Or a stronger wife.Congrats.Next time get a bigger bike.
It may be a relay problem. Does it make a click a few seconds after you turn it on?
Yep, time to check if there any type of speaker relay where contacts could be corroded, or it's not pulling in fully. Could be also bad DC output so it's in protect mode, needs additional troubleshooting.
Does it have any pre-out / main in jacks? Then you can split the sections and see which one isn't working right.
I picked up a Sony AVR receiver on the curb that had practically no output on one channel, even after a DeOxit treatment to the controls. So I took off the cover, hooked it up to some test speakers, and used a chopstick (non-conductive) to tap various components inside, and located a ribbon cable that was making poor contact at the board. Wiggled that around, applied some Tweak, and it's now in the AV system.

Ribbon cables - more than a few times, reseating these (including in my own Sony receivers) has been the cure to the problem. Excellent suggestion.

That's a nice find, but I pity your bike's rear wheel.
Hook the sub up for the garage system or add it into your main system, one can never have too many subs.
Well done. Not many people have a spouse who would A) let them pick up garbage at the road side B) allow A) while they were present and C) assist is dragging A) home using pedal power. Heck most couples can't even cooperate long enough to ride a tandem bike.
That is about the third or forth wheel we've had on there, and I just put two new spokes on the backup wheel. You are right about the rear wheel taking a beating. There is a lot of torque and weight on that wheel. Glad I had that tire aired up good.
