Car Stez Set Fire Twice

[Woody1]

Okay guys, i am a person that like my Music, this car has been tested by Boston and both Alpine, they still cant work out why my car started a fire both TIMES! yeah not once twice.

Okay so i am only going to bother listing the bass side of it because thats where the problem is.

First time around i ran 2 Alpine R's with 2 PG mono blocks 15.0:01 they are 1500wrms each. this lasted like 2 years so i was happy but then only 2 weeks ago the coils heated up that much that it set fire to my boot, i put the fire out without damaging my amps or my boot thank god because i was at a stop when it happened.

Alpine said that a massive amount of Dc was sent to the coils of each R and they acted as a heater and melted. And the only way this could have happend if it touched metal or i earthed it out on somthing.

Alpine would not warranty anything because they were not there at the time to be able to know if i was the one that caused this to happen.

This setup is coverd by perspex and all wires are covered in a heat proof silicone so there was no false

earth.

I pulled apart my system as it needed to be redone after the fire, but first i tested both of these amp's in diffrent cars of my own and ran them for 2 weeks with earthquake sub's nothing melted or burnout.

Cheer's Alpine so i told them to shove it went out and got myself some G2 12inch bostons, installed it into my R33 and what ya know next day they stopped working, i pulled them apart, the fuses in the back of the bostons melted to the back of the magnet, the metal was untouchable for about 3 hours, they were not turned up above 1/4 because i was letting them ware in be4 i gave them a belting i normally do this for 20 hours running time and slowly turn them up.

So i rang boston, they told me its either my apm's or my car's alternator, i tested these amps in another car for 2 weeks nothing, as for my alternator i had it tested and ran a smooth 13 volt's so there was no issue there, they said it may be intermittent, so i set up a cam corder to my volt meter so i didnt have to sit there =D let my car run for a total of 8 hours then just fast forwared the video there was no change to warrent the alternator being the problem.

ANY IDEAS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!????????????????????????

- Sound cables serrated and shorting...

- Poor connections? Or underrated cable?

- was the alternator tested under load? even auto-sparkies f**k up the most simple of tests

Just a few to check of the top of my head.

Specifically did Alpine say high amperage killed it? or high voltage? theres a difference.

NFI - how loud do you run it though?

I'm a pro right?

Sounds like your amps... The power supplies have a habit of either earthing out when they get older (tiny bits of metal here or there, I've seen Alpine miss a shard 4 times that f**ked up an expensive amp), causing them to flow power all wrong and heating up like a light bulb...

But in the same way, the amps can f**k up and send off a largely f**ked power signal (dealt with that myself, there is a technical term for what happens, but I had a big one last night, gimme a break ). Either way, I have come to find that the sompanies that make the hardware, are not all that interested in helping you out... they would rather you just buy something new... That being the case, run all the normal tests, move amps to other cars, try different wiring, though it sounds like you have tried half of that stuff...

Another thing I would suggest is to take it to a proffesional amp fixer who has nothing to do with the company, some people outsource their amp fixing to some really shitty companies (never EVER break an earthquake amp, just trust me on this one...) and they can VERY OFTEN miss something, and not fix it...

Good luck though, sounds like a rather unique problem

Edit: For the record, I may have had the same problem once... My amp got extremely hot (never on fire, cause I was testing it at the time) while just being on... never cranked, never put under and decent sort of load for a 3000WRMS amp... The mosfet power converter was farked... i think... again... big night...

did you use the same cabling this time as last time? is the speaker cable two cables stuck together, or seperate strands? if stuck together, check for continuity between pos+neg and move the cable around a bit while your doing this as it may expose a short/break between them

get some new cable anyway, and buy the cheapest sub you can for testing purposes (should only be like $50 or something)

[R TUNE]

what size cable you running. the cable might have to much current running through it and causeing the cable to melt and therefore shorting out or the subs are takeing a lot of current for some reason. only other thing i can think of mate.
