Great Value

I bought this amp as a temporary replacement for one that I paid hundreds of dollars for... the sound quality is just as good and believe it or not this one is louder with the gain only being at maybe 30%. Its now considered my permanent amp until i have a reason to replace it! ive had it for 9months so far no problems.

The only down side it that i hate the type of leads it has to connect power and ground with a passion, they are too small (will fit it 8 gauge) ... but for less than $70 you cant beat it.

awesome

This product is amazin, very cheap for the quality. I have been using this amp for about 4 years now and have had no problems. Also the terminals are a perfect size because it only requires 8 gauge wiring.

Better than expected

I have a friend I’m installing upgrades to stock sound system. He wanted to do it on a tight budget. I chose the autotek amp mainly on good treviews. I was surprised by the sound quality. I used an and dd1 and my meter setting everything up. Using a bunch of stuff laying around in the shop. The amp was putting out 45 watt rms at 4 ohm with no problem. The mb quart mid bass and 6.5 came to life. The sounds are crisp and clear. He has an old jvc head unit that starts to distort at 45 volume. So I adjusted to that. So far he has said he has no need to turn it up that loud. Only question that remains now is how long will it last. Hopefully the quality feel and sound is a good indicator that it will last for years. The amp is large and heavy for its rms output so hopefully that is another sign of quality. Overall he and I are pleased with the purchase.

Decent amp for the price. Running 2 channels at 2ohm a piece on my highs, and have the other 2 bridged at 4 ohm running 2 10s under my seat in my truck. Pretty clean and decently loud. Make sure u keep the bottom elevated because it does get hot at full tilt. I can beat on it pretty hard for about 30 min before it shuts off from clipping the hell out of it

Great amp for Sub or full range

I have had this lil gem for a month or so... 2 channels powering 4-6x9 three ways & 2 channels bridged powering a lil 8 inch subwoofer... I smoked the 8, it was rated for 300 RMS... I believe the spec sheet now, cuz at 25% gain it was smoked in 45 minutes. The voice coil melted the cone & adhesive... Great amp, I am now gonna put a Skar 8 in the smoked ones place.

Nice quality amp

I really like this amp. I have always been a fan of Autotek and so far I still am. I have this on a pair of JBL 6x9 and 6" components and they sound great.

Worth the money

I am using this Amp to push 3 pairs of 6 x 8 Kicker speakers in my conversion van. I am very satisfied with the sound and power this amp provide. Along with the Belva 10 inch sub combo it sounds very good overall.

Good price

This product was ok, had a problem hooking it up simply because the rca's were just one channel. Not two, I had to go buy 'y' splitters so I could get the signle to all the speakers I wanted to run.
