Wiring 2 subwoofers to a mono amp?

I was just given a Rockford Fosgate 250m mono amp and two 10" Kenwood 300w subs in a bandpass box. I know the 2 subs where wired to the same amp but I dont know how to wire it. Any help is great.

Re: Wiring 2 subwoofers to a mono amp?

The subs can be wired "parralel" or in a "series". it depends on the ohm rating of the speakers and the amp. Most amps can only go down to 2ohms (mono) so it depending on the ohm ratings of the speakers when wired in a series vs parralel that will decide how to wire them. you can always take the safe route and just wire the positives of each to positive on the amp and the negatives to the negatives on the speaker terminals. Do you have the speakers model numbers?

you cooked the coil in the sub when you see smoke you have clipped the sub. improper wiring probably the issue ohms must match gain must be set properly . if you had gain all the way up thats what did it.

Rockford Punch HE2 wiring question.

if your sub will handle it, bridging it will give you more power. The best thing to do is to find out how much power the amp puts out ( RMS ) and if it is in your power handling range bridge it. It sounds better and gives you a harder punch because of more power.

You may be surprised to learn that even though there is a negative and positive on the sub it usually dont matter all that much because that amp allows you to switch the polarity of its outputs to allow your mids to sound better... anyways on to your question To wire a sub it depends on how many you have, if they are dual or single voice coils, what impediance your amp is stable at. Tell me what type of amp you are hooking this subwoofer up to and how many are being connected. And ill try and give you the best way to connect the sub(s) to your amp.
