I had it for a secondary batt, but they do work well for a main car batt. The biggest amp I ever had on it was a 3000d and that was less than 2 weeks @ 2ohms and a couple .5 ohm burps.
Only trades would be towards a Sundown 1500d or 100.4. Cosmetics do not matter to me on the amps. going to invert them under plexy.
Shipping looks to be around $50 to most of the lower 48.
My Allis has a big ass!!
