Customer Ratings & Reviews

Incredible power that bolts right to the back of your alpine stereo. I paired it with alpine separates and coaxials in the rear. The clean sound is mind boggling and loud..My friends that have paid much more are beyond jealous. Trust me. You will be truly impressed

Great little amp - really powerful and fits behind stereo deck in dash. Recommend getting high quality speakers to really get full benefit of system. Made my new stereo deck sound amazing. Need to make sure that when it is installed that the amp is separately tuned, not just the stereo deck, in order to get max sound quality. Well worth the money - just installed it in both my cars.

This little amp is a huge step up from stock sound system I installed in a 19 f150 xlt I also upgraded the door speakers, this amp really made the difference it increase the volume and sound is clear without any distortion really recommend it to anyone looking for increasing their sound with stock head unit.

Was actually really surprised with the power of this 'little' amp! Bought this to power a set of Alpine door speakers i had just installed in my convertible, and was thinking it would sound better but was surprised at how much power it had and how clean the sound is! Alpine really makes nice audio equipment, would recommend this amplifier! Im running two Alpine 6.5" round speakers with it

The amp fits nicely behind my stereo. Adds the Desired power to my speakers. Stereo sound is crystal clear.

Great size fits in dashboard behind the stereo. Serious power it rocks my kicker component speakers with clear sound

Nice, small & powerful little 4 channel amplifier!

I'm really impressed with this little power pack. It's running a pair of alpine 6x9s and a pair of 6 inch Alpine coaxels perfectly. The power is clean and it's a perfect fit for my system. Can't believe the power this little thing puts out. Glad I made the decision to go with this. I would definitely look into this option to power smaller speakers

Easy to install no power line from battery needed. Does not overheat. Size so small very convenient and its Alpine

I bought this to complement the cd143bt and alpine component speakers. I'd read that the speakers needed more power to sound really good and the car is a convertible so this was perfect. Small, affordable, and not overkill. I thought. It is an amp and it works. Stereo is LOUD. No before and after comparison unfortunately, but the sound is way louder at 3 than 2 on volume adjustment. . Big jump. But it sounds awesome. Really great sound. Clear without strain.

I have this installed on my can-am spyder and it sounds great I can hear my music at highway speeds. Music sounds clear and clean will recommend to others great sound in a small package.

Installed this amp in my new pickup truck recently and it boosted the sound astronomically. Previously I had to turn the radio volume up about 3/4 of the way to be able to hear it with my windows down just half way. Now, I barely have it 1/4 of the way up and the windows down all the way and the sound is loud and clear. Highly recommend to boost the quality of a factory installed radio system.

Adds plenty of power to the door speakers keeps up with the 2 12s and 1200 watts that I put in my car. Easy to wire up and nice that you dont have to run extra power cables if you have a 15A fuse for the radio.

My factory radio claims 40x4 watts. This upgrade more than doubled the volume of my system. It also fits behind my factory radio so there was no need to sacrifice glove box space. Perfect for anyone looking to upgrade their factory system with new speakers. I also have a 300 watt subwoofer that doesnt drown the highs and mids because of this mini amp.

This little unit is amazing with the clarity of sound that it puts out. It can be used with any factory HU, and it is small enough to fit anywhere. It does not require the use of Monster Cables running to the battery, so the installation was fairly simple. Can be used with any aftermarket HU; not necessarily Alpine.

I put this on H-D tourer. It is perfectly suited for under the fairing placement. I can hear tunes at highway speed and at lower volume settings. Easy installation.

I have this in my 2019 taco that I had upgraded the factory speakers. This unit brings the new speakers to life and is still hidable behind the factory deck. Can be hooked up to factory radio 12v wire or ran from battery for more consistent power. Only bad thing is the ground, power and remote wires are all placed on the output side of unit.

Very powerful amp, compact and cost effective. Recommend for great sound quality

This is an incredible mini amplifier, pushes plenty of power , and sounds great with the RF power 61/2 im using it for , easy install and a shout out to Best Buy customer service I had an issue with the wiring and they had me a new replacement in 2 days , great job again Alpine but Best Buy saved you on this review

Kudos to Andy for recommending this amp. 45 watts to each of 4 speakers - Kickers. Huge improvement over stock. Great bang for the buck. Could not be more pleased. Thanks again to staff at Best Buy. John, the installation expert, mounted behind head unit. Never know it was there looking at it. 180 watts total. You’re not likely to be disappointed.
