    Default Amps Over Heating

    So I was out this weekend tied up on the island and my exile amps kept over heating and cutting off. The air temp outside was probably around 100 F so I know the conditions were not great but my buddies boat next to me never had this problem. I could only play for about 20 mins at a time and then it would just shut off. Anyone else have an issue like this and if so how did you fix it?

    What's your battery/wiring setup? Did you discuss with Brian at Exile yet?

    I have a pair of JL Audio MHD 600/4 amps and one of them keeps going into protect as well.
    Built an amp rack with cooling fans and it helps but it did not solve the issue completely on hot days and running the tunes wide out. Chalk it up to a day in the life of a bigger system. You can spend more & more & more & more and upgrade till your hearts content. I just live with it and prop open my observers seat and take it easy on the hot days.

    Wow, I'm really surprised you're having this issue with Class D amps...

    i have no talked with brian yet but my wiring set up with 0 gauge wire from the battery to a distribution block, then 4 gauge wire from there to the amps.

    i did just talk to the exile dealer brian had build my sub box and he said its 113 heat index outside, they are going to shut off and his do the same thing. he recommended a 12v fan that plugs into the cigarette lighter for hot days

    Rd, I'm running the Hybrid setup on my tower and I am shutting my Harpoon down as well. I've got external fans wired permanently in that blow "cooler"(if there is such a thing during Texas summer) air directly onto and around the Harpoon, as it is offset from my rack by 1/4" and the entire area behind the Harpoon on my rack is cut out so it is completely open behind it. Anytime we play in a cove or beach, I move everything in that compartment out away from the amps and leave the hatch open, but the heat just builds. I'm a little shocked yours is shutting down, same with mine do to the added fans and the amp being open all the way around.

    I've talked with Brian a bit, before as well as after, and we agreed that I would be a tester so to speak for the Hybrid setup and the Texas heat. For my situation, it looks like I may be diving off into another 800.4 to help cut the Harpoon some slack. First, I am going to add another fan either behind my rack blowing onto the rear of the harpoon, or add one on the front side on the opposite corner of the existing to blow the hot air back out the front of the open hatch, so it circulates a little better. From what I see so far, the Texas heat you an I deal with is going to be a monster for us. I've even contemplated some vents in the walkway that let more fresh air into the back side of the rack, with a fan pulling air in through one.

    Unlike you though, I played for about 2 hours the other day at about half volume (which is very loud) before I had a heat issue. After the first shut down, it happened 2 more times, about an hour apart. When it's playing, it sounds amazing, lol. It has only happened that one day, where it did it those 3 times so far, but I'd like to do something to eliminate it if possible.

    RD- give me a call at the office. Let's do some trouble shooting. Various things can do this. Harpoon should do very well i'n that environment.

    That is the same solution I have come to with my Kicker ZXM700.5. Kinda embarassing when you are rocking out and like 4 or 5 boats or listening to your system and it goes into protect and everything stops...One time I used the inflater that we use for the tube to blow air on it until it cooled down enough that it would come back on...fun times!

    If you're chillin in the water you could pull the bow seat on that side and open the compartment door just to get some airflow through there. It's been so hot this summer somewhere close to a month straight with above 100 temps.

    I have had this happen numerous times, We tend to play our amps to the maximum causing them to get hot. I ended up buying an amp that I can still get enough power out of, at 4 ohms instead of 2. It can run at 2 ohms (more power) but just gets even hotter. Now that my resistance is at 4 ohms I never have them get hot at all and never shut off!!

    Dont push your amps to the max, or they will overheat in that cubby.
