Hey guys, I am looking at bridging my Parrot BT module between my headunit and amp. Here is what I am looking for:

2 x dpdt 12v relay (silver contacts maybe?)

Any help would be appreciated. Thx

you wouldnt want silver contacts. they will corrode very quickly. if you want nearly no loss and high reliability. look at solidstate relays.

My first approach was to build an N-channel mosfet setup but the price would be to steep for my $40 dollar blutooth setup. Solidstate relay's also run around 50 a piece... eek!

Dragonrage - Do you have any experience with using a standard spdt bosch relay for audio? I am trying to stay awayfrom the clipping sound is possible :(

Thx!

I'd use some small relays for audio signals, not the big beasts with big windings inside. You can get some tiny dpdt 12v relays from digikey, last ones i got were under $10 each. some specify whether they have an off state between no/nc modes, I'd think you'd want one with a smooth transition to eliminate pops.

please note i have not run audio through these, tho I'm now very curious.

I have run audio through a dpdt switch without much issue tho...
