right now i have an audiobahn a8002t and 2 audiobahn 12 inch subs i think aw1251t or something, but i was thinking about getting one of the '05 type R subs by alpine that is 500watts rms and a Precision Power amp that is 500watts rms i think its the 500.1 mono amp.... anyways would it be worth it to get the change? any louder or is it not worth the money cause i am only 17. also if i got the ppi mono amp i was gonna get a 4 channel ppi amp as well... is that worth it or should i just stick with my audiobahn and get a 4 channel audiobahn amp? thanks
