Hi!
Last night i cranked the volume really high and the sound became very thin and hizzy. I´m driving my 100db horns with one t-amp modifyed the stealth way without pot.
***My question is : If i make one amp per channel in mono would it handle more power vs pushing 2 channels?
Happy for answers!

No?
If theamplifier has only one speaker to deal with instead of two and the input is connected together, running the same signal through both channels. I belived it could give more "power" when having less to deal with? 12+12w?
Thanks

What is needed for more power? Either more voltage or more current. By using only one channel of the amp you are not increasing the capability of the other channel. You will lower dissipation in the chip and crosstalk because only one channel will be in use but that's about it.
Running 1 channel alone "might" give you a few % more. But only because of the power supply. I don't think you could hear it.
Somewhere I have measurements of 1 channel vs. 2. I think the difference was about 1dB. Not enough to worry about. At least, not what you hoped for. Sorry.

Well, i hoped that if i used both channels on the t-amp to play one channel from pre that the load for the amp would be lighter and helping the little amp to perform better on high volum.
I´m ok anyway!
Thanks for your answers.

What you're describing is bridging the two channels. Because each channel is already consists of a pair of internally bridged channels, it is not possible to bridge left and right to create a more powerful mono amp.

If you use two T-Amps to bi-amp your speakers there would be a perception of more power. Each channel of the T-Amp would be operating over a smaller bandwidth. Thus, being somewhat more efficient. Using one T-Amp for the right channel and another T-Amp for the left.
Use one channel of a T-amp for the lows and the other channel for the highs. You would have to have the capability to separate the highs and low at the speaker. For speakers that have jumper or bridge plate it is fairly simple to accomplish.
Panomaniac or some others maybe able to quantify the gains if any that are to be had by bi-amping. Short of that bridging T-Amps is a ...no-no.

Are you sure your horns are 100db? My speakers are 98db, tops. With the volume pot at 12 o'clock, the highest I have ever tried, it's deafening. And I'm a loud junkie.
The sound didn't go "thin and hizzy."
I use a close to stock SI. (It's my backup amp.) I don't know what difference the mods do, but the stock SI is very bass shy.

I did not know that connecting positive left to positive right was bridging the amp. I will however use it as suggested in biamping a pair of Tannoys dual concentric drivers with one ch for the high and one for the low.
I might have been a bit quick to post about the problem since i have a temporary setup with a borrowed pre and crap ic´s so i will try again next week when my audiogear hits the door.
