Subwoofer / Speaker Question

[Hauling Bikes]

I have an 03 T4R with 10 speaker JBL system. I'd like to beef up the subwoofer and replace the rear speakers (all the way in the cargo area, not the back seat). What size speakers are back there and can anyone recommend a good replacement for them? I'm guessing they're pretty small but don't know the size.

As for the subwoofer, I'd like to just swap that out and replace it with something but still keep the stock look to everything. Because of bikes and stuff I carry, space is a bit of an issue for me. Any suggestions on how to do that and what subwoofer to get?

I already have an Eclipse amp that I'll be using so I'm not so concerned about that end of things.

Thanks a lot.

If you go on www.crutchfield.com you can look up all the speaker sizes.
