HI Everyone...Another question on upgrading my M/C stereo...Im looking at just add a 4 channel amp to power my infinity kappa's and keep the factory head unit. Dose anyone know the correct adaptor i need? Looking online ive come up with 2,both by PAC...The C2A-GM24 and the AOEM-GM24. I that the upgraded system with the factory amp in the trunk,not the bose system...Also,is there an adaptor that i can plug into the factory speaker harness from the new amp? I would rather not go cutting wires. Thank you for all your help so far.....Mike

 

If you're keeping the factory head unit you won't need the GM24 harness, that's only needed if you're replacing the factory head unit. All you're gonna need is a high to low converter and you're gonna have to do the amp bypass as well.

 

when i ran my amp i never did the bypass.

it sounded good,

BUT from wha ti have heaerd is the by pass makes the sound better.
But agian i did mine with out it so if you dont want to you do not have to do it.

But i would say it is to your advantage to do so
