I have 2009 Ridgeline, a Honda.
Unfortunately, I had Fry's installer take 4.5 hrs yesterday to "install" a powered subwoofer into my truck.
We decided to connect sub via RCA converter to a rear door speaker.
He had to remove several panels to run wiring, and he had sub working, with panels removed. It's a standard Red, Black, and Blue wire connection to amp. Blue wire is connected to a Yellow wire in what I am assuming is ignition harness, as it goes into the steering wheel under the dash.
Anyhow. Reinstalling everything back, he cross threaded seat belt bolt, that had to be removed to allow pillar B panel removal.
Both him and his partner spent another hour trying to install it back, and at that point, I got pissed, told them to reimburse me for install and clip panels back in place, and left.
I fixed the bolt at home but, same time, noticed that sub is, actually, not working.
There is no Power light on it.
I disconnected that sub, and connected to my Camry that has same connection in the trunk. Sub worked there fine. I took Camry sub and connected to the Ridgeline connections - no Power light, sub does not work.
Hence, it is not sub, but the way he had wiring done in Ridgeline.
I did voltmeter testing, and here's results:
WITH IGNITION OFF
WITH IGNITION ON
We did not have OEM headunit accessed, hence he tapped into that Yellow wire in the harness under the dash.
So, there is 12V to the amp; Ground is good; I am assuming, as I know nothing, that sub simply does not turn on from Blue wire.
I just double checked, and harness is definitely going into steering wheel.
I'd rather not go back to same fella, as now I am really upset. Any suggestions?
