2002 Tahoe Subwoofer replacement attempt failed, can anyone chime in?

[greg716]

In case anyone finds this thread in the future, here's how the story wrapped up: The speaker blowing took out the amp, got a replacement used amp (because no new ones exist it seems), got a dual-coil Kicker Subwoofer from Crutchfield (4ohm) and wired it down to 2ohm, total cost was in the $75 range. The only modification required was to remove the plastic surround from the speaker but its just held on with sticky foam, then its a drop-in replacement into the stock plastic speaker box. You drill some new holes for the mounting screws and you're done.
Problem solved, and the new Kicker sub is a fairly dramatic improvement in sound quality even using a stock factory amp.

Sorry to bring this back from the dead, but I'm going through trying to decide how to upgrade the sub in my 01 Tahoe. Would you happen to have the Kicker model# you used, as well as how you "wired it down" to 2 ohm? I used to be a lot better at car audio and I can't recall what to do to change impedance.
