How do I bridge my Stereo PA amplifier to run one 8 ohm Sub-Woofer?

Bridging two amplifier channels is a way of delivering more power to a single speaker. A two channel amplifier might have a power output of 100W per channel. By linking them together, the power output to the single speaker can increase to 200W. It's not always quite that simple. If the amplifier can be bridged, it will say so in the manual and it will show the connections that need to be used. Trying to bridge an amplifier that is unsuitable is a sure fire way of killing the amplifier and perhaps the speaker itself. There are certainly methods that can be used to bridge amplifier channels even if the manufacturer does not offer the facility. To do so needs an intimate knowledge of the electronics used in the amplifier. The fact that this question is being asked indicates that the required knowledge isn't there right now. Much safer to obtain an amplifier that is rated and approved for bridged loads than risk the unpleasant results of getting it wrong.

Is a 4 ohm subwoofer better then a 8 ohm subwoofer?
You need to match the speaker with the amplifier. Better or worse is not the question. The question is dynamic range and the possibility of overloading the amplifier. If the amplifier is rated 4 ohms, use a 4 ohm speaker. Same for 8 ohms. Do not "mix and match".
What will happen if you hook up a 2-Ohm Car Subwoofer to an 8-Ohm Home Receiver I have a Kicker Comp 12 2-Ohm Subwoofer so I was wondering if I could hook it up to my 8-Ohm Home Receiver HELP?
If your home receiver is not rated for a 2-ohm load (many can handle a 4-ohm, but not a 2-ohm), you will damage components inside the amplifier by over-current. Don't use car stereo components in home stereo equipment. It's like using a hockey helmet to ride a motorcycle.
Can you have a 2 ohm sub with a 4 ohm sub?
Yes, you can have a 2 ohm subwoofer and a 4 ohm subwoofer in the same system. However, it is important to match the impedance to avoid damaging your amplifier. You can wire them in series or parallel to achieve a compatible overall impedance for your amplifier.
Yes you can bridge this amplifier to a 2 channel at 4 ohm per channel for 200 watts out of each channel.?
Yes you can bridge this amplifier to a 2 channel at 4 ohm per channel for 200 watts out of each channel.
Will it not cause short circuit you wire 2 ohm amplifier to a 4 ohm subwoofer?
Sorry, but there is no 2 ohm amplifier on the market, when you mean the output impedance. The impedance is always 0.5 ohms or less. We don't use impedance matching, we use voltage bridging. Scroll down to related links and look at "Interconnection of two audio units - power amplifier and passive loudspeaker".
Can you replace subwoofer in 2000 Chevy Tahoe with aftermarket subwoofer?
Your SUV comes with a 8" subwoofer from the factory. Most likely a 4-ohm sub. I know the Kicker Comp VT 8" will bolt right in and you can get them either 2-ohm or 4-ohm. You would probably notice quite a difference putting a 2-ohm in.
Can you power 8 ohm speakers with a 4 ohm amplifier?
Yes, but you won't get rated pwer. Best is to match the speaker to the amplifier.
Can you use three 8 ohm speakers with one amplifier?
If the amplifier is designed for an 8 ohm load, then you should use an 8 ohm load. Three 8 ohm speaker in series is 24 ohms, and in parallel they are 2.67 ohms. Neither of those is a good match for an 8 ohm rated amplifier. If you do this, you will not achieve rated power, and you may well damage the amplifier.
What is better 4 ohm or 8 ohm amplifier?
Sorry, but there is really no 4 ohm or 8 ohm amplifier. We use only voltage bridging. Scroll down to related links and look at "Interconnection of two units".
What is 8 Ohms Stereo per channel?
Home stereo systems are usually built to work with speakers that have an impedance of 8 ohms, Car stereos are usually adapted to power 4 ohm speakers. You need to get this right if you want to keep your amplifier happy.
Can I safely run 4 x 4ohm speakers with an 8 ohm rated amplifier?
Not really. The only possible configurations of four 4 ohm speakers is 1 ohm, 4 ohms, and 16 ohms. This will not match an 8 ohm rated amplifier. It will work, but you will not achieve rated power output, and you run the risk of damaging the amplifier.
What ohm speaker is best?
take a 2 ohm bridge into 1 ohm
