upgrading 1998 BOSE Concert speakers

[manikm]

are the front door ones 4 inches and the rears on parcel shelf 6.5?

If so, will any aftermarket speakers fit straight in>

Does anyone know the power of the AUDI mini amp attached to rear left speaker!?

Ta.

hi there, just upgraded my what i believe original sony system at least the HU and 10dics changer, before the front speakers where intermittant and the overall sound quality was poor, though after i fitted my own head unit it sounds superb with most people asking if i have a sub in the boot!
