Posted March 30, 201114 yr ive been into car audio for three years mostly kicker but i decided to upgrade i have a rd1750.1 and a sundown nightshade v1 d1 15 i am new to hi end car audio so can someone tell me what voltage my output should be to have my gain set correctly at 2 ohms which is 840 watts and at point five which is 2225 watts please would appreciate the help dont wanna clip my new set up
March 30, 201114 yr Author Voltage=sqrt(RMS x impedance of speaker(s))Why do you need those exact numbers?right now i have it ran at two ohms at 840 watts but i have the electrical to run the amp at .5 and the rms at .5 is 2225
March 30, 201114 yr Author .5 is a huge draw. What's your electrical?new conceptz 0 gauge throughout big three 300 amp ho alt kinetik 3400 up front and 1800 in back my amp has the same board yours does
March 30, 201114 yr Noice. But really i would advise setting your gains by ear. Turn it up 'till your sub(s) start to show signs of too much stress (weird sounds/bottoming out/smoking/smelling/etc.) or your electrical is dropping too low. Then back off a little and you should be good! Keep an eye on everything for a while to make sure nothing is going wrong.

March 30, 201114 yr I'm not the one to ask about boxes. I leave that to the pros hope someone can chime in on that more.If you need a design check this guy out.Good stuff right there. There are a lot of box builders around. Give someone a shout out and they can set you in the right directions.
March 30, 201114 yr 3.5 seems a little small for a 15, I'd try for a tad more air space. Your doing sub up port back?
