im looking to upgrade my sound system,Hurdy- u mention the head unit, i was told that head units make a huge difference to the sound (providing they can facilitate the speakers etc) i have a 5 door mk5 and have three speakers in each front door (inc. tweeters) i want to upgrade them, put speakers in the back doors and a sub and amp in a custom box im building for the boot (stealth style) but im unsure over the sizes of the speakers that will fit in each door and shud i change the headunit as im getting different opinions from so called "experts"!!
any help or advice ould be much welcomed
