Removed from my 99 NB with Bose System with cassette.
1. Aux-In Mod: buy a switch of your choosing, and plug it into the spade connectors.
Plug it into the back of the head unit and you're ready to go.
Fused for head unit protection.
Has a 3.5mm jack so you can patch in any length of audio cord you want.
Reusable crimps so you can lengthen the 3.5mm jack if you really desire.
2. PAC Sni-35:
Allows you to add in an extra amplifier.
Simply taps into existing radio harness to create 2 RCA outs.
$16 shipped for *both* anywhere in continental US.
