We got a new car to add to the 1g and 2g... it's a 2001 Celica. First thing on the list is system and I'm thinking about an Eclipse 15". How is the overall system sound quality compared to that of a couple 10" subs. I'm used to dealing with 10s & 12s but we're going 15 for this one. I believe front & rear are 6-1/2" pods. What do you think? Hey Matt - do you have a link for the Celica's wiring diagram? Thanks... late
