Current setup Alpine CDA 9815 JL 300/4 Focal polyglass components JL staging speaker Rockford Fosgate Battery Factory alternator In process of getting a memphis 500 watt amp Anyways.... My JL500/1 died. Getting a Memphis amp now. I have a blade fuse next to the battery terminal and two glass fuses by the amps. The JL doesn't have internal fuses, but the Memphis does. I am assuming the 500/1 died because I pushed it so hard and it didn't have consistent power. I want to protect my investment, should i get a capacitor or should i just put in a second battery with an isolator. It should only be pushing 800watts. I drive a 350z, I would like to avoid the battery if I could, trying to save space. Thanks in advance.
