I just bought an 02 Yukon and was wondering what it takes to replace the factory sub in the rear. Do you have to run a new amp and power source, wires, etc... with the factory head unit. I haven't taken the panel off yet to look but thought I might get some input on here first. Any input is appreciated!

I'm pretty sure when I pulled the factory sub it was already running at 2ohms, so unless you but a dual two ohm and ran it at 1ohm you wouldn't get any more power out of the factory amp and it probably wouldn't sound good. There are a lot of amps out ther now that will let plug high level inputs (speaker input) directly into the amp so you don't have to replace the HU.

So I think as a minimum you need a new 8" subwoofer and an amp with high level input and it will give you quite a bit more bass then your getting now.

Optimally though, a new box, 10" sub, HU, amps, and new components are really necessary to get good quality sound.

Hope that helps.

I've got an 02 and mine sounds like poop, too. lol, go get a multimeter from an autoparts store and use it to find the impedence of the woofer (ohm load). Once you find that, you can start deciding what kind of woofer you want to replace it. I unhooked mine and dropped in a Resonant Engineering SX 15" in a 5.5 cu ft box tuned to 30 hertz powered by a JBL bp1200.1.... It's a lil more than stock, to say the least

you could jsut replace it with any 8" sub if i remember correctly.. wont do much w/o an aftermarket amp though
