4 channel amps were not designed to power subs. 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). For example, a 2-channel amplifier rated for 75 watts RMS per channel at 4 ohms may be able to put out as much as 200 watts at 4 ohms into one channel when bridged, which can be very convenient for powering a subwoofer. You could connect a speaker to each channel. This article was co-authored by our trained team of editors and researchers who validated it for accuracy and comprehensiveness. Wire each sub's coils in series ... wire one pos and one neg together on each sub. For DVC sub, the wiring is basicly like 2 svc sub for each driver/speaker. This article has been viewed 228,424 times. Basically, the main process is the same for every single channel. Normally, an amplifier may consist up to 4 channels. (you'll know by looking at the maxx power and WRMS of the sub and the amp). how to bridge 2 svc 4ohm subs - Hey everyone, I just wanted to make sure im going to be doing this correctly.THe amplifier is a Power Acoustik 1600 watt 2 channel amplifier. 6 + 8 = 14 Ohms 3) Divide the top by the bottom to find your total impedance. Bridging amps is a common process in car stereo systems, as it allows for increasing the amp's power output. If you have four channels (1,2,3,4), you can bridge channels 1 and 2 together, and then bridge channel 3 and 4 together. With Kenwood, there would be a switch to bridge it to 2 channel. Now wire all those pos and negs together ... you'll be at a 2 ohm load, but that's as good as you're going to get. If you bridge an amp, you are using 2 channels to make 1. (the numbers are just for reference) Buy a mono subwoofer amp that would give the sub 200w, or bridge a 2 channel amp for slighlty more power than the mono amp, say 220w. 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. You'd set the A channel to HPF and the filter frequency to 60-100hz depending on the quality of your speakers, and you'd set the B channel to LPF and the frequency to about 80hz. As far as your speakers to the amp, it's possible but I would not reccomend it, I'd say get a smaller amp, ex. Let's say I have a single sub I want to drive, and I have the following options. To bridge the amp, connect the subwoofer or bridged speaker positive (+) terminal to the positive amplifier bridged terminal label, and the speaker negative (-) terminal to the negative bridged amplifier terminal also. http://www.crutchfield.com/S-TAmvZqGPEq6/learn/lea... Will I get cancer from a cd player with radio? The majority of amps on the home theater market are only stable at 4 ohms when bridged. Finally connect the negative end of the second coil to the negative bridged terminal on the amp. Most amps won't do 2 ohms bridged. This is mainly done for subwoofers, as it changes it from stereo to mono and doubles the power. You should fuse the battery hot at the battery (incase of accidental damage resulting in short circuit) make sure it is rated at the total amps of the unit. For tips on the best way to set up your home network, see, All tip submissions are carefully reviewed before being published. Connect the positive end of the first sub's first coil to the positive end of the second sub's first coil. Most amps will display how to wire this up with the connectors. simple answer is yes, i would have the sub run off of a bridged 2 channel and the speakers wired to their own channel. With Kenwood, there would be a switch to bridge it to 2 channel. You need 2 amps to power 4 cabs, and you need 4 cabs to go decent low. But if not you can leave the spare channel unused. By using our site, you agree to our. all amps that are bridgeable you will notice their bridged impedence is double the individual channel impedence. If you have one and about to start bridging it, here is the procedure for you. At 150 watts you only need 14 gauge stranded wire to feed the speakers. This is an example of a 2 channel amplifier running mid range speakers and then a sub configuration. If an amplifier is 2 ohm stereo stable (and therefore 4 ohm mono stable), it will produce the same power into a 2 ohm stereo load as it will into a 4 ohm mono load. Also, there is the question of whether or not your amp can handle additional speakers. a 4 ohm sub is going to be 4 ohm, no matter what you do to the amp. You can sign in to vote the answer. The best you can do is 150 watts to the speaker out of a bridged 4 to 2 channel setup. Select your Woofer Quantity and Woofer Impedance to see available wiring configurations. Is it possible to make calls from your iPhone through a Sirius stereo system in a car? How loud is a 24,000 watt system with 3 18's? or both? Is my vehicle compatible with this aftermarket stereo? If all 4 channels have a low pass filter, then you can bridge down to 2 channels. 300 watt maxx power depending on the maxx wattage of the speakers. This generally leads to a superior sonic experience coming from your home or car stereo system. Pimpster, Ty is right. Thanks to all authors for creating a page that has been read 228,424 times. 2ohm stable..Here are the sepcs SPECIFICATION 2-Channel 310W x 2 RMS @ 4 ohm 370W x 2 RMS @ 2 ohm
