| Weird problem with subwoofer remote wire (Alpine SWE1200) | |
So I can't seem to get my subwoofer remote wire powering up my subwoofer after installing a second Life4P0 aux battery.
I've got a separate fuse box under my cubby box where im getting my power from for the subwoofer. If I connect the remote wire to the same plus as my subwoofer it powers up just fine. I've got around 13.5V there.
However the remote wire coming from the headunit is dead, less than 1V coming from the wire. Connecting it to the power wire of the radio also doesnt work. The radio works just fine though. However I can't find any 12V from the wires there.
After hours of messing about my last idea was to go to the factory fuse box and get an ignition live. Went to fuse 44 which is a 5A Fuse for the Radio. Checked with the voltmeter and I've got around 12V coming through there once the ignition is on. Connected that to the remote wire and .... nothing happens. Started the engine as I thought it might be the problem - still nothing.
It seems weird to me that the 12V coming from the fuse box doesn't power up the subwoofer but going directly to the extra fuse box coming from the Life4Po works just fine. However I dont want to have to install a switch and always have to turn it on and off... problems started once I installed my second battery. I tried with two different SWE-1200 subwoofers - so that isn't the problem either.
Any ideas? This is making me crazy....
