit the VPAS connectors since they mention 8 gauge, but it works and it is holding in no problem.

The only thing I did change was the actual battery and ground terminals, they seemed weak, so i chose something stronger and all is well.

Thanks again Sonic!!

By Fabio on March 16, 2020 Verified purchase

Very well made products

For the price, this installation kit is great. You can spend 4 times the amount for killer connections but if budget and functionality are key, this is the best.

By JAMES on June 9, 2020 Verified purchase

Can't go wrong with Fosgate

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.

Great valule

Great quality wire, plenty enough for the job. Works great and made my install a breeze.

Like a good one to I wood bye it again

Great budget cap to reduce headlight dimming!

I have had this model of capacitor in my car for about 7 years now, with zero issues. This helped the headlight dimming in my Toyota Corolla alot, though it did not totally eliminate the issue. That's not the capacitor's fault: my system includes two amps (subwoofer and 4-channel for the speakers) with a total RMS output of 900 watts, and I'm still running the stock 80 amp alternator. Even with 0 gauge cable for the "Big Three" upgrade, I'm fully aware that the charging system is being pushed to its limits when I have the sound cranked.
However, this capacitor is an excellent value for the money, reducing my headlight dimming for only $35... alot cheaper than spending $300 or $400 on high output alternator. Again, I've been running my current system for nearly 7 years now and have had zero problems with the capacitor, the car or any of my audio equipment. As a final note, this cap is pretty small in size, so its easy to tuck away somewhere. I stuck mine under the driver's seat, right next to my sub's amp (pic attached).

By Justin on December 7, 2022 Verified purchase

Good cap

I bought this cap to go along with my 2 AGM batteries and it definitely helps to stabilize the voltage during long peaks.i tried with and without the cap and like I said it did make a difference don't listen to people that say they don't work.

By Steve on October 21, 2017 Verified purchase

It's okay for the price

My headlights don't go down anymore with the capacitor. I didn't need to buy another battery

Great capacitor

It’s a great capacitor and has never failed. Easy installation.

By Anonymous on September 24, 2018 Verified purchase

Decent

It's actual capacitance is probably not anywhere close to 2 farad but eh, it looks good and works as a distro block. Be wary of the allen bolts on top, they are nowhere near 5/16 so a normal ring terminal will be sloppy fitting on top.

By Brandon on April 15, 2016 Verified purchase

Worth Every Penny!

The product works great!!
I can feel my subs and power is A lot more stable… Sounds more solid!

Not really sure if the display turns off after a while and comes back on when needed. Great Purchase!!!

By Donnie on September 14, 2022 Verified purchase

Regretting the purchase

Cheaply made product. Looks nice in the photo but once in hand you can that it just cheaply made . It also leaves the terminals exposed .

By Lance on December 12, 2021 Verified purchase

Believe the hype

So yes I was the typical person with diming lights when the subs would hit in short burst. I was not going to buy a big alternator and another Batt. I got this and installed it and Soo much better. I can still make em dim but the amp is rated for true 1200 RMS watts so I should got a bigger one. I will say this is alot bigger than I thought I would be. The charging method works but takes longer that you think. make sure you have ring terminals and ground wire and a ground spot. Yes the lcd turns on some times randomly and some times its not on while the sub is on.

By Les on January 1, 2022 Verified purchase

Everything I Needed

Used this kit to run an amp to the trunk of a 2015 Kia Optima. Ended up trimming about 1½ft of excess to help clean up the install. Everything seems to be good quality. Ran the power wire down the driver's side and RCA & amp signal wire down the passenger side to avoid any interference. Plenty of length of everything for a full size sedan.

Amazing.. never thought it would sound like that. Never back down.

Good kit for the price

The power and ground wire are fine , speaker wires are interesting. One side has square and the other is round which makes it very easy to know what you hooking up to what. Came with everything it was supposed to.
