RCA Aux Input Switch Toggle

**mrmarbles** · 11-04-2005, 09:54 AM

Hello everyone. Been searching the forums for an hour now trying to see if this has been mentioned.

I have an Alpine HU with the RCA to AI-Net converter. I have an ipod and sirius radio I want to toggle between since I only have one AUX Input on my Alpine. I currently have my ipod and my sirius radio hooked up to this ugly switch I had for my tv. I know alpine makes a unit that switches between 2 RCAs and 2 CD Changers, but it's $149 for something I don't really need.

Is there a better switch I can buy or make thats not as big and bulky as this solution? What I would like to do is put a toggle switch in my dash to switch between the two. Any pointers would be greatly appreciated.

Thanks,
MrMarbles.

DPDT relay.

Why not use a relay with your switch?

I am going to put a 4PDT relay in a friend's car in the morning. Flipping one switch will throw the four signals (L+, L-, R+, R-) from either the XM or the aux input.

Thanks for the quick responses. I knew I could rely on a fellow matrix owner

I hadn't even thought of a DPDT switch. Do the left/right RCA cables have + & - or are they just one cable?

two rcas...both will have + and -

If you strip the wire, the + is in the middle and the - is wrapped around it. They should be separated with a tubing like insulation.
