A++

Works great. I have it powering my 4 door speakers in my 2001 GMC Yukon. I have Focal 6.5" components and they sound pretty good. Pioneer head unit and sub amp as well. I'm pleased. The 8604 runs cold. I've never even felt it get even a little warm.

powerful little amp

so much power in such a small footprint. This amp is perfect if you have speakers that need power especially mid-range and high frequency tweeters.

Superior 4 channel amp!!!!

Overall excellent price from sonic electronix. First amplifier I have ever owned for my 4 door speakers. Running it 100 watts x 4 at 4 ohms and this amp barely even warms up at high power. Very excellent amp and I can see me using this amp for years. I will be purchasing more from these guys...
Thanks sonic electronix!!!!

Pioneer GM-D8604

This amp is seriously packing for what you pay for it. It is my first digital amp and I am beyond satisfied with it. It has all the bases covered. I have it running my door speakers and it does not disappoint. I would buy this all over again if I had to buy an amp. Sounds great with my Pioneer speakers and head.

I love this little amp

This thing really knows how to put out some power. I have this in my 99 grand prix along with pioneer d series speakers. The highs really sound crisp. It is set up to work as a highs amp so there is no bass but I am going to get some subs hopefully soon.

Great 4 Channel

excellent, compact, beautiful and clear highs. With the right set of full range speakers this amp is up for the challenge. First class D amplifier I've owned and I cant complain.

Fantastic

Pioneer has certainly perfected the technology allowing class d amplifier to play full range with perfect sound quality giving you massive output with minimal power usage. This amp is a must have, I just replace my Fosgate P500-4 with this baby and I am so happy.
