I have a Cadence FX500 Connected too an Alpine player by 3 RCA cables, and " front speakers 2 back and 1 Sub. it's a 5 channel amplyfier. When I play music it works just fine then it suddenly goes in protection mode afther a random amount of time varrying from 2 secounds too 5 hours with adjusting on all the crap but it still goes in protection and when it does it wont work at all for a while. it's not hot at all, and the Player keeps going, checked for short circuted wires. have no idea what too do. Can this be anything with incorrect Input Gain levels and/or Hz setting on the Amp? or mabe bad grounding.? apriciate any help.

Sorry,after rereading your problem,I gave a wrong answer.Do you have the deck sub RCA pre-amps connected to the amp,then the wires from the amp to the sub?If you do,you need to check what the sub and amp are rated as such as,peak or rms.They are 2 completely different meanings.Greg
I would strongly recommend that you get a 5 channel amp that puts out 75watts rms per channel that will deliver between 200-300 watts to the sub channel. I use planet audio amps myself and they run strong all day every day-maybe you could look at a planet audio vrx 600.5(5-channel) it throws 100w x4 and 200 or 300 to the subs depending on the resistance of the sub. Good luck
hi hit's very easy,
1 - you need to pass a wire gage 8 from the positive pole of your batterie from the front of the car to the back and plug it in your power amp at batt+ or + or batt
2 - take and other cable gage 8 and ground it at the body of your car make sure that is no paint when you plug it and plug the other cable in your power amp at the grn plug
3 - pass a other cable gage 18 to the radio to the back or your car. plug it to the blue radio cable marcked remote or rem and p;lug the other side to your power amp to the rem pin
4 - then pass 2 rca cable from the radio to the back of your car the radio side plug it to the sub or rear output rca cable and the same thing for the power amp
5 - you sub wouffer if you have one sub plug the negative pin to the negative bridge output and positive bridge output power amp. if you have 2 speaker do the same thing but not at the bridge place
Although amps with 5 channels are pretty rare, you can get one. Alpine, Boston Acoustics, Infinity, JL audio, MTX, and Polk all have 5-channels ranging in price from around $350 up to around $1,000. The Alpine PDX-5 will output 75X4 watts RMS for the front and rear stereo channels and 300 watts to the mono sub channel. It is priced at $599.99 at Crutchfield.
Overload maybe. If the amp is run at an improper impedence, the amp will shut down. If you are "CLIPPING" speakers / subwoofers the light will blink to indicate a hard clip . Example: 4ohm/2ohm stable amp with 4 ohm subs wired at 1 ohm.
This should work if channel 3 & 4 are bridged at 4 ohm.
channel 1 should be stable at 2ohm
channel 2 should be stable at 2 ohm
You can hook up the right side speakers together ( + with + and - with - ) . same thing with the left side. this will give you 2 ohm each channel. this will cause your amp to run hot (this might be tuff on the amp). It will give you right (2 speakers) and left ( 2 speakers ), no front and rear adjustement if you need to balance your sound. I think you should be better buying another amp for your sub and take your 4 channels for your 4 car speakers. this amp as a rca output that can feed the other amp ( sub amp ). it is possible to do it.
The FX500 is 4 x 75 watts clean and 1 x 500 watts RMS @2 ohm mono. What subs are you running and what are the ohms per voice coil. Single or dual voice coil. By what you said (not getting hot) sounds to me like the load istoo much. Let me know.
