Well i have a 1991 reg cab s10 and i really want to upgrade my system. My current system sounds like crap and i wanna change it out. I currently have 2 10" bazooka subs and a 600 watt mono amp pushing them. They are ok but i want more. I can have a max of 4 13/16's mounthing depth and around .66 air space for each sub. Also i have 2 mono amps 600 watts so if i can i would wanna get a DVC sub so i can hook up both amps and push a lot of watts outta my little cab, but only for subs that can handle it. I would like to go for 10's but if i cant 8's would b ok. Any suggestions? Thanks
