i want to put a good system in i want to keep the speakers in the dash but the back ones whats a good speaker with a lot of bass and also is there any subs i can put in if theres no good speakers with alot of bass

 

Well subs and bass are the key works there. And here is why.

JL makes special subs 8" or 7" would be nice but with only 4x6 plate fronts I don't thing it would sound good. Everyone would agree that a nice midbass driver.

I am doing to go with a Dynaudio 3 way set like 5.25,4,1 in the front w/kickpanels and JL 7" subs rear. Also the amp is SO SO important so I will run a ALPINE digital. They are very powerfull but very small and do not get hot so I will mount it behind the rear cargo lock box. No one will ever know it was there. Cost for this is retail 3k but you could always buy older alpine X and a ebay Alpine digital and be around $700.

 

BTW, their is no 86 RS.

You may want to think about a custom sub box in the back if you want bass.
