Awesome Product

I recently bought this amp and it is the best in its class how could such little thing produce so much power. I had this amp hook up to one set of JBL GTO938 6x9 and one set of 6x1/2 in rear of JBL GTO628 it moves these very good very nice bass and tweet of them. This amp is very easy to install I have it in a 2008 Toyota Highlander Sport with non JBL System so far the best sound i have ever bought. Being a JBL user, I have never had any problems with them. Would really recommend this amp to anyone who want to step up their sound system in the car would not be disappointed. I GUARANTEED!!!

I have been running all 4 door speakers with this amp for 6 months now and all is well. The sound is great. Also using a JBL GT5-A3001 to power my sub.

Do not BUY!!!

This is my second amp. Both times one side of the amp would stop playing. I only had my amp 30%. My first amp lasted a few days this one lasted a couple months.

little amp with big heart

I'll tell you what, it was a 110 degrees out there, i just did a round trip to long beach, from Valencia, AC works but decided not to use it. When i am alone in my ride, My setting is always at concert levels. Inside the car it was 98 degrees hot i kept saying to myself this amp is going to seize, it never did. Its running one set of 6x8 infinity kappa comps. And a set 6x8 infinity kappa 2 ways. @ a 2 ohm load. This little amp is a champ, I was thinking of going for a bigger amp, thinking "bigger is better". Not anymore This amp handled great. will not trade it for anything else. Good job JBL

Good Amp especially for the money

I have had this amp pushing my Pioneer 6x9's and my 6.5's for about a year 1/2. I have had no problems with the amp.

alright amp

i installed this amp to run 2 6.5'' and a pair of tweeters on 4-ohms. It ran them good but one side of my amp stop playing only after a few days after installation. But stuff like this does happen sometimes. waiting on my replacement amp. I would still recommend this amp even though the complications. I wasn't able to run my amp full load the overload protection would kick in.

Nice Basic Amp

This is a good basic amp. I have a regular cab truck, so I only need to power 3 speakers - 2 6.5" Eclipse PointSource speakers in the doors, and 1 MTX Thunderform (93-97 Ranger Model) with a 10" MTX Subwoofer.

I used a 0.5F industrial capacitor (24V) inline with 4GA power cable. Speaker Wires are generic 10ga stuff. The RCA cable I used is both shielded and twisted-pair.

Overall sound is a bit harsh / tinny compared to what I used to use (a Rockford Fosgate Punch Power 4-ch from 1999), but the sound is good and the price was very right.
