Default RE: Subs or Amp problem

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

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.

Default RE: Subs or Amp problem

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.

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.

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.

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.

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

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.

Default RE: Amp problem

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.

Default RE: Amp problem

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