Yep.

Find the stock amp, and unplug it. Then, find the speaker outputs, and run wires from the back of the head unit to the appropriate wires from the amp. Then, the factory wires will take the power to the speakers.

-or-

Just run all new speaker wires.

Or, find the "input" wires at the stock amp that come from the head unit, and connect them directly to the output wires that go to the respective speakers.

Note that there will be separate outputs at the amp for the dash tweeters and door speakers. If you want to keep the tweeters you'll need to put a passive crossover inline.

The stock Infinity amps are pretty ghey, and don't like to be interfaced with. It's better to just bypass them completely.

I wasn't clear; that was a method for bypassing it. The Infinity amp uses high-level inputs so there are two input wires coming from the head unit for each speaker; you can bypass the amp by just connecting the inputs directly to the outputs.

On the other hand, I've integrated hundreds of these for people who just want to keep the stock speakers. They're the easiest type of factory amplified system to integrate; all you have to do is connect the amp turn-on wire.
