1. get the spr-17s for some great midbass... get the 17ref for better sound quality

2. rears.. see how you like the fronts first then maybe upgrade the rears.

3. I run the alpine pdx series bc they are tiny and have power not a big fan of the jl and the sound either.

4. up to you

5. anything is better than stock, its hard to make it worse.

cheers.

Anything is better than stock, ANYTHING!!! lol

My old solara was the best sounding system I ever had. The size of the cabin was great acoustically. Just wanted to add that

Alpine components suck!!!! There in my friends car, they were there highest end they make and they suck. I hate them and he hates them. And it's the SPX model so stay away from them please!!!

If your price range is an issue try boston components. Quality control is the highest in the industry.

The best speakers money can buy.
