48/14 = 3.43 Ohms (rounded), You can also use an impedance calculator such as this one. Eitel's health blog, PromoteHealth.info, has become an authority in the healthy-living niche. Since your amp does not have an RCA output for the sub you best option is to put the sub in parallel to the speakers. So cut 2 lengths of speaker cable for each side (left and right). Your amp is rated at 250w 4ohms bridged. If you are wiring the coils in series then run a wire from the positive terminal of the first coil (the one wired to the amp) to the negative terminal of the second coil and from the negative terminal of the first coil to the positive terminal of the second. This generally leads to a superior sonic experience coming from your home or car stereo system. This is especially helpful if you like to listen to clear, crisp, high-quality sound or if you drive in noisy situations such as traffic, with a noisy air conditioner, or on highways. Mate i dont have much experience with sterio installs but from what i know a monoblock runs a sub alot better than a 4 channel amp even if it is bridgeable. even if you bridge 2 channels (which provides 150W rms at 2 ohms!) You will be able to find out whether or not your amp is capable of being bridged down from 4 ohms to 2 ohms. Be sure that your use the values for bridged mode, it is usually double the minimum impedance as stereo mode (meaning you need a much high impedance to run a bridged system) a… The formula for finding total impedance for speakers wired in series is Z1 + Z2 + Z3 …. Normally, your 2 channel is running at 4 ohm for each channel. The formula for finding total impedance of speakers wired in parallel is a little trickier. A two channel amp can be bridged to one channel, and a four channel amp into two channels. a 4 ohm sub is going to be 4 ohm, no matter what you do to the amp. Some amps are not rated for going lower than 2 ohms, so keep that in mind when bridging an amp. Connect the ch. Your amp should have a label near the speaker output jack that indicates the output power (measured in Watts) and the minimum impedance (measured in Ohms). all amps that are bridgeable you will notice their bridged impedence is double the individual channel impedence. Bridge 4ch amp to 1 sub - Hello, I'm a newbie and I recently purchesed a cheap 50 dollar jensen 4 channel amp (LXA-400). Now if i get a 4ohm single sub and bridge the the channels (positve from channel 1 & negative from channel 2) will that make the amp run @ 2ohms per channel and therefore be unstable? A two-channel amp will always be bridged into one channel and a four-channel amp will be bridged into two. Before attempting to bridge your four channel amplifier, make sure, it's bridgeable. Connect the positive end of the first sub's first coil to the positive end of the second sub's first coil. 1: Have both subs running on channel 5 in parallel at 2ohm / splits on channel 3+4 leaving channels 1+2 unused. Regardless of where the amp is getting its’ remote turn-on voltage, this will allow you to turn the amp off while still playing the radio. The sub will suck nearly no current from the signal (so your mains will still get almost all the juice), expensive subs have nice crossovers you can use in this configuration. How do I bridge a woofer when I have one single voice coil and one double voice coil? input switch that shouldn’t be needed. the impedence the amplifier sees halfs when you bridge it.
