Default pre-amp to power amp

ok, would running audio out on a pre-amp(that is amped 10w rms) to a power amp of wattage 1)cause distortion?(would distorion be caused by using the amps in series), 2) increase dbls significanly(or modified to increase dbls), 3) increase wattage to speakers?


thanks for any info

" dbls " = probably decibels

Hi Baldlobo,
could you rephrase your Qs. I (& maybe some others) am having trouble understanding what you want.

I think he wants to plug the output of a smaller power amp into the input of a larger one, to get more power than each one individually.

But I could be wrong.

If that is the question, then the answer is no... worst case he may let some smoke out...

Please do! No disrespect to you, but there is a lot of nonsense on the internet, and it looks like you have found some prime examples. However, you've come to the right place to get decent advice now.

I don't think anybody wrote something like that. You might have misunderstood something. You can for example use headphone amp as a preamp, but it is't connectes with increasing the output power.

It can be done... to be safe using attentuating Rs (exactly what plate amps do if you are using the speaker level inputs), but you get only the power output of the 2nd amp. In this case the 1st amp still sees a real load as well, with just a trickle bleed off to feed the sub amp.
