4ohm or 2ohm for my setup?

[kungfoojesus 10+ year member]

Whats the difference between running 4ohm and 2ohm? Should I run an Alpine type R that needs 500W for 425W @ 4ohm or 800W @ 2ohm, with the gain properly set in either scenario of course?

Me id run at 4ohm to be safe...800W eh have fun w ur gains like literally at 0

it doesn't sound any different at what ohm you run it at. it all depends on your amp. if your amp makes enough power at 4 ohms then you want a dual 2 ohm, if it supplies proper power at 2ohm, you want dual 4 ohm.

Ohm is just a measurement of resistantce in an electrical circuit. So the higher the ohm rating, the harder it is for a current to flow freely through the circuit. There is no audible difference between ohm loads.

But, in your case, those Type R's have been known to take some power... I would run it at 2 ohms, and set the gain to put out around 600-700wRMS.
