Boss 2500d gets hot and trips off and on every 5 mins...

I recently bought a boss 2500d. It performs well during the first half an hour then it trips off, and after five minutes it would come back on or I could I take off the power and put it back on, then it would play for a min and trip off back. During this time the protection light comes on then switches off accordingly. The speaker is new and not faulty and within the stipulated ohms specs the amp is designed for. All connections and wires are new and insulated and well connected including power and ground. Sufficient power is supplied to feed the amp. The amp gets extremely hot when playing at 2, 4 or even 8 ohms at only quarter the gain level and half the head unit, then it trips off. Does it nead a fan or something? What's up with that? It seems as though when the amp is cool it plays continuously. Could it be failing output transistors or a lack of proper contact thereof?

The amp is monoblock so there is no bridging of a single channel to itself.

If you are bridging the amp then you must DOUBLE the "ohms load" that is specified. I.E. If you need 4ohms per channel, then when bridged you would need 8ohms per bridged channel. If your load is indeed correct then you have a fried output probably. Try to run it without any speakers on it. If it still gets hot then you for sure have a fried amp. All the symptoms you decribe sound just like you have too much of an "ohms load" though.

I have two brand new mofo 122x in a custom box made right to thier specs its powered by the nxd4500 and it plays loud for a few minutes then it only plays at half or at least thats what it sounds like so...

make sure your amp can hold either .5 ohms , 2 ohms or 8 ohms...... by my guess your amp is either 2 ohm stable or 4 ohm stable and you have them wired down to .5 ohm.....this will cause it to overheat and kill your amp. check out it will give you wiring guides for hooking up subs.

If the fuse is not on the outside of the amp, usually near the live input. it will be inside the amps casing. you may have to look around carefully as maybe under parts or hidden. if not on ouside of amp, 100% its inside the amp

For da orion 2500d, what would be the difference between 10'', 12'', & 15'' orion hcaa subs besides a matter of price and inches? I have two of the orion 2500d amps and am ready for the subs. I would...

I honestly would go with 2 12 inch dual 2 ohm subs and wire them one per amp. That will give you a 1 ohm load to each amp and will give the HCCA's 2500 rms per sub... It will be stupid loud... 10s hit tighter than 12's usually and 12's tighter than 15's but u will get more air movement out of a 15 than the 12's and 10s... but... 2 10's require say a 4 cubic foot box to perform well... 2 12's require a 5 cubic foot box to perform well and 2 15's require about 7 to 10 cubic foot to perform to their fullest... no matter what if you put a sub in a box that's too small it will not perform or sound like what you want it to... go 2 12's and like a 5.50 cubic foot box or a 6 cubic foot box and you will love it...

Hi, i would like to know if Boss is a good brand amp for my truck

it is ok. These amps are cheaper and are meant for use with lower quality speakers. So they do work but I would expect alot from it.

Boss 2500GT mono block car amp white smoke after 5 mins

I'm not familiar with this particular model but this appears to be the filter inductor in a class D amp. If I had to guess, the white smoke is from the filter capacitors connected to this inductor.

You should check with Boss to see if it's available. If it's not, you can re-wind it. You'll need to measure the diameter of the wire to determine its gauge.

If the filter caps vented, you'll have to replace those also.

*amp to sub wiring help...

The 2500D has 2 "+" and 2 "-" power connections to help split the current between two smaller wires vs. one giant, hard to route wire. According the manual, for optimal performance, both "+" and "-" power connections should be utilized. They also recommend using 4AWG wire for these connections.

The 2 "+" and "-" speakers connections are only there to simplify the wiring of multiple speakers into the amp. Both "+" get tied together inside the amp, as do both "-" connections. In this case, with the dual 2 ohm voice coils on your 12" sub, you would wire one voice coil to one +/- set on the amp and the other voice coil to the other +/- set.

First problem is that if you ever have a problem with anything electronic you dont ignore it going on and off or you dont hit it to get it to start working. Thats a true indicator that something is wrong and/or somethings about to break and take everything with it. When it first started to go on and off You could have made sure that the speaker lines were not loose or touching one another or another big problem like this is the speaker wires and how they are ran thru the vehicle sometimes the vibration will rub off the insulation and /or pinch the wire and short it out agains the chassis of the vehicle. The best way for you to trouble shoot this is to first have someone check the speakers and lines. Make sure the inputs are good and disconnect the output lines(speakers wires) from the amp and put a dc meter on one of the outputsw. And have someone turn o0n the power. If theres any dc there for even a spit sec then the amp has blow output devices and probably also bad drivers and predrivers. At this point find out how much your local repair person would charge you for an estamate. or contact Boss at 323.890.3700 ext. 2770 Good Luck
