Amp problem

  

Zincpony -> Amp problem (7/17/2005 11:56:49 PM)

as im driving my system is thumping, the dance floor is jumping it goes off. I just hooked up the Amp and the subs today. The AMP is a Xplod 1200W 2channel. and the subs i forget. but as im driving the thump goes out completely. I just installed the sound system 1 hour before this post. IDK what the problem is. I looked in the trunk and the AMP was on fire. It was really hot. and the little LED was red when it should have been Green. If i turn the head unit off then back on again it comes back up but just enough to thump for a bit then goes out again. what could it be.

Your amp is overheating. You either need to have it open so that it gets more air to it or turn down the gain on the amp so that it doesn't get as hot. The reason why it shuts off is so that it doesn't burn up.

04redmach1 -> RE: Subs or Amp problem (7/18/2005 2:57:02 AM)

find out what subs and ohm they are. Amp isnt greatest in world. Could be wrong ohm load or as said above turn it down.

Black Snake -> RE: Subs or Amp problem (7/18/2005 3:23:27 AM)

Yeah its prolly over heating Xplods are natorious for overheating specially if theres not open space around and if it hot outside. If its not that check you connections ground, positive, and speaker wires. You also may want to tweak with the output adjuster on the side if it too high it will overheat.

Zincpony -> RE: Subs or Amp problem (7/18/2005 5:00:54 AM)

the amp is in the trunk in front of the subs. as soon as i open the trunk lid there is the AMP and behind it is the sub box. if thats one of the reasons its over heating where could i run the amp from then? yea yesterday i didnt play enough with the adjustors in the back of the amp i need to configure them nicely.

myfirststang -> RE: Subs or Amp problem (7/18/2005 5:11:53 AM)

With it being in the open like that it will be fine. What is the model of the amp that you have and what are the models of your subs. I think you might have the same amp as me, XM-SD22X. You probably just need to turn down the gain or bass boost on your amp. Subs won't hit as hard, but they will be hitting harder than they are with the turned off [;)].

mine is an Xplod XM2200GTX
this right here.

im having trouble with this. i got to find some way to get a cooling system for the amp if this doesnt get resolved.

i have the 1600w sony amp i had it where the spair tire is and a week later it over heated and
went caboooom ,so i returned it and now i have it sittin in front of my box and its been fine ever since then.

Zincpony -> RE: Subs or Amp problem (7/18/2005 5:12:12 PM)

i moved it i pu the rear seats down and put the amp there just to test it out still overheaed. Kinda took just a little bit more time then previous. Plus i also changed where the ground wire was. Where do you have yours grounded to?? im still pissed about this. wtf

gettna05! -> RE: Subs or Amp problem (7/18/2005 5:29:33 PM)

Can't too small a size of the wires cause too much resistance and overheading in the amp?
A quiet little computer fan from Radio shack might do the trick.

Zincpony -> RE: Subs or Amp problem (7/18/2005 5:56:48 PM)

my parents are on vacation and they took my digital camera with them. but id be posting pictures left and right on my set up. i might have to try that out and hook up one of those. but damn more money. im gonna go to circuit city and see if they can possibly tkae a quick look at my wiring set up or maybe Tri State Audio.

Could it be that the lights on my subs, also hooked up to my amp, be overheating my AMP

myfirststang -> RE: Subs or Amp problem (7/19/2005 5:07:00 AM)

Yea I fogot about the wires. What gauge wire are you using. Did you turn the gain down at all? what is the model of your subs? When I ask the gauge im talking about from the battery to the amp and from amp to the speakers.

sowaxeman -> RE: Subs or Amp problem (7/19/2005 9:59:03 AM)

Sounds to me like an impedance problem - either from too much load from the subs or too small speaker wire. If you are pumping out serious wattage, you shouldn't be using anything smaller than a 10 or 12 awg wire. If you are using 16 (or worse - 18!!!!) then you are generating excessive heat.

What impedance is the amp rated at with the config you are running? Look in your manual - and example would read:

Stereo - 4 ohm
Bridged/Mone - 2 ohm

If you are running an amp at 4 ohm, but your sub/s are rated and wired in a 2 ohm config then your amp will overheat.

Zincpony -> RE: Subs or Amp problem (7/19/2005 10:47:10 AM)

im using 16 gauge wire from the remote to the amp (its yellow wire like me car) amp to subsi think its also 16. and the wire from the battery is pretty big im also not sure what it could be. ill check it out.

88lx5.0 -> RE: Amp problem (7/19/2005 11:46:20 AM)

ya another problem i had was the settings on the amp were not tuned , so make sure your gain and all that other stuff is good.

myfirststang -> RE: Amp problem (7/19/2005 12:43:04 PM)

Whoa! You need at least 4 or 8 guage wire for as much power as your pushing. Make sure you have the a good fuse on the wire though so you don't fry your amp. You can ask a custom car audio or call crutchfield and ask them how big of a fuse you need. But yea dude, you definitely need a better wire.

Zincpony -> RE: Amp problem (7/20/2005 1:11:37 AM)

i dont understand how the gage wire and the resistance on this works.

sick95gt -> RE: Amp problem (7/20/2005 1:54:21 AM)

its probably an impedance problem. I've been installing those amps forever now and they don't really like being below a 4 ohm load. As far as the guage wire, it's transfering your current from your battery. Imagine running a marathon breathing through a straw. Your amp is starving and wants a better voltage transfer.

myfirststang -> RE: Amp problem (7/20/2005 5:30:00 AM)

Without giving you a class on basic electronics, it would be hard to explain. If you go to http://science.howstuffworks.com/electricity.htm you can have a good understanding about electricity.

But the basic principle here is the smaller wire you use than the higher the amperage that you are going to have, which will generate heat. But if you use to large of a wire than your voltage will suffer and you won't have enough juice to power your stuff. Like I said, you can call crutchfield and ask them what is the best wire to use and even order one of their kits. But I would go iwth either 4 or 8 Gg wire.

Zincpony -> RE: Amp problem (7/20/2005 9:17:29 AM)

so which wires should i change all of them,
the one from the battery to the Amp
remote to amp
amp to subs.
