Xdq_21X Posted May 12, 2016 Report Posted May 12, 2016 I'm trying to find out the wattage my amp is putting out. So I'm trying to figure this out cause I can barely turn my gain up any or else it'll start clipping (I have a DC 2.OK and it has a clipping light). so I want to know how much I'm putting out before I drop an extra battery in so I can compare it. I hooked up my multimeter to the positive and negative of the speaker outputs on my amp and I got 33.5volts. I then cut the positive speaker wire and hooked them up to the multimeter (cause I don't have a clamp meter) and I got 5.85amps...so 33.5 x 5.85 = 195....so my amp is pushing 195watts? that's doesn't seem right, any suggestions?
Efreakingt Posted May 12, 2016 Report Posted May 12, 2016 When you tested the volts did it have a speaker load on it and did you use a test tone?

Xdq_21X Posted May 12, 2016 Author Report Posted May 12, 2016 what do you mean by speaker load? and yes I was using a 40hz tone
Xdq_21X Posted May 12, 2016 Author Report Posted May 12, 2016 its just a stock head unit from a 2015 Chrysler 200
Efreakingt Posted May 12, 2016 Report Posted May 12, 2016 Were the speakers hooked up during the test? If yes then you would have to know the ohm load of the speaker at that frequency. From everything I've read, using just a dmm is pretty hard for benching an amp. A clamp is the easiest way to go.

ShadeTreeMechanic Posted May 12, 2016 Report Posted May 12, 2016 If the head unit is clipping, then your amp wont have a clean signal. like the old saying goes "garbage in, garbage out". 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon)
