Bi-polar, also called NON-polar, electrolytic caps are used in circuits
where you need to pass an A/C signal while blocking DC. You can use two
polarized
caps in place but must add a steering diode pair to prevent overvoltage
failure. This is especially true in high current circuits as in audio
crossovers and
horizontal coupling circuits.
This article written by Joe Sopko from "The Speaker" shows the proper way to
make up a sub using polarized E caps:

Just a small question here. I have came across a bipolar electrolytic (I
understand these can be inserted any way around in circuit?? - NEED
CONFIRMATION) and was wondering what advantage these have over a normal
electrolytic?
Could a normal electrolytic capacitor be used in place of this?
