I would like some info on the speaker size before I take off the door panels. I would also like to know if there is a specific bypass when installing a custom system. any recomendations are welcome. Thanks

There are a few sites with recomended replacements. Crutchfields.com what fits my car?

Check with crutchfield (I belive they're at crutchfield.com). Semi-local place to me thats been in biz since the 70's. You can put in a specific make, model, year and they'll tell you size(s) for speakers, receivers, etc etc and wwhether you'd need to do any mods to fit one model/size in, or whether its a stock fit. Great place to do bus. with too. Have used them for years. Good luck.
