ZachG Posted August 15, 2012 Report Posted August 15, 2012 Ok so I read here how to figure out my output voltage for my amp and how to set the gain. http://knowledge.sonicelectronix.com/car-audio-and-video/car-amplifiers/how-to-adjust-amplifier-gains-using-a-digital-multi-meter.html The number I came up with is 57.67v My amps birthsheet says it does 1,663rms at 2 ohms. Before I go and set my gain on my amp to this I just want to make sure this is correct 1998 Pontiac grand prix gtp supercharged2 12" Obsidain Audio V.1 on a 2011 zx1500.1 at 2 ohms. 20ft of Knuconceptz CCA 0 Guage. 2nd Battery is a Shurken BT-120. Box is 3.5cu tuned at 31.8hz sealed off from the trunk. 14sqft of Dynamat on the Rear deck top & bottom. Soon to be more for doors/roof. Gets low & loud Did a 140.5 Sealed at Battle of the boom in June 2013 dropping to 12.7v (need a alt mines going bad)

HunterJohnson Posted August 15, 2012 Report Posted August 15, 2012 dont set ur gain with a dmm. Scion tC SQ BuildiPad mini, lots of fabrication, daily drivenFord Explorer C Pillar Wall Build Just a cheap car to destroy with bass
CJ18 Posted August 15, 2012 Report Posted August 15, 2012 Not accurate. Do not rely on this. Go to the tools section here and check out the dd1. That is what you need to properly set your gains.
BASS_ZEALOT! Posted August 15, 2012 Report Posted August 15, 2012 dmm? this is PREPOSTEROUS... GET A DD-1 DONT BE CHEAP STEP YOUR GAIN UP !!! DD-1 SMD makes the best products! I bought them all! Click the banner below!

ZachG Posted August 16, 2012 Author Report Posted August 16, 2012 A dd-1 is like 170$ That's a lot to use it a couple times, how bad could it be if I used a dmm 1998 Pontiac grand prix gtp supercharged2 12" Obsidain Audio V.1 on a 2011 zx1500.1 at 2 ohms. 20ft of Knuconceptz CCA 0 Guage. 2nd Battery is a Shurken BT-120.

n8ball2013 Posted August 16, 2012 Report Posted August 16, 2012 While you will see that alot of members will advocate using a dd1 or oscope this is better than nothing. Its a crapshoot at best though. I have a scope and a dd-1 and i really prefer the dd-1 its just so simple.
