2006 Sienna JBL - Subwoofer control

Post by cdlenfert » Mon May 21, 2018 11:48 am

I've got a JVC-KW-M730BT head unit (I previously installed a Pioneer 1330NEX). I've also got the Maestro RR unit. Everything is connected and working well. The only thing I can't figure out at the moment is if there is a way to control the output of the factory subwoofer? I can control gain on the AMP and hear overall volume raise/lower, but when I go into my equalizer settings, which is the only place I can find controls for the sub) and take the level from 4 to 10, there is no noticeable (or actual) difference in the output from the subwoofer. I seem to recall clicking around in the vast array of options before and getting some control of the sub, but I've looked a couple times since and can't seem to find it anywhere.

Any advice? Is it possible? Thanks!

(side notes for other Sienna upgraders):
  • I switched to the JVC from the Pioneer because I gained a USB port, dual zone AV output, larger screen, and it was cheaper!
  • I had to hard wire the reverse signal from the factory reverse wire (luckily I have an OEM backup cam and the wire was already in the dash)
  • I opted to bypass the parking brake wiring, but it was on the same plug as the reverse signal
  • I wasn't able to retain the factory AUX input through the T-01 harness, so will have to hardwire that to the JVC
  • OBDII on the 2006 doesn't work through the Maestro unfortunately

There is no control over the factory subwoofer with the TO1 firmware. As for the other features not working, this was a contributing factor to why the vehicle was recently removed from the list of support vehicles.
