Subs not working after amp install?

[Lensman]

Hi all. I've installed a 4 channel amp (Kenwood KAC-M3004) which has speaker level inputs with adjustable gain, high and low pass filters with adjustable frequencies for both for both channels. I think I've used all possible combo's of the filters and frequencies, but I just can't seem to get the subs to kick in. Am I missing something simple? (VE SSV)

I used the Aerpro bluetooth kit to avoid hacking into the factory loom.

Is the amp turning on?

Yes it all works great, except the subs aren't working. I'm starting to think that maybe the sub amp is not powering up due to something I've not reconnected?

Still no joy getting the sub amp to kick in. I've checked the relevant fuses. I'm now thinking I've run the battery down to a voltage (10.8) which might be too low for it, so once charged up I'll check it again. I did find this useful pin-out diagram for the sub amp connector.

Hi Wraith. Thanks, there is 12v at the sub amp if that's what you mean.

Is there any lights on the amp itself?

There are no lights on the unit, it's a stock VE SSV sub amp. If I take the amp out of the loop (T Harness) the subs work fine. Put the amp back in the loop, subs stop working. I have adjusted the gains and frequencies up, down and sideways on the amp but it makes no difference. It's starting to do my head in.
