Hi All, new to the group here.
I've been looking around the forums for about a week now to find out this exact thing, as i have just fitted my sub in the boot with the line outputs taken from the Yellow Mini ISO connector on the back of my Alana MP3 HU.
Works just fine. I even made up the cable myself from a spare Mini ISO i had lying around.
The pin outs are indeed correct from the earlier post, with pin 6 being the remote wire to turn the sub on. Pins 1 , 2 , & 3 are the line outputs for LR , RR , and earth. Only one set required for the sub.
Now I have a working Sub from the standard HU, and I also installed the Sony 6 Disc multichanger (T70) , via a connect2 interface into one of the other Mini ISO's. This also works 100% and fits into the glove box like a ,,,ummm glove !
Sound quality isnt fantastic, but adeqate for a standard head unit. I'd say when funds allow , I might change for a better HU, and an adapter to retain steering wheel functionality, which I believe are available from caraudiodirect.com.
