diamond audio amplifier problems

OK, I have seen this problem many of times and it is your a voltage drop. By any chance do you have a power cap or a upgrade alternator because what it is doing is when the bass hits, it draws so much power from the car. With a power cap and/or an alternator of 140amps or more it will stop the blinking of the protect lite on the amp. I know you said that it was at a 1 ohm load so that means your amp is giving out 1000rms to 2x 500rms speakers right. You have them in a (parallel/parallel) hook up then. If this is right, then that is what you are going to do, is to get a power cap or something to take the spike of the amp when the bass hits. If you have a power cap then you just might need a bigger one. Every 1 Farad = 1000watts max. Let me know if this helps. Have a good one. If you got anymore questions for me let me know.

Ok have you measured the voltage at the amp while playing?  Try this and let us know what the voltage is when the protect light starts to blink.  As stated above this could be a voltage problem.  Now adding a cap will not solve any of your problems, this is just a band aid and could cause more problems down the road.  With a upgraded electrical system there is no need for a capacitor.  Do you have your big three upgraded?  If not this may be a good place to start.  Read the sticky on big three upgrade.  Also what gauge wire are you running?  Are there any more amps running on your system?  Let us know what the voltage is while playing and then we will ne able to better assist you on getting this solved.

i have a kinetik hc800 battery as my second battery so the voltage is fine and 4ga power cables like the amp needs thats the biggest it can take toopioneer 4800mp h/u

Do you know the voltage is fine did you actually measure it?  A battery is just a storage device, it stores energy does not create it.  Adding a second battery will do little to nuthing if you cant supply the power being drawn.  Power being supplied comes from the alternator.  Is your big three upgraded?  If not chances are the the current grounds from chasis to engine are 8 gauge or smaller much to small for the type of current you are pulling.  This could solve your problem, but you have to physically measure the voltage while playing at loud levels to determine this is the source of the problem.  As far as everything else you have told me, such as your load on your amplifier, and the correct cable size everything else seems fine.  If it isent the voltage problem then you might want to consider sending it back to Diamond and getting it replaced or looked at...

Yeah you don't need the other battery but it helps with the voltage draw from the amp. It makes it so the amp does not see least the 10volt. 95% of amps see 10 volts and go into protect mode. He needs to up grade to a bigger alt. and maybe his wire is it less the 4g. But after putting that all together the other battery or a bigger battery would be a good idea for a great system. I have my self in my van 800ca in the front and 1000ca in the back with a 1 farad power cap with a 0/4 wedding cable going from front to back, and a 140amp alt, NO POWER LOSE IN MY SYSTEM AT ALL.

He didn't say the amp was shutting down, just the protect light was flashing. Series the woofers and see what happens. Running 1 ohm is just flat out LAME. More heat and more current for a few extra db's. If it's rated for 1 Ohm or not, the actual Imp. might be a quarter of that. If the problem is voltage you must make energy, not store it. A second battery is a waste of time and money if you have no way of charging in. A HO Alt. and the Big 3. Stiffening Caps do have a time and place, but very few people know when that is. 95% of time it's some idiot just wanting to sell you something.    "I have a kinetik hc800 battery as my second battery so the voltage is fine". Did you measure this voltage or are you assuming? You should have 1/0 AWG linking the two. "Yeah you don't need the other battery but it helps with the voltage draw from the amp. It makes it so the amp does not see least the 10volt". This statement make zero sense. The voltage is not drawn from the amp. The amp sees whatever voltage is between power and ground. If the voltage at the second battery is 13V, the voltage in and out of the Cap will be 13V and will be 13V at the amp. If you can't supply the rear battery with the correct charging voltage, it is just a load on your electrical system. What every energy you use, must be replaced. Ragsports advice has been spot on. 120db with a bowl of chili.

thanks for the help everyone,the voltage at the amp never drops below 13v but ive only played it half way,and the amp is regulated so anywhere between 11 and 15.5 volts doesnt matter,and the second battery helped a ton for me the rpms used to drop at this volume and lights dimmed a ton but now they dont anymore at all,even after an hour of playing the voltage of the batterys after the car is off is 13v,so charging them isnt an issuepioneer 4800mp h/u

i asked a local shop they said its likely that it sees a bit below 1ohm...cause as the coil moves the impedance fluxuates a bit because thay are dual voice coil,it does change as the subs move we measured it as they played,and they said it should be fine and to wait and see what it does after the break in period,so idk that may be it,asked diamond they had me check everything and said maybe get it bench testedpioneer 4800mp h/u
