Hey guys i wanna upgrade the front and rear speakers possibly the headunit in my au. just interested to hear what everyone else is using in terms of brands and sizes before i buy. the factory speakers are just crap and are distorting. thanks.

a m8 of mine had a set of alpine type R 6.5' splits in the front of his AU, fitted without a lot of hassle, just used some 6mm MDF as a mounting panel
