[QUOTE="vipervin, post: 3440283, member: 569972"] after reading about how to setup your amp gain through multiple resources, i do not understand why the OP suggests to keep the load disconnected. is this specific only to JL amps? i followed all the steps of the tutorial with my JBL BP1200.1 amp, and output was severely lacking. target voltage is 49V. i hooked up my load and the DMM measured approx. 33V.. a huge difference. i eventually figured out that my amp was actually seeing a resistance of 3ohm, not the nominal 2 ohm. so now my target voltage became 60V. set the gains to this voltage WITH the load connected and it sounds much better. i double checked with my oscope from work and it was producing a clean wave so why is it recommended to keep the wires disconnected? i was reaching no where near the amp's max capabilities using the tutorial.
