I'm looking to upgrade my speakers in the next week or so. Looking for diameters for fronts and rears, not too bothered about tweeters.

Any info would be greatly appreciated.

Hi I’ve just had a pair of Alpine s-s65 speakers fitted in the front doors I also had the doors dynamat’d as well and it’s made a massive difference quality wise well worth doing in my view the original speakers were appalling they went in the bin,didn’t have rears fitted as ours only has front speakers I’m going to have an underseat subwoofer fitted at some stage just for a bit of bass cheers Paul n Tash
