Hi, I have a 12" Alpine type s in a vented Bassworks box( pretty big ) driven by a Pioneer GM-7100M (RMS Power at 2 Ohms = 360 W x 1 RMS Power at 4 Ohms = 250 W x 1). head unit : pinoeer DEH-P7700MP I'm listening to Punk Rock, Death Metal, Metal, Hard-rock and a little bit of Dr. D.R.E amd Cypress Hill. I find my bass not tight enough and not fast enought to hadle my music preferences. Do you think that two 8" subwoofer in a sealed box will do the job? Should I use two SVC 4" sub to get the 360w at 2 ohms of my amp What brand and model of subs should I go for? Sry for my english
