How to connect amp to factory amp

[nutcase]

Looking for some pointers here... I have a tundra cremax with the JBL factory system. It has a small JBL amp under the seat which powers everything including the stupid little 8" sub in the back. I don't want to upgrade the whole system as it is not bad, I just want more thump in it. I have bought a 12" sub and a kenwood amp that has a 'speaker level in'. Can I splice into the wires that come from the facotry amp and lead to the rear speakers to get signal to the 'speaker level' connection on the amp? Or is there a better way of doing this without changing the HU and all that. Obviously I will be running power wires so won't be relying on the power supply to the small factory amp. Thanks

Find the signal wires before the factory amp, splice them to RCA's and use that to get signal to your amp.

Thanks.... that helps me go the right direction. Do I use a LOC on there or just straight to RCA?
