I have a 2007 Civic EX coupe with a stock 8" driver in the rear deck. I am running a PPI 900.4 on my front stage and another on my rear being the stock 6.5 and stock 8" driver. The amp barely makes noise with the PPI as most have noted when not using the stock amp, so I am looking to at least run a new 8" free air sub in the rear deck. However the trunk bars keep this sub very shallow.
My Amp is rated 14.4V 4 Ohm 145 x 4
14.4V 2Ohm 225 x 4
14.4 4 Ohm Bridged 450 X 2
What sub would I use on the Back channel of this amp?
