ive got an 89 RS. I bought infinity 6x9's for the rear, fit fine no problems there.... but the front, THATS another story. Anybody done it before? i cant remember what they are exactly but they are 3-way. Right side fits fine, left hits a vent, i could cut that out, but what do i put in its place??

 

Wait, what size are you using up front?

For trimming and using that duct again, I've seen aluminum cans and duct tape work well. Remember, this is what DUCT TAPE is meant for, so don't call that a hack job

 

yeah i know 350rs, there 4x6,s and infinity does make them! i put sony,s in my dash 140w peak, hooked to a kenwood 250 wat amp. there an ez swap only then to watch for is the two rubber dash spacers, make sure they stay put, i knocked mine off so i tacked them in place with alite super glue. good luck Tom.
