Hello,
I am selling a LIKE NEW Xtant A600/1 Sub Amplifier. Xtant is considered one of the premier brands in the business and this amp does not disappoint. I bought this item from Hi Fi Buys almost 2 years ago and had it in my Acura RSX for about 6 months and since then it has been sitting in my closet. This amp is perfect condition outside and in. I paid almost $650 at the time for this and now would like to sell for $400 SHIPPED. Please PM me with offers or questions. Thanks,
-Antonio
