2 amps bridged

[nda0602v6]

Its been quite a while ago but I had asked this question once before but I never really found an answer to it yet. What I would like to do is power a set of component speakers using two amps. One amp would power the Left component speaker and the other amp would power the Right component speaker...both amps would be wired in bridged mode. (small amps....they put out 100watts RMS when bridged). The only thing I'm not sure about is how to wire up the RCA's to the amps. Bellow is a diagram on what I think would work? Even though the amps are bridged mono, i'll still be able to get stereo separation because each amp will power the left and right side. I know i've seen people do this before but I'm just not 100% sure how the RCA's go.

Re: 2 amps bridged

Just looking for the extra power? Not normally how bi-amping is done.... lol .... but I don't see any reason why it wouldn't work. What's the need for the RCA Y-adapter's? Are both amps the same model? And I assume both speakers are the same....

Yeah both amps are the same. (PPI A100's). I'm thinking you would have to use Y-adapters because since you only have one rca for each amp, the amp needs two (left and right rca inputs in order to bridge...atleast I think) You mentioned this is not normally how bi-amping is done... let me know of another way if you know of any. I just want to make sure its right.

Re: 2 amps bridged

if the amps are normal they dont need both, just 1 input, i would plug it into the left input, simply because that is mono

.... there's only inputs for one pair of RCAs on a 2-channel amp. Think you're confusing it with a 4-channel. You have the amps already correct? Take a look. :stp:

And bi-amping is usually done by powering the woofers separately from the tweeters. Eliminating the included passive crossover all together. Commonly done when different brand components are used and being run by devoted DSP or active crossovers of some kind....

lol No i'm not confusing it with a 4-channel. I know there is only "one pair" of RCA's on a 2-channel amp. But if you only have "One" Rca..ex: either a Left or a Right RCA...(not a pair) and yet you have a "pair" of RCA's on a 2-channel amp...that would leave One RCA open on each amp. Thats why I used the y-adapters lol I hope that made sense.

i know where you are coming from, but you are absolutely unessicary, you are only using them for a single channel, so hook the left rca up to the amp that is doing the left speaker, and the right rca up to the right amp, its that simple, you do NOT need those Ys it will work with just a single channel because that is what you are using it for, just trust us.

Ohhh ok ok I see now.:banana: I doubted you were making a mistake like that, lol, but I just couldn't figure out what you were getting at.:p

You WILL need the y-cables. Because you intend on using both channels on both amps. Both channels need a signal of some kind, right? Yep.:naughty:

And bah, there is no "left pair of RCAs". It's front and rear. The front pair have left and right. And so do the rear pair. Think that's where the confusion is coming in....Nda's diagram is misleading.:D

Re: 2 amps bridged

from what i see he is just using an amp for a channel, not front and rear, just 1 speaker, which means he just needs the left signal or the right signal, depending on what speaker the amp is going to. you dont need 2 channels of audio if you are just using it for 1, they just mix together when, or it just uses the left input depending on the amp, you can have 1 channel of a 4 channel amp hooked up and is it not going to work because you dont have 3 other channels plugged in, no, you just need the single lead, no use in splitting it, that is if he is only doing 2 speakers which from my understanding is what he is doing, it doesnt matter if the 1 rca open on the amp like he said, it makes absolutely no difference in the end

Yeah..........what!?!?!:poke: There's one period in that entire paragraph......and about 50,000 fragment sentences....:spank:
