i.e. Power across the 4 ohm subwoofer: V x V / R = (28.28)*(28.28) / 4 = 800 / 4 = 400W in bridged mode. You probably have set 1 going to your power amp. How to Connect Step 1. Im kinda new to this. 8Ω : 2 = 4Ω. It looks like your pre-amp has two pre- outputs. I want to connect 2 50w speakers (8Ω) to 1 channel. The volume control will control both sets. AV receivers feature bass management to direct the low bass … You can connect the sub line-in to the second set. Besides, the mid-range frequency sounds are played from the speaker itself. If you are bridging this 2-channel amp to one subwoofer, you will connect one piece of speaker wire from the positive terminal of channel 1 to the speaker’s positive terminal. Check out the Tuning Videos after you have completed Connecting. We connect the same 2 x 50 watts/channel amplifier in bridged mode across one 4 ohm subwoofer. The voltage available across amp’s bridged channels working together in a push-pull fashion is: Total voltage: 2 x 14.14V = 28.28V. so 2 50w speakers can be connected to 1 50w channel? As for the power output to your subs, that depends upon the ohm stability rating on the amp, the impedance of the subs and how you wire them. Parallel: halves the impedance (ohms) of your speakers, but maintains volume levels. A positive and a negative terminal for channel one, and likewise for channel two. Check out the videos below. i gues its a noob question. Just because your amplifier will do 1,000 watts RMS doesn’t mean it’s the right amp to power two subwoofers that have a power handling of 500 watts each. *WILL* damage the amp if the impedance is too low. When you connect a subwoofer to a two-channel stereo, the AV receivers are in the duty of redirecting the bass of the sound and the low frequency sounds to the sub. Enjoy the Music, REL p.s. Once you hook up the sub, you will want to set the gain and … Often times, using a single subwoofer for both systems is desired. A Neutrik Speakon lead in parallel to the speaker terminals on the amp to the Neutrik Speakon socket on the subwoofer. The managed bass subwoofer output from a home theater receiver or processor and the line outputs from a 2-channel preamplifier or integrated amplifier with line outputs can simultaneously be connected to one subwoofer. if you run two 4omh speakers in parallel on a 4ohm amp you're running the amp out of spec and are likely to damage it. Two phono leads from a spare pair of line outs the the subwoofer L and R inputs 3. So that will work. watt wont bottlekneck or whatever? Subwoofer connection to a two-channel system differs from the methods used in home theaters. 2. For a 2-channel amplifier, you will see four terminals. If you have a 2 ohm stable amp, and two 4 ohm subs then you should wire them in parallel. Take the positive leads from each sub and connect them to the positive speaker out on the amp. i got a 2x50 watt amplifier(4-8Ω). 1. Series and Parallel. First off all, let’s see how the bass management works out in a connection of these two devices. There are two ways to wire multiple speakers to the same channel. Don’t choose an amplifier based on a power rating at an impedance your subwoofers cannot provide. From a single dedicated subwoofer out on the amp - one phono lead to the right channel in of the subwoofer 2.
