I replaced the center console subwoofer in my 04 sahara, and still not getting any power to it. I looked at the fuses and all were good. Im assuming the amp is blown, does anyone have an aftermarket suggestion that fits in the console? Also is that amp tied to the speakers as well? Ive noticed the sound is pretty subpar from all 4 speakers, PO isntalled pioneer speakers and pioneer HU. Just wondering if the amp would fix things before I go replacing speakers. Thanks!

The amp turn on needs to be wired in to either the power antenna lead or amp turn on lead from the head unit. When I swapped the head unit in my 02 I did not hook up that wire as shown in the diagram Crutchfield sent because I thought why would I need the power antenna lead from the radio hooked to the harness going to the Jeep...when the amp and speaker didn't work I knew why. Hooked up that lead to the harness, plugged it in and everything worked perfectly. Hope this helps
The subwoofer is powered by the front speakers, my bet is the previous owner didn't reconnect it to them. And my bet is the Pioneer speakers the previous owner installed have a low Sensitivity rating which means they require more power to sound good than the radio can provide. That's a common issue caused by improper speaker selection. And the more watts the speaker advertises it can handle, the more likely it is to have a low Sensitivity rating which requires a high power amplifier.
I'd convert all four speakers to either a Polk DB speaker or Kicker, they have very high Sensitivity ratings which means they were designed to not need a lot of amplifier power (wattage) to drive them. Anything with a 90 dB (decibel) or higher Sensitivity rating will be fine. And every 3 dB difference in the Sensitivity rating makes a huge difference. For example, a speaker with an 87 dB Sensitivity rating would require exactly twice the wattage/power to play as loudly as a speaker with a 90 dB Sensitivity rating. The Polk and Kicker automotive speakers have something like a 92 dB Sensitivity rating.
And make sure the subwoofer is connected to the front speakers and is getting 12 volts. The below shows the wiring colors for the subwoofer and where they connect.

what this guy said is what got mine to working after swapping out the factory head unit.
