[QUOTE="subzero, post: 7405750, member: 600350"] There is alot to do here. first you need to get the actual final ohm load on the amp. should be around 1 ohm. Get your self a Digital multi meter. Measure the DC voltage from the battery with you car on and off. Car off should be your resting voltage, Car on is your alternator charge voltage and willl climb with increased RPM. Amyhow. If you have good solid 12V or more, then the amp should do at least rated. Most of the time amps that claim more than rated are banking on a higher voltage from your batts and alt. read section 14-15 [URL="http://mobile.jlaudio.com/pdfs/Slash_amps/1000_1_MAN.pdf"]http://mobile.jlaudio.com/pdfs/Slash_amps/1000_1_MAN.pdf[/URL] 1.5 ohms: 1000 watts x 1 chan. each subs is getting 333watts.RMS.@ 12volts. The guide show also how to calculate the voltage. 1000watts @ 1ohm is 31.62278 ACVOLTS, ----> also on that page. [URL="http://www.the12volt.com/ohm/ohmslawcalculators.asp"]Ohm's Law Calculators[/URL] So what you need to do is just aims for 31.62 AC volts. You do that by measuring the voltage across the speaker output terminals on the amp with the speakers hooked up and make sure the DMM is switched to AC volts. Then you can adjust with a 50 HZ test tone. Make sure you disconect the Mids and highs so you dont blow them. Also make sure your deck "stereo settings are all flat." that means no loudnes, no bass level up or tweet level up, no bass boost on amp. You want everything flat. Your amp should be > LPF should be 100hz or so, and subsonic should be off. again no bass boost anywhere when setting the gain on the amp. Turn the deck up 90% increased.. Anyhow, if you have questions PM me. [/QUOTE]
