[QUOTE="trumpet, post: 8274915, member: 628688"] Use OFC power and ground wire, minimum 4 AWG. 1/0 AWG is better. Upgrade the battery-to-chassis ground and alternator-to-chassis ground, running both wires in addition to the factory grounds and connect them at the same spot on the chassis. I haven't been doing this, but you may want to run another ground wire to the chassis up front from your current amplifier ground location. Unless it's a dual trace oscilloscope the best you can do is set up the amplifier for no clipping at maximum output. I wouldn't bother trying to dial it to XXX number of watts, because if you can't calculate the phase angle it's just VA you'll be calculating, which is not Watts. Don't know, I've always known it to be PPI so I keep using it. [/QUOTE]
