Small amplifier; big power
Crutchfield customer from Bel Air, MD on 2/7/2021
1971 Plymouth Duster
This is a fantastic, little amplifier. I installed it under the dashboard on the airbox of my 1971 Plymouth Duster. Note: I spent many hours, days, and weeks trying to diagnose a problem, that had such a simple solution. As the volume increased, the sound would cutout at a frequency somewhat proportional to the volume. Root cause of problem: bad ground (25 Ohm resistance). After creating a proper ground (1 Ohm), the sound was perfect. You can see a special COTS ground lug in the photo.
Pros: Superb, compact amplifier.
Cons: None.

Perfect amp for my Harley
Jerry from Batavia, ny on 5/7/2020
2010 Harley-Davidson Electra Glide Ultra
Installed in the fairing of my 2010 Harley Davidson Ultra Classic. I bought this after purchasing the Sony 4 channel mini amp. The Sony didn't have the adjustments needed to get optimal performance. I couldn't hear the music over the bike. This amp is 100% better. I have it powering 4 marine polk speakers. Its crystal clear, i can hear music perfectly with a full face helmet at highway speeds. Thanks to the great customer service from Crutchfield!
Pros: Sound output, marine certified, compact size
Cons:

Great Little Amp!
Paul from COLUMBIA, MO on 1/19/2020
I wanted a small amp to put in Ram truck and it did not disappoint! Easy install with great clean sound. As always, Crutchfield shipped quickly and arrived in great shape. Will always recommend Crutchfield!
Pros: - Small form factor - More than ample power
Cons: - Power and ground wire attachment points not the best for 4 gauge hookup.

Wow
Crutchfield customer from Sacramento, CA on 8/22/2019
Really impressive clean sound from a very small amp. It's driving front components and rear 6.5 full range speakers in my Titan and sounds amazing
Pros: Clean power and small foot print
Cons: Not a fan of the molex connector added a splice point but the Amp is too small to actually put standard 4ch connections on

Sounded great until it didn't
Crutchfield customer from Atlanta, GA on 8/6/2019
Sounded great until it didn't. The amp worked great and waa easy to install. On the third boat day the amp just gave up. Power light al still on and an extremely faint tinny sound coming out from the speakers. Crutchfield waa great; diagnosing the amp as the problem over the phone and sending out a replacement. I'm giving it for our stars in the hopes that the next one lasts and continues to sound great!

Incredible Amp
David from Adrian, MI on 6/14/2019
25th Anniversary Mustang LX 5.0 Convertible Project. I bought my 1990 Mustang convertible when it was only 10 months old and now beginning to restore it. The factory premium sound radio system needed repair but too new for someone willing to repair and make updates. Perhaps someday. Anyway, I purchased a Kenwood cd/receiver along with the KAC- M3004 amp. The amp has plenty of power to hear the music when the top is down through the 6 infinity speakers purchased as well. Though not original to the car, it looks like a 21st century OEM replacement. The sound takes it to a new level far above the factory premium sound system. Thanks Cruchfield, great products and service.
Pros: Clarity. Power.
Cons: None
