using a resistor???
Is it possible to use a resistor in your setup to add resistance? Say if you have a dual 6 ohm sub ran in parallel to 3 ohm adn a 4 ohm stable amp; can you put an actual 1 ohm resistor in the path of the subs to get 4 ohms?
just curious???
thanks

Re: using a resistor???
I wouldn't know what it would do car audiowise so I can't tell you what it does to the subs but since I am studying to be an electrical engineer, I can tell what the resistor does in general. If you do put a reistor in there the resistor you add will use up some of the power you are hoping to get. The power you get at 4 ohms will be split between the 3ohm impedance (from the woofer) and the 1ohm resistor. The subs will probably be looking at only 3/4 of the power that amp puts out (at 4ohm) since the resistor will use the other 1/4 power (resistors are current dissipators). I think that you will also need to find a resistor that can take that kind of power however. That a lot of current for a little 1 ohm resistor. The amount of heat that resistor would generate would be up there.

Yep, like he said.
I'd rather take my chances that 3 ohms would be OK and just keep the gain down than lose 1/4 power heating up a big resistor.
