I have a 2003 Toyota Avalon. The factory headunit has 5 wires going to the factory JBL amplifier. One wire for each channel and a "SIG GND" wire. I think the "SIG GND" is a shared ground. After the amplifier the speaker wires for each channel have both a negative and positive wires. I have a JL audio Cleansweep I want to install. Is there any way to install the cleansweep before the amplifier? The cleansweep has a positive and negative lead for each channel, but there is only one wire per channel coming from the head unit. I tried connecting all the cleansweeps negative input wires to the shared ground from the head unit but the cleansweep said it was not receiving any signal. I tried measuring the output from the head unit with a multimeter but could not get any reading. I would like to avoid installing the cleansweep after the amplifier because 1) I planned on using the space under the seat for the cleansweep and 2) I cut the amplifier wires too close to the wiring harness and it will be difficult to hook the amplifier back up. I can e-mail the wiring diagram.

No- it's not meant to be hooked up to a common ground system so you'll have to connect it after the amp. If you cut your plug too short, you may try removing the pins from the harness one at a time, and reconnecting the wires and reinserting them- unless you can find another harness at a junk yard.
