Really solid little amp packs a big punch
Style: Mono
Size: 300 Watt
Awesome little amp. I bought this because I was not satisfied with the little BOSS amp I bought to power my small Bose subwoofer. The BOSS amp got the job done, but it had soft audible on/off pops, even with the radio off, plus it ran quite warm. This Rockford amp runs cool and quiet. It really packs a punch and it feels rock solid. Granted, the BOSS amp was a lot cheaper but you get what you pay for. If you are looking for a high quality amp in a really small package, this is it.

Small in Stature, Broad in Purpose
Style: Mono
Size: 300 Watt
Just installed this amp a few days ago. I also got the PEQ Equalization remote. I listen to a wide variety of music from classical, to jazz, to rock, covering several decades of changes in recording technology and engineering. The PEQ remote is essential in allowing finger tip adjustments to compensate for decades of differing recording technologies and EQ mixes. This amp does all it claims and does so flawlessly. The boosted rail technology is a very clever engineering feat and gives this amp, which is no larger than a paperback novel, power you would expect from a much larger unit. It can handle both high level and RCA level inputs and it features all of the adjustments you would typically want (gain, band pass) to optimize the bass portion of your audio. I highly highly recommend it! BTW... I have it paired with a single 8" Polk db840 dual voice coil sub. It totally kicks butt!

Product good but a few issues..
Style: Mono
Size: 300 Watt
(First half of review is my 1-star rating, revised in latter half of review) My issue is NOT with the product itself though it has gone bad within the warrantee period. My issue is in dealing with getting the failure addressed. I purchased from Amazon. Amazon was the seller, not a 3rd party thru amazon. Rockford Fosgate will only honor warrantee service to the original seller to whom THEY sold the product and they said that was NOT Amazon. Thru additional research I learned that often Amazon buys from OTHER third parties when they run low on stock. Normally not a problem EXCEPT IF YOU WANT YOU WARRANTEE HONORED!!!. so BEWARE. I've been an Amazon customer for a LONG time and will continue to be, but now I may make some of my larger purchases where I care about the warrantee from other sellers. For example I'm buying some high end camera equipment, I will NOT do that from Amazon, instead using bhphotovideo (very reputable). As for Rockford Fosgate, I'll say that they were very helpful but they just could not honor the warrantee due to how Amazon handled the sale. UPDATED - Soon after (like within an hour) hitting Amazon customer service with my issues again, they offered to replace or refund. I'm revising my rating as a result. I'll repeat that Rockford Fosgate was very helpful and willing to service the unit so they get 5 stars anyway. Units sometimes fail. Just happens. THey handled it nicely, and now can say the same for Amazon. I'm a continuing satisfied customer..

Good amp
Style: Mono
Size: 300 Watt
I bought this to power a Rockford Fosgate R2S-1X10 Prime R2S Single 10-Inch Shallow Loaded Enclosure in a pickup truck. Since there isn't a lot of space, this is the perfect size. It seems to be a perfect match to that sub enclosure. Has plenty of power to run the sub without running the gain high at all. The only knock was the speaker "harness" was backwards vs the installation manual, the black wire was on the positive terminal. Not enough to take a star off. Thanks to my fellow reviewers, I bought the PEQ remote with it. Do not buy this amp without it.

Best Amps Ever
Style: Mono
Size: 300 Watt
I have one of these running my mids and tweets and then this one running my sub. The amps are slightly bigger than a video game cartridge for a super Nintendo and they never cut out. I ran my 75x4 to my mids and tweets in the middle of summer for a road trip and the thing only cut out once. That's amazing considering the temp was about 100 degrees and I was drawing a bunch of power from it. Adding this sub amp was the best hundred bucks you can spend.

Big power in a little package
Style: Mono
Size: 300 Watt
The picture doesn't really show just how small this amp is... if you are limited on space and just need to drive a single 8" or 10" subwoofer this is a great choice. Measure the area you have to work with and compare that to the listed measurements of the amp before you order, but there's not much smaller than this with decent power. I also purchased the optional remote adjustment knob and mounted that near my stereo and it's very helpful when switching different input sources or types of music. As I was adding this to a stock stereo setup in my 2012 VW GTI with no line level outputs I was able to tap into the rear speaker inputs and use those as the input. The amp turns on automatically with the stereo by sensing the speaker input, and the included low pass filter takes the mid and high frequencies out so just the bass comes through. I'm using this to drive a 10" MB Quart RLP 254 in a very small enclosure and couldn't be happier with the performance, it really fills in the lows that are lacking from the stock speakers. I would definitely buy this model again for any limited space subwoofer installation.

Excellent while it lasted
Style: Mono
Size: 300 Watt
I purchased this amp from Amazon Nov 2011. The amp worked excellent and had plenty of power to run my Alpine 8" sub in my truck. Last month my sub stopped working. I checked all wiring and signals at the amp. All were working. Since the warranty had expired on the unit I decided to take it apart and see if I could fix it. I found that one of the components inside had blown up. The unlabeled transistors mounded to the wall of the enclosure had cracked and appeared to blow up. It left debris on the top of the unit. I would replace the component but there's no markings on the item so I can't figure out what to replace it with. I don't listen to music in excess and truely believe after 2 years the amp should still be working. Needless to say I have now replaced the item with another manufacturers amp.
