hey if i have a dual 8ohm sub and regular 4ohm sub and wire it to a 2ohm amp will i have problems same brand of sub.

In theroy if you the ohm load wont make a difference as long as its a 4/2 ohm load on the amp. But if its not a MONO amp, you cannot connect a 8ohm sub and a 4 ohm sub to 2 different cahnnels on the amp, you will fuck up the mosfet output configuration voltage.

In series:

8*4 = 32

32/16=2

So you'd have a 2 ohm load.


In parallell

12 ohms LoL


So dont fuck anyhting up. Just get the same model sub.

yeah it would be in series,its a mono amp see. this is the real situation.

2-dual 2ohm subs and a dual 4ohm sub

wire the dual 2ohmers down to a total of 2 ohms between the pair.

wire the dual 4ohmer down to a total of 2ohms

ive now got 2 sets of wire carrying 2ohms each

hook it up to a 1200w at 1ohm amp so i can have my total 1200w.

WRONG

the resistance of 2 of any thing in parrallel will always be lower then the lowest resistive componet in parrallel

look 1/(1/R1+1/R2)

1/8 = .125 1/4 = .25

.125+.25 = .375 1/3.75 = 2.66666666666666 ohm

series would be 8+4=12ohm

he got series and parallel mixed up. :uh:

Using subs with coils of different impedence will result in some woofers getting more power than the others.

Sure, you can calculate the overall load just fine. But the woofers will not be getting the same power. One will likely be getting twice as much as the other.

I did not, and the guy dosen't know the forumal for parrallel any how.....

reciprical is the only way to go btw unless they are equal resistance

Jeremy is right, but the more important thing is do you want to have 2 different subs when people look...... if there is a difference

any ways I tend not to comment as much on audio stuff cause I don't got time to discuss a lot
