I have a rockford fosgate 1001d and 2 audiopipe dvc 12s need 2 know how wire speakers


Check to determine if your sub woofers are DVC 4OHM or DVC 2OHM SOLUTION 1 If your sub woofers are DVC 4OHM then, from the positive (+) of the amplifier run your cable to the positive terminal of voice coil 1 on sub woofer 1 then continue to connect all the positive voice coils together on both sub woofers. Do the same for the negative from amplifier to all the negative voice coils of both the sub woofers. RECAP: all positives together on the positives and all the negatives together on the negatives. This will give you a 1 OHM load to the amplifier making it deliver all its power but will also run hot. So if you are living in a hot climate take care. SOLUTION 2: Connect the negative on voice coil 1 to the positive of voice coil 2 on sub woofer 1 Do the same for subwoofer 2 now you should have a free negative and a free positive on each of the sub woofers. connect the free positives together and follow through to the positive on the amplifier. do the same for the free negatives sending them to the amplifiers negative. This will give you a 4 OHM load to the amplifier. Not full power in this mode but the most stable working condition for your amplifier. SOLUTION 3 If your sub woofers are DVC 2 OHM then you only have one reasonable wiring solution. Connect like solution 2. This time because of the DVC 2 OHM sub woofers you would have a 2 OHM load to the amplifier. This is also a stable load for the amplifier and does not generate to much heat and still deliver over 50% to 70% of the amplifiers power. good luck and drop me a line if you still have doubts. dreamsystems

How to connect HIFONICS BXI 2607 D watt at 1 ohm....


That's dependent on your subwoofers. You will need 2 dual 4 ohm subs wired in Parallel, a single dual 2 ohm subwoofer wired in parallel, a single dual .5 ohm wired in series. Or something similar.

Powers up but no speaker output


Hello montez1599,

That's a great amp.

You do not say what subs you are connecting or what wiring configuration you are using. But there should be no problem if the amp is powering up normally. I'd check the gain and crossover settings to make sure they match the subs.

Having 2 +'s and 2 -'s is just a convenience for connecting more than one sub to the amp. If you have just one sub, connect to either of the positives and either of the negatives (they're connected internally). If you have 2 subs, you can run separate wires to each sub or you can wire the subs together and then run just one positive and negative to the amp.

Hope this helps.

I have a PHOENIX GOLD RYVAL V1502 amplifier and trying to hook it up at 2 ohms as it describes it can be 450watts x2 at 2 ohms running wires from bridged positive and negative to the first sub then two...


Hello mgonzalez390,

It sounds like the amp/subs impedance is not matched. According to the published specifications for the V1502 amp, it is only stable in bridged mode down to 4ohms, not 2ohms. You need to get the final impedance that the amp sees up to at least 4ohms or it will continue to shut down and eventually fail completely.

If your subs are dual voice coil and can be rewired so that each sub has an impedance of 8ohms, then you can safely parallel them to the amp like you have described. If they are single 4ohm voice coils, then you have 2 choices. Connect one sub to each channel or if you want to bridge the channels, then wire the subs in series, not in parallel. Wire the positive bridged terminal from the amp to the first sub positive, connect a jumper from the negative of that sub to positive on the other sub, and then the negative from that sub back to the negative bridged terminal on the amp. This wiring results in an 8ohm load to the amp and it should work OK without shutting down. But the power to each sub will actually be less than if you wire them separately to each channel.

Hope this helps.

Need wireing diagram for hooking up two as12sq 12-inch square 2


you can run each sub at either 4ohms or 1ohm which means that two of them will run at either 2ohms or .5ohms....be careful how you wire them because most amps cannot handle .5ohms very well and might blow.....to wire them for 2ohms you will need to wire each sub the following way. they have two voice coils make a jumper wire connecting the negative on one coil to the positive on the other coil. what you are left with is a coil with an open positive and the other coil has an open negative. when both subs are wired like this connect the two positive terminals together (1 from each sub) and the two negative terminals together (1 from each sub) now the subs should be wired together at a 2ohm load. run the two positive wires into another combined wire which will run to the positive speaker terminal on the amp. do the same for the negatives

How do i hook it up


On the Sub you have 4 connectors, 2 for each voice coil... Run a jumper wire from One side of the sub to the other. Positive to negative so that now you have one set of connectors free. Doing this will make the sub able to handle more cause you're using both voice coils. Thats how i've always hooked mine up when i have duel voice coil and they always last a long time. If you're gonna bridge the amp, make sure its turned down for about 5 or 6 hours to let the sub break in.

Trying to wire my amp to my subs


no thats not it you are lucky you havent burned it up like that. wire each speaker to its own source positive and negative, you loose power when you bridge an amp and use two speakers, its best to hook up without bridging you will get more volume that way.

Subwoofer help


hard to tell whats causing this .Just curious make sure speaker wires going to subs are POLARIZED meaning positive from amp is with positive at woofer and NEGATIVE is with negative at woofer.When these are crossed and when volume is raised you will hear the bass cancell each other out..
