Topic: rocker switch to amp

Subject: rocker switch to amp
Date Posted: April 02, 2007 at 4:59 AM

Hello All,

Its either my laziness, or stupidity, but I couldn't seem to find a thread on these forums that explain how I would install a rocker switch on my amp. I currently have my amp being turned on whenever my head unit is turned on but I sometimes drive around family members who don't quite like my subs, so I was wondering how would I go about installing a rocker switch to control only the amps power.

I have a 3 prong illuminating rocker switch and I couldn't seem to get it to work the way that I tried it so I pretty much just need an explanation of what wires I need to throw on what prongs. Any information would be helpful so please don't shy away from the thread.

Thanks for your time.

You would need to cut the remote wire.  Connected the radio side of the remote wire to the 'In' terminal of the switch.  Connect the amp side of the remote wire to the 'out' terminal of the switch.  Connect the remaining terminal to ground.

Make sure you insulate all connections and don't leave any metal exposed.  Most HU don't fuse the remote wire, so you'll actually burn up an internal circuit if you ground out the remote wire.

Please let me know if this explanation of what I am going to do when I work on it is correct.

1 - Disconnect battery.

2 - Cut remote wire.

3 - Install radio side of remote wire to "12vlt" connection (In) terminal.

4 - Install amp side of remote to "Acc" connection (Out) terminal.

5 - Install ground wire to "Ground" connection and the other end to metal surface of cars chassis.

6 - Wrap off connections with electrical tape.

7 - Connect Battery.



And after that it should work right? Its a little too early to start installing for me right now because my neighbors are asleep and its not even 7:00 AM out here but in a few hours I plan to do what I just listed and see how that works for me.



I'd like to thank you for taking time out of your schedule to help me with this installation and wish you the best of luck.

sound like it should work my friend. thanks for such a polite post! Did you already find a place to mount your switch? I've seen far too many installs that just have the switch dangling out the rocker panel

I personally wouldn't bother with disconnecting the battery.  Just make sure the radio is 'off' and the remote wire won't have any voltage on it.  If you are extra cautious disconnecting the battery won't hurt, it will just take longer and require you to reset your clock and presets.

Good luck!

Hello again everyone.

I've just got back and I must say, I amazed at how nice this switch works for me. I'm glad that this forum is filled with nice people such as the ones that posted responses in here, and I'm sure there are plenty more I've yet to meet but I'm glad to say I'm a member here. I'd like to thank all of you for your time. I highly appreciate all of your help and doubt I would of figured it without you all.

Thank you all once again. If there is anything I can help you with, please feel free to ask. I'll look forward to talking with you all on my later projects.

I hope you all have a nice day.

sbkspyder said he's using an illuminated switch. I am, also. I was wondering of this is 'pulling' too much power from remote wire and if this will burn it up? Should we be using relays?

Thanx

The light in the switch should draw a minimal amount of current.  If this is a concern you can do an amp draw on the light.  I wouldn't guess that it would be anything to worry about.

Alright. I've just heard that remote wires only have like .3 amps or something and was really just wanting to know if it'd be better to use a relay.

Just use a DMM and wire it inline before your switch...setting should be on milliamps...then you'll know

Since you are using a switch anyway, you can transfer the remote wire to a switched 12 volt source rather than the radio's output.  Use a 1 or 2 amp fuse on the source end of the wire.  (Although I personally wouldn't worry that the LED in the switch would cause excessive amperage pull from the deck's remote output.)

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Yeah, thanx stevdart. I just was making use of my remote wire. I know what I need to do now.
