Subwoofer Question

it does not affect your lows, the ohm load has to do with how much power your amp will send to each sub. If you have 4 ohm dual voice coil sub, it just gives you more ways to wire them up, series gives you 8 ohms, parallel gives you 2 and if your amp is 1 ohm stable, you can bridge that to your amp and get 1 ohm. If you have 2ohm dual voice coils, you can wire it in series and get 4ohms, if you do it in parallel, it drops it into 1 ohm. If your amp is not stable in 1 ohm, then it means you have to either run each voice coil separately from each channel or wire it in series to get 4 ohms where your amp is more stable.

Subwoofer Question

What are the advantages/disadvantages of a (2ohm + 2ohm) woofer vs. a (4ohm + 4ohm)? I know that the amp has to be 2 ohm stable to run the first kind, but does this allow for lower lows or what?

basically if you have an amp that is 350watts RMS @ 2 ohms and you use a dual 4 ohm voice coil sub, the resistance is 2 ohms and you get 350 watts to the sub when wired in parallel, when wired in series you get 8 ohm which is 1/4 of the power. If you have a dual 2 ohm voice coil sub with the same amp wired in parallel it drops the resistance to 1 ohm and not to many amps can handle the lower resistance from this, when wired in series the resistance is 4 ohms which means it's getting 1/2 the 350..so 175watts @ 4ohms. I hope this helps

Um wrong, the amp needs to be 1 or 4 ohm stable for the first kind and 2 or 8 ohm stable for the second kind... unless you're running more than one sub. It just gives you wiring options to match up with an amp. The fact that they offer both means you can use any amp, so pick out the amp you want and then come here and we'll tell you which model sub you need.

um you don't drop your wattage that much with higher resistance.. ..

This is the amp that I am going to run two ten's off of. So which ones do I need?

You need two 2+2 ohm speakers for that amp.

Good Luck!

ps - basically you need each speaker to operate at 1 ohm or 4 ohm.

Many Thanx!
