First off, what is the 4 channel amp being used for. I am assuming for 4 door speakers? Second, is the 1 output from your deck a full range output or non-fader only?

Use 2 Y-cables.

In general a 4-channel amp is not the best solution for subs, but it can certainly be used. Make sure your impedance load on each bridged set of outputs is no less than 4-ohms and set your gains and LP crossovers properly.

Yep, that sounds about right. Unless you want to buy a good line driver that can create multiple outputs from one, or replace the amp with a proper subwoofer amp, this is the only thing you can do. Install the Y-cables and then properly reset your gains.

Sounds to me like you would have to upgrade your cd player first. You should get one with 3 sets of rca outputs. 1 for fronts, 1 for rears, and 1 for subs. You could use signal sensing to the amp but it just doesnt ever sound all that great.
