9515ROB Posted April 24, 2012 Report Share Posted April 24, 2012 .25 ohms is where its at never have the amp play above 1 ohm even on music i like fire balls coming out of my amps!!!! what i got at .5 ohms thats why i sold all 4 of my 7kd's. I didnt like the way they looked, they scared the fuck out of me - 1998 Ford Mustang - Time to rebuild. 4 15s and alot of power TEAM DTF Link to comment Share on other sites More sharing options...
HHR Ed Posted April 24, 2012 Report Share Posted April 24, 2012 Hi , I would like to know if it possible to wire 2 dual 4 ohm sub down to .5 ohm ? If yes , how ? Thanks No, Ohm's law works like this. Electrical resistance is measured in Ohm's In a parallel circuit, resistance is lowered. This is measurable with a simple formula. 1/ (1/r1+ 1/r2+ 1/r3+ 1/r4) = Final ohm load Your voice coils are the r, and you have 4 of them. so 4 4ohm coils in this formula are 1/ (1/4+ 1/4+ 1/4+ 1/4) = 1ohm That is the lowest you can go with what you have. Series circuits increase resistance. The only way to get more power, in a safe manner is to get a larger amp that does more power at 1ohm. To get a lower ohm load on that amp to 2 woofers, you need to use Dual 2ohm coil woofers. But your increase in power will be very small compared to the increase in heat, distortion, and danger to equipment.

ALPINE408 Posted April 24, 2012 Report Share Posted April 24, 2012 .25 ohms is where its at never have the amp play above 1 ohm even on music i like fire balls coming out of my amps!!!! what i got at .5 ohms thats why i sold all 4 of my 7kd's. I didnt like the way they looked, they scared the fuck out of me i still run them... at or above 1 ohm there awsome you scruured? lol pussy if i need more power i buy a bigger or but the same amp and have 2 i will not go below 1 ohm ever again have had nothing go pop since then and that was years ago Have you ever had your woofers blown?

skittlesRgood Posted April 24, 2012 Report Share Posted April 24, 2012 so thats why you hate .5ohm If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.
