Got a sub in mind and need help with my choice of amp.......

 

I'm running my sub off a mono block 1000watt kenwood does the job fine had it for donkeys

 

It's a pioneer sub 500/800 watt can't remember

Where are you mounting the sub mate?

 

In a box I'm making which will be 6.5" deep and 30" wide and 13.5" high.... so basically a thin slim wide box to fit in the booth across the back of the rear seat.
I need space in the boot so can't have anything sticking right out......
