JustAQ Unregistered guest | Sorry Im so stupid with these things, but Im trying to bridge my amp, and made a little diagram. http://img.photobucket.com/albums/v313/WankstaW/AmpWire.jpg This would work right? The + and - are voice coils. |

Does it support bridging? If so, what is the minimum requirements? If you exceed that, then your amp will either overheat or burn out. |

JustAQ Unregistered guest | Theres 2 subs, they are DVC and 4 ohms. I have a A2X400HQ, and it does support bridging (correct me if Im wrong), and I dont know the min. requirements. |

For 4ohms mode: Wire each VC in parallel to itself. That is, pos to pos and neg to neg. Now do the same on your 2nd sub. This should make each sub, 2ohms in resistance. Now take the pos from sub 1 and connect it to neg on sub 2. Then using the other free connectors (neg from sub1 and pos from sub2), attach them to the amp. On the amp, it should have some kind of info on which terminal to use in bridged mode. For 1ohm configuration (parallel): Repeat the above wiring on the subs. However, instead of connecting pos to neg, you pair them up. Take the pos from sub1 and connect it to the pos on the 2nd sub, do the same for neg. Now you should have 1ohm resistance. Take the pos and neg from the subs and connect them to the amp. For best SQ, operate the amp in 4ohm mode. |

JustAQ Unregistered guest | Alright, so I was right about the 1 ohm configuration. At 4 ohms, it will only be putting out 400 rms... What if I dont bridge it, and just run it at 1 ohm stereo? What do you think about that? |

Gold Member Username: CarguyPost Number: 3777 Registered: Nov-04 | You can't. 2 4ohms DVC will give you 8ohms, 4ohms or 1ohm configuration. If you wanted to operate in stereo mode, then you can do 400w x 2. For max power, you need to bridge the amp and use 1ohms. |

Dan_Harper Unregistered guest | You can't run a 1 ohm stereo with 4 ohm DVC subs. The lowest you can go on each sub is 2 ohm. This would give you 400 watts to each sub. This would be the way I would set it up. |
|
JustAQ Unregistered guest | Alright I see, thanks for the help then, Ill think about it. |
|
JustAQ Unregistered guest | Ok wait, how would I wire it to get 400 x 2? |
|
JustAQ Unregistered guest | Or wait, is it like the first one you described? |
