Daviewonder 533 3 Cars Posted July 21, 2012 Hello All I'm planning on running a CD player in my Mini but the car already has an 8 Track player that I would like to keep in there. Does anyone know the safest way of doing this? Is there a type of relay that I could use so I only have power going to one device at a time? Would it cause an issue having both players connected to the same speakers, power from one head unit travelling down the speaker wires to the other? Could I use diodes to overcome this? Thanks Share this post Link to post Share on other sites
Weser 30 Posted July 21, 2012 I would use a relay on the ignition lives of both. I.e put ignition live on common then 8 track ignition live on NC and cd ignition live on NO. Use a switch to turn the relay on and off to switch between 8 track and cd. I would put diodes on for safety. I see no reason why that wouldn't work. Share this post Link to post Share on other sites
Tom Fenton 1,536 Posted July 21, 2012 Will diodes not mean you effectively cut out half of the signal range to your speakers? Share this post Link to post Share on other sites
Weser 30 Posted July 23, 2012 I am not proper clued up on diodes and speakers to be honest do you get reverse voltage on the speakers? It is an easy test though. I know you will get a volt drop over the diode so will lose some of the forward signal range. Whether it is audible or not I dont know? Share this post Link to post Share on other sites
