If one of these connections ends up reversed (i.e., positive to negative instead of positive to positive), then the they are both old amps and are expendable. (Image credit: Denon) The principle here is that you have two systems that meet in the middle, but don’t overly impact one another. Since the cables are identical, it doesn't matter which wire pair goes to which crossover side. If you connect the speakers in series, you're adding the speaker impedances together. Yes, you can, if you have an amplifier. You would set the crossover on the top amplifier to high pass and the crossover on the bottom amplifier to low pass . This one’s just for speakers, and rather than wattage, sensitivity is the measure of how loud a speaker will be in decibels when 1 meter away and being driven by 1 watt of power. The pre-out option is the way to go. Erm, yes? Over the years people have found creative ways for enhancing sound quality beyond just buying more expensive speakers. You cannot magnify the power of one amp by chaining it to another. A good tip when connecting any audio components: Connect outputs to inputs, to outputs and inputs, all along the audio device chain. You can connect your speakers using the regular left and right speaker wire connections and ignore the second set of terminals. … This is a very common wiring use of a 4 channel amp for situations in which you’d like more power available and don’t need 4 separate amplifier channels. i have some fairly powerful speakers … For this case, you want to put your speakers in series, so the total impedance of the speakers will be 8+8=16 … Step 1 Turn around each speaker you'll connect to the amp or receiver to … Thread Status: Not open for further replies.

Having recommended a range of speakers and amplifiers for every turntable set-up, we asked The Ear editor Jason Kennedy to share a few essential tips on how to match them. Assembling a separates-based sound system is essentially a case of getting a turntable (or CD player/computer & DAC etc), an amplifier, and a pair of speakers… For a practical discussion on how to simply wire just 2 pair of speakers to a stereo amplifier (4 speakers to a stereo amp), see my article on How to connect 2 speakers to 1 amplifier. Determine what type of cable you need. Class A is 25% efficient, which means that for every 100 watts of electricity used, only 25 of those watts go to power your speakers. Connect the wires by plugging in each pair of cables from the amplifier/receiver to the terminals on the speakers. can i connect 2 amplifiers together (parallel) with the same inputs to increase the output power? For example, if your TV only has a stereo headphone output (called a 1/8 stereo jack) and your amplifier only has RCA audio inputs, you will need to use a "1/8 stereo to RCA" cable. hi everyone, as you can see im new to the forum and Im a moron as you might have gathered from the title of this thread. Avoid connecting the subwoofer with speaker wire. This diagram shows how you'd connect 2 amplifiers if the amplifiers had internal crossovers. For the most part, “Strapping” – aka ‘Bridging’ – TWO amps together is done to get Double the @1ohm Power Rating of One Amp. In a simple bi-amped system run in mono, a single stereo power amp can be used by assigning one channel for low frequencies, and the other for high frequencies. A 4 channel car amplifier bridged to 2 channels.
