HELP wiring
SFB-8000D - Sundown Audio Monoblock 8100W RMS Class-D Amplifier,
I have it hooked up to 3 Skar Audio EVL-12 D2 12" 2500 Watt Max Power Dual 2 Ohm Car Subwoofer

and it keeps clipping shutting off how should I wire? i have all my setting really low so it does not clip....should i add a 4th sub?

should i buy the 4 ohm version??is the amp too big for them??

please any help thank you

You should probably wire each sub in series to 4 ohms, then each single 4 ohm setup in parallel to 1.33 ohms or so.

It's really simple.

Let's say you have a wire that's a foot long and it's 2 ohms. If you wire another wire side by side, it effectively makes a single wire that's now twice as large (diameter), so you get 1 ohm of resistance. If you connect the 2 ohm wire to the end of another 2 ohm wire, to make a 2 foot long wire (double the length), the resistance doubles to 4 ohms.

So all 3 subs at 4 ohms, when you run them at parallel, means 4/3 = 1.33 repeating. It should be somewhere around 1.3 ohms, 1.4, something close to that. If it's not, you've got a problem somewhere.
