Rockford Noise new facility - Clarion DXZ948RMP

josesony68 · 6th October 2011, 10:41 PM

Hello everyone, I recently completed my installation of audio on my Mazda3, 2005, and the sound for me is great, Clarion cd radio, amplifiers Rockford, Infinity speakers separate ways, subwoofer Rockford, good wiring, Optima battery ...
The only problem I have is a small and annoying engine noise when the volume is 0.
Should I replace the RCA cables, for a better quality?

Did you try reducing the gains on the amp?

josesony68 · 7th October 2011, 03:25 PM

mmmmh .... No, profits are now at the halfway, but I will try to reduce them, to see what happens.
Anyway, this cd has RCA auxiliary line tv, y. ... Tickets now they are not protected by their rubber caps, can be in contact with something and causing the noise?

If the shields were in contact with a grounded metal surface/object, it could cause a bit of noise but the noise would likely be intermittent and would vary when passing over bumps in the road.

yes, that's a very good point! but the noise is continuous, but still sounding skip potholes.
I will try the best to lower the entry level, but now I can not, when you do, tell what happens.

I tried to lower the input level, and then the noise is significantly reduced, but still you hear something, I have to put his ear to the tweeter, to hear something.
Then, the amplifier can be a problem?

Perry Babin · 7th October 2011, 10:42 PM

Is there really a problem if you have to put your ear on the speaker?

I'm assuming that the gain setting allows you to drive the amp to full power.

josesony68 · 7th October 2011, 11:04 PM

No, really, really, is not a problem, just a bit annoying when there is no volume, but that will not ever happen, there will be some volume and not hear the noise.
Maybe I'm a little gourmet, trying to find the perfect sound.
Perry Again thank you very much for clearing my doubts.

Just one more question:
I have seen in the journal volume of Rockford, that increasing the alternator cable section,
0.7 V earn what is there in this?
