Nikitaaa Posted August 13, 2013 Report Posted August 13, 2013 So I have a AB 750.1 @.5 ohm My voltage drop is about 13.5-13.6 at the back batteries at my peak frequency. Everything else stays around 14v full tilt. my voltage meter is calibrated and accurate. My electrical consists of a dc 180 amp alt, 2 stinger spv 44's, and a kinetic 1800. 2 runs positive and no dedicated neg runs. Am I crazy or should I be dropping more? I remember my crunch 3000d at a quarter ohm would give me more voltage drop than this amp. But then again I only had one battery in the back and one run of positive.. Anyways, help me out guys! 2007 M/T Honda Civic Coupe EX (4) Sundown Audio X-8's (2) Ampere Audio 3800.1's (3) Stinger SPV-44 Batteries (1) Mechman 240 3:1 Ratio 4th order sealed from the trunkTEAM NWSPLBest termlab scores to date in Honda trunk:151.7db legal (official) IASCA trunk 3 classBest termlab scores to date in my walled Subie:152.9db legal (unofficial) IASCA advanced 2 class155db outlaw

TeamHT Posted August 13, 2013 Report Posted August 13, 2013 Have you clamped output? Maybe you're not wired to half like you think or rise is just keeping your setup safe. Tell me...does this smell like chloroform to you?
Kyblack76 Posted August 13, 2013 Report Posted August 13, 2013 Have you clamped output? Maybe you're not wired to half like you think or rise is just keeping your setup safe. Yep.. i agree. You are sure your at .5 nominal? And if so, you have rise like a mother fuck...... SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold

TeamHT Posted August 13, 2013 Report Posted August 13, 2013 On a 7,500 watt amp with a 180 amp alternator and three batteries...yeah, no difference in voltage should be evaluated. Tell me...does this smell like chloroform to you?
Swordlordboy1234 Posted August 13, 2013 Report Posted August 13, 2013 Complain because im not dropping LOW ENOUGH. is it loud?

Nikitaaa Posted August 13, 2013 Author Report Posted August 13, 2013 The amp gets warm to the touch. So I know it's not backed off THAT much. Checked with my pos multimeter and my impedance is exactly .5 at the amp after checking the resistance of the leads. And no, I'm not complaining, I'm concerned. Edit -Yes, it's quite loud. Last time I got it on the meter it did a 49.9 at 38. Score is higher now after a lot of changes though. 2007 M/T Honda Civic Coupe EX (4) Sundown Audio X-8's (2) Ampere Audio 3800.1's (3) Stinger SPV-44 Batteries (1) Mechman 240 3:1 Ratio 4th order sealed from the trunkTEAM NWSPLBest termlab scores to date in Honda trunk:151.7db legal (official) IASCA trunk 3 classBest termlab scores to date in my walled Subie:152.9db legal (unofficial) IASCA advanced 2 class155db outlaw
Nikitaaa Posted August 13, 2013 Author Report Posted August 13, 2013 Also forgot to mention I'm dropping from a resting voltage of 15v. So there is about 1.4v of drop. Little less sometimes depending on the temperature outside. 2007 M/T Honda Civic Coupe EX (4) Sundown Audio X-8's (2) Ampere Audio 3800.1's (3) Stinger SPV-44 Batteries (1) Mechman 240 3:1 Ratio 4th order sealed from the trunkTEAM NWSPLBest termlab scores to date in Honda trunk:151.7db legal (official) IASCA trunk 3 classBest termlab scores to date in my walled Subie:152.9db legal (unofficial) IASCA advanced 2 class155db outlaw
