What is the biggest speaker I can put in place of the "Factory 6.5 subs" on either side of the back seat. Is there any way to put a freeair 8" or something??? If not what 6.5 will put out a nice "thump"...I've already replace all the other 8 speakers with Kenwood stuff...But I don't have any problem in mixing brands!

 

I have seen pics of a 8" woofer put there, but it will require some trimming of the panel back there.

 

Do you have a website or anything showing this?

 

No, actually I don't, it's been quite a while since I've seen it done, like over a year or 2 ago when I saw pics of it.

 

just start hacking!! Just measure off the whole you need for the sub. Most subs usually comes with a template.

 

Will it be deep enough though? Also will 2 free air 8s sound good right there? I don't want a lot of rattle!

 

it all depends on the mounting depth of the sub you are using. There's quite a bit of room behind the speaker so I don't think that will be a problem. Though, You will have to use some sound deading material to stiffen the panel and to quiet any rattles.
