kx2500 going into protect..

[aaron7114 10+ year member]

Crap son, you are running a 2500+ watt amp off 4 gauge (and 8 gauge) wire, a stock alt, and only 1 battery?
What did you expect to happen? The amp is fine. You need to beef up that electrical system BIG TIME.

I can get my zx2500 to kick into protection mode when I'm burping the amp with the car off (2 batteries, 4 runs of 1/0), but when I turn the car on, I have no problems at all. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Its not a stock alt. Its a tad bit bigger than my stock alt. Its brand new too. Just got it about 3 weeks ago.

Like I said I will soon have some 0 guage wire that I am going to run directly into the 2500. Then 0 guage for the ground as well. I have absolutely no where to put another battery.

How much bigger than stock?

1/0 will definitely help, but it may not alleviate all of your problems. You are demanding far too much current for your electrical system to handle.

120 amp

120 amp

120 amp isn't going to cut it unless you get a 2nd battery.

sorry but i loled at you when you said you had a 120 amp alt. on a 2500.1..//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

I think its electrical. Kicker has never been known for very efficent amps to begin with. With 2500w a upgrade to the electrical system is a must, otherwise it wont even peform like it should let alone how you want it too.

I ran a 140amp alt in a 1993 Buick Lesabre for a Mtx 342 on my highs and a Kicker ZR360 bridged wired at 2 ohm mono on a pair of Comp VR. My stock alt was 105 and could not handle the load even with a bigger battery up front.

should I just get a zx1500 and run it at 1 ohm?

I am going to aaronmiillers house tomorrow and we are going to hook it up to his vehicle. He has a 200 amp alternator and two extra batteries in the back. He also thinks he can get it workin in my car, if there isn't anything wrong with the amp.

no, in order to have power, you have to feed it. It's like having a race car and running on 4 cylinders if it's a V8. You need voltage, voltage is king. In order to keep voltage, power wire is a must.

If you have a 2500 watt amp, and under feed it, you will never see 2500 watts. Now given all the voltage you need, you can see that, plus some.

ZR amps are a regulated class A/B amp, not like the more effecient class D amps.

well I could handle not being able to get the full potential out of it. Its like that with every amp. Not enough power you dont get all the watts. I would just like to be able to crank it without it going into protect.

We will see tomorrow if voltage is the key. We should get it working just fine //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif .

I sure hope we can get it workin.

It is a fact that very low operating voltage will damage an amplifier. You should be glad it goes into protect or you probably would have broken it by now //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Your planned upgrade to 1/0 is a start. With an amp the size of the 2500.1 I would suggest a ~200 amp alternator and an extra battery... like a Group 34 Optima or a Deka Intimidator.
