there is power to both the green wires but it's pretty faint (I don't have a multimeter but the test light shines extremely dim so I imagine the power going to those wires are low, any ideas on how to fix that?

I thought I would add that all other speakers work great

Did you make sure that the wires are not reverse polarized at the speaker or the head unit and that any splices you may have made didn't break? Is this an aftermarket setup or a Delco 2700?

A test light is not a good tool for testing speakers and the related circuit.. The current on the circuit is audio frequency, (a form of AC) not readily measured using conventional means.. Complex electronic testing equipment is required..

A quick and easy method is to disconnect the speaker and connect a known good one.. If sound is restored, you have a bad speaker.. If no sound, you have either bad wiring for that speaker or the speaker "channel" inside the radio is bad...

Like Nick suggests; the output to a speaker is an AC voltage and really can't be confirmed with a test light. Also, since that voltage is so low (like 1 VAC), it can be difficult to measure even when using a multimeter.
