John, first take your battery to your local auto parts store and have them check to see if your car battery is holding a charge. If your car battery isn’t holding a charge, it may not be able to support your amplifier and subwoofer. If your car battery is holding a charge, you may have a faulty alternator that cannot handle charging your car battery and run your your amplifier and subwoofer. If you car battery is not holding a charge, we suggest you get a deep cycle battery. A deep cycle battery will give you more battery power and charge faster while providing twice the life span of a conventional battery. As for your power wire, as long as it is connected straight to the positive terminal of your battery you should be fine. ope this helps. Good luck with your 2004 Chevrolet Avalanche troubleshooting.
