Is this possible?

you might be able to fit a 8inch tube under the seat but probably have to make it and dont think it would be worth it you could just get a shallow mounted sub(10 or 12inch) and build a box for that and put it under the seat, that would be more worth it and as for the hook up if your doing it yourself. you should just put a aftermarket headunit in cuz it will make it so much easier instead of finding the rear speaker wires in the door and running the LOC off of that unless you go from the dash which would be easy if you just put the aftermarket headunit in. then you just plug your wires into the LOC and hind the wires. if this doesnt make sense i am sure someone else can chime in

rolf, there are single/dual boxes available up to 12" subs for underneath the rear seat.

I forgot about this thread, where are these boxes you speak of?

check pac-audio.com, line converter is too much work and plus it doesnt sound too good.

I have a stock deck and a 7 band eq. It was the best thing I did also gives you a spot to hook your I pod up. I can control all the bands. I also have a 4 channel 800 watts and a zapco 1500.1 modded to run a Jl w7
