Wiring subs for Series OR Parallel and using Relays to switch back and forth.

^ Diagram and quick write up.

So here is the thought- I know lots of people build their systems with the leads for the subs to the amps accessible so they can run "daily" at higher impedances and then at the show, move a wire or two and drop to a lower impedance for a few extra watts. Well, I'm lazy and I would like the ability to change it at will. On the fly so to speak. So...my question: has anyone here done that using relays? If so, how big of a relay or relays would one need? I know it depends on the power, but seems to me the little 55 watt relays wouldn't really be up to the task.

I have been toying with the idea of going a new direction with my sub amps, and that would mean running banks of subs at 4 ohms (or more) on the daily and then have a switch that sends signals to relays that would *BING* switch the wiring and impedance over to 1 ohm (or something like that). Just for burps, just for fun.

Picture:

Has anyone done this or seen it done? How does it hold up, what are the down sides, etc... It has my curiosity aroused. hehe

I've done this a few times but all of them were on low power systems. And never had a problem.

What kind of wattage is "low power" and what kind of relays did you use? The smaller 55 watt black plastic joints?

[Colin - STAPUFT]

No one else done this before?

I've never done this ... But Dang that's a fun thought.

I would experiment if I could, but don't have the equipment or time.

But like said in this thread ... I test on a small system, before Tearing all into the Van ...

^ thats what I had in mind first... even if I do this with the van, it will be a long time off. I'm itching to yank everything out and go B-Pillar. ...open the sliding door to a wall of old school...

But- probably won't ever do that. I couldn't fit my wife AND the kid! ...or the Pits bulls...

I considered this in the past, but I worried that relays would be inadequate,, would definitely be a point of resistance, and if one fails (through time) what happens to your amp(s)?

[Jessica]

well, its an awesome idea. what are your coils? 4,2, 1's?

edit:

how much power?

No way man ... It's unique the way it is now

I know somebody who might be right in the middle of this project....
