I just recently bought 2 12'' orion xtr subs, new in a ported box. Then decided to get a Orion amp, I found a old school Orion 4004 on craigslist for dirt cheap , hooked it up and works great, I wired both subs bridged on the rear channels and had the 4 guage power/ground wire ran professionally at a retuable car audio shop. Everything was good and i mean great , the xtr's are slamming hard but that 4004 amp gets stupid hot , I've read some other reviews and learned that the amp has a protection agianst heat and shuts down at 190 degress. So after about 15-20 mins the amp just shuts down, Then when cooling down comes back on for about 2-3 mins then repeats itself. I tried turning down the gain to less then half way and even tried messing with my head unit to adjust the bass and input , it still gets very hot and kinda defeats the purpose of having that amp. when the gain is at a somewhat safe level , it is like the subs are not even on (very little bass). I belive the subs are the 2-ohm version , but do not know for sure. anybody know what to do?does anyone think a fan would help ???
