Hey guys,
After having a tech look at the amp, turns out it needs an estimated $300 to get it fixed properly.
So i am leaving it unfixed.
Not a great first impression of phoenix gold

Thanks guys. I'll let you's know how the 50htz sin wave measures on my multimeter.

Big thanks guys. I'm learning alot about a topic I didnt know much about. WOW this is great learning.
I'll download myself a 50htz from where?? I read it has to be CD format not MP3. Where are these in that format??

It was set to 200 on my V part of multimeter. It doesnt actually say AC but the positive plug isnt in the DC hole so I assume its AC

What do you mean Brett?? by "you can't prove the gains". How does your 900.1 d go?? I picked mine up for $300 AUS. Now know why

The amp stayed at 31.7 volts from zero gains all the way through to full gains. No change whatsoever.
At soon as sub was hooked up it dropped to 1.8volts

Oh yeah and quickly,
How do I measure the output with a mulitmeter??

Thanks Bret,
I appreciate what your saying.
Would a more powerful amp be a better option??
And Does this mean the sub could get damaged if the amp is doing what its doing??
So you believe from whats been going on that its not a problem with the amp??
Thanks

By less powerfull I mean a 400rms dual 4ohm sub wired at 2 ohm. My current head unit is a clarion 576USB and has 6v preouts and it was tested on an Alpine unit. I dont understand why its clipping at only just over half gains. The sub is not even getting loud before it decides to switch off. Then as ...

Hey, I have 6volt preouts on my head unit. I took it to some guys today to look at and its doing the same thing. Doesnt seem to go into protection as the blue light stays the same colour. I've tried reading the link but to be honest, i still can't understand the jargin. The amp did the same thing on...

Hey guys, I recently purchased a Phoenix Gold QX 900.1D to run an Alpine Type X 12' sub. I installed it today running 4 gauge and all went to plan. Then I went to set the gains. As I cranked it to just over half gain it started clipping (momentarily flicking the sub on/off). The sub is wired at 2 oh...
