I bought both of these from Crutchfield 1+ years ago, but just pulled them out of my boat installation over the weekend when I revised that (dumped my amplifier in favor of just feeding Empeg into HU AUX to reduce battery drain)

You probably know what these are if you are reading this. You can find descriptions and pricing on Crutchfield Web site. My pricing?:

Sony XA-39 dual head unit switch $25 + $5 shipping
Audiolink speaker-->line-level converter $15 + $5 shipping

I'm guessing that shipping these out of the U.S. would make this proposition not very cost-effective, so shipping quote is just for U.S. Drop $5 shipping if by chance you want both items. Payment by (non-credit card) Paypal or money order.

E-mail if interested.
