does the amp see any difference between 1 sub @ 4ohms and 2 subs @4 ohms. does this setup put anymore strain on the amp then one sub.

Boy, isn't that helpful.
Andro,
If the load is constant, there shouldn't be any difference in what the amp sees regardless of the number of drivers. You are asking about simple impedance right?
My answer was as informative with regards to the solution as the original post was concerning the intent of the question. I was *trying* to make a point about the quality of the original question.
As far as the question posed and the answer posted so far, Cal, I agree with you.

its really a simple question, I was just wondering if its any harder on a amp to push 2 10s at 4 ohm to the amp, then 1 10 4 ohm to the amp. I have been seeing an issue that I do not understand. I have a amp that pushes one ten at 4 ohms with no problem but has problems when trying to push 2 10s together at a 4 ohm load. both tens are exactly the same. it has been my understanding that no matter how many drivers there are its no harder on the amp as long as the overall impedence is the same. so why would a amp go into protection mode at high volumes, with two drivers at the same impedence as 1 driver but it has no problems pushing the single driver.
ah... are the 1x10 and 2x10 the same driver? If so, then the 2 10s in parallel will be a 2 ohm load and a whole heckuva lot harder to drive than just one by itself. Two 4 ohm drivers in series would be 8 ohms and an easy load indeed for most car amplifiers.
For clarification: these drivers, are they all 4 ohm you are talking about? and do you understand the difference between series and parallel wiring? Please understand I am not trying to be patronizing, I am trying to clarify that we are all on the same page.

not the way you are asking it.
I'm with David on this one. Something in your last post is very confusing. The only way to get the same impedance load with the same speakers is if you use one or four drivers. There's no way of getting the same load with two. (you smart alecks leave that alone)
There are some drivers out there available in a range of impedances but you said these are the same. Please clarify this for us.
Here is my untechnical answer. If the load or inpedance is the same. No it is not harder on the amp at the same wattage output. When you run 1 sub on an amp you are more likely to lay off the volume as it starts to distort, for instance say the sub starts to distort at 60watts then you add two subs that sound good untill 60watts each now you are feeding 2 woofers 60watts for a total of 120watts. Now the amp is working harderthan it was with one sub.
