Bass blocker question

[gerald]

I have factory speakers(for now) and with my sub in, when i turn it up the sub sounds fine but the rear deck speakers pop. To solve this i bought bass blockers, they say to splice into the positive wire, but the factory wires arent marked positive or negative, so which color is which?

[inferno]

the lighter one

they arent black and red. One is Black and yellow, the other(this is off the top of my head) is green and blue? correct me if im wrong. but which would be lighter there? is there a way to check with a voltometer?

Light colors in front are +, dark colors in the rear are +

So in the rear..

Brown+/ yellow is -
Dark blue is +/ light blue is - i

hmm I'm not doubting you whatsoever, but why is it like that? Makes sense (at least to me) to keep the light positive

Because thats the way GM set it up.....?

I'm curious as to why this is happening. Have you played with the settings on your amp? You could always "unplug" your rear speakers and save some money.

I know when I put my subs in (many a moon ago).. I was using factory head and speakers.. and never had this problem.

Pretty sure you should let the amp control the bass and the head to control the volume.

Of course.. I tend to be wrong.


Good luck!

lets say my infamous sister who previously owned this car abused the factory speakers a little bit...

thanks for the wiring problem guys! sounds great now!
