Ohm Loads

[kickasskid544]

when you wire two 4 ohm speakers to one channel on an amp it forms a 2 ohm load correct?

If you wire it in parallel yes, if in series then its an 8 ohm load

EDIT: here ya go:

even if were dealing with single voice coil subs?

[finkster]

yes, check my last post again

parallel is + to + and - to - of both speakers. This will lower the ohm load. in the case of 2) 4 ohm loads, it will half it. here is a formula

(R1 x R2) / (R1 + R2) = final ohm load

Now you can also do a series circuit. this is + of one sub to the amp, - of the other sub to the amp, then connect the remaining + and - together. This will result in the impedance being added together so in the case of 2) 4 ohm loads you have 8 ohms.

if you had one single voice coil sub at 4 ohms and wired it up, it'd stay 4 ohms. wire another one in parallel, and it goes down to 2 ohms. wire it in series and it goes to 8 ohms.

thanks every1 for clearing that up i knew almost everything you guys said accept how the ohm load went up never knew that but my buddy didnt know any of it he thought if you had 2 4 ohm subs and you wired them to 1 channel it stayed 4 ohms so i had to clear that up with him

Just making sure, this also goes for speakers as well right? for example 6x9 with 5.25 both at 4 ohm in parallel will do 2ohm?

yes, it goes for speakers too.

It goes for any electrical load. like motors, resistors, light bulbs. its a basic rule of electricity.

Alright sweet! I just wanted to make sure before I fucked something up haha.
