Adding a extra Amp

Ok so I have the factory L7 amp and using the technic harness for a amp and sub in the truck with technics harness. Can how someone add another amp for the speakers and in floor subs using the another harness or some in conjuction with the L7? I will be shortly replacing all the subs and speakers down the road.

if you have a big budjet and you could get

A mobridge preamp and go to an all aftermarket solution.
doing partial upgrades may be more expensive in the long
run.

Some amps will allow you to pass through. You just daisy chain the amps.

Mobridge is unnecessary.

My JL 500/1 allowed this. I had the 500/1 connected directly to the LOC powering a trunk sub, then a second amp powering my underseats.

The preamp output is the pass through.
