Default Overheating Amp

I have an Audiobahn 1600 Watt Amp and two 12" Audiobahn Sub woofers. The amp is wired with 4gauge power (with a 60 amp fuse) and ground wire, wired through a capacitor. Now the problem with all this is that when i run it, which normally is about half power on the cd deck and 2/3-3/4 power on the amp itself, it will only work for about half an hour to 40 minutes and then cut out b/c it over heats. I've check all my connections and they're solid, no rusting or loose connections so I know thats not why it overheats. This is a picture of my setup at the moment

I was wondering if anybody can think of any reasons why it would over heat after such a short period of use, or even over heat at all. Thanks for your help!

wrong forum, but I'll chime in, anyways....

it all depends on what the resistance on the subs are. something tells me they're 4ohm subs. and they look like they're dual voice-coil, as well. dual voice-coil is one of those neat things to have that really doesn't help much, IMO.

you're probably running too low a resistance for the amp, which is over-working it and causing it to over-heat. try unplugging one of the leads to the amp (it won't sound as strong, but will run without overheating).

your subs will sound better in a sealed box pointed to the trunk vs a board with them pointed into the seats. there's more space to resonate.

if you're intent on using both voice coils, get a better amp thats stable at lower resistance.

if you don't understand resistance and ohms, go to a stereo shop and get schooled.

Sorry I guess I missed the audio forum some how. I'm working on the sealing them up, hopefully within the next few weeks i will have the rest of the box done.

So pretty much dual voice coils are a neat little extra but don't help much, and in my case causing it to over heat? And if I unhook one of the voice coil wiring it will not over heat?

those are steps in the right direction.

I never saw dual voice-coils as much help. all they're good at is helping lower the impedence, which would be good if you ran one sub. and like I said, the lower the impedence, the more power that makes it to the subs, the louder/stronger they sound, which is why they won't sound as good once you unplug the wire. but they won't over-heat your amp anymore....

the subs I currently run are single voice-coil (alpine type-e's, nothing fancy). they get the job done.

Well that didn't solve my problem and my amp still over heats. Any other suggestions that I can try?

Find out what the impedence of each voice coil is and if its SVC or DVC, enter info. Find out what your amp is stable to and wire accordingly.

How do I figure out what my amp is stable to?

Get the model number and research it. Why does it feel like I have to hold some peoples hand the entire time...
