O.K. the OEM HK upgraded system blows. :ben: Is it the head unit, speakers, or both? Has anyone just changed the head, left the amps and speakers alone and seen any real improvement? Inquiring minds want to know... :confused:

I changed the HU first... & it made a big difference!

Changing the rest & it so far it seems to make even more difference. :thumbup:

if you are piecing it together, go with HU first!
