Quick sub install question

[Buckeye Boater]

I've ordered a Bazooka Amped sub to install in my AR192. The install seems pretty straight forward to me but I have one question. I get the power, ground, turn on wire set up, but for the signals there's conveinent RCA outs behind the clarion head unit and I plan on using those, but I've seen where people prefer to splice from the rear speaker wires?

Can someone explain the advantage/disadvantages to using the RCAs?

Rca is the way to go.
Some head units even let you tune the rca seperate. They are much clearer quality.

Speaker wire setups can let you turn it up or down by fading front or back.

I ran mine off of the RCAs as well, worked just perfectly.
