I have a JL Audio 500/5 amp and the recommended fuse is 50 amps, but the guy at Tweeter told me that it would draw 80 and i needed a 100 amp fuse. Anyone know which I should used from experience?

Thanks in advance,
Jason

 

I would go with what JL recommends since they designed the amp to begin with. Let's see ... 500W / 13.8V = 36A ... and that is nominal. When your voltage drops and you get more current, I would start worrying. At 12V, where you are no longer charging your battery, you are drawing 42A. No worries man! Get the 50A fuse. The tweeter guy probably does not realize that the amp will only rate at 500W total, regardless of the impedance attached to it. He most likely thinks that if you attach a 2Ohm load it will jump the output to 1000W which would require an 80A fuse.

Make sure the idiot wires the speakers up the right way! He will probably try and set it to 2Ohms, and I believe that the amp will actually sound worse at that level of impedance.

 

I would go with what ever is in the manual. You know the JL experts put the correct info in their manual.
