To connect an additional subwoofer to an existing 5.1 home theater system, first check if your AV receiver has a second subwoofer output. If it does, you can simply connect the new subwoofer using a subwoofer cable.

Ensure that the volume levels are balanced for both subwoofers during setup for optimal sound quality.
To add a subwoofer to a Pioneer T1808 receiver in a Scion xD, you'll first need a powered subwoofer that has speaker-level inputs or a line-level input. If using speaker-level inputs, connect the subwoofer's inputs to the receiver's rear speaker outputs using appropriate wiring. Alternatively, if the subwoofer has a line-level input, use a RCA Y-splitter from the receiver's pre-out to connect to the subwoofer. Ensure that the subwoofer is properly tuned and positioned for optimal sound quality.
