Great for the price

I have this amp running my door 6.5 component's and rear 6.5 component's and they get super loud! It gets a little warm but has never gotten hot, even after long road trips. Great amp for the price.

Really good amp!

Very strong amp for mids and highs. Also fairly decent for lows as well.

GREAT amp for the money

This is a great amp for the money...right now im having it push 4 polk audio db 5251 and they are screaming when i turn it up...although the amp does get a bit warm it never got hot...only problem that i had was that i couldnt fit my 4 gauge Knukonceptz Kolossus wires and had to trim it a bit but other than that great amp for the money.

Great

amp review

I just installed it today. Have to install the
Radio and rca plugs on Friday. Then I will see how it plays. But it's a solid piece of equipment
I would recommend everyone to buy it. Auto Tech.has been out for years.

Absolutely amazing power, features, and quality for money!

Wow! Simply amazing! With this 4 channel, 2 ohm stable, bridgeable amp, you can run 4 channels at 200 watts RMS at 2 ohms. So you can run four 2 ohm subs, or two 4 ohm dvc subs at 200 + 200 x 2, or sub(s) on 2 channels, and your mids and highs on the other 2 channels at 200 watts RMS x 2 for the sub(s), and 200 watts RMS x 2 for the mids and highs, with low, and high pass crossovers for each respectively in your car with just a $25 4 gauge wiring kit. It's a real 750-800 watt RMS watt amplifier, with a 9 db bass boost, twin adj. high and low pass crossovers, two 30 amp fuses, which is more than the 2000 watt max Autotek amplifier has. You can't make more power than the fuse protection will allow. So I feel they were honest about it's RMS power, which is the only numbers you should be concerned about when purchasing an amplifier. I tested it and the numbers were very close to it's advertised RMS power. Even though it says 1500 watts max, everyone should know that most amp companies will double the RMS output for their advertised max output. At least it really made at least if not more than it's advertised RMS power, a lot of less expensive amps don't even do that. So for an honest 750-800 watts, that can be used in so many different configurations, and being a very nice looking, great quality amp, for $67.50 for each of the 2 I bought, with free shipping, was an absolutely incredible deal. 2 bridged 4 ohm channels makes a rediculous amount of power for $67! I couldn't be happier about the purchase! It's too much power for the two 300 watt RMS 12" subs I have now that I thought would be able to handle the power from past experience with the subs. So it looks like I'll be buying 2 more of the same subs, or just 2 louder, better subs, that have higher power handling capabilities, which should be about the same amount of bass if not more than the 4 lower priced subs. Either way you can't go wrong with this amp. Even at $75, without the extra 10% off I got during the Grads sale (thank you Sonic Electronix) it's still an amazing deal. I have one running in my home off of a $14 ebay Dell server power supply off of a 110V oulet getting 67.5 amps at 12 volts. It works amazing powering 4 quality 12" subs, two car audio subs, and 2 low frequency, long throw home audio subs, and can run all day long like that if I wanted to. It's way overkill for a home audio surround, but too much is just right! A true 800 watts for $80 total in my home audio setup is sick! Thanks again Sonic Electronix!

Great Value

Got 2 of these amps 1 for my front/rear speakers & 1 for my sub, the both run great and sound great. Was a bit worried buying these because the price was so low, but they are great power house amps.

Awesome value

Using it to run infinity reference 6.5 separates in the front and 6.5 coaxials in rear. Plenty of power and sounds great , with 50 amp fuse I'd say about 500 watts clean. For the price cant be beat.

Best Bang For Your Buck

Wanted to upgrade from my cheap Sony xplode amp (600w 4 ch)
I mainly picked it off the sleek metal design and blue lights to go perfect with my black interior with blue piping/stitching and also cause of the rating. I already knew it would NOT put what it rated (not cea-2006 compliant) but by no mean is weak. Definitely outpreformed my Sony amp. Ran 6*9(mtx terminators) in the back they pounded hard along with the second side bridge to drive tweeters (mtx roadthunder 2").
Then ran 4 speakers (6*9/6.5" mtx terminators) off 2 channels with the tweeters.
Then I got the mtx 12" t812-22 which is receiving about half RMS and is breaking in and pounding my heavy chevy 77 caprice .
Got it in a pre fabbed box (and soon to be manufacturers rec. box) and it slams it pretty good makes the cd remote wiggle around the dash.
The sub is a power hog and the amp goes toe to toe. It still put out decent power at higher volumes but around "tolerable" volume the bass is awesome. I pound the screws off this amp and its a champ.
It gets lukewarm at best and hasn't skipped a beat. Very versatile and make good clean power all day!
Gains are easy to adjust with a flat head but the black coating scratches easy.
Wire terminals are very secure and make wiring look clean.
I would buy this in a heartbeat buy now because the stopped making these and the new ones from maxxsonics look a lil funky to me.
Great buy all around!!

Amazing product

This amplifier completely made my new conponent speakers sound different. Now there so clear, every little detail of the song can be heard, and not to mention how loud it can make your speakers go with no distortion what's so ever. Highly recommended, very affordable product, and you will get your money's worth.

good buy

I bought this amp in march of 2011 and its a good amp i have it running 4 6 1/2 kicker sounds great no problems at all.....

Can't beat it for the money

I have this amp pushing 4 12" American bass xd's. Each sub running at 2ohms each having their own channel. Terminals are great, very adjustable setting filters, all around great amp for $80 oh and the blue lights are pretty cool too. Rattles windows a block away!

Great Amp!!!

I bought this amp not knowing much about autotek except for the reviews on this site. i am very impressed with it 100% it gives my kicker the greatest bass. and the kenwood 6'5 in the front door sounds unbelievable this amp is a awesome amp indeed!

Great Amp!

This is a great amp! I have two rockford fosgate punch 6x9's, 2 RF punch 6.5's and two pairs of RF punch tweeters hooked up to this amp. I've had it for about 6 months and haven't had any problems with it...I drive 5 hours to Juarez, Mex. every 2 weeks and I bump my music all the way there and doesn't get hot! I've given this amp a beating and still works great!

Great amp, runs cool

I bought this amp six months ago and love it. It runs great, doesn't use to much power, never cuts out and very clean power. I would definitely recommend to buy and i have bought two more.

Runs cooler than most

Hi, I bought this to replace my New Polk Audio 660 amp. This is a follow up on another review. I have been using it for 2 weeks now pushing my 2-way infinity kappas. This amp runs much cooler than my previous amp, as it remains warm were the other would be burning hot. Also running cooler than my two others pushing the subs. I am also getting the Zeus i80 soon and will be comparing at a later date.
But this amp mids and highs sounds very smooth and using "line-level" it has ZERO noise, quieter than all my previous ones. It also has bigger terminals and better crosover controls than the Polk unit I returned.

Great amp

I bought this 4-channel amp to replace my Lanzar 2-channel amp. I am powering both my 6x9s and my boston acoutic sub. This amp is amazing! It has a great design and wonderful amount of power. You cannot get a better amp for this price.

Auto tek 1550.4

Excellent has worked great so far still goin great amp

Update after Zeus i80 comparison.

Okay I have compared it to the zeusi80, and wrote a review over there. End result is I returned the Zeus, and kept this one. It simply performed better under low power conditions, It didn't have the brighter sweetness of the Zeus, but had smoother richer sound-stage. I also gave it a beating by switching it to the back speakers, so it was running four 12" Hifonic woofers at 2ohms each... And it didn't break a sweat, just got louder!
