How do I remove a radio?

<< < (3/4) > >>

Disco Matt:
I think so - not 100% sure. There are definitely only two wires as the subwoofer is mono (stereo wouldn't be noticable at such low frequencies).

I wired mine across both rear speaker outputs. As they have their own amp they haven't melted the head unit, they're only picking up a signal from there after all. The bass is somewhat amazing and had to be turned down a fair bit to avoid sounding terrible. Not an audiophile solution but my new radio didn't have a subwoofer output!

JumboBeef:
Right, thanks.

So could I wire the red and black onto one of the L R pre-amp outputs of the unit?  I assume the black would go on the outside and the red on the inside.....?

Jamin:
 A quick way to find the positive and negative wires on a speaker, if not marked (red i should imagine is positive) is to get a little 9v battery and press the wires on the terminals. the speaker should push out or suck in, you have correct polarity when it pushes out.

JumboBeef:
Thanks.

I wired my red and black wires to one pre amp out (red to the centre and black to the outside) and......nothing.  Any ideas what I should check now?

Disco Matt:
Mine refused to work with the subwoofers connected to the pre-out and the rear speakers connected as per normal - seemed like the head unit could either feed the pre-out sockets or the normal outputs, but if you connected something to both it only fed the preouts. I wasn't sure if this was normal for all head units but it seems as if it is.

If you leave the subwoofer disconnected and just plug the head unit into the standard connector, do the rear pillar speakers work? If so then you need to pick up a signal for the subwoofers from somewhere. I connected mine across the rear pillar speaker feeds which works but may well be doing horrible things to my radio. It isn't causing it to overheat though, as the subwoofers are only drawing a signal from the head unit rather than the power they need to work.
