OrionStang Posted August 27, 2011 Report Share Posted August 27, 2011 A 7,5k only does 2200 at 4ohms. Just get a 2k and run it at 1 ohm and save yourself some money. But I can see your stuck in your ways so, good luck on getting loud. Quote SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
vettedude102 Posted August 27, 2011 Report Share Posted August 27, 2011 I know exactly how you feel on not enough room. At least you have places to put batteries.

monkeyleg Posted August 27, 2011 Author Report Share Posted August 27, 2011 You would rather run at 1 ohm than 2 or 4? I was going to get a 7.5k on the two 12's, but if I'm running three 10"s then I'm going to need a 9k. The subs are still getting the power, it's just the car electrical I'm worried about, LOWER RESISTANCE = MORE AMPS. My car can't make those amps. To everyone else, thank you Quote Google it Link to comment Share on other sites More sharing options...
vettedude102 Posted August 27, 2011 Report Share Posted August 27, 2011 Its better to run at one ohm because you ain't like wasting wattage. Like why get that big of an amp if you aren't going to use at full potential Quote 2 polk audio 4x6'skenwood head-unit 220 amp Mechman alt1979 Corvette 2003 corvette z06 alpine radio and the bose system that came stock Link to comment Share on other sites More sharing options...

Like why get that big of an amp if you aren't going to use at full potential When the time comes where he can beef up the electrical, if he decides to do so, he now has an amp that will butt fuck any 10, 12 etc he hooks it up to lol Quote Team NWSPLUPCOMING BUILD (when I afford it) 2013 Ford Focus Hatch 2x DC lv3 15s 2x b2 quotas XS batts DC power alt That amp would fuck the shit out of those subs. It would roofie them, knock them out with chloroform, then make sweet, gentle, anal love to them all night. Link to comment Share on other sites More sharing options...

Like why get that big of an amp if you aren't going to use at full potential You are wasting "wattage" when you run at lower resistance. Your amp isn't as efficient, that means you need WAY more power from the source to produce your "wattage" Example with random numbers. Amp needs 10 amps from alternator to make 100 watts at 4 ohm Amp needs 100 amps from alternator to make 100 watts at 1 ohm, the rest is heat, in the wire, in the alternator. It's like a teenager running at 10 miles an hour vs. a senior citizen running at 10 miles an hour. The teenager can do it for days. he senior citizen is long dead by now. Think of your poor alternator Quote Google it Link to comment Share on other sites More sharing options...

Think of your poor alternator 100 amps to make 100 watts at 1ohm? I think your math is off. based on that math, i am drawing 1500 amps in my set up. (sorry, i see the random numbers comment now) You are right, efficiency is lower at lower resistances, but it isn't nearly as much as you think it is. If you can't support 3k watts @ 1ohm, you very likely can't support 3k watts @ 4ohms.

I just think it will help out running at 4 ohm because I am powering other things in the car, 30+ speakers and 17 T.Vs Quote Google it Link to comment Share on other sites More sharing options...
