how do i wire 2 svc subwoofers at 4ohms to read at 2ohms with a 2 channel amplifier?

Question

Trying to wire in my car, please help

it has to convert 4ohm svc subs to 2ohm svc subs with a 2 channel amp


i have to see the diagram please? Any help please????

Answer 1

If you're trying to make EACH sub work at 2 ohms so that you can hook one to each channel on your 2-channel amp, then give it up, you can't do it. You can COMBINE the subs for a total 2-ohm load, and if your amp is stable for 2 ohms in bridged mode, you can wire it that way; but most 2-channel amps can NOT handle a 2-ohm load when bridged.

To wire the two subs together for a combined 2-ohm load, just wire the two positive speaker terminals to each other and to the positive output on the amplifier. Do the same with the negative terminals. But don't connect it in this way to the "bridged" terminals on your amplifier unless you're certain it's rated to handle 2 ohms when bridged.

Answer 2

you can wire the two 4 ohm subs in parallel to get the resistance down to 2 ohms. But, with a 2 channel amp you would have to wire both subs on 1 channel (left or right) to make the subs run at 2 ohms in parallel. This is because of the internal resistance of the amplifier. The only other option would be to "bridge" both channels of the amp and run them to the subs, depending on the amp it could fry the voice coils and the amp if you bridge both channels and run the subs in parallel. The only amps that will do this are competition amps that are rated at 1 ohm stable, because bridged to two subs in parallel runs at a little over 1 ohm. If you do not have a 1 ohm stable amp your best way of wiring the subs is just 1 sub per channel. Hope this helps!

Answer 3

Well you bridge the amp by running the positive from one channel and the negative from the other channel. That is bridging the amp. That will run the amp on a 2 ohm load. Now for the speakers...take the + wire and run it to both speakers and the - to both speakers. Now by doing that you will bridge your amp and run 2 4ohm speakers at a 2 ohm load. be careful cause your amp can overload if it is not 2 ohm stable.

Answer 4

Your amp would have to support stereo to mono bridging (which can give you up to 4x the power). But unless your amp's output can drive a 2ohm (2 4ohm speakers wired in parallel) load without takin' a smoke, you'd have to use only one 4ohm speaker, or 2 in series (being sure to keep the phase correct) but that would give you 8 ohms and less power. If it were me, I'd take what I had into a shop and see if they'd make a equitable quality trade... to get the right devices for the job. Why skimp for a minute and suffer suckiness for years? It ain't worth it bro! But good luck!

Answer 5

Unless your amp will run at a 2 ohm impendance while in bridged mode, you can't. And most two channel amps are limited to a 4 ohm load while bridged.

Answer 6

YIPE... that is almost a dead short... you had better have one hell of an amp to push a load like that.

Wire them in parallel with positives together and negatives together... BUT THAT MAY BE TOO MUCH FOR YOUR AMP..
