Okay so last night, i had the subs cranked listening to Gorillaz.
I noticed the backlight on the deck was dimming with each bass hit. Then Poof, no more bass.
I checked the fuses.
The inline fuse in the engine bay, between the battery and the amp was blown, but not only that it was bulged and melted, so i pulled it out in 3 peices with pliers.
Today I replace the fuse with the same amperage level(30) and now my subs are louder than they were before.
What would cause the amp to not only blow but melt and bulge.
I am running approx 75watts RMS, should my deck light be dimming like that.
A loose or corroded connection will cause it to draw more current then it needs.
To pull 20+ amps your connections need to be very clean and TIGHT.
Check the fuseholder and make sure the connections there are good and its not a piece of shit.
Poor connection, or a potental short. Shouldn’t be drawing anywhere near that amount of current unless you have some insanely inefficent amp at that wattage. Or something else running on that circuit.
yea the fuse amps rating sounds about right for the power your pushing…usual rule of thumb that ive heard is the amount of amps the fuses on your amplifier are using (say its 3 - 30 amp fuses) you want to pair it with the same or a tad bit higher amp rating for the in-line fuse…using 3-30 amp fuses, use a 100 amp fuse under the hood…if the battery and alt. are fine then idk…what kind of amp/sub setup are you running??
How are your speakers wired? It’s pretty easy to over draw an amp. Most amps become much less efficient as they’re over amped but will continue to operate until they overheat. Some amps, especially smaller amps can run at 2-4 times capacity before they get hot enough to shut down. Are your speakers in wired in parallel through a single channel?
The other thing that could cause those conditions is a poor battery connection, or a poor connection on the chassis end of the ground wire from the battery. I would crank it up, and put an analog volt meter on across the lead battery connections and look for dips below 14 Volts when the bass hits. Good luck
hahah. Get a REAL ground wire. Ground wire should be at least the same size as the power wire and should be a good connection. Bad grounds can somtimes fry amps. Oh yeah, turn your gain down
Electricity works both ways. Your ground MUST ( as in no fucking exceptions) be the same size as your power wire. As much electricity or more goes through the ground then your cough “power” wire.
