How to bridge a dual voice coil at 2 ohms?

Question

bridge jl audio dual voice coil @ 2 ohms

Answer 1

on the speaker you'll see two sets of leads. 1- + POS/- NEG and another + POS/- NEG. use the + POS on one side and the - NEG on the other side. then, using a jumper wire of sutible gage,  jump the remaing + POS on the one side and the other - NEG. from the other together. hook up your output wires, from your bridged amp, to the proper polarity.

Answer 2

First of all the sub will be designed so that each voice coil has a certain ohm rating, for example it could be a dual voice coil with each coil at 2 ohms. Or it could be a d.v.c. with each coil at 4 ohms. This will determine what the final load of resistance is going to be that your amp sees. No matter what the ohms of your voice coils, if you wire them in series, the final ohm load the amp sees is (voice coil 1 impedance + voice coil 2 impedance.)  For example, if you have a d.v.c. sub with 2 ohm voice coils, and wire it in series your amp will see a 4 ohm load. If you wire the sub in parallel, the final ohm load will be half of one voice coils impedance. For example, a d.v.c. 2 ohm sub wired in parallel will bring the impedance the amp sees down to 1 ohm. Wiring in series means that you connect the postive signal wire from your amp to the positive connection on voice coil 1, and the negative signal wire from your amp to the negative connection on voice coil 2. You then connect the positve from voice coil 2 and the negative from voice coil 1 together, and your sub is wired in series. To wire in parallel you must run the positive signal from the amp to positive on voice coil 1. The negative from the amp to the negative on voice coil 1. Then connect the positive from voice coil 1 to the positive on voice coil 2, and the negative from voice coil 1 to the negative on voice coil 2. You amplifier should determine what ohm load you want to create with your voice coils. If your amp produces 300w@4ohm and 1200w@1ohm you would probably be best wiring your sub in parallel to get the full 1200w. Be sure to check and MAKE SURE that your amp can handle a 1ohm load. The less the ohms, the less resistance, and the more power. It is often the case that an amp will go into protect mode or thermal shutdown if ran at a lower ohm rating than it is designed for. Check your amp specs and search google for series and parallel wiring if you need a diagram. If your amp is a single channel amp you should not need to bridge your amp. If it is a dual channel amp you should be able to run a wire from the positive on channel 1 to your sub, and a wire from the negative on channel 2 to your sub, bridging the power of the two channels together. If your amp is a 4 channel it can only be bridged to 2 channels. Your amp should have a diagram on how to bridge it if it is a multichannel amp.
