Just have a quick question if i may.
I have a 2003 E46 coupe with the MKIV Nav head unit, standard, no HK stuff.
I have replaced the speakers in the back as they were shot and i'm looking to add a Sub/amp, maybe an active sub as such just for a bit of bass.
Could someone tell me if this is possible with this head unit, how would i connect it all up, would i need certain kit to complete the job?
Any advice much appreciated.
