New member Username: KitAustralia Post Number: 2 Registered: Mar-05 | i have a type r 12" 4 ohm DVC runnin off a M300 not 301!!! M300 (so people dont get confused) because theres like a 50 watt differnce between the 2 amps. the type r is 300watts rms so correct me if im wrong too say that i am runnin at 1/2 power because the sub is a 4ohm so its rated in the alpine catalog as 150 x 1 rms @ 4ohm 14.4v because i was told that i wasnt runnin 1/2 power but i dont see how i am? could someone plz explain this too me cause im new to this heres a site to see full specs on it BUT it says the rms power output at 4 ohms is 100watt so im confused?!?! http://www.epinions.com/Alpine_MRD_M300_V12_AccuClass_D_Mono_Amplifier__Mono_Sub woofers_MRD_M300/display_~full_specs |

Which means you cant wire that sub to a 4 ohm load. You can wire it in a 2 or 8 ohm load. Tell me how dfo you have the sub wire in the box. |

Silver Member Username: Addicted2bassMiami, FLORIDA USA Post Number: 425 Registered: Nov-04 | I dont think it does but ow do you have the sub wired in side of the box? |
|
New member Username: KitAustralia Post Number: 4 Registered: Mar-05 | sorry but i dont quite get ur question? its just runnin straight from the digital amp which drives the sub at a 2 ohm load |

Silver Member Username: Addicted2bassMiami, FLORIDA USA Post Number: 426 Registered: Nov-04 | Ok, since you're sub sub is a DVC sub the sub can't be wired at 4 0hm's it can only be wired at 2 ohms or 8 ohms? because in your first post you said the sub was running at 4 ohm's and it cant be. So i was asking how is your sub wired inside of the enlcousure because that would make a difference in the ohm load. |

New member Username: KitAustralia Post Number: 8 Registered: Mar-05 | 1 sub / Dual Voice Coil - 4 ohms x 2 Option #1 would be the one im pretty sure |
