One caveat - you'll need to rebalance the fader control at the radio, because the speaker sensitivities of the 130AS and ACX130 drivers are close but different.
From there running a trunk sub can be done one of two ways
A) using Amp+ and a monoblock if you have the 5908 / BA31 / Display+ bundle. you can do fader control, crossover freq and EQ right from the radio. Try it with the factory premium speaker setup first, then go the Focal speaker upgrade route if you want.
Note: An amp bypass is required to use Amp+. I will have a simpler version of the amp bypass harness available for Amp+ users shortly to complete the setup.
B) using the amp bypass harness you can either (1) keep the OEM trunk amp and add a sub or (2) add amp and sub as follows:
- an LC2i+monoblock+sub - the AudioControl LC2i Line Output Converter (LOC) has two precuts and a sub-out
- add an LC1i to the setup above, or use an 1 LC5i. then add a 4 channel amp, monoblock+sub
- LC2i + LC1i or 1 LC5i with a 5 channel and and sub.
This is a single LC2i 'budget' install (the 1st bullet above) using the no-cut amp bypass harness. It has line level front outs, sub out, and speaker level rear outs, 4 channel main amp and monoblock with passive tube sub. Swapping the factory amp and 4 channel in and out for A/B testing was pretty cool. In fact the BA31 audio is so clean the factory amp sounded great with the trunk sub. Oh and don't let anyone tell you that cutting sheet metal is required. it's complete BS.

The biz won't pay the bills yet, so still a hobby right now whether I like it or not.
