turn the subwoofer level up on the headunit and reset your gains.
I had a similar problem in my buddies WRX with an alpine unit. It wasnt providing its rated RCA output voltage.

agreed, settings have to be relatively high for lower end alpine hus

From what I've read the sub out on Alpine HU's need to be set to their highest level because they are designed to reduce volume, not increase volume.

Which is why I said he needs to set his sub level to +15, the highest level on alpines. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

ok great that is the information that is good to know.

i had my subwoofer setting to 0 while setting my gain.

and volume was 26/35

i will try this tomorrow and hopefully get better results.

and then just leave the setting at +15 right.

You should get MUCH better results.

But be careful with the volume. When you set the sub output to +15 I would possibly turn the volume down some unless 26/35 is your normal listening volume.

Yes, on alpines the subwoofer control varies the premp voltage, you have to put it on +15 to see full 2V.

On 0 it is like 0.3v

You have a stock alternator, a single battery, and no big three. I would hardly call your electrical satisfactory.
What vehicle is this?

x2.

06 honda civic. and the wires for big three are coming early this week. from what i have read.. this will be enough to run the amp.but thats not the point. i was not running the amp. i wasnt playing it? so why would it give me such a low voltage?

Umm, your stock alt is 60A I believe.

And you're trying to run a 150A amp on it. with 8 AWG alt wiring.

and you think you're electrical is satisfactory?

 

[tacovic 10+ year member]

if you would have read you would have seen that i am upgrading alt wire as as well as all other big three wires with 1/0 next week.

i am going to see if i can run it ok and if i cant then ill throw a batt in the back.

ok guys i redid the tests today with the subwoofer setting on +15 and it was a night and day difference. i got my voltage of 56.54(1600rms) at only 40% gain

thanks to the people who helped me out

Sometimes it's the little things that can mess up the whole works.
