[QUOTE="Heeltoeclutch, post: 7294760, member: 629974"] Alrighty lovely - so these should be your subs. [URL="http://www.crutchfield.com/S-usL2npruIHJ/p_1081250W/Infinity-Reference-1250w.html"]Infinity Reference 1250w 12" 4-ohm subwoofer at Crutchfield.com[/URL] It says that they take 300 RMS, so you will want at least a 600W amp to power these subs. Every sub has an "impedance," and these are 4-ohm subs. The impedance will affect how much power goes to the subs from an amp. Very generally speaking if you half the impedance the amp sees, you double the power it puts out (if the amp can handle that impedance). If an amp will produce 200W given a 4-ohm load, you can predict that it will produce around 400W given a 2-ohm load. If you were to wire these subs in parallel, the amp would see a 2 ohm load. So you will want to look for an amp that will do at least 600W RMS at 2 ohms. [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] Making sense?
