I've now sorted mine, so can tell you....

The wires for your under-seat woofers are thicker than the others coming out of the amp.
Thick black & red is Left woofer +ve.
Thick black & brown is Left woofer -ve.
Thick blue & red is Right woofer +ve.
Thick blue & brown is Right woofer -ve.

In this same loom, you will also find a thin white & red wire, which doesn't twist round another (as all the other speaker wires do). This wire is an ignition live wire that can be used as a remote to switch an additional amp on.

Hope this helps.
