Ok so today my buddy came over and he knows a pretty good amount about car audio and i thought my JBL amp was a mono channel but he told me that it was a two channel because it had 4 outputs and i was plannin on buying two 12 type r's dual 2 ohm but now that i realized that my amp is a two channel and the channels will need to be bridged does this mean that i will need to get the dual 4ohms or does this matter will someone explain this to me.
yes its a mono amp which puts out 1200 watts at 2 ohms and at 1 ohm. Thats a nice amp by the way. JBL doesn't make them like that any more. You can get either the dual 4 ohms and run them at 1 ohm or the dual 2 ohms and run them at 2 ohms is your choice.
it doesn't matter. I would get the dual 4's and run it at 1 ohm off that amp and if you decide to do just 1 later you can run it at 2 ohms, or run them both at 4 ohms off another amp. I would do the dual 4's
that amp puts out the SAME amount of power at 2 ohms as it does at 1 ohm. It draws the same amount of current at 1 ohm as it does at 2 ohms. It will get just as hot at 1 ohm as it does at 2 ohms. I think this should clear things up.
