Bronze Member Username: SuicidejackPost Number: 30 Registered: Jul-05 | im confused and need a visual in how to wire (2) QVC's to present a 4 ohm load on my amp, i just want to make sure im doing the right thing, i know putting one sub in series will present a 8 ohm load and if i present both 8ohm loads, thatll give 4 ohms to the amps right? KILLa helped me a lil but now im confused cuz this diagram looks parallel https://www.ecoustics.com/electronics/forum/car-audio/277720.html the professional installer in my town has never seen a QVC's so i think he jacked up the wiring. i sent for replacement amps twice i think he loaded both to a .25ohms to a soundstream picasso pca3500 |

Gold Member Username: TjmutlowPost Number: 3024 Registered: Sep-05 | those are quad 2, so if you wire a pair of voice coils series to get a 4 ohm load, then wire the other pair to get 4 ohm load, the wire the 2 pairs series to get an 8 ohm load, do the same for the other sub,(you should have 1 wire that would go out to the terminal per sub) wire those parale to get a 4 ohm load. |

Gold Member Username: TjmutlowPost Number: 3025 Registered: Sep-05 | your right, confused even myself, run + to -(series) vc1 run + to - on vc2, vc1 run - to + on vc2, vc2 run + to - on vc3, vc2 - to + on vc3, vc3 + to - vc4, vc3 - to vc4 +, then 1 wire to teminal comming off any voice coil(+, -) do the same for other sub, then take 2 wires and run + to +, - to - to get 4 ohm load, I would draw it but I do not know how to do that on the computer... |

Gold Member Username: SouthernrebelMonroe, Louisiana USA Post Number: 3540 Registered: Mar-04 | think of it like this...wiring wise, you have the same thing at four DVC 2ohm subs. Take this diagram and look at it like there is just 1 sub w/ 4 VC's.  Wire each subs like that, then wire the subs parrallel. |

Bronze Member Username: SuicidejackPost Number: 33 Registered: Jul-05 | some one was telling me that running 1250 watts per sub(12"re sx) would be ok for daily driving, so now i was considering a 2 ohm load. wanted to go on the safe side and run 900 watts but if hes right 2500 for both sounds better. damn went through all this trouble going all 4 ohm even 3 ohms is ok. someone on this thread named QCSfinest gave me the perfect diagram, i was already using KILLa's diagram, i thank you Kila, and everyone who chipped in to help an overly cautious person. THANKS!!!! |
