You can replace your audio and receive transistors with a new one or a compatible one and be back on the road again. the transistors are available from all ham dealers and are normally not too expensive.
do not try to fix something that ain't broke. if it is working, leave it.

Suburu radio wire harness. trying to match up with a new soni deck


Hello uze7, Here is the wiring match up for a 2009 Subaru Forester using the Metra 70-7552 wiring harness: NOTE: The actual harness will be listed as a Nissan harness, but has been used by Subaru since 2007. Also, I'm assuming that your Sony deck uses the standard color code. If not, you should have a manual that lists the function along with the colors. Match the wiring by function, not by color (although the colors may be the same). 2009 Subaru Forester Radio Wiring Color Code: Battery BLUE/RED (+) RADIO HARNESS Accessory YELLOW/RED (+) RADIO HARNESS Ground BLACK (-) RADIO HARNESS Illumination VIOLET (+) RADIO HARNESS Dimmer BLACK/WHITE (-) RADIO HARNESS Power Antenna YELLOW/BLACK (+) RADIO HARNESS LF Speaker (+) BROWN LF Speaker (-) BROWN/WHITE RF Speaker (+) BLUE/WHITE RF Speaker (-) BLUE/YELLOW LR Speaker (+) WHITE/BLACK LR Speaker (-) RED/YELLOW RR Speaker (+) GRAY RR Speaker (-) GRAY/RED Metra Harness: Yellow ? 12V Constant Red ? 12V Accessory Black - Ground Orange ?
