Anyone capable of swapping Harman Kardon and Alpine HiFi systems OR upgrading Alpine
 

I have 3 x 1999 75 Connies. Two with Harman Kardon and 1 without. Unfortunately the best car (show condition and only 30k miles) is the one that only has Alpine HiFi.

I'm keen to upgrade that somehow to Harman Kardon either by buying an HK system and paying an expert to install it, OR possibly swapping the system with one of the other cars.

I am not about to attempt this DIY. Anyone on here or anyone know anyone capable of achieving this without breaking my bank account?

Many thanks,
Gavin

There is a "sticky" on this thread (immediately above your post at the moment) about how to retro-fit an entire HK system which will give you some idea of the work involved, and might help with the decision as to what to do.
