seeking some advice, I have a four channel amp (alpine pdx9) and a MiNiDSP C-DSP 8x12,i want to run a three way active however i don't have enough channel on the amplifiers, my question is can i run the tweeters directly from the DSP without going through the AMP, thanks

Ok, but wait, my HD900/5 gains get set to something like 20v I think. 20v is 100w so wouldn’t pre outs be 5w per volt? I very well might be completely looking dumb but couldn’t 10w run a tweeter quite loudly?

Wait till someone in the know chimes in lol. Aren’t coaxial outputs like hundreds of ohms? Might be like bridging an amp down to.0025 ohm load.

Mini DSP8x12v2 output voltage is 4.5V RMS MAX - If you put a 4 ohm load on it the most youll ever see is 5 watts... voltage squared divided by resistance equals power (watts)

I bet in most cases you would not be getting more than a watt though... its just op amps on the outputs.. not enough juice to push even a tweeter.. well it might be audible but i dont think it would be close to sufficient.

There are many many tiny little amps you can get for tweeters.. i use a Eton micro for rear fill that will fit in the palm of my hand... i think its like 60-80watts x 2... alot of great options out there. Amps are hard to screw up nowadays.. but not gunna lie I am running Gold modded Genesis just for the Fu$# of it... but I would definitely put all my $$$ into speakers and DSP way before amps.. just get anything thats not a Crunch or Pyle and youll be OK.. LOL

Just because a device can output 4.5V doesn't mean it can source enough current to actually drive 5 watts of power. I work with lots of micro controllers that output 5V but you can't pull more than a few miliamps on any of it's lines. Generally speaking the mini DSP is expecting a high impedance load possibly as high as 47k. 4 ohms is just going to drag it to 0 all the time.
