I'm starting to look into some sterio equipment, because frankly, I want to have some good sounding stuff in my car. Here is what Im looking at:

Headunit: Pioneer Premier DEH-P580MP
Dash Speakers: Pioneer TS-A4670R
Sail Panel Speakers: Pioneer Premier TS-A940P

I can get all this for $339.00 @ www.onlinecarstereo.com with free shipping. What are your guys opinions on this setup?

I know the Dash Speakers will fit because they are 1 3/4in tall, but I have a snugg fit with my Jensen 6x9's that are in there now with the tweeters hanging off them, will I have even more trouble with these?

Anyone make some decent looking convertion plates (DIN to fit in DIN .5) like they do for the 4th gen?

 

The height isn't the problem with dash speakers, it's the magnet width. They may or may not fit without modifications in your car. You can't really be sure until you try. But, it's not a major issue to make them fit. Check out the tech article in the tech section. It gives you a step-by-step for installing 4x6s with oversized magnets into a firebird.
