I have the A6001 (black one), never installed it but these amps are very nice and very powerfull. That amp is underrated puts out 723 (or more, read different stuff all around).
I would spend a few extra bucks on that amp. But that just me //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
Ive talked to some people about that. Some have paid that price on ebay and got the warrenty. But I dont think they will take it becuase you need a recipt and they will know about how cheap you got it. But do you need warrenty? Ive never had to use my warrenty on anything I own (lots of car and home audio stuff) *crosses fingers*. If you can spend another $30-40 then you can get one with a warrenty...
you know now that you said that one by one everything is going to break down and fail, hehe //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
