I'm looking for some help on determining which switch I need for my install. I want to have a switch that switches my dual 2ohm voice coil sub from series to parallel and vice versa. I have found this article on Instructables on how to go about this, which is fairly straight forward:
SIMPLE Parallel/Series Select Switch
The reason I would like to do this is I don't need all that power to my subwoofer on a daily driver, but would like the option of sending more to the subwoofer for competitions. With that being said, I need some help determining the switch I need.
1. The max power of the amp I am planning on running is 1500 rms x 1 at 1ohm. With a Peak output of 3000 x 1. I am assuming to determine the capacity of the switch, I multiply amps * volts (ex. 16a * 125vac = 2000 watts). Should I be looking for it to meet the Peak output, in this case 16a would not be large enough? Or as long as it can handle the rms at 1 ohm is that ok?
2. I noticed many switches have more than one "rating". For example this rocker from parts express: DPDT Rocker. It is listed as 16a/125vac and 10a/250vac. How do I know which one to go by? I've also seen some show both a resistive rating and an inductive rating. Which would a speaker be?
3. I also found this article which shows a similar method using relays and a switch to control the relay. Would this be a "safer" method? The only issue I have seen is that relays only come in 30a/12vac, which is only 360w. Is there a workaround for this issue?
Any insight would be helpful.
