Ohms are very important, fyi. An ohm is a measurement of resistance, so an 8 ohm sub is twice as hard for an amp to push power through compared with a 4 ohm, so an amp can only push half as much power through an 8 ohm as compared with a 4 ohm. So the lower the ohm rating, the easier an amp can push power through it, but amps get hotter as they push more power and this is why you don't see many amps that are stable at 1 ohm or lower.216caddypimp said:The subwoofer looks like this one (I don't know what 4 Ohms or 8 Ohms is or what is the difference between the two) http://http://www.bestbuy.com/site/olspage.jsp?id=1069302879271&skuId=6252459&type=product&productCategoryId=cat03081
Another point is that if you hook 2 4 ohm subs in serial (in a series), they will have an 8 ohm load. If you hook 2 4 ohm subs in paralell, they will have a 2 ohm load. This is useful if you have a mono amp that's stable to 2 ohms, and 2 4 ohm subs (which is a very common setup, in fact I have this setup) or something similar.
