Ok, here is the deal. I just got a new car...already have my box being made for my car....when I notice AFTER the fact that I have no idea if Im going to be able to mount these amps on the back seat BECAUSE it looks like there is nowhere to mount them!
IIRC HiFonics' amps have mounting feet that have to be mounted to the chassis of the amp separately. If you bought the amp new and the feet weren't in the box then there's a problem.
If you bought it used and your seller didn't include them then you need to contact them and find out where they are.
