burning coil smell

[corey0928]

And burning Coil smells different than burning glue off. Does it smell like something burning or does it smell sweet

So i bought some AA hovocs and i didnt mess with any of my gaines or anything on my deck when i put them in and yes i tuned it wtih my dd-1 and when i was playing the song bass cannon by dj slow n throw i smelled my coils burning i immediately turned it down so my question is dj slow n throw shit is clipped to hell or is there somthing else wrong because i can play decaf or bigpimpin and not have a problem.

If you set your amp gain with the DD-1 and didn't touch any of the levels on your deck, you did it wrong

That may be true, but I believe he said he set the settings and then did not touch after installing the new subs.

I dont member and i sure dont want to try it out agine lol

This is correct i set the settings like it said in the dd1 manual and after i installed the new subs i didnt move anything

Djsnt usually states frequencies in each song. Even with a dd-1 u can clip ur amp by dropping voltage or by playing a song louder than the tone used when setting gain with dd-1. Also, with a ported box the sub moves the least at and around tuning, so lots of power while the sub is barely moving can heat a coil up quick. Playing below tuning can really start to cause problems not only thermally but mechanically as well.

I have checked my voltage regularly well most of the time i play it loud i hook up my MM and it usualy dont go below 13.5

Warm coils have a smell even if they are not in danger of melting down. Just how it is... the adhesives release some gases when heated. If you had to get your face in the port to smell it's probably fine.

You'll know you fucked up your sub when you tune it a little under the amp's capacity and your amp goes into protect mode at some point (like at half volume). That's because the voice coil/s melts and its impedance is lowered, which the amp would not be stable at. At least, depending on the amp. Mine is only 2ohm stable and if it goes into protect after smelling that, then I know the coil is melted. If you had a 1-ohm stable amp and played a 2-ohm compatible sub, and the coil/s melt, then, you'll probably notice it gets much much louder and eventually you'll fuck up the suspension rendering it worthless. Keep in mind, running subs with melted coils means you can still hear output from it, but if the amp isn't stable @ that impedance, then you risk damaging the amp as it gets MUCH hotter (which shortens its lifespan) and usually goes into protect from that alone. The same goes for blowing your speakers and running a 4-channel.

How to prevent this:

1) play songs at least 128kbps, 192kbps or above is preferential -- try to get 320kbps songs if you can

2) don't use bass boost -- ever, anywhere

3) watch your voltage constantly - always. if your battery and alt aren't enough for the amp's demands, you'll notice the voltage dropping way down while parked at a stoplight for a while, and that's not good for your amp or your electrical and in turn not good for your sub/speakers either. if you need to hear it loud at a stoplight, put the car in neutral and rev the engine between 1 to 2 RPMs, just enough to feed your amp. if you run into this problem a lot, then either upgrade your electrical or turn down the system and drive for a while to charge up the battery a bit more. you'll notice it's way more of a problem in the summer time, and not a problem in the wintertime (if it gets quite cold where you live). oh, ps: always warm up your voice coils before blasting it when it's cold out.

4) make sure your ground is *bolted securely* onto the chassis after sanding it well

5) make sure the ground wire is short enough, and at proper gauge

6) solder and crimp your connections, use insulation too

7) use proper gauge wire for the voltage requirements

8 ) make sure your box is custom built close to the sub's specifications

9) set up your LPF and HPF properly

10) tune your system with a sine wave and make sure it's a little under the amps capacity at most by using a voltmeter and referring to the power chart on these forums

11) ensure your headunit's ground is secure and solid. and any crimped connections are secure.

12) if you have screw-down terminals, make sure they're nice and tight

13) make sure you've done the Big 3....

once you have all this set up... just make sure you give your subs some breathing room of voltage when tuning in case you're playing a clipped song, because that clipping causes increased power consumption and that's usually the cause of blown coils. that, and bad ground connections from either/or the amp and headunit. bad ground taxes your electrical and eventually the battery will shit on you.

i wish you could hear how a sub sounds in a car with complete sound deadening... you can definitely tell when it's clipping. i have my car coated with dynamat xtreme, thus i listen in for clipping so that makes it easier, and watch the voltage when it happens. without a deadened car and properly built custom box, it's sometimes hard to tell.
