New sub hook-up question

[Yay-Boost]

Got a new sub showing up and was wondering what the best method to hook it up would be. It's a 12" with a dual 4-ohm voice coil. I bought it from Crutchfield for $106 shipped to my door with the q-logic box. I plan on buying a mono sub amp and rewiring the sub to 2-ohms this spring. It's too damn cold to rip my car apart right now. So till spring it's going to be the stock amp. Should I just hook it up 8-ohm like the stock piece of junk? Or should I hook it up not bridged to each voice coil with the amp running both channels at 4-ohm's? Would there even be a difference between these different set-ups?

You should never send different signals to the different voice coils on a sub. You only have two options with a 4 ohm DVC sub. Wire the coils in paralell for a 2ohm load or wire them in series for an 8ohm load. If the stock sub was an 8 ohm SVC; wiring the sub in series should work perfectly until you get a mono amp.

A side note: There are cases where people have used a separate amp for each voice coil on a sub but they never do so with a stereo signal. In any case it is not recommended.

I didn't mean I would be sending a stereo signal to the sub just meant that I would be sending the same signal thru 2-channels of the amp. I thought part of the reason for a dual voice-coil was to be able to run 2 amps?!

No.

It is designed to provide more wiring options as to maximize the output from your amp.

Perhaps bi-amping was a thought in the beginning but now that amplifiers can power several high-power subs, using two amps on a single sub is pointless. It is cheaper to buy the next model amplifier. Like I said, you can still do it, but your sub works best when both VCs are working together with the same signal at the same volume. There is too much margin for error when you are dealing with separate amps, and when the VCs aren't working together you risk overheating the sub and frying the VCs

Cool, Learn something everday. I guess it would be alot more expensive with multi-amps.
