Great ideas chaps - active sub camouflaged behind the seats is a good one, as is velcroing remote ahead of gear-know - really should have thought of that myself!
The latter means that I can treat myself to a decent Alpine head unit...preferably one of the newer ipod specific ones.
Need to find a small active sub (if removable, even better) - and then simply upgrade the current 2 ways to something better, with a small amp in the boot to run them (not worried about sound stage etc, so no fitting speakers in the front...)
Time to go shopping!
John - I hear you: I have four of them slung out the back: but sometimes, need to drive home listening to Dire Straits, erm, I mean something really cool.
Oops.
