Hi, Been thinking about what to do and how it could be done. Fronts are easy sorted with a set of splits but then what to do about the bass? I like bass but then again do not want to drive around and feel like someone is kicking me in the back constantly. I have not seen this done but I think it is very possible and has a few benefits for me. I like the space behind the ute seats as I often use it to put things behind there and out of the way so not having this space would be unpractical to some extent. So I thought rather then run a single 12" or 10" behind one of the seats, why not run an 8" either side in the same location as the factory rear speakers. Another issue I have is that my seat is always moved back all the way, so the space behind the seats is not that great anyway, would struggle to build an enclosure with a volume of 1cf. There is heaps of room where the factory 5x7's live, even for an enclosure to be built. Looking at something like the JBL GTO804 8", they should work very well in a small sealed enclosure? Any feedback from audio buffs is appreciated. Cheers.
