yes all u have to do is bridge them together
Left positive to positive on speaker Right negative to negative on speaker
3 passive sub at 8 ohm imp in parralel will be 2.6+ impedence.Most of the professional sum amp can take up to 2 ohms load per channel(check the spec of the Amp)eg: you should be able to connect max 4 subs in each channel(match the watts pwr to amp)
a channel refers to the speakers or subs. for example a 2 channel amp can power 2 subs or speakers. a 4 channel will power 4.
u can bridge it to 2 channels not one to make it a mono block
If you bridge a 2 channel 4 channel ect. you are taking the power from both channels as if it was a single channel amp.
well if its a 2 channel then 1 pair of subs like if it has only one red and one white connecters then only one pair of subs then if it has 2 of each then 2 pairs of subs that's called a 4 channel amp seacrh in Google 4 channel amp and 2 channel amp you'll see what am talking about see look http://akamaipix.crutchfield.com/ca/learningcenter/car/subwoofer_wiring/4DVC_4-ohm_4ch.jpg
Type in google 'subwoofer wiring' and click on the 'crutchfield' link. Really good diagrams on how to connect dvc subs and svc subs to any amp.
Run a 2 sub per amp set-up. Get a distribution block for you power wire to split the power wire. You can run the remote wire from your stereo to one amp and then from the amp to the other amp. you will also need 2 sets of RCA's Easy way is too get a 4 channel amp to power 4 subs.
No
To bridge your amp you have to first look at your amp,find the speaker hook ups and it should say either on the top or the bottom [-------------bridge------------------]- + - +- +- +- after you find this you will have to run two sub woofers or one duel voice coil speaker to the positive side and one to the negative side of the bridge on your amp,you will connect the two positives of the two subs together and hook up to the positive side of the bridge and then the two negatives of the subs together to the negative side of the bridge,that will bridge your amp and speakers.Make sure that your amp can handle the new load, if it can't ,then it will start to cycle on and off.If that happens just run in stereo,not bridge mode.(Some amps will have a switch that you have to press to make it run in bridge)
A 2 channel 900w per channel amp or less will run it, or a 1800w one channel amp etc.. Keep in mind the ohms need to match up too
