I have a 03 v6 sr5 without the jbl. So, I don't have the sub or the trim etc in the back. I've seen the threads on that and how people have upgraded it and I'm jealous of you people with it in there. However the trim panel and sub box are pretty spendy to get the oem parts. I really want something out of the way to keep the cargo as usable as possible. I've seen the custom box that goes over the wheel well but it's pretty huge and i would lose my little storage cubby. Not a huge deal but i think it's too big for my liking. I would just like to add an 8 or a 10 inch sub for more well rounded sound. Nothing window blowing or anything like that. Anyone try fitting a small sub under the passenger seat? I've seen people putting amps under there. I have manual seats so there shouldn't be much stuff under there. Just wondering about some small sub locations and what you guys have tried out there? Look forward to some pics. And I would have posted this in the audio section but our 4th gen nooks and crannies are way different than other gens.
