daisy chaining subs and stereo amp

[apocalypseon]

Will this config work?

Line out from laptop -> L+R line in on subwoofer plate amp -> L+R line out -> plate amp 2 -> plate amp 3 -> stereo amplifier -> speakers.

Will this result in a low pass signal, from plate amp 3 to go through to the stereo amp? Or will it be a full bandwidth line level signal?

It depends on the particular plate amp if it filters the signal. If it does not the only other issue is that your line out may not be happy driving so many amplifiers, but if it's a dual headphone/line socket it should have the current to do so.

This is particular model. http://www.parts-express.com/yung-s...ofer-plate-amplifier-module-no-boost--301-500
It doesn't say whether the line out is filtered or not.

You're talking about the laptop line-out I suppose? It's definitely a headphone out. Probably a dual headphone/line out. Has a little headphone symbol. So, from what I understand, headphone outs have lower output impedance. In my case, will it be happy driving these many amplifiers? I don't have an engineering background.

I'll look both up. I have another idea. Laptop headphone/line out -> Stereo amp with line out. hi-level ->speakers. line out-> plate amps 1,2&3. Is this pretty much the same as above except that this signal wont be low pass filtered?

I am asking since, I'm considering a small tripath amp with no line out. And I'd also like to avoid a preamp or external dac. Due to budget constraints. Atleast for now.

The page says it has line level loop through so you should be OK. Yes, headphones are much lower impedance than an amplifier so being a headphone output it should drive all those amplifiers no problem.

Yay! Richieboy! I sez yay! Sounds good to me! In either case, if need be, I can add a hifimediy dac later. Now a couple of days more of wait. Decide the final budget. Finalize all the components. I can feel all my "research" paying off. Thanks mate.
