I've had the parts and pieces to upgrade the SLE'* speakers/amp to the fullblown SSEi system (with bass amp, gain control, dual voice coil rears, and rear tweeters including speaker covers) because I can't stand the sound difference in the cars when they both have the same JVC head unit.
My problem is the bass gain control. I have a boost gauge in that location now. So do I relocate the boost gauge (I don't want a pillar pod in this car, but I could get creative) or relocate the bass gain control to somewhere else? I have the dash trim bezel I need for the OEM location on that.
For those than need pics, here'* the way the SLE sits today (remember the SLE never had a factory boost gauge in spite of the L67 engine, and the SLE now has an identical head unit to the SSEi pictured below):
Here'* the OEM location (my other car):

My extra trim bezel:
(keep in mind this will leave an extra hole where I don't have the HUD controls on this car)
