Default Monoblock amplifier wiring problem.

Dear Friends

I have a monoblock subwoofer amplifier 600W

and also have two pieces of 300W subwoofer speakers.

Can I wire it parallel?

We will need to know what brand and model amplifier you purchased, and if the subs are multiple voice coils, and the impedance of each voice coil in order to answer your question.

Good luck,
Jason

It looks like the subs are dual 4 ohm coils, if you wire both voice coils in parallel and then both subs in parallel you will have a final load of 1 ohm at the amplifier. The amp you have is rated for a minimum 2 ohm load. So if you go that route you will be operating outside the manufacturers specifications. The protection circuitry may shut it down, but it may not as well. It is definitely not recommended.

If you wire the voice coils of each sub in series, and then the subs themselves in parallel you will have a 4 ohm load. You get the same result for the voice coils of each sub in parallel and the subs themselves in series. It ends up being a 4 ohm load. This is the safe choice to make, however, your amp seems to be optimized for a 2 ohm load. It makes a lot less power at 4 ohms. Honestly, I would try to get some dual 8 ohm voice coil subs, or single 4 ohm coils. Either route lands you at 2 ohms for the amp and that will get you the best results. You could also look for a different amp that can handle a 1 ohm load and go with the first scenario above.

Personally, if I were married to the equipment choices, I would just see how it would do with the 1 ohm load. I mostly deal with quite a lot older amp tech, and many of those would take their hot supper without complaining. I have no experience with any JL amps, but the common consensus seems to be that they are good quality. Ultimately it is up to you. Most of us here work on repairing car amps, so consider the POV that I am coming from. If I blow up my own amp, I can most likely fix it. That colors my advice a bit, so the safe bet is just to run it at 4 ohms.

Good luck,
Jason
