i have an 89 iroc and im puttin in a stereo system i need to know what 4x6's will fit in the dash and what 6x9's will fit in the rear panels... by the way i have a factory bose system so there are no 6x9's in the rear panel i have two rear i think 5.25's in the hatch area ne one have a similar setup ne ways there ARE places to put 6x9's in the rear panels but i was wondering if i needed ne speacial bracket for the 6x9's as well

 

well you basically answered your own question. 4x6's fit in the dash and 6x9's in the sailpanels. Most everything will fit, the Infinity Kappa 4x6 Plates are a real tight squeeze but can be made to fit. Typically the plate speakers in general are a tight squeeze but can be made to work. If money is not too much of a concern then kickpanels are definitely the way to go. Run a search on the Car Audio board and you'll find most of your answers

 

I am running Polk Audio 4x6 and 6x9's in my car. Fit just fine and sound great.

 

memphis 4x6's and pioneer 6x9 i did have lanzar 4x6 but they wouldnt fit at all the magnets were too big and hitting the guage cluster

 

Go to Crutchfield.com and list your car type year and you'll get a whole list of speakers that fit.
