I just installed the unit today. My front and rear speakers are connected to a 4 channel kenwood amp 1 speaker per channel. I connected the FR, FL, RL, RR RCA's on the back of the pioneer. But I am unable to get any sound on the rear speakers the front works fine. But If i turn on the subwoofer mode the rear channel starts working but it will only play the low frequencies like a sub. How can i get all 4 channels to play with out it thinking 2 of the two rear channels are sub outputs. When i turn off the sub mode it plays no sound at all. I have adjusted the setting fade to rear as far as it can go to test the rear speakers.

The instructions show that the rear can be used as a rear output or a sub output so am I missing a setting here? currently it is set to Sub off. F&R fade is in the middle. L&R blance is in the middle. What else can i change?

Hey Bling,

I have the exact same problem. Mine is wired through a Metra harness to retain the factory amp in a 2002 Lexus IS300. Were you able to find a resolution to this? Does anyone here have experience with this same problem?

Thanks.

no i have not yet found the solution so if anyone has any thoughts on this that would be greatly appreciated. Thanks in advance.

Ok this is how the problem was solved for my situation:

See Pg.39 of your manual

-------------------------------------------------------

Setting the rear output and

subwoofer controller

This unit’s rear output (rear speaker leads output

and RCA rear output) can be used for fullrange

speaker (FULL) or subwoofer (S.W) connection.

If you switch the rear output setting

to S.W, you can connect a rear speaker lead

directly to a subwoofer without using an auxiliary

amp.

Initially, the unit is set for rear full-range speaker

connection (FULL). When rear output is

connected to full range speakers (when FULL

is selected), you can connect other full range

speakers (REAR) or a subwoofer (S.W) to the

RCA rear output.

! When the multi-channel processor (e.g.,

DEQ-P8000) is connected to this unit, you

cannot operate this function.

1 Touch REAR SP on the initial menu.

2 Touch < or > next to REAR SP to switch

the rear output setting.

Touch < to select full-range speaker and FULL

appears in the display. Touch > to select subwoofer

and S.W appears in the display.

# When no subwoofer is connected to the rear

output, select FULL (full-range speaker).

# When a subwoofer is connected to the rear

output, select S.W (subwoofer).

# When the rear output setting is S.W, you cannot

operate the following procedure.

3 Touch < or > next to PREOUT to switch

the subwoofer output or rear output.

Touching < or > will switch between S.W and

REAR and that status will be displayed.

Basically the setup for the Rear needs to be Full and not as 'S.W.'

Give it a try, it solved my problem. After this, you shouldn't be able to control your 'Bass' except through 'Bass Control'

thanks that was exactly the answer I was looking for I did not know there was a initial settings menu. I guess i need to explore the unit interface more.

Wow this helped me too. I had spent hours trying to figure this out and checking connections, taking out my HU/dash, etc. I thought I checked all menus but apparently never could find the inital menu, now I know I guess. Thanks to google for pointing me to the anser finally.
