Customer Ratings & Reviews

Great Amp!

I just finished installing one of these amps in an '89 Porshe Carrera...wow! I still am in disbelief how this tiny amp pushed 2 sets of JBL components.. This car screamed and my customer was extremely happy with his purchase. I have been installing for over 14 years professionally and still can't believe this little amp did what it did..10 gauge wire is recommended but I managed to install it with 8 gauge... I could see the amp running hot if the wire run is long using 10 gauge. For future purchasers, buy 8 gauge wire if your run is longer than 10 ft.

Great Little Amp

Powerful little amp installed on a Harley Davidson Street Glide.

Great Amp. Great for Motorcycles

Small. Compact. Easy installation. Great power. Not a lot of adjustments on amp.

good while it lasted

The amp made my speakers (Prime6x8) sound like they were top of the line. i had this amp hooked up for about 14 days until all of a sudden no sound would come through my speakers anymore just a buzzing noise the amp would turn on but no sound all cables were fine.

This little thing kicks!

I installed this into my motorcyle fairing pushing 4 - 51/4. What a difference. Now I can hear it over my loud pipes!

Nice little amp.

Amp has a really small footprint. The amp I have is putting out 87 watts per channel making for a total of 348 watts. I don't need the gain turned up past 3 in order to make my ears ring. I have it hooked up to two Pioneer 4x6 speakers and two Pioneer 6x9 speakers and it rocks them all day and all night.

I had my entire stereo professionally installed and I don't have any problems with it.

Great little package

I was very unsure whether or not to get this amplifier based on the mixed reviews but I did anyway. It has now been 6 months and not a moments trouble. To tell you the truth the size and sound reminds me of the old punch 75 amps. Great sound from a small package. I would definitely not hesitate to purchase this again.

Great little amp

This little amp in combination with a good set of speakers is well worth the money. I mounted it in my fairing of my motorcycle. It easily powers two six inch rounds up front, and two 6x9's in the bags. It sounds great without any distortion. Installation was simple and quick. I would definitely recommend this amp.

Good strong power

Good amp for bikes just can't turn it up all the way hurts my ears.
High distortion but that it due to the Harley deck that has .5thd where I'm used to like .001 THD. I am sure if Harley made a radio with low inputs it would be cleaner sound. All that said I would buy this amp again for any bike hi or low inputs as I always been fond of Fosgate

Great little amp!

I got this for my husband for the holidays. It is small and compact and can be easily hidden within the vehicle. It can get a little warm but he has not expierenced any issues, if you are worried you can always mount it near/ with a cooling fan. He is very pleased with this little amp. It packs a punch.

complete disappointment

My first Rockford amp and it lasted 30 minutes. Now all i get is a loud hiss. Boxed up now ready to ship back. Amp never did sound right and got VERY hot. I do not recommend this amp.

Mixed feelings

This is hands down a superb amp for the cost. I run four 6.5 kicker speakers on it. Never distorts, gets real loud. The only thing I hate is the inputs. They are inconvenient and it's easy to pull out. Keep this in mind when you purchase this amp. Also it tends to hog all the power from my sub when I turn it up. Might need a cap to fix this. Very satisfied with the output and functionality.

Big power in a little sizes

I would by this amp again it's very powerful and can run some woofers like a big amp

300.4

I recently purchased and had installed in my2010 chevy malibu. Pleasantly surprised by the output and clarity of this little baby. Small amp with huge sound quality level goin to my 6.25 kenwood door speakers and 6x9 kenwood rear speakers. Now I defintely have to upgrade to bigger amp and subs to get deeper bass

Never worked

I had originally purchased this amp to have a matching system for my car. I had the amp installed into my car and about two weeks later it went into protect mode and would not come out of it. So I had sent it back and got it replaced with my warranty. After receiving my new one in the mail I had immediately installed it into my car and I got no sound what so ever. It never worked right out of the box and it felt like it was on fire. I would not recommend this amp for anything. If you need a small amp for your bike or car system I would recommend you look somewhere else rather than this product.

