Normally, your 2 channel is running at 4 ohm for each channel. It it NOT necessary to bridge a multi-channel amplifier to make it produce maximum power. = Ztotal. It should be apparent by the markings on the amp. Thus in effect doubling the power each channel, say you amp was 200 watts. Still have questions? This generally leads to a superior sonic experience coming from your home or car stereo system. Assuming the sub has a 4 ohm voice coil...and only concentrating on 2 channels, you need to take the positive from one to the positive on the sub and the negative from the other to the negative on the sub. Is my vehicle compatible with this aftermarket stereo? Also, there is the question of whether or not your amp can handle additional speakers. The best you can do is 150 watts to the speaker out of a bridged 4 to 2 channel setup. Experts recommend using two identical subwoofers for optimal sonic quality. So when connecting up your left channel you would connect one wire to the front + and the other to the rear -. If it is capable of driving (powering) low impedance loads, then it can be done. The formula for finding total impedance of speakers wired in parallel is a little trickier. $$$ The RMX 5050 may be a better option. Mono block amps are sub amps. If you choose to wire the subs in series, connect the negative end of the second coil in the first sub to the positive end of the first coil in the second sub (these circuits can get complicated fast). The following diagrams are the most popular wiring configurations. Join Yahoo Answers and get 100 points today. Thanks to all authors for creating a page that has been read 228,424 times. a 4 ohm sub is going to be 4 ohm, no matter what you do to the amp. it says something with built in cross overs? To feed the 300 watts you would only need 12 gauge from the battery and for the ground. With Kenwood, there would be a switch to bridge it to 2 channel. Get your answers by asking now. You can still connect a head unit car stereo with only 2 channels (left and right) to a 4 channel amp easily. You can do it, but keep the level low because you will be pushing the full power of the amp to just one sub. Well, your subs are dual 4 ohm voice coil subs. all amps that are bridgeable you will notice their bridged impedence is double the individual channel impedence. If the dual VC was 2x 4 ohm, that would give 2 ohm; if the SV is 4 ohm, you add the 2 to get 6 ohm. You would need the owner manual to know for sure. Bridging amps is a common process in car stereo systems, as it allows for increasing the amp's power output. You don't have to use both channels (you probably don't have to bridge both either if you want to use the spare channel to amplify your two back speakers at 75 watts each). Wire each sub's coils in series ... wire one pos and one neg together on each sub. Or would it be bad for the amp? Each pair of pairs is a bridgeable set, when bridged, you only use the outer screws of the 4 as one channel, and the two middle screws go unused. The results will display the correct subwoofer wiring diagram and impedance load to help find a compatible amplifier. If you look at the amp it will probably be 2 pairs of screws side by side, then some adjustments, then 2 more sets of screws. It's not the best way, but if you can get the subwoofer signal to be mono, it should be fine. Use the positive from channel 1 and the negative from channel 2 to one of your subs.
