i have a caprice with 140amp alternator with big3 (4 gauge) and 4 gauge wires. my old system was a jl 500/1 and a jl 300/4 with no problems. to help sell the car i put in rockford 500.1 and rockford 400.4 still with no problems. got a dc lvl 4 15 and hooked that up to the rockford 500 temporarily and it sounds great. nice and loud.
so i buy a sundown 1500.1 on here. i hook it up in my car (to test) and theres literally next to no sound coming out. it powers on, no protection mode, but the sub isn't even moving. i wire the sub down to 1 ohm and turn the gain all the way up. still barely moving and not doing anything.
would having 4 gauge cause that much of a difference to where this normally powerhouse amp to barely move my sub? the rockford 500 moves this much harder than the sundown which isn't right.
