I have a 70 amp alternator stock so I bought this battery to run a second amplifier. I installed Polk db6501 components and Pioneer amp. Can't remember name but it has two 30 amp fuses on the side. I had slight head light dimming issues occasionally with my original set up. Digital Designs 512 on a 600 watt Powerbass amp. This took all issues away even with the second amp. The only thing I am slightly worried about is that I wired it to a two year old Gold top battery. I think it will be fine, I've played it every day for three months or so. Great value, great price and it shipped quick. Make sure to double fuse the power wire from the front battery to rear. If you don't know what that means please youtube it and save your equipment.
