I have 03 TB, has boss factory speakers, so I'm assuming it has the amp. I have aftermarket h/u and want to use it with my aftermarket amp to power my sub. Should I use factory amp for factory speakers, or can use another aftermarket amp to power the factory speakers until I get new ones. Can anyone guide me thru this? I have read entire post/threads and see no wiring diagrams or schematics for 03 tb ltz. Please help. I'm lost.

Also, do I need the chime, rap, swc interface to hook all this up and keep all factory options, chime,acc, rap, etc working?

Can I eliminate factory amp all together and just install new head unit, interface, steering wheel controls, my new speakers in all doors run by one amp, and my sub run fromthe other amp, with a capacitor?
I don't really know where to start, and if I can eliminate factory amp without losing any necessary functions.
