Sure.

In light of info being floated by another forum member at this time, though, I want to say that much of that work MIGHT be able to be avoided.

The shop you're working with - do they have an audio analyzer or an oscilloscope? If they do, and they're willing to spend a little time testing, you might be able to perform a far more direct solution that I used.

They would need to insert a test disc with a sine wave, measure the preamp signal wires at the OEM amp (they are listed here somewhere), make sure that they find the set that stay the same voltage regardless of volume setting. Then disconnect the amp, then disconnect your battery for a while, then reconnect it, and retest the wires. If they now vary with volume, you have solved a big problem and only need an amp with balanced inputs or a balanced adapter such as a Soundgate LOCB.2 or a Peripheral SVEN.

If they have questions, they can email or call me. kenw at avincar dot com. 503 222 1305 .
