I have used this in a few different systems and have loved it all the way. i basically need something smaller than it now, to fit under the seat of my pickup for my next install. Its in perfect condition, and looks 9.9/10
In the picture, the "zapco" blue cover is missing a screw and is scratched. I am going to take the screws and cover off of another amp that i have, and put them on this one to make this one in perfect shape. If you have any questions, or counter offers, please either PM me or send me an email at [email protected]
