I just installed my deck, amp and sub in my car, everything works well except for the subwoofer won't make any noise.
All wires are correct per the diagram from the install manual and the amp is powered and lit.
I have tried all 3 rca jacks (rear output) with and without the amp on several different speakers and none are producing sound.
I have gone through the sound settings and it tells me that the sub is on.
Could all 3 channels be blown?

You should have two (or more) RCA plugs on the back of the deck that will act as pre-amp outputs for subwoofer and speakers.
Failing that, your wiring harness should have come with a wiring diagram that will let you know which is the subwoofer output.
Failint THAT, the deck itself should have a wiring diagram on the bottom or side telling your which wire is which.
And if that fails, Your deck may not have a subwoofer output. Just attach your sub to the amp pre-out like everyone else.
You can connect the regular preamp outputs to a sub amp. Dedicated sub outputs will normally have a built-in crossover whereas the regular front/rear preamp outs will be full-range. Just make sure that the amp you use for your sub(s) has a "low pass" filter.
I know this is an old post but just ran into the same problem with my brother in laws Pioneer Radio. Well, it turns out that the head unit has to be OFF before you try to change the subwoofer setting. THen press and use the Multi-Control knob to select SubControl and change this to REAR SP: FULL (this gives you full range sound) or REAR SP:SUB W (this is for only low, subwoofer frequencies). His radio was set to sub, which is dumb because it was installed with a 4 channel amp and 4 full range speakers. Not sure why it was setup like this in the first place but oh well...
first check that the subwoofer function on the actual head unit is turned up,second check that the gain on the amp is at bout half way then check that it is on a lp (low pass setting)
then check that the boost on the amp is turned up.
please leave feedback.
the connections to the amp seem to be all wrong .check the wiring again.Does your deck have a seperate sub woofer output ?If it does , just connect one sub, i repeat, just one sub,and see the output.
check the GAIN control on the amp.it should be 2/3rds of the max volume of the cd player.check it is not zero!
Set the amp to the L.P.F. position.
bye .happy listening.
You need an active subwoofer input in your amplifier.Which amplifier you are using? Only latest pioneer amplifiers has active sub input and sub output which can be connected to subwoofer.If you dont have active input then you will have to connect it the way you did in old player.
