im running 2 12" dvc subs but i only have one voice coil hooked up and i have them bridged to create a 2 ohm load on the amp... the amp is a mono 1700watt kenwood and it says it is stable at 2ohm (850w bridged) and at 4 ohm (500w) i also have it mounted in the trunk so thers not that much ventalation but i just wanted to know if u guys think its over heating bc i got it on 2 ohms, only one vc hooked up, or the location of the amp

You would be wiser to run the speakers in a parallel/series configuration to obtain a single 4 ohm load to your mono amp. The amp won't have to work as hard and won't heat up as much.

First you said it was a mono amp, and then you used the term "bridged" in telling about the rated specs. One or the other but not both. What model is it?

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

The question is: is the amp shutting off?

More info. The model# of the amp and what size power / ground wire is attached to it. Is the gain set correctly?

set the gain right then u need to hook up both voice coils cause useing only could damage the subs so hook up both in parallel/series configuration like sparkie said so the amp "see's" a 4 ohms load and make sure u have the right gauge power and ground wire also then if it stills gets to hot u can go up to ur local radioshack dealer and buy a 12v cpu fan part # is 273-243 price about $15 and use the remote terminal as ur power and the ground as ur negative so the fan only comes on when the amp is on it only draws .16 amps so it wont affect anything and mount next to the amp that fan can greatly help with cooling ive done that so many times and the amps could fry an egg on them but after the fan they would be like warm hope this helps u

Using only 1 voice coil on dvc will not damage the sub. It may bring the resistance down to the wrong load for the amplifer. I have hooked up many dvc's only using one voice depending on the amplifier stabilty, (1ohm, 2ohm, 4ohm.....)and rms power as to not over power the sub. I would go with sparkies recomendation. (paralell wiring) and definetly read up on setting the gains. There are some good posts on this site about how to set the gains. What size pwr cable/grd cable? What your location, if your down south ventilation might be an issue, in my neck of the woods it is rarely a problem on the back of a seat though....my.02..
