Hey what's up been awhile since i've been around dont have another system installed yet and never had to do this, so my question is how to tell if an amp work's without bringing it to a store would this work, ground of amp to ground of batt, power of amp to power of batt fused of course and remote to power of batt fused anyway. let me know if this is ok and cannott cause any damage. Or if someone has a better idea thanks in advance for the help
