I'm in the process of replacing my audio system in my turbo S with monsoon System. I have jbl gto608c components along with a jbl 1014 10" sub and box in the trunk... I'm trying to get rid of my sub all together and get back my trunk space so I've found several 6.5-6.75 subs but I got a kicker shallow mount. My idea is to replace the stock speakers with better ones and replace in the subs with real subwoofers just 6.75-6.5 in size will this give me the same effect as having a 10" sub in the rear...? If not 2 "door subs" how bout 4 6.75-6.5 subwoofers?
