Im lost

System not getting loud enough. I can turn the volume all the way up without distortion and it's not loud at all.

Current setup

Hu: Pioneer 980bt (5v preouts)

Front Stage: sr6500

Amp: Alpine MRV545 (digital gain set to 4v)

Sub: sr124-dvc

Amp: Alpine MRD-m1005 (digital gain set to 4v)

Before the 545 I had a 345 and had the same problem. The amps are getting 13.8v consistanly. I tested the speaker terminal and it only reads .7v with the volume turned up to 45 out of 62. Thought it might be a rca or hu issue. So I hooked up my buddies deck and a different set of rca's same problem.

Could it be bad grounds? Any ideas please let me know.

turn up the gains?

i've played around with those amps alittle bit. Honestly turn the gains up to 2 volt or even 1 volt. Now its up to you to make sure it isn't clipping though so set it to whatever volume that would be the loudest that you will listen to it and check for clipping from your subs and then your speakers.
