wiring 2 channel amp to dvc?

In wiring a 2 channel amp to a dvc, do you run one channel to each coil? that just does not seem right.

Re: wiring 2 channel amp to dvc?

huh?? that doesnt explain anything.....they are bridging a two channel amp....way different than using 2 channels of a home stereo.

It depends on which diagram you look at. Try this diagram for stereo subs. It will do the same thing for 2 voice coils in one driver. If the two channels are being run out of the LFE pre-out, there won't be any difference in the signal.

What equipment are you using, model numbers, etc.

My HT sub is currently set up like this, and yes, you wire one coil to each channel of your amp. Use an RCA Y-cable to get from LFE out on your receiver into the LR input of your stereo amp. That's basically it, easy as pie!

ya thats how i ran my sub for awhile with a old sansui reciever.

im just sayin that the link doesnt provide any wiring for this setup at all

i assume the 80w per channel i had made 160w total, and each coil driven at 8 ohms.....but functions as a 160w 4 ohm load? not sure how that works or if the 160w 4 ohm is better or what. does it matter if two channels are driving the sub or if you have a mono amp and make it 4 ohms at the speaker...is there any performance differences?

If you're using a receiver, then yes, a y splitter is what you need to get the input to both channels. If you're using a pro amp, then it may well have a parallel switch, which will take the input to channel 1 and use it for both channels.

And like I said above, try this diagram. Instead of 2 drivers, wire to the 2 voice coils of your single driver.

If you wired each 8 ohm voice coil to it's own channel, then you had 160W, assuming each channel was able to drive 80W at 8 ohms. The impedance seen by each channel was 8 ohms, not 4, they are separate circuits, so the impedance is unchanged.

There's nothing "better" about 8 ohm vs. 4 ohm, it depends on what your amp can drive. In this particular case, with a DVC driver, (two 8 ohm coils), a mono amp that puts out 160W at 4 ohms is approximately equal to a stereo or 2 channel amp that will output 80W per channel into 8 ohms.
