I doubt I will be entering SPL competitions. It's just that I'm a bit of an overkill person. I like knowing I can, it doesn't necessarily mean I will. I prefer things to be done properly the first time around.
I'm not sure on the impedance rating yet. I was considering 4 ohm coils, but I haven't thought about it too much. I have too many things on my mind to get into the details right now, but any advice will be appreciated.
I will be installing the amplifiers into a custom perspex display box that will replace the centre of the rear seat in my wagon. There will be two sports seats on the sides, and the amplifiers will be made into a feature. I will probably also end up running a capacitor in the setup too, so having one amplifier will help there.
