What I got is the Panasonic HU and the 7" screen inplace on the Blose system. Well I about to buy some Alpine Type R Components (Unless someone knows of any better ones around $140) and Alpine Type R Coaxiles. I just need to know for the 97 Bose system do I need to get regular 6.5 speakers or 6.5 oversized speakers or 6.75 speakers. And today I just bought the HU installation kit from Crutchfield.com. For the amp I'm going to use a PG 600.2amp running it to a 12" Alpine Type R Sub in a ported box. And i'm going to use 4 guage Streetwires Amp Kit. As for my PS2 what kind of Inverter should I get 300W or 160W? And where do I hardwire the inverter in the trunk? Please help before I rip apart my whole system and find out that i need 1 more stupid thing to run the whole thing. Thanks People.
