I know stuff all bout ohms these are the figures of my amp

RMS Power 4-Ohm Bridged: 2x400
RMS Power 2-Ohm Stereo: 4x240
RMS Power 4-ohm stereo: 4x130

i got a 12" sub and two 6" that i want to run of the amp just wondering how id get them to run as much power as the amp can supply is it to do with ohms on the speakers or wat ? im very confussed about it all

Bridge the sub,
Wire the left and right speakers straight up.

Thing with using amps. Bridged gets more power yet loses control to a degree, so don't think the more you milk out of it the better. Plus the more strain you put on it the more chances of it dying if it's poorly built.

heres a website i found that could be very usefull to every audio noob like me.....
