Hi all. I'm wanting to upgrade all the speakers in my '98 A3. The front ones had already been upgraded by a previous owner, but they have done it unsucessfully! Result is they have killed the front Infinity speakers as the cones couldnt move enough so have fouled the door trim (hence the cones are fecked now!). I actually have another pair of these Infinitys i have fitted to my old Volvo 850 estate. i think maybee 5.25"? I forget the model number now, but anyways, i digress... What im wanting to do is, install the largest speakers possible with the minimum of fuss (contradiction in terms possibly, lol). I do really like very good quality sounds, but dont wanna strecth the bank balance to far to attain this (another contradiction, lol). I believe my car has an Audi amp somewhere in it (as the rear speakers are much much louder than the fronts (even though the fronts sound garbage!) My car has an Audi sub fitted (none Bose i believe). This is also rubbish! I would ideally like to keep the enclosure, but upgrade the components (i think AndyMac wou could be the man here from what i have read somewhere on here). Incidentally, i have already had an after market Pioneer DEH-5800P fitted (plays MP3 & WMA). Cheers, Pete.
