Is more ohms better or worse? (i've been told that less the ohms more the power) isn't there more volts in lower ohms? would that mean that there is more pwer flowing to the subwoofer?

i have a Sub that has the Speaker wire going to the one voice coil and a wire that conects + to - on the other voil coil. isn't that adding ohms? wouldn't that reduce the amout the sub can be Fead? some guy told me that it inproved the sub? but from my understanding the lower the ohm the better?


also how many watts can 8 gauge handle? (RMS) And how Many with 4 gauge? how about doubling up 8 gauge? would it be double?


Thanks

is the sub dual 2 or a single voice coil sub ? , if its a daily driver setup your pretty safe running at 2 ohm

schickj

well this is a MA audio 800watt 6 ohm dual voil coil (dont know rms Guessing 250?)
but i dont care much about this sub. im just trying to learn and make my next set up awsome.

luke99

what amp just run it at 2 ohm

schickj

xm-dtr6001 class d. and you mean wire it to 2 ohms right?

luke99

ya 20hms is a good for daily

I'm going to answer the first half for you in general terms... Hopefully it helps lol Electricity follows the path of least resistance. Ohms are a measurement of that resistance. The higher the resistance, the higher impedance is acting on the electricity, so less power will be available... Here... If you have 2 power supplies that have a given, constant, and equal power output and 2 different loads (one @ 4 ohm, the other at 8) the "load" is not going to be able to utilize the power available the same way. One of the loads is of higher impedance, so there is a "loss" of power. Most of this loss is heat, the other is the simple fact that 100lbs is harder to lift 6ft in the air than 50lbs, so it takes more work to get the same job done with a higher load. In audio, a higher impedance generally means that there is more control over the voice coil. With a higher impedance, the speaker isn't going to move as easy as one with a lower impedance, so to get the same level of output (SPL, for example) it will take more power. Think of a 1ohm load as one sheet of paper hanging flat in front of you... Blow out, paper moves pretty easily, then flutters back into its position. Now hang 8 sheets of paper held together and do the same. You'll notice right off the bat it'll take more "work" to get the paper to move the same distance, and you'll also notice there seems to be more structure as it moves, as the paper doesn't just flutter around, it will move mostly in one direction and return to it's original position. So... Is a higher impedance good or bad? Both. Good because it generally means better sound quality, bad because it takes alot of power to get high output, and obviously the opposite is true of lower impedances. The closer you get to 0ohms, the closer you get to a short circuit (like taking a wire from + to - on a battery) so lower impedances are harder on amps as well.

maybe i should just send you my questions. lol you always give a good explanation on them

The important thing is to match the impedance of the speaker to the best operating range of the amplifier. Having higher speaker impedance than the amp is rated for won't hurt anything but you won't get full power from the amp either. However, go too low with speaker impedance and you may damage the amp.

Car audio is all about balance.
