If you are like me and dig the factory head units interface with the dash computer, here is some info that I found out about changing speakers.
In the dash : (2) tweeters (tech didnt know what size) probably 1"
In the front doors : (2) 6 1/2"
In the rear side panels : (2) 6 1/2"
In the rear deck: (2) 6 3/4" woofers
All of these speakers can be swapped out with better models according to www.crutchfield.com . They also have the factory speaker wire adapters that they throw in for free. Crutchfield is an excellent, painless company to deal with. I did up my Syclone and bought my home theatre from them and their service/support is second to none. I just talked to a support tech at 9:00pm on a Sat night and he pulled up drawings of my goat in seconds... Find that elsewhere.
I am also trying to find info on the external amp and its interchangability.
Anyone that can expand on this or has modded their factory unit, I'd be grateful for the info.
