What subs will fit in the stock sub box and sound good in it.

 

Solobaric l5

JL Audio W6

15 soft dome tweeters

 

Something that is made for a truck box. The dim and mounting depth of the factory box really isn't that big. Also you will probably want to look at a new amp if you are changing out the factor sub. I don't think it has normal sub connections.

I don't personally have the pioneer speaker package so I am not positive about the connections. I do however know the box is tiny from seeing it and from what other people have said about it.

And neither of the subs that 1stbluSS will fit into this box

 

Has anyone actually replace their factory sub with an aftermarket one. If so did it sound that much better???

 

I replaced my factory sub, I used a infinity REF1052W. Sounds Excellent. But, you definantly have to add an aftermarket amp or its not going to sound good. Sometimes using aftermarket components and still using the stock amp make the speakers sound even worse than stock. I already had a new kenwood amp so I just used that amp.
