Does anyone even know how to do this the RIGHT away and explain it

well lets do this the easy way, its 2 sets of comps ( 4 pos neg sets) and a 4 channel amp, it doesnt take a genius figure it out, the simple way would be to put one to each channel.

and if you trying to run 4 sets in one car then only use 1 amp and wire each set to 2 ohms and put a set on each channel.

Is there any disadvantage to running 4 ohm speakers at 2 ohms?

 

[Phoenix Risen 10+ year member]

no there is not, the amp you have is 2 ohm stable it will handle that load just fine, it puts out 68 rms at 2 ohm so as long as your speakers can handle that youll be fine.

you know how to wire them at 2 ohms correct, not trying to insult just want to check so it gets done right

no actually i dont (no worries i dont take it personal haha).. i know all the basics and then some but the whole ohms law and working with ohms and pros and cons to it i dont understand... Different than running one component off one channel (+ to + and - to -)and so on?

to wire the comp sets at 2 ohms, you would have to wire the speakers to the crossovers as normal, then take the wires going into the input on the crossovers and wire the positive and neg of each set together, each set will then be on 1 channel of the amp, the only down side to this is that you will have 8 crossovers that you have to use, you could also wire each set of speakers to a single crossover, which would cut down the number of crossovers but it would put you at 4 ohms for each channel, which would lower the power a little,

where are the speakers giong and in what vehicle?
