Amp or Subs poured smoke!

[Southeast Rage]

I drive a 2008 Hyundai Tiburon GT Limited. I have gone through 3 different Amps in less than a year. In my car I have a Planet Audio 3000 watt mono channel class D Amp, three 10" Power Acoustic Subwoofers Dual voice coil (RMS for 1 speaker is 700 watts with peak power of 1600 watts), a 0ga power wire and ground wire, the paint on my frame was grinded down to the metal for the ground, and a Power Acoustic Single Din DVD/MP3/SD/USB headunit.

Well driving down the road the other day, I had the system going the backseat down and the windows down. I heard this crack like something just popped and started smelling smoke. By the time I knew it my whole car was smoked out. I stopped on the side of the road and popped the hatch and my 3 10"s were just pumping up and down every slowly. Also the Amp light was still on like nothing was wrong but it kept smoking. I have the subwoofers set up to run at only 2 Ohms. I don't understand what is happening. This will make my 3rd amp that is blown.

Can anyone give me some insight on why I keep blowing these things???

Well, you obviously need to rip everything out and see where the majic smoke icame from........next time, buy something better and quit maxing out your stereo

I say your problem is running PA equipment

Not the best out there //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

(by a long shot)

ya know, you'd be a lot more helpful if you didn't jump to conclusions like that.

If you have a 1/0 ground from the amp to frame but a 10 gauge ground from the frame to batt... then you have a 10 gauge ground

what is your electrical?

lol if something in my car poured smoke, id rip it out and see what happened..........from the amp.....could be voltage drops, overheating, or just a simple FET, either way he needs new equipment. to the op, sorry to sound harsh it just that its happened to you twice before and it happens a third......it dont sound like an equipment problem

This needs to be fixed bar none

OP, exactly how do you have these three subs wired to 2ohms ?

 

[Bg's 10+ year member]

theyd all have to be all dual 4 ohm subs coils in series subs parallel

yup, cause three dual 4ohm subs can wire to 2 ohms... //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

You still don't get two ohms.

4+4=8

1/((1/8)+(1/8)+(1/8))=2.66666667...ish

I'm assuming your amp is the AC3000.1D which is stable to 1ohm (it claims) so you could wire it a little lower.

Make sure your amp has plenty of airspace to cool off.

Make sure your speaker wire to the subs is big enough.

Those are all the suggestions I have //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif let us know what it was that blew the smoke and we can help a little more.

No.......

u take 2 8 ohm loads and wire them parallell you get 4. you take a third 8 ohm load and wire it parallell to the others.......you get 2 ohms

You never really wanna do this.

Umm pretty sure this is correct

Umm pretty sure

You're pretty wrong //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

It is 2.67 ohms. 4 dual 4 subs wire to 2 ohms. 3 subs always wire weird if they are 2/4 ohms.

 

[Bg's 10+ year member]

then whats the rule of thumb when dealing with ohm loads, do 2 4 ohm loads not wire up to 2 ohms parallel anymore?

If its the subs that were smoking its because you didnt tune your amp correctly and the subs saw a very nice clipped signal that put them on the edge of catching fire. If it was the amp I bet money on voltage drop popped some internals and caused some magic smoke.
