FrankandBeans Unregistered guest | i have 2ALPINE SWR-1221D 12" TYPE R 300W do i need a amp that will give 600W to each subs, because of the dual coils, or just 300W per sub as stated on alpines website |

FrankandBeans Unregistered guest | i want to wire them in a 2ohm load because i have a mrd-m501 amps to power both of them, i would use option 2 on this page correct? http://www.crutchfieldadvisor.com/learningcenter/car/subwoofers_wiring.html?subs=2&impedance=DVC2x2 Also it shows one wire coming out of the amp going to to both woofers, how do you really wire that? |

Silver Member Username: GrmncrsnbrVA Post Number: 285 Registered: Jun-04 | that is correct and wiring isnt easy all connections between woofers should be inside the box. you would use one wire to make that connection it would be two and if im not mistaked the connects on the type R allow you to slide th wire through a hole and screw a peice down onto them in order to hold them so just put two wires in the hole. |

Silver Member Username: GrmncrsnbrVA Post Number: 292 Registered: Jun-04 | look at that picture. the amp goes where it says 2 ohms. or even better look at the 2 ohms like its the terminal on your box and all the wiring is done inside the box. the places where a wire goes in then comes back out just use two wiresone going in and one going out its not a hard concept to grasp dude. box terminal -------- wire one --------- speaker 1 terminal -------- wire two ---------- speaker 2 terminal |

sgw356 Unregistered guest | i know that the 2ohm is the amp, but i am wiring for two speakers, and there is only one wire coming out of the amp for both speakers??? do you stick two differnt speaker wires in the amp for both speakers? |
