Sub removal help

scorpio stu · 8th February 2016, 21:09

Hi all
Just bought a car that had a sub and heavy duty wiring to the head unit. The seller took the sub out and disconnected all the extra wires from the head unit.
When I turn the stereo in the only sound is very faint from the rear tweeter.
My question is, would someone disconnect the rear speakers when you have a sub in ?
Fronts work fine by the way. I'm a bit stumped and just asking before I whip off the door panels. Thanks

Not normally but peeps do some strange things

Most of our cars (unless Highline) don't have rear tweeters fitted though, they have full range units at the bottom of the door and the place where the tweeter would reside is usually vacated

Yep that is correct, My rear tweeters are disconnected as with them connected it makes the sound drag from behind but no it does seem weird that the person would disconnect the speakers though, Isnt the original wiring loom still behind the headunit ?

Just checked the rear speakers and all connected. Looking at the wiring it seems as it should be other than the sub wires which I've disconnected and removed from the car now. Still no noise from the rear but front is fine ?

Was the sub being directly fed from the head unit or a dedicated sub-out from the head unit to a separate sub-amp? Or was it fed from the rear speaker feeds to a sub-amp? If there was a sub-amp is it still there now, and if so is it powered? What head unit is it?

Lots of questions - no answers I'm afraid, but maybe the answers to those will help find the problem.

I wonder if the person had disconnected the cables behind the head unit, perhaps because he wired the sub to them as a high level input rather than line level?

The head unit is a Sony xplod
There are extra cables at the rear where the sub was plugged into. All unplugged now. The sub had an amp attached in the box in the boot and that's all been taken out as well. Plugs on the head unit are all in place as they should be. Thanks for the replies

Without looking up the manual for the Sony, I'd guess that there may be some settings on the head unit that need changing. Maybe there's different output (tone/equaliser) settings for the rear speakers that were changed due to the sub being present?

I did think that but sure I've tried every possible setting. Will try again
