    I've got myself a Carvin Pro Bass 300 With a 4x10 cabinet. But I would like to upgrade with a 1x15 or 1x18 to go with this stack. but I don't know about Ohm's and stuff.

    The head says it needs minimal 2 Ohms and is 300 watt
    The 4x10 cab is 8 ohm and is 400 watt

    I've got different ways to connect cabs to my top.
    1. Speaker 1 and 2 output with a bi-amp switch
    2. Crossover hi out and low out.

    What should I use, and how does bi-amping en crossovers work?

    I want to have the whole 300 watt offcourse, but don't know how to do it. I want to use the 8ohm 4x10 cab for high-ends, but would probably sell it if i need a cab with different ohm to get more power.

    On top of that I've got an extra question:D : I'm thinkin' of adding an audio-subwoofer for extra lows to go with the 10's. Is it a good idear to connect this one to the lo out of the crossover function? And is a normal subwoofer as good as a cab of, let's say, 17/18 inch?

    Support me!!!!! Help :bassist:

    The 2 ohm reference is most likely a minimum rating, and your amp should produce more than 300w. when run with a 2 ohm load.
    This means you could run up to three, 8ohm cabs, or one 8ohm and one 4ohm, or two 4ohm cabs.

    Most S/S amps power ratings are quoted at 4ohm.

    I checked the Carvin website and could find no info on your amp. They do have a forum, you might get some info there.

    I would not expect any home/car audio subs to work well with your setup, but yes you would only want to send the lows to a sub.

    Adding a 15" or 18" bass-cab should help getting more volume/watts out of your head. I would experiment with using both bi-amp and normal settings to see what works best for you.

    A single 4ohm cab would also cause your head to have a higher output than a 8ohm model of otherwise equal specs.
