Low preout voltage?

[rockFord_Expedition]

adjust (turn down) the sub level on the headunit to match the output of the front amp so they are both around the same volume

So instead of one part sounding like ass, make them both match?

He needs to find someone or get an o-scope or DD-1 and find his max clean output. You start that process with your sub out turned all the way up and back it down as necessary.

The headunit clips at 38/50. I work at a manufacturing company that makes radio broadcasting equipment. I borrowed an old school oscillator scope, not a portable one. But the guy that uses it there to set up the broadcast consoles helped plug it up and everything. As reading online it said to set it just below clipping. I just gave it just a little extra space since I tend to have music that varies in volume quite a bit.

and side show if i turn down the sub level, I hardly have any voltage on the speaker out and the subs act like they're not even on. So matching volume to the front would just be no bass with hardly any highs at max volume. Lol.

the 2 ch amp is an older sony xplod 180 rms per channel is pushes the subs just fine with sub level turned up. The mono amp is hifonics brz 1200

[MrSkippyJ]

what headunit?

also, did you test the output of the front AND sub?

[cyph3r]

headunit is sony cdx-gt34w

and you mean test with oscope? no only did the headunit, i just set the gain on the amp with dmm and under set it by a few volts

[rockFord_Expedition]

Did you set your rear output to full range instead of sub, and plug it into the front input to see what happens?

I had the same problem, I had a really nice alpine navigation deck I paid 1000 for a few years ago and didn't realize it was only 2v out. It still worked but not as loud or clear as some higher voltage decks I had. I would get an epicenter, or a new deck if I were you.

[cyph3r]

I haven't tried that. Didn't think it would make a difference. I can possibly try that tomorrow.

[MrSkippyJ]

You need to test the output of your headunit, both front AND sub outputs.

2volts is PLENTY for OPs application. There is zero reason to worry about more output voltage. Unless the deck is complete shit, in which case it's still not a voltage issue.
