Purchased this for an amp that didn't have speaker level inputs, but realized my amp was broken so I bought an amp with speaker level inputs- rendering this LOC unecessary in my setup.

It literally spent about half an afternoon in my car as I was troubleshooting my setup, and is practically brand new. Comes in original packaging, all documentation, and is perfect. I'll even include the receipt from where I bought it.

You'll need this device for using your OEM headunit while upgrading to an aftermarket amplifier that doesn't have speaker level inputs. (i.e CD43 in e30)

$120 shipped is what I want for it.
