New member Username: Slayer77None, None non Nnoneoneone Post Number: 3 Registered: Jul-04 | I have a an electronic question. I need to wire 2*12" 4 ohms subwoofers on my 4 ohms bridged amp. Is there a way to this with a combination of a series and parallel wiring? This is way over my heard. I do not wish to run in 2 ohms or 8 ohms. My amp pumps more juice when it is bridged in 4 ohm. http://www.rockfordfosgate.com/rftech/wiringwizard/4_4ohmSVC_4ohm.gif Something like this but with 2 subs. I really can't figure it out. Is this even possible? Phil |

So 4 cables to the amp. 1 in each slot. making it hmm 2 ohm stable. Here are my amp stats: Peak Power Per Channel @ 2 ohm 170x4 RMS Power Per Channel @ 4 ohm 60x4 RMS Power Per Channel @ 2 ohm 85x4 Peak Power Bridged @ 4 ohm 340x2 Peak Power Per Channel @ 4 ohm 120x4 RMS Power Bridged @ 4 ohm 170x2 http://www.jensen.com/car_electronics.aspx?ProductID=90&SubCategoryID=2&Category ID=1 Subs are 2*12" 250W RMS/500W Peak each. I just want this to run low without arming any component. Subs are 4 ohms Phoenix Gold XS Series. Awaiting my 900W RMS Amp. Meanwhile surviving with this. |

Silver Member Username: Davids2004Houston, TX USA Post Number: 280 Registered: Jun-04 | From your specs you have a 4 channel amp. Bridge one sub to channel 1-2 and bridge one sub to channel 3-4 giving each sub 170 watts rms. |

Except that If I switch to 2 or 4 channels on the amp, the subs still work. I have the option of 2, 3,4 channels. Why do both subs work in 2 channel mode? When they are each bridged on 2 separate channel? How should I set it up? Everything works either in 2 channel or 4 channel mode. I do not understand why. |

Silver Member Username: Davids2004Houston, TX USA Post Number: 296 Registered: Jun-04 | Maybe it works because the amp is seeing the bridged subs as only using 2 channels. I could be wrong though which Im sure I am. IMO i would keep it on 4 channel though. |
