Same issue with the same amp or a different one? Problem with mine is, the temp outside could be 75 or so and same issue.

 

If you put some spacers between the board the amp is mounted to and the amp itself, it will allow additional airflow behind it and should cure any overheating problems, if indeed that is the issue.

 

One thing you can try is to lower the crossover point.

250Hz is too high. Set it down to 120Hz and see if that helps.....Also check your ground point for good clean contact with the frame.

 

The amp is installed directly onto a carpeted board with the bottom of the amp literally on top of the carpeted material. I always thought this was iffy, as it seems to trap a lot of heat. Is this a normal mounting method or are spacers normally used? I'm going to run out and quickly check the grounding.

 

from what i've seen, mounting the amp directly to mdf or carpeted mdf is normal, with some setups even installing trim around the amp to make it sit flush--further impeding it's heat-dissapating abilities. that being said, i'm just regurgitating advice someone else gave me on my setup. seems to be working so far. I have an Alpine mrv-f345 amp.

 

Fwiw, my amp is mounted the same way (trunk wall, on the carpet), and I have no overheating issues, but did have a clipping issues with a improperly wired dvc sub.

 

Do you have the Bass EQ switched on? If so, try turning it off and turning down the gain on the sub a little. Also, turn down the crossover point on the sub to 150-180 or so.

 

Were you having the same issues? As in, the music just goes dead for a few secs and then comes back on and goes dead again, until either you lower the volume or turn down the sub output to fix it? I'll be sure to check the status light next time when it happens, does anyone know what color indicates overheating for Alpine amps if any? I don't think it is clipping, but I could be wrong, because with clipping, you still hear the music, whereas in this case, it goes silent for a few secs. When I get some free time, I'll look to add spacers or cut holes in the board if the general consensus from the s2000 community here is that it is heating issues and nothing something else. I just hope, I won't have to go to the extreme of installing some fan blowing at the amp, hahah, that would really blow (pun intended) .

 

The Bass EQ was on before, I had turned it off, because it was just overloading the woofer and I think it was causing some clipping too. I'll definately look to also lower the crossover point as a few have suggested. Would turning off the crossovers and giving both front speakers and the sub full range help, hurt or not make any difference?

 

The fronts don't have a x-over so set them above 65. Don't run the sub full range, no point, it isn't designed to do that. If it's still going into protection after lowering the gains, you'll want either a separate amp for the sub or a bigger/better 4 channel amp.
