I replaced the factory head unit with a IVA-D310 Alpine 7" Touch Screen Flip Out.........and now I'm on to the speakers......I have a 1998 4Door S-10 Blazer and I need to know the sizes of the Dash Speakers, Front Door Speakers, Rear Door Speakers and any other speakers in the truck if there is any..... Thanks alot guys!

 

doors are 6 1/2's. probably only a 1 inch tweet in the dash. a 4x6 plate will fit, sometimes with little or no trimming

 

In the dash you can fit certain 4x6" speakers. The main thing is mountingdepth as the magnet could hit the air vent tubing. I got a pair of eclipse speakers that worked. What I would do is buy these speakers locally and ask if you can test fit them. This is what I did, then you can figure out if they will fit and if you will be able to mount them normally or creatively. Definately check both sides as the mounting depth and things you will run into varies from side to side. Otherwise same thing goes for mounting depth on the door speakers, but you will definately be able to fit 6.5" speakers in the doors.

 

awesome guys......I plan on replacing all the speakers with Alpine type-S 2-way speakers!

 

alpine type s speakers are awesome i have 5x7's in the rear of mine and they are sweet and i have blaupunkt 4x6's in the dash the doors i still have factory plus the deck but i tuned it together and its loud and clear with a nice helping of bass not sub bass but just enough to sound good turned up im going to be hooking up a head unit and 2 rockford fosgate 12" hx2's soon along with everything else im doing with my blaze at moment lol.
