Awesome Amp

I've had this system in place powering 4 60 watt speakers running at 50rms each and I've never had a problem with it. It runs a little warm to the touch after a long drive with loud music, but that's to be expected. All in all I've never noticed any negatives about this amp in the last 6 months, and expect that it will continue to preform greatly.

Super Amplifier

This is by far the best AMP I have ever purchased. It is quiet,stays cool and no distortion. Any one who about to upgrade your audio system should really consider this AMP. That's why I bought 3 of them. Sonic Electronix has very fair prices and fast shipping.

Nice Quality

I have had this in my Dodge Caravan for about six months. Install was simple with the power cable kit (sold seperately.) Haven't had any trouble at all sounds great! I actually enjoy driving to work now.

Pioneer GM-6400F

Awesome amp! Nice power. Years back i owned a pioneer AD360 amp. It had a lot of kick and the GM-6400F is the same. Just make sure that it is connected to a 4 channel car stereo otherwire you loose sound.

Good starting amp for sure

Good sound quality for this price. Nice design and features for price also. Really can take the heat too. Ran it hard in one hundred degree weather. It was ready to start melting my car before it turned off. Finally did but let it cool for a minute and it was right back to working perfect. Great budget amp to beat up.

Great Amp for the price.

First off, great price on a CE 2006 compliant amp. It works perfect to power my Focal Comp's and rear 2 ways.

Rugged design, and has some wieght to it.

Great amp for an even better price!

Great amp. It's heavy, which means it's built well. It was easy to install. Never gets hot. Maybe just warm during a road trip. It made my speakers sound so amazing. The subtleties are just that much more apparent now. Get it. You won't regret it.

GM-6400F in 4 channel mode.

I use this amp in my 93 4Runner. I have component speakers both front and rear. For the power rating of this amp as a 4 channel it provides more than enough to fill my ride with every note amazingly. I use the 5400T in bridged mode to power a single JL Audio 10". The two amps combined makes for an incredible entry to mid class combo. For the price can't be beat.

Completely satisfied

I had this installed under the passenger seat of my 04 F250 in conjunction with the AVH 4300 DVD player and 4 Pioneer TS-D6802R speakers. The sound is awesome. I did add 2 Pioneer shallow mount subwoofers and another Pioneer amp for the back. The subs really completed my sound.

This is a really nice amplifier especially for the price. Small in size, light weight, easy to work with, easy to tune. I have this amp powering two sets of 6.5 component speaker systems and it pushes them hard. Hard but clean. It offers a couple of great protection features as well, so IT wont let you blow your stuff. Overall awesome value. I would recommend this amp to anyone wanting to upgrade their sound system.
