24-pin Subaru Harman Kardon and/or Toyota JBL Amp Turn-On Adapter
Item Number: AHH-7583
This is the amp turn-on half of our Harman Kardon / JBL amplifier adapter set. The factory amplifier has two connectors: a 30-pin connector carrying the speaker signals, and this 24-pin connector, which carries a +12V ignition-switched wire.
The 30-pin AHH-7881 jumper gives you the speaker signals, but it does not include an amp turn-on or +12V ignition wire. If your aftermarket amplifier or powered subwoofer needs a remote turn-on lead, you need this 24-pin adapter as well.
These factory systems do not provide a true amp turn-on output, so the ignition-switched wire broken out here is what installers use for remote turn-on.
Do I need both? If you only need speaker signals and your amp switches itself on by signal sensing, the AHH-7881 alone is enough. If your amp needs a remote turn-on wire, order both.
What's included:
One plug-and-play 24-pin jumper harness for the factory Harman Kardon / JBL amplifier, with the +12V ignition-switched turn-on wire broken out as a labeled flying lead.
Installation:
Unplug the 24-pin connector from the factory amplifier, plug this adapter in between the factory harness and the amplifier, and connect your amplifier's remote turn-on lead to the broken-out +12V ignition-switched wire. No cutting of the factory harness is required.

Price: $25.00
Vehicle Fitment:
(If a known model is not listed, let us know)
Fits only vehicles whose factory amplifier uses the 30-pin connector (and its companion 24-pin). Not every Harman Kardon or JBL car does - several generations use a different amplifier connector and need a custom-built adapter instead.

The first model year carrying this connector on Toyota and Lexus is approximate, so please check with us before ordering for an older vehicle.
Does NOT fit - ask us, these are custom builds: the earlier Legacy and Outback, where the Harman Kardon amplifier is driven at low level from the radio and has no 30-pin connector at the amp; the SJ-generation Forester, whose Harman Kardon amp is a 10-pin plus 12-pin pair; the VA-generation WRX and every WRX STI; the BRZ; earlier Toyota and Lexus JBL systems; and Lexus Mark Levinson, which is a different amplifier entirely.
