With the information that you've provided, I can offer you this: I would wire it to match the lowest compatible impedance between the subwoofer and amplifier.

odds are its a dual 4 ohm sub, and ur amp is only 4 ohm stable when bridged making a bad combo

not bridged it cant, best bet wire the coils in series to 8ohms bridge the amp but power output wont be that great, its not a good sub amp combo.

According to the manual that amp bridged can only handle a 2 ohm load. If you've tied the +'s & -'s of the voice coils of that sub together and wired them bridged to the amp then you're driving it harder than it's designed to be driven and you're going to burn it up.

You could wire it in series as Greg suggests or just wire each of the voice coils to separate channels on the, getting 90W into each of of the voice coils on the sub. This is the wiring Greg suggests:

Your amp would likely be putting bout 165W into the sub this way so you'd get a bit more by wiring it stereo but your enclosure may not permit it.

Hmm I know the amps been running bridged for at least 4yrs since Ive had the car and its always sounded great, When i did my dd i did some upgrading and I unhooked the sub to remove I took a few pics but when i went back to check they werent clear, I know the amp is not running in stereo currently. My interior lights are dimming now with the addition of the 4ch amp... But they never did before?? Only when the bass hits...

Yes, it's stable @ 90x2 into 2 ohms when I looked it up.
