Best in pairs
I have this amp and the ZXi6006 in my GTi. Very nice amp. They both look great together! It powers my speakers great, not much you can ask for out of it. Nice and durable, as well. I love the blue lights when showing the system off to people.

Very Pleasing
I own this amp. And had it hooked up to a small 10 inch JL Audio Subwoofer. This amp pushed enough power to make my car rattle.. I recommend this amp to anyone who is interested.
