Giday guys. Just curious regarding the premium sound on the xr6's. Has anyone wired in amps+subs to the factory head units? is it do-able? im guessing it should be, with that in mind... Is there really much difference between the head units power outputs (PREMO/CHEAPO)? - I mean I know yes, thrs a bigger screen + dual climate control, but when it comes down to it, I intend on ripping out the factory speakers and going straight to JB-HIFI A mate of mine works at JB-HIFI and tells me everytime the installers get a BA/BF falcon, they slap they'r head Anyone with they'res decked out, plz, any advice would be appreciated.. Kind regards, J
