Amp cutting out intermittently
I have a Sony XM-280GTX amp that I am using to push 2 old school MTX
Thunder 3000's..(Been serving me well for almost 6 years now!) The problem is this..I just recently put the new amp in..works great..gets SUPER hot though. It's under the passenger seat in my 94 Acura integra. After running for a while.(1/2 hr, 45 min.., something like that), the amp starts to cut out. The song will be playing and then there will be no bass for like 2 seconds then its back..as time goes by, the length and frequency of the bass leaving starts to increase..I checked under the hood..everythings ok. Checked the amp..All the connections are tight, sealed, etc. .I read in my manual that if the sound is interrupted the "thermal protection" may be activating and to "turn the volume down." I am assuming this is what's happening.. So am I just stuck with only being able to listen to music loud for a short while ? There is air flow..Nothing is under the seat but the amp..The amp touches the top of the seat a little but I can't prevent it. .Any ideas? Is it dangerous to run it to the point of the thermal protection kicking in alot? I don't wanna screw up the amp..But I mean I don't think i'm overtaxing the amp it just gets REALLY freakin hot.. What do you guys think? Thanks in advance -Jordin M |

Amp cutting out intermittently
This is a pretty common Sony problem. Some units never come out of thermal
protect. -- --------------------------------------------- :-D I just cut the cheese! "UserJ" wrote in message ...

Try mounting the amp somewhere else?

What do you guys think? You're over taxing it. I'm just guessing that your subs together form a 2 ohm load (assuming they are both 4 ohm SVC), and that you are running your amp bridged. The solution would be to hook the amp up so that each channel is running a sub. You'll lose a little bit of power, but your amp shouldn't overheat on our any longer. -- Lizard teamROCS #007 / Technical Director / Founding Member *res derelicta* http://www.teamrocs.com/ X-Header-PO: This Line Exists to Violate Usenet Protocol, Disregard |
