How do i remove the subwoofer? and can someone show me pictures of where the amps are? And would there be any problem with the head unit if i hook it up to a aftermarket amp and subwoofer.

amp is behind the rear seat rows the system is digital so the souce unit is just a big remote for the amp. You need to switch out both or go post amplification. Electrnically you cannot put an aftermarket amp just behind the source unit. If you have any further questions just ask.

i am right now leaving the factory amp to do the mids and putting in an aftermarket amp for the new jl sub i just put in with a Q sub switch. Will this work? If i want to change it all out later and put in new amps will the HU still work and will my 5.1 still work?

Yes, you can add a new amplifier to drive the sub--tapping the existing sub's amplifier signal. I did this as shown here: https://www.clublexus.com/forums/sho...d.php?t=272881 .

What's a Q switch?

If you bypass the ML amplifier, and you want surround processing, you will need a separate processor to do that, such as from Alpine or Harman. The head unit only outputs stereo, or from DVD, the Dolby Digital or DTS encoded bitstreams. If you just want stereo to drive multiple pairs of speakers, there's many ways to get there.

The OEM amp is located in the trunk, on the right side, under the floor mat.

bump, can anyone help me with on how to remove the sub?

DrexLex

You have to remove the back seats, various trim pieces, etc, as the sub is mounted from the top.

is there any thread that shows you how to do this, and would the dealer be willing to remove the sub?
