How to wire a 6 ohm audiobahn ALUM10N subwooferto reduce ohms to a single chanel amp

SOURCE: 6 ohm speakers - 8 ohm amp

This is a tough one due to the info at hand, but I'll take a stab at it.
I'll assume that your amp is not a tube-type amp. I'll also assume it is a relatively recent "solid state" design. If those assumptions are correct, connecting a 6 ohm load to an 8 ohm amp should not cause significant overheating or amplifier instability.

Here are the diagrams for running dual voice 6 ohm sub's.

SOURCE: replacing sub speaker

I wouldn't try reinventing it by replacing the driver. Drivers and their enclosures are designed to work together. And this being a self-amplified subwoofer, there is one more piece that's electrically optimized to the rest. Don't mess with it.

Why don't you just set your receiver's individual relative speaker volume levels so the sub isn't weak by comparison to your other speakers? Weakness, as you call it, is relative.

Is your receiver properly channeling Low Frequencies to the sub? Experiment with the cutoff, too.

This problem doesn't require meatball surgery.

SOURCE: Want to bridge 2 channel amp to push single 4 ohm dvc sub

Hello k_rabbit89,

A 4 ohm DVC sub can be wired in series like you described for an 8 ohm load or the voice coils can be wired in parallel for a 2 ohm load.

If your 2-channel amp isn't stable down to 2 ohms when the channels are bridged (most 2-channel amps are only stable to 4 ohms when bridged), you do not want the voice coils paralleled. The amp will overheat, go into protection mode, and eventually fail completely. A sub with 2 ohm voice coils would be a better fit. That way, you could series the coils for a 4 ohm load and the amp would operate OK with the channels bridged into that load.

But anyway, for the best power from THAT amp to THAT sub, your best wiring solution would be to wire each voice coil to a separate channel. The problem with that is that the signal to each coil needs to be EXACTLY the same or you will have one coil trying to move the cone out while the other one tries to move it in. You can closely approximate identical signals on the output side by using the same input to both channels. Do this by using only one RCA connection (either right or left channel) from your head unit and split it with a "Y" cable.

Hope this helps.

SOURCE: can I mix 6 and 8 ohm speakers?

Most Yamaha HTR's are high current receivers so setting the receiver to 8 ohms and running the 6 ohm speakers shouldn't be a huge problem. I wouldn't crank the volume though if i were you but at a decent level you should be fine.
