possible to bridge 2 speakers to one amp?
i been wondering if you can bridge 2 subs to one 2 channel amp? cause i got two DVC subs that are 400 watts RMS and if i bridge my amp it puts out 800 watts RMS. my cousin said that you can only bridge one 2 channel amp to one sub. so answers to this would be appreciated
You could do that, but you would have to wire the subs to 8 ohms (if they are 4ohm DVC) so that it will be configured for a 4 ohm setup. If you don't you are going to wire it for a 1 ohm setup and your amp will not work like that and will go into protection mode everytime the bass hits or blow a fuse everytime.
You can put any number of speakers on an amp, what is important is the load. [impedance the amp "sees"] and the power handling of the speakers and the RMS power of the amp.
What is the make and model of the amp and speakers?

hey guys thanks for the replies. well the subs are audiobahns i forgot which models but its a 4 ohm dvc and 400 watts RMS and the amp is thos old school rockford fosgate amps. so if i were to bridge the amp how would i wire the speaker wire to the amp? do i just connect both the speaker wires from the sub to the amp?
ok so i checked the amp its a rockford fosgate punch 800a2. on the bottoms it says 200 watts rms into 4 ohms and 400 watts rms into 2 ohms. it said to refer to the user manuals on how to bridge it. this is the right way to wire it right? http://www.crutchfieldadvisor....VC4x2 so that way i get 200 watts rms into both so subs so that means im getting 400 watts rms total? someone correct me if im wrong cause i still get kinda confused sometimes lol
Wire the 2 coils of each sub in parallel, and then connect each sub to its own channel. Or you could use crutchfield picture #2 and connect the subs for a 4 ohm load and bridge the amp. Either way, you will get the same power output. So I'd say, run it as a 2 channel, not bridged.

but my amp says when its bridge at 4 ohms i get 800 watts rms versus just having 200 wats rms or am i misunderstanding something here
or am i able to wire each individual sub to 2ohm each and get 400 watts rms into each subs without messin up my amp? im still kinda new to these kinda things

Do the math.
400 watts x2 (at 2 ohms) = 800 watts total.
800 watts x1 (at 4 ohms, bridged) = 800 watts total.
If you go with 2 separate channels, each sub will be wired for 2 ohms, which means each will get 400 watts from the amp. If you go bridged, you'll have to wire the subs for 4 ohms, and then you will get 800 watts from the amp, but since that is powering both subs, each sub will get 400 watts. As I already said, either way you get the same power output. To answer your question, yes, you can wire each sub for 2 ohms and not damage the amp.

Wire the VCs on each sub in series then wire the subs in parallel http://www.the12volt.com/carau...s.asp use option 2, [4 ohm load] then bridge amp into mono... http://www.rockfordfosgate.com...81892 page 16.

so how about this link i posted? http://www.crutchfieldadvisor....VC4x2 does that refer to mono amps only? cause i see the wires only going to one amp or whatever
so that means i can wire each of my dvc subs to 2ohms each. and hook it up to each channel of the 2 channel amp and the amp is gonna see a 2 ohm load on each channel right? whats series and parralel the link you posted doesnt work.

^^^^^^ This is the best advice that you are going to get. You are going to wire the vc of each sub in series. Your first sub- neg lead to the positive lead. This is going to leave you with a extra neg and pos, Now that sub is 8 ohm. Do the same for the other one. Now you have two 8 ohm subs that are just dying to become a 4 ohm sub. Now you are going to take the positive from each sub and the neg from each sub and bam, a four ohm load has appeared. Do you understand now? This is called series-parrellel wirering. Now connect it to your amp as the instructions say and your done.
oyea left positive off the amp is going to go to the positive for your subs. And right negitive is going to go to the negitive of the sub.

how this method? would this be the same as bridging the amp? and do i just twist the wires from sub 1 with sub 2 and just put it into the described input in the manual to bridge it?

i have two 10" rockford subs they are 4ohm dvc subs. i have a rockform amp which is a 2 channel amp capable of holding a 2 ohm load i wired each speaker like this which pulls the most power from my amp and keeps the load correct

wire each sub like this to each channel on you amp, dont worry about bridging the amp

ohh ok thanks so much now i get it more. cause i get confused when people talk about serious parallel and all that other stuff. thanks alot man i just wired iti like that and i can tell that my subs are a bit louder. some songs sound better and i had to turn down my subs a bit
i dont gotta worry about my amp blowing do i? cause it seems to be runnin a lil hotter. i always though that if you wire the 4 ohm dvc subs to 2 ohms each i thought you always had to divide by 2 or something and thats the ohm you get. so i guess i really misunderstood. i guess those wiring diagrams are for like 2 subs into a mono amp? the ones on crutchfield and everywhere else

and btw i got the old school fosgate amp 800a2 transana or smoething and iwas wondering what do you use to set the gains. cause when my uncle gave it to me theres no **** on the gains. i tried to use a small screwdriver but its kinda hard. can someone enlighten me? pleease?
i havent set my amp either. you might want to lookaround on http://www.the12volt.com or http://www.caraudio.com

The amp was designed to be bridged into a 4 ohm mono load, the subs can be wired to a 4 ohm load, a series/parallel wiring of the subs and bridging the amp is the best possible way to wire/connect the subs to that amp.
Although there are more then a couple ways to wire amp and subs, some that will work,, [but not get the most out of the am] some that will work, [but can damage the amp and/or the subs] but there is only one BESTway, and a series/parallel wiring of the subs and bridging the amp, IMO is the best way.
And yes, you must set the gains, a small flat head screwdriver, ["jewelers"] is needed, not using the proper screwdriver can damage the gain controls, and on that amp you must be careful not to "bend" the control over, [not hard to do on that amp]

Go here... http://www.the12volt.com/carau...s.asp select "2 speakers" and then "4 ohm dual voice coils" then "view wiring options" scroll down to option 2. wire like that and bridge the amp... http://www.rockfordfosgate.com...81892 page 16.

Drill a hole, or wire them together outside the box, run both speaker leads to the amp and connect both pos.(+) to one terminal and both the neg.(-) to the other terminal, [bridged wiring].

ohhh ok now i get it i always thought you just twist'em the speaker wires from each sub together or something.if i drilled a hole wouldnt that affect the chamber in anyway?and how would i wire them together outside of the box?
