I just bought the zx700.5 amp and got everything all wired and wired correctly. I had driven around with only the rear speakers for a day and that worked fine at high volumes, the next day I worked on the front right speaker and got that wired in, that also worked just fine at high volumes. I then proceeded to wire in the front left speaker, once I wired that and mounted it the amp started to go into protection mode if turn up about about 60% volume. I tried unhooking the front left speaker to see if it was a pinched wire somewhere between that speaker and the amp, but now it cuts out with it unhooked. Can anyone help with my problem?

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
When an amplifier shuts the Bass off that means its going into protection mode otherwise it will burn out the outputs. One way is to turn your gains down, Pioneer amps are not the best amps for bass out there, they are more for car speakers, I personally wont use a pioneer amp to run my subwoofers especially if they are hard driven subs like JL , Kicker Solo's and MTX subs. But for now just turn the gains down to 3/4 and that should help u, you can also install a fan to keep your amp cooler, if this never happened before in 5 yrs and now it does then that means your amp is just tired and the inside components are overheating easily, thats common with Pioneer and Sony amps.
It could be your wiring as well. Sometimes, when speaker wire gets cut and grounded, like your factory wiring to your door speakers or you tap into facrotry speaker wires to add more, the load on your deck increases. When the volume gets to a certain level, it will cut off because of the heat produced to maintain the load.
The reason it used to cut-off at 60% volume as you said before, Is probably due to the "protection circuit mode" being tripped.
You can try resetting it by turning off your CD player ,removing the Batt( + ) and Gnd ( - ) terminals from the amp for a short period. Reconnect them Allow the amp to receive power but not switch on (keep cd player/remote power source off)
If you dont know how to wire the CD player to control the amps power status , the easiest way is to connect the 'power antenna' or similar low voltage throughput wire from the head-unit to the amp's Remote terminal.
My old amp did the same thing ,and would need to be powered off/on before resuming sound output, sometimes I had lots of trouble with the protect mode staying on , even with little or no sound output from headunit.
you mean that the SUBWOOFERS connected to the amp cuts off and come back on randomly?? did you bring the SUBS level to a high volume ? i suggest to check first the value of the speaker (ex. 4 , 8 , 16 ohms ) matches the same value with the amp . second , hows the subs connected , in series ? or parallel . you will need a multimeter for this task .
