wiring sub to amp problem

[j.o.n]

i have a BLAUPUNKT GTA 460 Amplifier. its a 4 channel amp. i have 2 6x9 speakers running of it. i cnt get the sub working of it. any ideas how to?? or is the sub broken. everything is brand new.

amp power up fine?
are the 6x9s powered off the amp and playing ok?
check connections from sub to amp, making sure wired up correctly.
If all wiring is ok, and 6x9s are working ok, could be faulty sub.

Oh and try swapping the connections from the 6x9s and the sub, so the sub is running from where the 6x9s where connected, to make sure its not the connections off the amp.


Oh and are the amps fuses ok in it - has 2 external fuses being a 4 channel?

amp is powery fine.
6x9s working grand.
everything seems to be wired fine.
tryed swaping the 6x9 wire with the sub. sub still didnt work.
i was thinking the sub was faulty. is their any way to check that it is faulty?
fuses in the amp are grand.

try another sub in there or try that sub in someone elses set up.

On your head unit yu dont have a subwoofer button do you (like on alpines) where you can adjust how much volume is going to the sub.

check that the volume on the sub isnt turned down - will be under settings and will come up "subwoofer" make sure its set to max (iirc its 15 max).
