weird readings

[agiletick 0]

okay so i have 1 set of components right now and it was reading 4ohms at the amp i got another set and was short of wires right now so i just jumped off the first 2 figuring i would just run 2ohms untill i get more wire in so thats 2 6.5s and 2tweets and now at the amp i am STILL reading 4ohms i poped doors back apart aech driver is reading 2ohms on driver side they are in series running to passive crossovers but when i check input side of the crossover it reads 4ohms no matter how many speakers i put to it i even tried running all 4 to 1 channel and i still get 4ohms could the crossover have a way to change the load like this?

The short story is yes, measuring the input side of the passive crossover is not going to give you an accurate representation of the attached speaker load.

Also, your plan to connect 2 pair of speakers to 1 passive crossover is not a good plan. Changing the impedance of the load the crossover is connected to is going to change the crossover frequency (among some other things depending on what circuits the passive crossover includes) which is going to seriously affect performance in a negative way. If you connect the tweeters in such a way that causes the crossover frequency decreases you now run the risk of blowing both tweeters.

Passive crossovers are designed to operate with a specific load attached to them.....you do not want to change that load or negative things will happen.

so would it be better to split the input and run both crossovers or just not run second set at all until i get more wire

Are you running both sets up front or front and back?

What if that load stays the same, but two crossovers are paralleled from the amp??

If I'm understanding your question correctly, what you're describing won't have any effect on the passive crossovers but it will affect the load your amp sees.

To the OP: I guess I don't really understand what you are trying to do. As 98GMC basically asked, what exactly are you trying to do here?

i was running 1 set of comp off 2 channels of 100.4 i added another set in doors right beside the first set i plan on running them off the other 2 channels but my wire wont be in for about week so i was just running them all off 2 channels

Personally, I'd just wait rather than jerry-rig it. When people are impatient and start trying to make something work is usually when mistakes are made and things start getting damaged.

If you're impatient, you could always just grab the necessary speaker wire locally.
