I have a 6-zone amplifier powering 12 speakers (whole house). Now I have added an additional 2 speakers on top of the 2 I already have outdoors on my deck. This brings the total to 14 speakers total. I do not want to buy another amplifier so I was thinking of using the zone for the deck speakers for 4 speakers. This way the zone controls ALL outdoor speakers. I do not mind about having less power so long as it is not a drastic difference being that for outdoors a high level would disturb my neighbors. Will this harm my amplifier, speakers? What other safe way is there without buying another amplifier?
As you add speakers in parallel (+ to +, - to -) the total resistance (also called impedance or Z) decreases. Most amplifiers are rated to drive a 4 or 8 ohm load. The closer the impedance gets to 0, the harder the amplifier has to work.Usually you don't want to go below 4 ohms with consumer amplifiers. Most speakers are 8 ohms. Two 8 ohm speakers in parallel 4 ohms. The best way to wire four speakers to a zone and keep the impedance at 8 ohms is to use parallel/series wiring. Wire both of the pairs in series, then parallel them together at the amplifier. I'll try to explain this more clearly: From the amplifier, the red (+) goes to the + of the first speaker, the black (-) of the first speaker goes to the + of the second speaker, and the - of the second speaker goes back to the amplifier. You now have two speakers wired in series. Repeat for the other pair of speakers and you now have two pairs wired in series and paralleled at the amplifier. Your total Z will be about 8 ohms, which is ideal for most amplifiers. You can use this parallel/series wiring scheme to add as many speakers as you want, as long as you keep the total Z around 8 ohms. The formula for figuring total Z of parallel wired speakers is: Total Z 1 ------------------- 1 1 1 --- + --- + --- + R1 R2 R3 That doesn't type out well here it's 1 over (1 over R1 + 1 over R2 + 1 over R3, etc) Also known as the reciprocal of the sum of the reciprocols! R the resistance of each speaker. The formula for total Z in series wired speakers is: R1 + R2 + R3.
It will halve the resistance(OHm) load on the amp (depending on how you wire the additional speakers.) Check and make sure that the amp is capable of the load placed on it, and it should be fine
do no longer, I repeat no longer, connect greater effective than one speaker output to a connector as suggested above. you will RUN the possibility of FRYING despite is offering the sign. i does no longer plug your audio gadget in to the subwoofer. there's no reason to. you will might desire to easily connect them to the lower back of the receiver itself the place they are labled middle/FR/FL, or something to that effect. check out the lower back of the Sub, commonly you will plug it in to the connector that pronounces (Mono). i think of it truly is the purple one, yet do no longer quote me on that. additionally, in case you have your manuals, you will possibly desire to seek for suggestion from them. in case you do no longer, they are obtainable on line from that manufacuterer's internet site.
Hello, yes you can run 2 more speakers on those channels what you have to get is a Y splitter for each and plug them in and then plug your speakers to them! you will lose some power though!
