Replacing factory HU in Mach system
 

I recently bought a '98 Cobra (completely stock) and am looking to put in the head unit from my last car. The HU is an Alpine 9851 w/ the iPod adapter.

Anyways I had my last install done at BestBuy and when I went back to ask about a re-install his explanation got pretty confusing, but basically said that I can't do a HU replacement w/o putting in an all new amp and speakers. However, I read some where else on this forum about an adapter that plugs into the HU and functions properly with the Mach system. Any help, information, and/or links concerning this problem or the adapter would be great. Thanks!

As long as the Mach harness is intact, you can get a adapter to connect your HU to the factory system. Check over at Crutchfield www.crutchfield.com

Yup BBY is not a good source for anything that requires anything over minor thought & research. Best & Metra both make harnesses for your 98. As Larry mentioned this will be easy if the factory harness is still intact.
