Factory AMP and aftermarket amp.

[digital_cowboy]

Hello,
I have finished up adding a c33 tapedeck to the ethirty. It currently is running via the stock harness back to the factory amp in the trunk and I am surprisingly quite happy with it. However, I think it needs a little more low end "fill".
My question is:
Can I splice into the preamp wires and run a split to a second amp? Maybe a single or dual channel to feel a small sub?
TIA,
will

Yes, you can.

You will be beating your head against a wall, but you can.
