I'm working on installing a custom audio secret car radio SST-V in my 62 Impala. I was wondering where I could draw power from the instructions say to hook to acc. I tried using the power connector from factory radio but it doesn't seem to have enough power.Any help would be great. Here's a link to the radio https://www.classiccarstereos.com/secretaudio-hidd...

What leads you to believe you don't have enough power?

I was using the original radio power lead but doesn't have enough current to power radio. I'm looking for a connection that work in acc and run positions

If you can believe the radio specs at 200 watts output, that equals slightly over 16 amps @ 12VDC input. I believe the original radio lead is fused at 9 amps. Also the original lead is probably 18 gauge. I would run a 15 amp fused 12 gauge lead directly to the battery positive.

Run a power wire as large as you need direct from battery through a relay that is controlled by ignition run/ACC

What exactly does the radio do when you hook it up to the original radio harness?? The 200 Watt rating is a pipe dream. The wattage ratings are often greatly exaggerated to make them appear more powerful than they really are. You're lucky if you actually see 12 or 15 watts rms per channel power level on this unit. Take a look at the original wire harness supplied with the new radio. If it were 200 watts the power line would be a very heavy gauge wire. This wire appears to be about the same thickness as the other wires in the harness. You'll need two power sources, a constant 12volt line to maintain the memory of the radio, and a switched line to have it turn on and off with the ignition switch.
