buy/setup help: Bridging, DVC, etc.
this probably seems like a stupid question, so sorry for those who roll their eyes...
I've decided to get a Profile 4-ch 1000w amp. I'm looking at 12" Eclipse 6123's, 4ohm. If I buy two, and the min. load for the profile is 4 ohm, (4ohm stable), would a Dual Voice Coil sub do anything for me? cuz i could get a 4ohm sub, or a DVC sub. A better qestion maybe is what would i need to do to drive two 4 ohm subs? would it be better to buy DVC subs at 4 + 4ohm? remember my amp needs min. 4ohm load when bridging. thnks in advance.

Re: buy/setup help: Bridging, DVC, etc.
Short answer: Two 4 ohm subwoofers or a single 4-ohm DVC sub will give you the optimal load for that amp.
Long answer: Dual voice coil configurations are mainly for flexibility. For example, if you want a 4 ohm load for that amp, you can use a single-coil 4 ohm subwoofer, a single 2-ohm dual voice coil, or two 4-ohm dual voice coil subwoofers. Read on if you want know know how that works. If you have two 4 ohm DVC subs, you can make each subwoofer a 2 ohm (or 8 ohm, but we'll stick with 2 for this example) by connecting the positive and negative of one coil, to the same pole on the other coil. This effectively makes the subwoofer like a single 2 ohm sub. Next, you run the two subwoofers in series, by connecting the positive from your amp to a positive on coil 1 of one sub, then from negative of coil 2 to positive of coil 1 on the second sub. Then, finally, from negative of coil 2 on the 2nd sub to negative on the amp. This may be confusing at first - if you want, I can draw a diagram. Baiscally, wiring coils in series adds the impedance (ohms) up, and running them in parallel cuts them by the number of components wired in parallel, and you can combine series and parallel circuits. I'm going to assume you want a pair of 4 ohm loads, using your amp's 4 channels bridged down to two channels, right? My above example will give you 4 ohms. If you're even more confused now than before, just say so and I'll try to clarify.
