munkee Unregistered guest | I have 2 Audiobahn AW1251T 12" 400 watt RMS Subwoofers and 2 XM-D400P5 Mono Class D Amps to run them. The amp specs are: 200 w RMS x 1 at 4 ohms 400 w RMS x 1 at 2 ohms So i guess i need to run the subs at 2 ohms each to give them the full 400 watts RMS power????? If anyone could show me how to wire this up to get the best out of the subs that would be a great help!! (im gonna have the two subs monted upside down so that you can see the bak of the sub where the magnet is... if that makes a difference?) With all this, wud it be a good idea to have a power cap?? If so, wot rating?? |

munkee Unregistered guest | The specs of the subs are: 800-watts MAX Power Handling 400-watts R.M.S. Power Handling 2" four Layer Black Aluminum Voice Coil Nice Dual 4 Ohm Voice Coils 2 Ohm or 8 Ohm Operation Each one So you recon having a power cap wont make any bit of difference?? thanx GlassWolf |

munkee Unregistered guest | sorry to be a pain but do you have a diagram to show how you "wire the coils in parallel" as i am not too sure what this means Thanks again... You really know your stuff! |

munkee Unregistered guest | Thanks for the link but they only explain wiring with 1 amp. I have done a quick diagram, please could you take a look and let me know if its right: http://www.trustphotosite.com/adamglenis/SUBS/ Thanks again! |

Gold Member Username: GlasswolfNorthWest, Michigan USA Post Number: 2195 Registered: Dec-03 | yeah you wire one 4+4 DVC sub to one amp. then do it again with the other amp. then use a single 4AWG power cable from the battery to the amps' location, and split there with a distribution block and run 8AWG line to each amp and ground with the same 8AWG. and no your pic is wrong the coils are bridged + to + and - to - then wire the one pair of + and - from amp tp sob. |

munkee Unregistered guest | so is this more like it? http://www.trustphotosite.com/adamglenis/SUBS/ Sorry for all the Q's |

|
munkee Unregistered guest | Thats great thanks!! So using this wire setup in that diagram will run both the subs at their 400 watts RMS each? That is my final question :-) Thank you so much for your help! really appreciate it!!! |

|
munkee Unregistered guest | maybe... but they look cool...LOL If i was gonna have 1, where would i wire it in? Would it be wetween the battery and distribution block? thanks |

Gold Member Username: GlasswolfNorthWest, Michigan USA Post Number: 2212 Registered: Dec-03 | most subs are offered in several versions, DVC 2+2 and 4+4 or DVC 4+4 and SVC 4 ohm this gives you multiple ways to wire one or more subs depending on the amp(s) you choose so you can match subs and amps for an ideal power output. there's no difference in performance. the capacitor would go just before or just after the distribution block near the amp(s) usually wired into one of the positive nodes of the block as a "pass through" and grounded where the amp is grounded so the capacitor is in "parallel" with the amp. |
