How to keep my subwoofer from blowing?

Keep Blowing Fuses On My Amplifier and Subwoofer?

  • I have a single 4 ohm Boston Acoustics g5 10" subwoofer hooked up to an Alpine PDX1.6. My subwoofer is 450 RMS My Amplifier throws out 600 RMS at 2 ohm and 4 ohm. Whether its 2 or 4 ohm, it puts out the same wattage, so dont question this. My amplifier has been tuned by a professional. My wiring is yes the right gauge infact. Everything is properly secured ground, etc. So when I Turn my Subwoofer up why do I keep blowing fuses? Sometimes its on my amplifer sometimes its on my subwoofer. Im getting pisssed off cuz these fuses cost like five bucks for two.

  • Answer:

    www.12volt.com check teh fuses on the amp versus power to see how much u need. fuses may be too low. now the voicecoil fuses popping on the G5? I'd double check teh polarity AND wiring. I had a similar issue with my speaker wiring and reinstalled the sub box wiring and the fuses stopped blowing. Some wires were trickling out. I love thos Boston fuse holders. They are in fact the correct amt for the voice coil I hear so the standard stock should work. My guess is wiring issue. possibly a remote wire being grounded or one of your speaker wires touching ground or crossing over or maybe out of phase.

well i had this same problem. i had 20A fuses that kept blowing so i went and just bought 30A fuses and they haven't burnt yet! if you do this and they still keep blowing buy a bigger fuse for the power wire. i have a 100A fuse in my power wire

try checking the fuse in the fuse holder, all fuses must be equal in total. lets say your amp has 2 25A fuses thats a total of 50A your fuse in the fuse holder under the hood must be 50A if its lower it will continue to blow.

you have a fuse on your sub?!?!?!? am i the only one that doesnt under stand this?!?!?! if your amps fuse keeps blowing when you turn it up make sure you have the RIGHT size fuse in DONT start putting bigger fuses in your amp or youll break the amp or start a fire if the inline fuse TO your amp keeps blowing make sure its 10 to 20amps bigger than the fuses on the amp any smaller and itll blow if you actually have a fuse on your sub (wich ive never heard of) either use a peice of 12 guage wire as a fuse or use a fuse 10 to 20 amps bigger than the fuses on the amp good luck

First place to check would be for loose wires, I would tighten everything down because a loose wire can easily cause this.
