Pioneer GM-A6604 Reviews

Consumer review (newegg.com)

Great performance!

While not a top-of-the-line amplifier to feed a mega-dollar system, it performs just fine in providing a much better listening experience over the OEM equipment.

Good power out. Very "smooth" sound. Lots of adjustability for various inputs & outputs. Generates very little heat. Reasonable price. Overall an excellent amplifier for upgrading a stock truck stereo system.

None yet. Performance has been flawless and I have zero complaints.

I have HPF tuned to 63Hz before it ever reaches the amplifier, so I cannot attest to the high and low-pass features of this amp as I am not using them. I am not pushing gain higher than matched 4v pre-outs. I prefer sound quality over loudness/clipping...

The amp works well. I have it tuned perfectly for my 4v pre-outs and it works well powering two 6x9's for now. I intend to finish hooking up 6.5's tonight to use the full four channels. The 6x9's are very powerful and clean with the deck at 3/4...

The packaging was dismal. There was some bubble-wrap on all but one side. The amp was in its original box, though there was no instruction manual or other accessories. This makes me think the item was possibly open-box or tampered with previously....
