I doubt its volt now.. i put my yellow top in the trunk now, now when up high the highs amp chips out. I got them bridged to a 1000watt pyramid 4 channel amp, im only using channels 1 and 2 tho and gain only half way up. Only door speakers go to it. And i have fused 60a wire to back battery, then wire from there to 60 a fuse splitter, 60 a fuse for both amps, then power to amps. When base up loud the fuse in the splitter pops, should i just run a straight wire from trunk battery??
