Yea Issac gave you the equation, but it helps when you describe what you're actually trying to do. How many subs, what each sub is configured to, what load you're trying to achieve, etc.
sorry about the threads, but didn't get an answer in subs so tried in amp's. What I have is 2 mt 15's 1 quad .7 ohm and the other is dual.7 ohm going to 1 2500d, wanting to keep the ohm load at .5 to 1.5
it would be cheaper for me to recone than to ship back. I'll just have to wait till I get the other one. I have 1 250rhcca left the other whent for $300. I couldn't believe it. The 1 I have is being repaird. I have 2 hifonics centurions 100 x 2 1 ohm, 2 mercury's still in the box never opend 50 x 2 1 ohm. My 8 spl 12's, my 225hcca is on ebay now at 102.50. My hifonics zeus 440 is on ebay aswell. I have a rf punch 120.2, a orion275 gsx, an orion hot set up 300 watt, thats all I'm getting rid of. I have been collecting amp's for awhile, and have decided to get seriose about it. That's why I whent with the re mt 15's and orion 2500d, 1 more when I get the cash.
