i want to keep my power antenna switched down at the dash when i play tapes or listen to my cds through a Sony tape/cd adapter, which btw works great with my portable Panasonic cd player. the sound is truly amazing for a $20 adapter... this is on a stock '88is head unit. i know that there is a white wire from the head unit powering the antenna, but it also powers the amp and if you disconnect it the antenna goes down, as desired, but the radio and tape stops playing as well. i don't want to run a long wire from the trunk (where the antenna is) to a switch at the dash. anyway to get around it? thank you
