Amp blowing fuses!!!

[Eckstream1]

Anyone know why my aftermarket Alpine amp is blowing fuses?
I got my car all wired up last night and went to put the amp in... Hook up all the connections... Pop in the inline fuse on my power wire and BLAM it blows both 15 amp fuses in the amp...

The strange part is that my ignition was off and the remote wire was unplugged... Also my inline fuse on the power wire was still intact.

I went over all my wiring... Good power, good ground(tried 3 different ground points) and good remote...

I also tested it on a power inverter to see if was my wiring... Did the same thing hooked up to the inverter...

I was up till 1am trying to figure this out so if you have any suggestions it would be greatly appreciated!

it could be a variety of things. You could have the sub-amp combo mismatched. If the amp is too weak for the subs, the amp will trick itself to "try" and generate more power hence blowing fuses in self preservation. Your wiring could be wrong, not heavy enough gauge wire. Companies are constlantly mis-advertising amp kits, the use a sh!tload of insulation but then you cut it you barely have any wire there. OR you might be using too weak of a fuse. Post some more info bruh: what kind of sub/amp/wiring/fuses.

looks like you covered all your bases on testing at this point sounds like it has a fried input or output circuit not much you can do unless your good at testing circuits even if you are most manufacturers use proprietary components so its nearly impossible to find replacement parts... Best bet get another amp you can have your fixed but in my experience fixed amps usually don't perform as good........

I had bought a brand new amp a few years ago and it wound up being bad; went through this same scenario. I would hook up my power wire as the last thing and the fuse kept blowing; it was a 100-amp fuse, too! After going through like 4 of them, I thought it was maybe due to the fact that my battery was still hooked up, but I always installed subs/amps with the battery still hooked up before, so that wasn't the case. Yup, my amp was bad; just took it back and swapped it out.

He said the inverter fuses popped too..... I know its a stupid thing to say... make sure u dont have your wires crossed....... how do u have the power and ground wires ran?

[Eckstream1]

I made sure I used proper wire... 6ga power, 8ga ground, 14ga remote... Power wire is connected to positive batt terminal.... Ground is grounded to a chassis ground(good solid ground) and my remote wire is tapped into fuse #18(cig lighter)....

Its a real mild set up- 2x Alpine V10 subs ran in parallel and a Alpine 4ch amp(not sure on the model # but its a 500 watt amp) thats bridged...

It only pops the two 15 amp fuses that are located on the side of the amp...
It does not pop my inline fuse on the power wire...

The only thing I can think of is I just disconnected the ground wire on the batt... Hooked everything up... Reattached ground cable to batt(this is when it would pop the fuses)

Should I disconnect the power and leave the ground attached? Then wire everything up... and reattach the power wire?

for a simple test wire size doesnt matter you can jump a wire from the remote to the power doesnt really matter just as long as they both get 12v I would also have no load (sub disconnected) doesnt matter if you touch power then ground or ground then power the amp should simply turn on if you have power and ground connected to a source and then touch the remote wire you should here a click wich is the internal relay switching the amp on....

some amps have signal sensing make sure this is turned off if your using a remote power connect (not sure if your amp has that feature) this feature uses the signal from your RCA to turn on the amp some amps dont like both in use at the same time

Thanks Bigal... It sounds like its a short somewhere internally. I have been through my wiring several times and this could be the only possible problem... Ill be swinging by Tweeter to look at a new amp...

[Bigal470]

no problem.. wow you guys have tweeter all ours closed down

I agree with BigAl. Audio amps have high-power transistors. If they short out, you will blow fuses all day. It may make a nice paper weight if you decided not to get it fixed. Even with no load (speakers) connected, the amp will continue to pop fuses.
