how do I connect subwoofer cables to a car amplifier?

So I have a Rockford Fosgate T1500-1bd amplifier

Its got 2 channels for speaker cables, channel A and B

On my subwoofer I have 2x 4 subwoofers which lead to a single cable, black and red cable

So how do I connect this speaker cable to the amp?

to channel A plus and negative? that means channel B is empty,

or do I connect the red subwoofer cable to the plus on channel A and connect the black subwoofer cable to negative on channel B? so looking like a bridged connection?

The amp is a constant power amp so its confusing on how to connect this amp to the subwoofer

thnks

Mr Noob,

The T1500-1bd is a mono, single channel amplifier, the speaker outputs labeled "A" and "B" are wired in parallel ("+" connected to "+","- connected to-") internally.
Two four ohm drivers in parallel = 2 ohm.

Connect one of the speaker leads to a "+" connection, the other to a "-" connection.
Make sure neither speaker lead is connected to the car's chassis.
