Amp Is Soposibly 2 Ohm Stable. But It Cuts Out! ? Wtf?

[warren84 10+ year member]

Ok I just got a new battery for my car and i can run my system fine @ 2 ohms without any lights dimming now with is a big PLUS! but now after about playing music with nice bass for about 5 mins my amp cuts out and i have to turn off the switch i hooked to it and put it back on and it works for another 5 mins and then it cuts out again... my amp is a Kenwood KAC-7201 (2chan 800watt).. I have it bridged @ 2 ohms.. Id really like to be able to keep it this way for the simple fact that its really good quality bass compared to having it on 8 ohms like i did befor... everywhere i look except 1 place says that this amp is 2ohm stable... but i doubt it is if its cutting out like it is.. beh i cant take this SHlT n e more

I suggest you check all your wiring again. You may have it seeing an ohm load thats under 2ohms. Im not trying to doubt the fact you dont know what you doing, but there is still a possibility that you could of messed up somewhere along the way. And is your amp really hot? Or is it just cutting off?

The reason your amp is probably cutting out, in fact I would bet my life on it, is because you are bridging it at 2 ohms. The amp probably is stable at 2 ohms, but I have seen very few amps that are stable at 2 ohms bridged. You are going to have to lighten the load on your amp.

hmm maybe i should just put it back on 2 channel 4 ohm (150watt rms per speaker).. since thats the RMS for the speakers n e way.. its not that big of a drop in sound... and no the amp isint really hot, it also has a fan on it, and its cold as hell in my trunk cuz its winter, i live in michigan.. so im definantly putting it on 2 channel 4ohm.. untill i get a new system, it was only $360 for the speakers + amp n e way.. its my first system..

and for whoever said i might have wiring wrong, i doubble checked it and i have both positives goin to positive and both negatives goin to negative (bridge)

I don't believe thats is bridged...Maybe i'm misunderstanding you but bridging would be only actually plugging two of the wires into the amp, and you wire the subs in a different way. So if you're doing that you are running your subs in stereo, and they are probably barely getting any power at all. What voice coil config are your subs?

dude it is bridged.. BOTH postivies from each speaker are going to the LEFT CHANNEL POSITIVE ON THE AMP.. and BOTH NEGATIVES are going to the RIGHT CHANNEL NEGATIVE ON THE AMP.. why would u think its not bridged? im not a moron

 

[warren84 10+ year member]

And The Amp Switch Is Set To Mono/bridged

 

[warren84 10+ year member]

ppl dont even gotta reply any more... the simple fact of the matter is... i hooked it up bridged 2 ohms and it is not going to work, the amp overheats.. end of story.. i ahve it hooked up fine and thats all ppl can seem to do is tell me to hook it up right... behh!!! im just gonna stay with 2 channel/150watt per channel 4 ohm... i guess u what what u pay for and since i payed $360 for a amp and subs i got ****ed... peace

First off, you got hosed. Shouldn't have paid more than 160-170 bucks for that amp, I have found it for 130. Anyways.

The amplifier is NOT 2 ohms bridged stable. 4 Ohms bridged stable or two ohms stereo. That's your problem. Well, and your attitude.

i hate it when you try to help someone and they yell at you

I don't understand his problem. I posted days ago that his amp could not handle a bridged 2 ohm load and I guess he ignored it.
