Would this work? Also tell me the problems that could occur....?

Question

Ok, I want to be able to completely kill my amp (remote wire kill switch) and be able to listen to my music through my speakers still (same speakers that are connected to my amp)

Note: these are component speakers (two 6X9's & two 6 1/2's)

What if I/Can I, connect a Y splitter to each speaker terminal on each speaker and connect one end to my amp, and the other to my existing speaker wires coming from my headunit?

P.S. I've starting to doubt this idea while I typed it, but go ahead and tell me what would happen if I did it, and I don't know a way to kill the output from the headunits speaker wires so if anyone knows how to do so without having to install multiple switches, please tell me.

Thank you in advance people.....

Answer 1

Here are two way to go about it, the first is the easiest but involves some risk, the second method is more difficult but fail safe.

You could use a A\B speaker selector switch and wire it backwards with the speakers hooked up to the input terminals, head unit speaker wires hooked to A terminals and amp speaker wires hooked to B terminals. If wired in this manner it will allow you to switch sources but be cautious if it has a "both" setting. Placing the selector switch in "both" could damage the amp & head unit.

Another way to do it would be to use a 3 way switch and a group of 12volt relays. This would require more work but would be fail safe and would not risk damage to your amp or head unit. You would wire the 3 way switch so when it is in one position it closes the relays for one source(HU) and when it is the other position it closes the relays for the other source(amp). This is the correct wat to acomplish what you would like to do but it will require more parts and assembly.

Answer 2

diode isolate all of your speaker wires. then there would be no routing of power from one unit to the other............

Answer 3

ive never done somthing like that but im pretty sure you cant listen to them while ur amp is turned offf

Answer 4

i not quite sure why you would want to do this, but it can be done. you would just need an a/b switch for each speaker to go back and forth between the sources. dont use a separate switch for the amp and the HU to a single speaker, you may for get to turn off the HU before turning on the amp and you could fry your HU....get an a/b switch to prevent this.

at this point you would have 4 switches...it would be nice to control them all with a single, master switch.

i have heard of people doing this but on;ly for turning the sub on and off.....not totally power swap for all speakers.

you best sound quality and power will always come from an amp over a HU....again, i don't see the point.
