How to add a subwoofer?
Car systems and home systems are different in the fact that the car system expects to receive 12 volts DC for power, and they are usually 8 ohm speakers. I would not recommend doing this unless you are in the mood for some serious config. Power converter from 110 AC-12v DC and big enough to handle the amperage. If it's not powered, then your going to be running a 4 ohm speaker on an 8 ohm amp output. Again, not recommended.

Speakers cut out
Are the speaker leads clean and full? ( not missing a bunch of strands) if so, it sounds like the spot where the speaker connectors tie into the circuit board inside.
I would find someone to solder that places where the connectors go into the main circuit board

JVC RX 709V Will not turn on stanby keeps
There is most likely a fault in the power supply that is causing the amplifier to go into protection. This receiver more than likely has a switching power supply you can tell by the weight of the amp. Heavy = linear power supply and light = switching power supply. Common problems with switch mode power supplies are the FETs used for switching and the PWM (pulse width modulation generator) If you know someone into electronic repair it should be too difficult. The FETs won't be cheap. Though. All in all the unit should be no more than 100 dollars to repair between labor and parts.
