Speaker wiring question

[weedhopper]

I am replacing the radio in my Toyota. The new radio has paired wires for each speaker. The factory harness only has one wire to each speaker. I believe the other leg is via the chassis ground.

Can I connect one of the paired wires to ground or must I run the paired wires all the way to the speaker? If I am able to ground one of the wires, which wire would I ground, the solid colored one or solid/striped one?

Thanks.

do not ground the speakers from the new radio. does your factory radio have a separate amp? what model car?

Turns out that my Toyota has paired wires going to each of the speakers after all. What confused me was that the 12 wire harness has 5 smaller gauge(larger number) wires and 7 larger gauge wires. I thought the smaller wires were for the speakers, one wire to each speaker and the 5th one was common. Four of the wires went to the front speakers. The 5th wire, brown, was ground.

The larger wires included red, yellow, blue/yel, white, green, gray and black. For some reason, the black was paired with yellow for the LR speaker and the red was paired with white for the RR speaker. 12v battery was on the blue/yel wire. 12v ignition was on the gray wire.

The wire coloring was kind of unconventional. Does anyone know why they would use smaller wires for the front speakers and larger wires for the rear?

Thanks for the replies.
