There is no need to change the battery cables. I am not sure if your "high grade audio" means a high power amplifer. If you are hooking a high power amplifier of 150 watts RMS total or higher, you should run the amp feed wires directly to the battery by using the correct gauge wires, usually a #6 minimum and higher, with a fuse in line (series). This way the amplifier, which is placing a high electrical demand, will not burn up the OEM wires. A #22 gauge wires will NOT handle the amplifier's electrical demand. DO NOT be "wired for fire." BTW. If you are using a high power amplifier, make sure your battery and especially your alternator is up to par to supply the amplifier's demand at full power draw and or with your A/C running. With these two units running, the standard OEM alternator, will not or will just barely supply the electrical demand, thereby shorting the life of the alternator or your battery. I am presently deciding to replacing my high powered amplifier from a JL Audio 300/4 to either a McIntosh MC404M, a Zapco 4.0 X, or a Sinfoni Amplitude 120.4X for a better sound quality as audiophile quality and not the "boom box" sound. If you need more info, email me privately not to tie up the bandwidth of the DML.
