Budget subwoofer? (lemy.lol)

Hi there.

I'm using this unit here: https://www.amazon.com/dp/B09YNBHR73

The issue I am having is subwoofers and not having a lot of money to fix my situation.

I currently have that 3 x 8" ported Skar box, but it has such low impedance that the speaker safety trips constantly on it. Godzilla help me if someone says a word with a p in it.

Is there a way for me to rewire that setup to gain more impedance and stop it from cutting off or should I move on and get a single 12" for the small box I have? (I have a behind the seat single 12" enclosure.)

I'd obviously love to have bass as deep as possible, but any options would be nice.

Thanks

You would want the single coil version so that you can get 4 ohms. H7124S (https://www.amazon.com/CERWIN-VEGA-HED-200W-High-Energy-Subwoofer/dp/B071ZC4FQL/ref=sr_1_1)

I modeled the single coil version and this is the response you can expect: What you can get out of this graph is that you won't get much bass below 40Hz and a peak around 70Hz.

Sorry, confused as to why I'd want SVC over DVC when they are the same Ohm?

Because with 2x 4ohm voice coils you would either get 2ohm in parallel or 8ohm in series. Neither are ideal. With a single voice coil you get a single 4ohm input. DVC is really ideal if you have two channels that you want to connect to a single sub. Each channel would get 4ohm.
