    I am just kinda wondering how this works. Say for instance I add a 1000 W poweramp to my 350 W bass head. Does that mean I can run the original 350 Watts with a cab and an additional 1000 W with another cab?

    thanx

    If you have a 350 watt head and a 1000 watt power amp, you could run a line out frome the head to the power amp. Unless your amp is weird, you can use the head the same way you did before, and then hook more speakers up to the power amp.
    In this instance you are using the head as a pre amp for the power amp.

    Did I make any sense?

    Also, you could run the speaker outs from to the power amp, and have equal power to both cabs.

    Yeah, if you run a line from your head's effects send (or your last effect) to the power amp in and then a line from the power amp's slave out to your head's effects return, you'll be pushing both amps. You could have a biamp rig of sorts--run a pair of 15s or even 18s with the 1000W amp and a 2x10 or 4x10 with the 350W one.

    perfect that is what I am wondering. And to make things more difficult.

    If I used a stereo poweramp with a 350 W head. I could run cab(s) off of the 350 W head. and then run cabs off of each seperate channel of the stereo power amp. Meaning I would have 3 seperate volume controls? right?

    interesting .......

    lets say you have a combo and a 4x10 and the power amp. if you have the poweramp into the effects send and recieve on the combo, can you use the amp in the combo to power the combo speaker and the power amps power to drive the 4x10???

    Yes.



    Yes. Assuming the amp has a line out, or even parralel ins (I beleive) you could do that.

    very simple answer Deman669, thanx

    Freak I was just kiddin' after reading it over I realized exactly what you meant.


    So now could anyone direct me towards some decent poweramps and stereo poweramps. That have about 500-700 Watts per channel. And that aren't very big/heavy.

    Or am I asking too much.

    thanx

    From what I've heard Carvin power amps are really good. Their 1000 watt 2 channel dcm1000's only like $420 or something with shippping.

    yeah that carvin stuff looks excellent. It makes sense why so many people have said great stuff about it.

    thanx

    Indeed. Carvin is just plain great in the AMP department.

    I would pick a DCM over a QSC anytime.
    The DCM is very pure and uncolored.

    If you have a line out or pre-amp out, I wouldn't worry about using the effects loop. Just run a line from the line out to the external amps input. If your amp doesn't have a line out, the effects send should work, but there should be no need to come back from the power amp to the effects return. Both amps should be functioning without the need of such a connection.

    Claremore OK.
    I am running a carvin DCM 1500 and love it. I got for 440 bux off of ebay and it was only 6 months old. It runs 750wt per side at 2 ohms. I just got some new cabs to go with the new rig, and I can run both cabs (4ohms each) on one side of the amp at a full 750wt and still have another channel left. I plan on adding a real sub later.
