 Mach460 preouts
Has anyone ever identified the wires in a factory Mach460 system that carry the signal from the head to the amp?
Provided voltage & impedance were favorable, it seems to me that if these were identified it would be relatively easy to replace the factory amps w/aftermarket ones using the factory wiring and head unit. All you'd have to do once you found the correct leads is fit an RCA jack onto the end.
I would think a turn-on lead would be easy to find within the factory wiring as well.
You could use the factory speaker wires as well, once identified....just buy components & mount the crossover in the trunk....factory tweet wires connect to crossover tweet output, follow suit w/factory woofer wires.
Of course, you'd still want to run power from the battery, as with any amp installation. |
