Great Sound Great Price

The following review is for a previous version (e4300).

I installed this amplifier in a customer's car to run a pair of JL Components and a pair of Infinity Kappa 6x9s. To this date it has been the best sounding installation that I have done for any of my customers. For the quality of this amp the price is excellent. I would recommend this amp to anyone.

Great amplifier.

The following review is for a previous version (e4300).

I have been using this amplifier for a few years now, and have never been disappointed by it. It powers two MTX 6" mid and high range speakers very clearly and a 10" Sony Xplod subwoofer with great power and clarity; as a matter of fact I am in need of a subwoofer upgrade because the subwoofer only last around 4-6 months of continuous pounding before it dies. For only having an RMS rating of 300 watts, this amp delivers more than it boasts. I recommend this to anyone who wants a simple yet loud and clear sound system.

Decent amp, very good for the money

It certainly isn't the loudest amp, but it does the job and sounds nice and clear. If your car is quiet, this will probably be enough to drive 4 speakers just fine. If you have a loud car (ie, loud exhaust), this may not be enough.

Great amp

This is a great amp. Crystal clear! Not the loudest amp. Nor does it have huge bass. But it still makes my infinity references kick pretty hard. I'm running a 2 ohm system and for this amp, that is definitely the way to go.