Amp

Easy to connect and powerfull sound for its small size. I have only had it for a month so I can't attest about its durability.

This lil rocker realy pumps!!

I AM SIMPLY AMAZED!! This lil dynamo can really pump up the volume!! So I installed this in a 2012 Pathfinder and it fits neatly under the passenger seat with lots of air space around it. I hooked it up after the stock radio out to Rockford 6x9 T1-Power in the front doors and 6.5 in the rear doors. It really drives these speakers well. I am sold on these lil buggers. I read that adequate air flow is crucial. So keep that in mind. I'll probably put a set in my 2012 Sonata soon. (Bi-amped and pumped too by Rockford.) Oh and the ability to go straight in on hi-level speaker inputs really sold me too.

The PERFECT amp for your bike !!

I recently installed the RF PBR 300X4 amp, along with pair of RF M262 speakers, in the Dead Center fairing of my'02 Harley Road King. So far, the combination is exactly what I was looking for - loud and clear. Other reviews commented on the amp getting hot enough to shut down, but so far it has not been an issue. Hopefully it won't be an issue when it heats up later this summer. I made my own bracket out of aluminum flat stock to mount the amp. The PBR 300X4 was easy to hook up and the volume/tone combinations are endless. I visited several different websites and Sonic Electronix was a no brainer to buy from. Lowest prices and great technical help. A definite piece of advise is to direct wire to your source instead of using the RCA cables. The sound and volume are MUCH better. I have graded Overall and Durability at 4 only because I have only been using them for a couple weeks. Ride safe !!!!

Does the job

I highly recommend this amp. i was using a 1000 watt lanzar mini Max and this is way better.

great

best for the money you wont ever get a better one for the cash

good buy

Fast shipping, nice product, also was a good price, would buy again.

Excellent overall value

This amplifier is compact, packs a punch during musical peaks and sounds clean with minimal distortion.

Dissapointed

Bought this product to have a totally stealth stereo install in my '09 Focus. After having 2 of these amps burn up on me I have to say I am quite dissapointed. I used a 3Sixty.2 sound processor to do all the work for me and when I was just tuning in the front speakers with the rears muted this amp rocked. As soon as I unmuted the rear speakers the amp cut out and just got a constant buzz from all the speakers. I am a former installer and have been installing for over 5 years. The amp was installed correctly but just did not perform.

Works great.

This is a good little amp. Mine was rated at 84x4 RMS and fits very easily in tight spaces (a big plus for my install). Gets my T1 6.5s and my M28Bs pretty loud. GETS HOT, but has never cut out. Doesn't give you as much room for adjustment like a normal 4channel would but does the job nicely. I ran mine with a 360.2 to get the sound how I wanted.

Very powerful for such a small amp!

This amp is a great product it is very power, i am pushing 4 Rockford Fosgate power 6.5 speakers and 4 precision power tweeters and 2 precision power loud tweeters with no problems! I would buy another in a heartbeat!

Use in motorcycle Cairo g

I purchased this unit for use in an after market fairing for an HD Roadking to power 4 speakers and I am nothing but impressed with its push power. I will be installing 2 more speakers for the rear and have no doubt there will be no power issue

Great amp

I finally broke down to upgrade the system in my 98 silverado. Got this, 2 T1S652, and then the T1 4x6's. Compared to my old system this thing screams! Not a ton of room for adjustment, but my head unit lets me get it to where i like it. Great price, talk to a rep to get the best deals possible, i saved a few bucks by buying everything together. The only negative is that this little thing gets hotter than a b******, everything else is great. Very easy to hook up. I only had a little knowleddge of car audio prior to this and had no problems.

Great price great sound.

