i have an odd situation. my 06 gs has the ML system, which was nice, but i decided to upgrade. we were able to integrate new surrounds and subs with the stock by using an audiocontroll lc6i. everything married up perfectly, and sounded great. the only issue, is that after tuning (within 30min) the driver door (midrange) speaker has lost signal. we traced the issue back to the ML amp. it is no longer outputting signal to just that speaker. all others are fine. no wires crossed to short anything out; this is very puzzling given that it was working fine, then just quit. there is no difference in the setup between the driver and passenger doors (crossover, power, ect). has anyone experienced this? is there a possible reset on the amp or headunit that may help this? i currently moved the jumper on the lc6 to bring in full signal from the rear input to the front, so i have music at least, but it does not sound anywhere near as good. any help would be much appreciated.

 

Did you try to pull the plugs on the ML amp and reconnect to make sure your connections are still good. Also check your audiocontroll to make sure all connections are good. If not this i'm sure someone here may have another suggestion.


I also have a GS, may I ask what color the wires were at the ML amp for the sub only? I can only find info on the pioneer system on all of Lexus data sheets.

 

i do not have the spec sheet in front of me, but i think the pink and blue wires are the sub channel. i will check and see if i can verify, and i will let you know.
as to the connections, all have been verified tight, as well i disconnected the battery for a few minutes and unplugged the amp. everything is connected correctly. it makes no sense that one speaker channel would go out in this manner...

 

pink wire with blue dot and solid blue wire paired with it is the sub channel. not certain if there are multiple pairs of wires that color though. wasnt trying to tear everything back apart here at work. lol
