Small size but great sound!

  • Excerpt: To be honest I was skeptical about this one. I was always used to big amps, when I got t his this one I was like is this gonna be enough? But once I installed it, it was pretty awesome. I can't say it is the best out there. But it is good sounding amp. Loud enough to get your ears ringing for while. But not just loud minimal distortion good sound quality. I am using JBL P660C component speakers with it.

Excellent amp at the right price.

  • Excerpt: I have been using this amp for the past week and here is my feedback. 1) It was easy to fit into my i20 because it had auto turn on and Hi input levels. 2) I am running 4 GTO 266 in parallel and 2 GTO 949 and must say that the sound quality is amazing with clean bass. 3) I dont find it necessary to have a separate sub in my car anymore. 4) The EZ gain setting may not be as accurate because the head unit distortion is not accounted for.

Amazing

Michael, Crutchfield
14 December 2012
  • Summary: I Bought this amp almost a year ago, and scene then had no problems or complaints with it. This amp has a bunch of clear punchy power. I had the amp hooked up to some Walmart Pioneer TS-G1643R 61/2"s in the front door but since then have upgraded to Sound Ordnance P-65C Component speakers, the rears are some Walmart Scosche 6x9 speakers that are in Sound Ordinance's Bass Bunker Boxes. The amp's power still continues to amaze me after all this time.
  • Pros: Easy install, looks good, hides wire connections nicely, Amazing power output, Great clear quality sound, Simple gain setup and well built internal cross overs.
  • Cons: -The EZ gain adjuster system is not perfected because it does not check if the deck is distorting, which makes it somewhat usless unless you only turn it up 3/4 volume as suggested by JBL. -Remote turn (via Remote wire) on is delayed

Nothing EZ About This Amp

David, Crutchfield
3 October 2012
  • Summary: I can't say that I would describe this amp as easy to install, unless you are using it with RCA inputs and a remote turn-on wire. First, the adapters for using speaker-level inputs are extremely tedious to attach to the speaker wire. If you strip 1/16" too much then the wire sticks out far enough that it could touch the other wire. 1/16" too little and the screw won't have a good hold on the wire.
  • Pros: Compact size, good power
  • Cons: Auto-on delay, quality of RCA adapters, lack of switched remote lead or speaker-level output.

Great Amp, Well designed

Stubb, Crutchfield
3 October 2012
  • Summary: I think this is a really great piece of equipment. The size is compact and it is built solid. Connections are easy to make. Even though there are only RCA connectors on the side, the amp takes both Hi and Low level inputs and includes bare-wire to RCA adapters. There are two versions of the hi input, one that provides resistance for OEM systems that will shutoff with no speaker detected. It also has a wide range of input sensitivity, from 0.9 to 15V.
  • Pros: Great layout for adjustments Accurate and useful crossover markings Compact size and design Flexible Configuration

Great amp

Jay, Crutchfield
15 March 2012
  • Summary: This amp sounds great, clean and clear. easy hook up, simple set-up with screw-in hold connectors, compared to the other screw in connectors where u can loose the screws, good quality build. Great Idea for the uses of the knob design to tweak the sound, instead of the old school design where you need a mini flat head screw-driver .
  • Pros: clear and clean sound, simple to hook-up connectors. Prices
  • Cons: Automatic turn with RCA may has delay to turn on