Easy install. I installed it on my Harley. Called the Fosgate tech support they were great every time.

great sound from this little puppy

Have it installed in my venza great power and crisp clear sound. Using infinity speakers teamed up with the fosgate amp

simply amazing

Well worth the money I paid. HUGE POWER from a very small package.
Although, I don't recommend running in 2 channel mode as it clips at higher volume levels until it has a chance to warm up. Operating in 4 channel it provides tight, clean mid bass and piercing highs.

Great customer service

Purchased pnr300x4 great customer service and fast shipping highly recommended

great product

I bought this to replace my old amp and to hide it
powers my alpine r 6.5 speakers. Another great product from Fosgate.

Works great. Very compact

Small in size. Great power. Easy installation. Great for Harley Davidson, it Fits under stock fairing with no problem.

good amp for harley.

so far so good, set filter on hi, only running two channels so far.

Satisfied

As of now I am very satisfied with this amplifier. I placed it in the fairing of my motorcycle(Victory Cross Country) and gained a large amount of crystal clear sound. Definitely worth the money, IMO. Before I used the amp, it was hard to hear or understand the music at 60mph, not though.... I can hear perfect at 90+ with little distortion(wind will always be there). Love the 2 and 4 channel option, but even though its in my fairing wish it was a marine amp just in case.

just right

Works great on my 2007 Cvo ultra..did away with factory amp..hooked to 6 5 1/2 speakers..has plenty of power and super clear sound..used PC hard drive double fan on top as it does get hot.fit inside batwing just fine.make sure to use 30 amp fuse as it needs it all..

Awesome Amp

This little amp packs a lot of punch on my Harley sound system. Tucks away in my saddlebags. Powers my speakers perfectly!!

Small but powerful

Put this on my Motorcycle . Sound is great, clear smooth, no pop when turning on. I’m running 100 watt rms speakers and amp was tested at 89rms -4 and it performed. I can’t turn volume all the way up or my bike starts sounding ghetto with vibration from speakers. It does get warm in my saddle bag but never shut off, so I put a fan on it just to make sure. I was worried about it pulling to many amps, more then my nick could produce but put full load on it to test and it was around 12amps. At a normal level of sound ( one the person a block away can’t hear) around 105 decibel at was at 8 amp. My output was 13 on bike at idle so never going to be an issue. For me anyway!

Nice bass compact sturdy piece

Fit great in my 2 door Jeep Wrangler on the tailgate. Really surprising bass. Finished out my system perfectly! Couldn't be happier.

pbr300x4

great amp for harley custom installs.add a couple RF 6x9's and what ever else you can fit in and it leaves other systems (HARLEY,Sound of chrome junk,etc) IN THE DUST! Installing 2nd one on wifes Deluxe as we speak.

Rockford Fosgate punch Pbr300x4

Great amp purchased it for my 2015 Harley lots of power for a small amp this is my second amp same brand thanks .

Excellent compact amp.

Great small amp. Since it is so small I was able to tuck it behind the stock head unit in my 2013 Tacoma. I added some Alpine speakers and I was able to dramatically improve the sound quality on a budget. This amp is VERY easy to connect, and it is super small. Great performance for the price.

Small package easy installation

Packs a lot of clean power and a simple install. Especially if you use the recommended 10 gauge power wire. So easy to run and hide the positixe and negative wires for a clean look.

Unbeatable

Unbeatable price for great Rockford Fosgate product. Highly recommended using Sonic electronic for this purchase.

Powerful

Amp is powerful. Definately recommend this product. Easy to hook up. Sound is great with Rockford Fosgate speakers...

Compact size

Installed behind glove box in my 2008 charger, sounds better than I expected and really woke up my components.

Very nice amp!

The amp fit great on my 2008 harley davidson ultra classic! The instructions were very clear and made installation quick and easy. The harley wiring hook up also made this an easy hook up. This system sounds great!

Just what I needed!!

Great to hide in small spaces! Very easy to install

Awesome amp.

This is a stick of dynamite. Can't believe how much power this tiny amp will push. Installed with the punch door speakers. Sounds great.
