How to bridge Jensen a 220 amp says not to hook negative s together

You will have to wire subs together for a 4 ohm load. Then bridge amp (1 channel). Look on amp speaker outs to see what leads to use to bridge. Run positive and negative to one speaker then use a jumper wire from that positive and negative to the next speakers positive and negative

Pace posted on Saturday, March 05, 2005 - 01:08 GMT Your subs are dual 4 ohm voice coils so if you want to bridge your 2 channel amplifier to your two subs then wire them parallel, meaning the + to + and - to - ( Do this to both subwoofers), Then run a wire from one positive and one negative on each sub and bring the two positives together and the two negatives together and hook both positives to the far positive connection on your amp and connect both negatives to the other negative on your amp,

This will create a 4 ohm load on your amp.

Although if it's a two channel and you have two subs it's usually pointless to bridge them because if you use one channel per subwoofer its going to be the same as if both subs were bridged. example) 800 watts x 1 bridged power of your amplifie (4 ohms) is the same power as 400 watts x 2 at 2 ohms.

Hello... I can help you with this question. Yes it is possible to do this, but you will have to use a 2 ohm stable mono block amplifier in order to do this. By connecting both positives together and both negatives together, you will be running a 2 ohm load. So if your amp is a monoblock amp, connections will be simple as tieing all the positives together and the negatives together and just hook to the amp. If you are using a 2 channel amplifier that is bridgeable, then you will need to series the subwoofers to an 8 ohm load and then bridge the amplifier to 1 channel. The way you series the subwoofers is take the positive wire in the box and hook to the positive on subwoofer #1. Take the negative wire in the box and hook to the negative on subwoofer #2. Then take a piece of wire and hook the negative from subwoofer #1 to the positive connector on subwoofer #2. Then hook the wires to the amplifier. To bridge the amplifier (if it is a 2 channel bridgeable) would be to use the left positive and the right negative, but check the amplifier for markings to confirm this. If you have any other questions, feel free to let me know and I will help you out! Hope this helps!!

To bridge an amp, connect the negative speaker lead of a speaker to the negative terminal of the first channel, and the positive speaker lead of the SAME speaker to the positive terminal of the second channel.

If your subs are dual voice coil, they will be tricky if you're not familiar with them. If you wire them in series ( a black and red together) and bridging them on the amp, you might be overloading the amp if it is not capable to handle it ( 1 ohm stable). Instead of bridging, try parallel series on the amp. A positive and negative will be wired together. The other postive will go to the positive of channel 1 and negative to the negative of chanel 2.

Or wire the speaker in parallel ( black with black- red with red) and you can then either bridge them on the amp or on their own channel

Easy, you grab a dual wire cable (like the one in the back of your amp that runs to the speaker) and stick each wire on one end to the positives on your amp. Then, on the other end, twist both wires together to form one wire. Hook it into your positive connection on the sub(s). Repeat on negative side.

put a positive from the left sub in the positive slot then put the negative from the right sub and put it in the negative slot the take the other positive and negative and twist them together and cap them off.

your speakers are hooked up wrong. hook both positives together and both negatives together and bridge it to the amp. if it is one channel hook it up as one together. if it is 2 channel hook positive to one side and negative to the other side.

hi .let me see if i can help u out ...need more info on the speaker..are the 8ohm or 4ohm ? and are the single are DVC?.....from what i can see u can bridged the amp..and u must connet the subs in series or just connet each sub +/- to +/-..and that will give u a stereo mode... u will still get great sound

if you are talking about speaker terminals i would have to know the model you are referring to. take a look at where the speakers hook up, you should have +-+- if it is bridgeable it will usually have markings below or above those that only show 1 + and 1 - ... connect your positive to the single specified and negative to the other specified... you may or may not be able to bridge it with a wire, without the amp model, i can not say for sure...

if you are talking about actual power connections, then yes you can bridge them, i have an old amp here that has 1 remote, 2 positives and a large negative.. i bridged the positives using 6 gauge wire and used a 2 gauge for the negative...

hope this helps,
