ya thats how i ran my sub for awhile with a old sansui reciever.
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.
im just sayin that the link doesnt provide any wiring for this setup at all
And like I said above, try this diagram
. Instead of 2 drivers, wire to the 2 voice coils of your single driver.
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.
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 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.
