Did I crank it too loud? Or can I blame the eBay wiring kit..

Poor connection caused heat which caused it to fail. If it worked fine for months no problem. Put a new fuse in and make sure all connections are tight and your good to go
wrong. bad connections increase resistance and lower current flow AND voltage the opposite happened.. he exceed the amount of amperage the device could pass and it failed. im not trying to be a **** B. i just dont want people catching there vehicle of fire for recommend the wrong fusing or wiring or techniques..

I think ive posted NEW charts on fuse ratings. and the proper way to test if you wire is capable of properly carrying the current.

ill post it again for evenone to see..

these charts are current tested usually via 5% voltage loss across the conductor under load.

this one is kinda unofficial but the voltage drop calculator is the thing i would look at for conductor sizing

car audio wire is very high strand count and easily handles the 90 degree wire ratings. but remember unless your distro block or battery post is pure copper it doesn't qualify for the 90 degreee rating.

most car audio distro blocks and connectors are aluminum and there ampacity decreases the total circuits ampacity.

Well my system has been running beautifully since October 22. So it's been almost three months of great sound. Then all of the sudden nothing.. The day before I had it up a little louder than usual, and I thought it might be the remote power wire coming loose but I checked all wires in the back of the head unit and amp and all was well, but still no power. So I thought oh well it's just a blown fuse, that's easy.. Until I opened my hood and realized the cable was completely disconnected ?

This is my first set of subs so I'm wondering if this is normal? It looks like the thing blew up ?View attachment 26554244View attachment 26554243
sorry for being a ****. to me this stuff is just common sense.. look at the charts ive ut up and follow the fuse rating and wire ratings. also read up on how to find power(electrical) and understanding basic electrical

. Basic Car Audio Electronics this is a pretty good writeup that anyone who installs should know..

 
yes. a bad connection increase resistance there by decrease current flow.. heat comes from over amperage not a lack of conductivity. this is electrical 101..
If you think having a loose fuse block or loose wire terminal won't cause heat and wire/fuse to melt or get hot you are mistaken

it does happen but fact is a poor connection means higher resistance and lower potential current flow. your are correct there are cases where the connection is good enough to have a low enough resistance to pass ample current then the connection becomes compromised causing arcing. but its few and far inbetween. even time i've see that happen is because the fuse didn't fail and it was the next weak link in the chain.

if this was the case its more than likely the material used in the fuse holder where poor conductors thermally and it couldn't handle the current flow and melted..

quite frankly the stuff in the car audio field *****. most of it is nickel plated dirt cheap steal or aluminum. which aren't the greatest conductors.

Hmm happens all the time around here... Hang out at local audio shop and kids come in all the time my system stopped working. Amps not turning on... Look at the wiring and the fuse is bubbled up, check to see if the connection is tight and every time the lug terminal is loose or the set screw is loose and wire is barely makin a connection... I see it all the time.

lol.. i done electrical for probably 10 years industrial. and no lie i never see loose connections. if anything fuckers over-tighten ****..

**** kids don't know they could burn there car down..

then you cant speak on this subject, its very common for cheap wire to corrode and loosen over time if someone doesnt know how to properly secure a wire. even i go back and double check every now and then to make sure everything is tight, your average person doesnt do this. you're arguing over nothing, what he said is the truth in what likely happened here. let this thread die already

its a legitimate subject. you know what was the leading cause of electrical fires?

it was from using connectors and conductors that weren't meant to be used together. alot of the older stuff used copper wiring with aluminum connectors, often in receptacles and alot of the cheap **** today in car audio aren't rated to be used with copper. the connections came loose over time not from it being a bad connection or vibration. its from using non compatible conductors and/or connectors. the heat expansion isn't linear between the two conductors and one expands more than other causing the faulty connection.. chances are that cheap *** fuse holder was aluminium and not rated to be used with copper and after it getting hot and cold many times it eventually because a poor connection.. even though the connection was good at one time..

let me ask you this..

i have a generator with 4 parallel feeds per phase.. 2 of the wires are hot and the others are cool. which are the bad wires..

which electrical environment are we speaking about. i was answering the real question here, not speculatig on different circumstances? you're asking an irrelevant question.

i highly doubt that the reaction between copper and aluminum would be the primary reason why the connection loosens over time, you do realize the majority of people half ass shoving the wire into the the terminal to begin with? same problem with crimping or spades.
