Dammit, it quit working!

[Mackenzie]

For some reason my system is much much much louder at times than others. It can be very loud, then I cut the car off, go in a store, come back, and its no where near as loud as it was previously. It is very strange. Could this possibly be a bad alternator issue? xenon 200.4, and a xenon 1200.1 0 guage ran all the way back, spit down to 4 guage. I am running the 1200.1 with a single 4 guage spit. Do you think I should maybe use both power terminals for the 1200.1?

[mr tibbs]

Are you having problems with just the 1200.1 or the 200.4 as well?

[Mackenzie]

Just the 1200.1 So i guess that means its a current issue. I just ran another 4 guage to the amp so both terminals are used. I am about to test it out..

[Mackenzie]

Also note I am running the xenon at 1 ohm..

[mr tibbs]

What battery do you have, what alt, and how long is the run of 0 gauge?

[Mackenzie]

interstate megatron II its just a basic battery, and my stock alternator is stock( granted it is a decent sized one as its an 02 crownvictoria). The battery is probably 3 months old at most also.. The power I am running should not be enough to effect anything stock I have. Its a measly 1200 watt amp, ive ran bigger amps with stock setups. My 0 guage is probably 20 feet or so long.

[mr tibbs]

Well, did you add the extra 4 gauge to the 1200.1?

[Grim0013]

An intermittent issue like this sounds more like a poor connection somewhere rather than an issue of not enough cable. If it was simply not using enough wire, you would have a consistent problem, not an intermittent one. Could be power, signal or speaker connection. Does the issue affect all channels across all amps? All channels on one amp, or only certain channels?

[smgreen20]

I say RCA connection. I had a Kicker amp that was that way. One of the RCA inputs had a short and it was only seeing half the signal. When you jiggled it it would cut in and out or get louder the not so loud.

Check the RCA inputs on the amp, if nothing there, run a temp RCA cable from the HU to the amp.

In my case even though it wasn't under warranty, Kicker replaced my amp w/a brand new one at shipping costs only. To this day I can not talk bad about Kicker. The amp was a ZR240.

[Bfowler]

yes, it will definitely need the second 4awg run at 1 ohm

[Mackenzie]

I will have to check out and mess with my rcas. Then if that doesn't work, then use some other rcas.

[smgreen20]

Any word?

[Mackenzie]

Still not having any luck.. I used one of my other rca's, and still had the same issue. I mean, its definately loud, but when its louder, its definately audible.. Maybe its not the amp... Im clueless at this point

[Mackenzie]

I am however ready to get rid of the 1200.1, and move on the bigger and better things.

[VW337]

Xe.Load anybody?

Toss a Relay into one of your speaker terminals and fire that beast up at full open then connect it up with a relay, or even throw a toggle switch in for testing, if you get consistent output levels then I'd say the Xe.Load circuit is on the fritz or the subs impedance is right on the border of the power stepping and the slightest planetary alignment changes are effecting it.

[stipud]

Errin, he's running at 1 ohm. You think the amp could take that with Xe.load fooled into thinking it's open? I guess it would be ok for diagnosis as long as the volume is down.

I recall people having the same issue with the IDMax as well. Seems its impedance was just enough to fool the amp into a lower mode every now and then.

[Mackenzie]

To be honest, its very upsetting. When I get in the car, and turn up the volume, I don't know what to expect. 95% of the time though, its not as loud as it has been. Then other days I will turn the bass up, and the bass is literally unbearable to sit in. As for my 200.4. It has been working beautifly. In all, I am ready to get rid of it, and move on to a 2kw+ amp. Will be putting it up for sale when I get off work..

[Mackenzie]

The xenon 1200.1 just quit working.. It powers up with absolutely no output what so ever. No flashing lights, no warning lights, no nothing. Just the blue led, with no output. wtf. Will this be covered? I just got this from the pg f&f sale not to long ago.

[kg1961]

they better or some other people might have the same problem
sale or not it should work more than 2-3 months

[stipud]

PG has always warrantied my gear from F&F sales. I don't think you will have a problem getting it fixed.

[Mackenzie]

Ugh.. Will have to give them a buzz tomorrow. Once its fixed, its being sold.

[Mackenzie]

Out of nowhere, it starts working again. Thenwhen I went into a local store, and came out, and started up the car, no output what so ever. It works when it wants to. Funny thing is that it lights up just fine, but I get no output, then suddenly hours later, I get in the car, and it works. My 200.4 I just sold was flawless, had no issues, and is being ran with the same grounding distro, and power distro..

[mr tibbs]

Did you switch the RCA's around? It's sounding more and more like a wiring problem. Also, check your wires going to the sub.

[Mackenzie]

I switched the rcas, and nothing worked. Like mentioned, the power,and ground is being ran off the same distrobution blocks as my 200.4, that has had no issues. Definately not the sub. Tested the speaker wires, it read 1ohm for final load. why would wiring be an issue if the amp lights up, and the 4 channel right next to it plays normally, and is using the same distro blocks?

[Mackenzie]

I have been doing systems for years, I can't see how I could wire it up wrong, just seems to simple for that, especially considering the other amp works, and this one powers up every time. The ground is solid.
