What does it take to make a remote switch for one of these amps? The amp already has the socket on the back. Do I just wire a plug and put a switch across the wires or is there more to it? |

who did i forget to fully answer that question for? actually, i think it was a texas star question....
the amp switch in the off position...the remotes' switch takes the 12 volts & puts it across the amps on off switch to turn the amp on, technically immediately beofre the amps' on/off switch.
so yes, you're just putting another on/off switch into the jack. just make sure you have the proper pos/neg leads, & that the jack is wired to switch ON with the amp in the OFF position. got that? |

I think i've got it, but you threw me off with
" just make sure you have the proper pos/neg leads"
I havent opened the amp, but how I understand it is:
Wires on the remote jack are connected to each terminal on the amp's on/off switch. The amp's on/off switch is left off and the switch plugged into the remote completes the circuit. Is this correct?
I don't understand where the pos & neg is an issue when technically all I am doing is putting a jumper across a switch, or does the remote jack on the amp actually need 12 volts to trigger a relay? |

your middle statement is correct, 'raker.
as for the the 1st & 3rd comment...if you reverse the pos & neg, the amp would need to be in the 'on' position for the remote to shut it off or turn it on. thus depending on where the jack is wired, even with the remote 'off', power could be going to the amp... |

OK, before I went to the trouble of running the wire and building my remote box I decided to put the pluug in the amp and put a jumper across the plug to see if it would work. First I had the amp switch off, when I jumped the plug it arced and burned the wire. Then I turned the amp on and put the plug in, the amp went off and I heard an arc inside the amp (i didn't have the jumper on yet). I took out the plug, the amp wouldn't work at all. When I took the top off I found the wires on the amp switch had heated up and came unsoldered. I resoldered the wires and all is good. I dont know what went wrong, but am going to solder my remote switch directly across the amp switch (I can't think of any reason why that won't work). Maybe this bit of info will be helpful to someone else, like me, who is too cheap to buy the remote with the amp and decide to make their own. |

recently put a 4 pill magnaforce in a truck. wired a piece of rg58 across a phono plug, routed coax under mats & to a switch mounted on dashboard. no problems. that's how the NJ & NC davemades work, & all xforces i've seen that have built in jack. if you wire plug backwards, switch on amp works in reverse, but you want remote to work with amp switch in OFF position, not ON-that feeds power to amp all the time. possibly jack wired incorrectly? or it's wired to use external power? not sure what's up with that.... |

I looked at the wiring on the jack and am still mot sure how it was supposed to work, but I used the jack to run the wire through that I soldered to the switch inside the amp. I mounted a switch and an LED inside a project box I got from rat shack and stuck it to the bottom of the radio. It works so I'm happy. Thanks again. |
