YACT: Quick easy amplifier/sub wiring question.

[MarkW]

Ok, I have two subs, one amp. I am going to wire them in series/parallel to get a final 4 ohm load (dual 4 ohm voice coils on each sub). After wiring the subs, there are going to be 2 negative wires and 2 positive wires, but only 1 output of each on the amp (I am going to be bridging it). Ok, so how do I get those two wires in that one terminal?

How are you going to do both?

twist em together....put em in a fork (one of those -{ dealies ) and tighten the screw down?

YEah I read that and was like, "ARRUUHH??"

Duder, you obviously aren't too sure what you're doing. I suggest you stop, put down the subs, and rethink what you're trying to do before you break something.

read my link...to get 4 ohms out of 2 dual 4 ohm voice coils you have to use the series/parallel method....
although thinking about it more...since your bridging that means you have at least 2 channels....if u hook each sub in jsut parallel to each one of the channels that should give you 2 ohms on each chennel whcih since the bridge is giving you enough at 4 ohms sounds like shoulde give you plenty on 2 ohms on each channel...

drakkon thanks for the help man, so i just get both the negative speaker wires from the sub and just put it in that one negative terminal and tighten the screw down right? I can't believe i am even asking this since its a stupid question to ask. But as far as what all I am going to get, Vibe431 Amp, Amp Kit, 2 Image Dynamic IDQ12's. Just waitin for them to ship out


*edit* How to get the series/parallel connection, the subs are DUAL voice coil, which have two 4ohm voice coils each (regular subs only have one). wiring, scroll down to 2 DVC drivers with Voice Coils in Series / Parallel. Only question I had was you see that dot there when the wires come out of the sub? just wasn't sure how to connect those, I was afraid one sub would get more wattage than the other and what not. I was not really sure on how to do it, I kinda had an idea but I think it's been answered now.

So the way you are describing it would be the exact same thing I am doing now, right?

 

[Drakkon]

are you using the amp for other speakers? I'm kinda confused as to what your going for since your using a 4 channel amp...why not just a mono block and make everything 100x simplier

I think you got the right idea there so if channels 1/2 are your bridging ones...
subs -- ===== amp - from channel 1
subs ++ ===== amps + from channel 2

you can take the -- / ++ cables into one though mind you and just have one cable from +/- running to the amp...wattage balance wont be affected...cord length shouldn't matter unless your using really crappy wire which it dont look like...

Ok, sweet, so it is ++/-- on the amp. Reason why I am getting a 4 channel amp is mostly because of cost. I am gonig to be using channels 1/2 for fronts and 3/4 for subs. thanks for the help man, I really appreciate it.
