[kornflake7]

anyone know if the 400a cars are pre-wired for the sub?

I checked it isn't unfortunately

And if it was, you would be limited to using the stock sub and amp, since the signals from these wires are not compatible with any aftermarket amp.

Are the signals encrypted?

Off topic, stock sub wiring- white stripe on blue/red pair negative or positive?

It's some sort of blended signal that is only compatible with the factory amp.
The feed is 2 wires with a metallic shield wrapped around it. I have no idea where this signal originates, and it seems to be a full signal, not low passed.

As far as the factory sub wiring:
Positive = solid
Negative = stripe.

Yes, polyfill in the box, and here is the bass knob:

Nice! I hope to get mine going soon.

Just tested out my factory Shaker sub with my aftermarket amp and I have to say, I'm impressed! Sounds better than my aftermarket sub! Now I have a question... what do I set the gain and frequency to for the Shaker sub?

I'd love to help but my amp came with a setup CD and some nice setup instructions.
Did you.check the website of your amp for a setup guide?

I thought you set the frequency according to the sub requirements. Is that not correct?
I can't remember if the Shaker sub specs have been posted.

Got everything installed today. Mounted the amp on some anti-vibration mounts. Very happy with how everything sounds.

Thanks, very informative. I'm just not sure if I have the ear for tuning. I will definitely give it a shot, though.
