Can someone help me do some OHMs equations or something?

Discussion in 'Amps and Cabs [BG]' started by Stanley Design, Jun 1, 2004.

  1. I have a 100 watt at 8ohms head hooked up to an 8ohms 410 cabinet.

    I bought a 150 watt at 4ohms combo peavey tnt kickback 115.

    If I hook them together, what will I have? Will I have 125 watts of power to both? Or something simular?
  2. What I think you will have is 75 watts going to the 15 and 75 watts going to the 4x10's since the 15 is probably 8 ohm.

    When you say "hook them together", do you mean use both cabs with just one amp? You'll get more overall power (I assume that's the idea) using both amps, and jumpering (or using a y-cable) to get to both inputs from your bass. This way, you'll get 100 watts into the 4x10 (at 8 ohms), and whatever the TNT puts out into its own speaker (75-ish at 8ohms, as Greybeard suggested, or 150w at 4 ohms, if that is the case).

    If you don't want to carry the 100 watt head, than Greybeard has your numbers.

  4. Where would I pick up a Y cable? How much?
  5. If I hook them together, what will I have?

    Probably a blown head. 8ohms + 4ohms = 2.67ohms and unless your head is rated down to 2ohms you'll cook it.
