    Awesome amp!! This amplifier works perfect for my two selenium D-250x and 2 selenium super tweeters. Very powerful, I have the knob barely passed minimum and my drivers are SCREAMING, that powerful. I also have a Taramp’s 2500HD pushing 2 Eros 450 rms and I couldn’t be happier with my set up. Can’t go wrong with Taramp’s. Thanks guys!

    The media could not be loaded.  This little amp definitely blew my mind. Sound quality is crisp an clean. It’s compact and saves so much more room than the briefcase amp I had. Absolutely amazed on quality and power this amp pushes. I removed a 1k amp that I had the gains maxed on and placed this and I actually had to bring the gains all the way down. Pushing 4JBL 6.5. And you can’t beat the price. Definitely recommend for a quick sound upgrade.

    I have a set of Pioneer TS-A692F6˝ x 9 in the rear, set of Pioneer 6.5 TS-A652F in the front. User error aside, these pocket sized amps are very clean.I was skeptical at first, getting a foreign product I’ve never heard of. To my surprise it sounds great and price is is another benefit.Customer service/care is off the charts. I can not speak to the longevity of this product, but I’m very pleased end to end.

    Order this morning and received it before 6pm, thanks prime. This amp will literally fit in the palm of your hand, but knowing the reputation of the company, I can’t wait to hear it.**Update**Having some thermal issues with this amp, running (4) 6.5inch components and (4) 3.5inch mids. All speaker are 4 ohms presenting a final impedence at amp of 2ohms. For any regular 4 channel amp, this would not be an issue. But this is Taramps, they’ll tell you it’s a 4 channel but it’s really 3. As for the gains, there currently set to half to match the signal from my American bass eq.

    Pro : In the picture i added, you can see how small these amps are and it gets LOUD. I run mine with one channel bridged and Im amazed at how much power the amplifier puts out. I want another. I have a taramps 800×4 as well and it is double the size but not double the wow factor.con: like all taramps released so far, the knobs are very cheap and tuning the amplifier can be difficult.

    Mounted this in a sound bar I made it running a pair infinity 6.5 mids and tweets on 2 channels and 4 kicker 5 1/4 coax on other 2 channels the crossovers work great using the high pass on the kickers this little amp works great sounds awsome slightly larger than a cell phone and it’s more efficient than a class ab amp also noticed when you engage the low pass switch it dosent only cut the highs but also adds bass .so a sweet versatile little amp. O yea after running 45 min only very slightly warm to the touch all channels 2 ohm unsure of durability just installed it yesterday. Small loud and very clean sounding great job taramps!!!

    I’m running four 6.5” speakers off this and the difference over the built in stereo amp is huge! Sound is very crisp and clear. Great quality for $60. I’ve got the amp gain set at 40% and it’s plenty loud my stereo just above 50% (full volume and your ears would bleed). I ran 8 gauge power cable to it as that’s what I calculated for the run from my battery. I’m wondering if the poor review for this was due to them starving the amp of power by not running thick enough cable.

    I’ll start off by saying, I am an avid audiophile, and while this amp might not have the best of sound quality, that’s easily fixed with a DSP (digital sound processor). Beyond that, the sound quality is actually WELL into the higher end for an amp of this price point and I’m personally just extremely picky, but that shouldn’t ward other potential audiophiles away from this little POWERHOUSE because this amp puts out the numbers it says it does, if not more. I’m using this to power my 6 channel system in my car (although my rear doors are run off the mids channel on my crossovers) My layout is as follows: Infinity Kappa 60.11CS 6.5” – Front doors Infinity Perfect 3.5” Midranges – Rear doors Infinity Kappa 90CSX 6×9 – Rear Deck I am using this amp as a 4 channel running through my crossovers to the speakers, let me just start by saying this thing can push my Kappa’s like it’s nobodies business. My 6×9’s have more bass than my old Rockford HX10 did on a thousand watts, and I’ve yet to have any issues with the amp overheating.I highly recommend this amp to anyone looking to upgrade their system, remember people, sometimes amplification is more important than the speakers chosen, that being said I highly recommend pairing this amp up with the Kappa line of speakers, they shine very well together and will not disappoint.Also, on a side note a GAIN knob and VOLUME knob are NOT the same thing. Make sure you set your gain on your system correctly or you risk burning out your speakers prematurely.

    If you have line level outputs for speakers or a sub. This is an inexpensive option.Class D so it is good for hotter environments.Very small and can fit in more places.Can be bridged for subwoofers.2 ohms 4 ohms.Simple and highly effective.Happy with my purchase and using it to power 1 ten inch sub.
