I'm going to take a trip next week hopefully & have a look. If it comes to it I guess unboxing & getting what I can in the boot & the sub in the passenger seat isn't so bad as long as it is all well protected.
Had to do this with the soundware xs and av reciever i bought in store in my s2k, the sub was a dog to fit on the passengers seat on lap of gf for 30 miles!
, just finished setting up the PC, the Onkyo kit is easy to use and quite understated, playing MW3 is awesome, where I used to gain an advantage through my headphones you now get it through the 5.1.
