Upgrading 8" Woofers for 8 Speaker System, maybe same for 4 & 6 speaker system? Options

How To Upgrade Your Stock 8" Woofers
-----------------------------------------------

The woofers are JL Audio 8W1V2-4 but any 8" (or 20cm) woofer will do.






Step 1: Once you've removed the woofers from the doors, you'll need to remove the 4 screws under the foam surround and pry off the old woofer.

Step 2: Then you'll need to cut the sides of the hole on the speaker adapter (shown above) to match the diameter of the magnet going on.

Note: You'll also need to cut about the same amount of metal on the doors for the woofer magnets to fit.

Step 3: Then you'll need to cut the 3 braces on each side depending on how deep the new woofers go.

Step 4: Then you tap new holes along the rim of the new woofers to match the existing anchors, and use the existing screws to mount the woofers.

Step 5: Just splice the old connector with the new speaker wire to connect to the new sub.

For best sound quality, do not use these with the factory stereo system.

yeah they're subwoofers. i think the stock woofer amplifier under the driver seat receives raw (unfiltered) audio signal from the amplifier in the center dash panel. so i plan to replace the amp under the chair with another 2-channel amplifier. looking at the wiring diagram, it seems pretty straight forward and it has the + & - audio signal for each woofer, battery, switch power (ATT), ground, and mute. But i'm not sure if there's sufficient power coming in on the wire harness for the amplifier so just to be safe i plan to run a separate power & ground cable from the battery. i want to run a 400W amp that can still fit under the driver chair.
