Question about Alphasonik Mayhem PSW912 Car Subwoofer

Problem is one of four things:

- Impedance (ohm resistance) of the speakers you are using is below the amplifier's rating for operating in bridge mode;
- You are driving the speakers at a volume exceeding the maximum power output of the amplifier;
- The gauge of the wires you are using to connect the amplifier to the speakers is too small;
- The gauge of the power supply wires is too small, and/or you are not using a large enough reserve capacitor at the power input

- If your Kicker subs are rated at 4 Ohms, and you are using them in monoblock configuration with the speakers wired in parallel (all + terminals to the + bridge output and all - terminals to the - bridge output), try either configuring your bridge circuit in a paired bridge, where a pair of amplifier outputs are bridged, each bridged pair driving a single speaker; or if your Kicker subs are rated at 2 Ohms, use a monoblock bridge driving the speakers in series (+ bridge output to + of one speaker, - of that speaker connected to the + of the other speaker, and = of that speaker connected to - of the bridge output);
- Turn the amplifier output down (but this is likely NOT the issue)
- Use speaker wire that is no smaller than 8 gauge for your application. 4 or 2 gauge wire would be slightly better but not worth the additional expense;
- Your power supply wire should be equal in size or larger than your speaker connector wire. Use no smaller than 8 gauge for your application. Also, use a capacitor no smaller than 2 Farads wired across the power supply input to the amplifier to compensate for pulse surges and car power dips. For your application a large capacitor will work better than an auxiliary battery or gel cell.

If there is no red and black colored input wire connectors on the subs then it doesn't matter.Positive and negative does not really effect speakers and subs since it is DC anyways.

Connecting the speakers in parallel is the best route here. Parallel wiring is simply connecting the positive wires together and connecting the negative wires together. Then connect both positive wires to the positive output of the amp and both negative wires to the negative output of the amp. When both 4ohm speaker are connected in parallel the combined impedance is 2ohms. This particular amplifier has a damping ratio of >250 at 2 ohms compared to a damping ratio of >1000 if you connected them in series at 8 ohms. the damping ratio is simply the reduction of power transferred. (For future reference in order to get the maximum power transfer input impedance must match the output impedance.)

Yes audiobahn do make a QUAD coil, and some people get confused with the - - + + on the terminal, This is called a dual lug, Check out Audiobahn.com and go to tech suport. Thier you can look up the wiring diagram for this sub... TRUST ME hope this was helpful positive feed back be nice lol

If they are single voice coil speakers (1 positive and 1 negative terminal on each speaker) then connect from amps' Positive output terminal to spkr. 1 positive terminal, THEN spkr. 1 neg. terminal to spkr. 2 positive terminal, THEN spkr. 2 negative terminal to spkr. 3 positive terminal, THEN spkr. 3 negative terminal to amps' negative output terminal.

That is 3 speakers wired in series. if each spkr is 2ohms, then you will have a total 6 ohm load. If 4 ohm spkrs., then a total 12 ohm load, if 8 ohm spkr., then a total 24 ohm load.

Be careful because amps do not like these odd ohm load totals. You might get away with a 6 ohm total load. Depends on the amp.

Ohms is an impedance, they call it resistance. You have to hook up 8 ohm speakers to the 8 ohm terminals on your device. Some speakers are 4 ohms, and may not be able to handle the power if hooked to 8 ohm terminals, so be sure you have what they call an "impedance" match.

Watts, by the way, is what they measure Power by, and P=EI (Power equals voltage times current).

+ output from amp to + input of 4 ohm to + input of 8 ohm AND - output from amp to - input of 4 ohm to - input of 8 ohm is a parallel circuit = 2.66 ohm impedance load for amp

+ output from amp to + on 4 ohm - on 4 ohm to + on 8 ohm - on 8 ohm to - of power amp is a series circuit = 12 ohm impedance load for amp. Clear as mud??

Are these Dual Voicecoil Subwoofers? Are there 4 terminals on each sub for wires?

If they are Dual 4 ohm voicecoil subwoofers

- connect both + on subwoofer 1

- connect both - on subwoofer 2

- connect both + on subwoofer 2

- connect both - on subwoofer 1

This will give you a 2 ohm STEREO load.

To get a 1 ohm MONO load...

now connect only one of the + on EACH sub to the + on the amplifier.

and the - on EACH sub to the - on the amplifier.

You now have a 1 ohm mono load.

If your speakers are 4ohm single voicecoils (one pair of terminals) the lowest impedence possible is 2 ohms.

This is wired in the same fashion. Both + on the subwoofers to the + on the amp, and both - on the subwoofers to the - on the amp.

WELL FIRST IF THEY ARE DUAL VOICE COILS, IF SO,TO GET 2 OHMS JUS THOOK THEM UP TO ONE OF THE TWO TERMINALS, IF YOU WANT 4 OHMS HOOK YOUR POWER LEAD TO ONE TERMINAL THEN ABOUT THREE FEET OF WIRE COMING FROM YOUR LEAD TO THE O9THER TERMINAL, IF YOU WANT 8 OHMSHOOK YOUR POWER LEAD TO + ON ONE SIDE THEN THE NEGITIVE LEAD TO THE - ON THE OTHER SIDE, THEN VISE VERSA. BUT IF I WHERE YOU MAKE THEM 4 OHMS

GOOD LUCK

Accommodating the rising trend of triple-subwoofer applications, Audiobahn’s Sound Q subwoofers come in dual 6-ohm configurations. This allows three Sound Q subwoofers to be wired in a 1- or 4-ohm operation. You now have the option to use a wider range of amplifiers to fit the needs of your specific application.

Audiobahn’s patented Multi-Connect Lug Lock Terminals offer increased versatility in wiring multiple subwoofers to an amplifier or to another voice coil. Multi-connect terminals allow you to use single wire connections in each terminal rather than combining multiple wires into one terminal. This feature allows you to use a full 8-gauge wire in each terminal.

Dual 6 Ohm VOICE COIL

The Link below should answer all your questions.

Also remember to try to keep the lengths of the jumpers the same. I would make all the connections inside the box then use the teminal block of the box to connect to the amp.

Keep in mind that you can only get 1 Ohm if you use 3 woofers.

Your configuration allows for 1.5 Ohm
