Do i need to replace my HU

Okay about 6 months ago i hit the power cable on my amp and it fried the amp... i had to turn the gain way up to get the same output voltage. Anyways i didnt think much of it but i just spent 610 on a new sub and amp and do not want to mess anything up. Last week i checked the preout voltage and it was at 2.3v... its suppose to be 4. (deh-p590ib) Should i replace it. Do you think theres anyway it will cause amp clipping or distortion to ruin my speakers/amps/subs. I have used my system atleast 30 min a day for the past 6 months like this without any damage and there is no noticeable distortion, but i really dont want any of my new stuff to **** up a year from now

thanks

You'll never see 4v until you hit the loudest the head unit will go. And by then, you'll be clipping the balls off out of the amplifier.

i tested the voltage everywhere.... it was always 2.3 volts until i got to around 50/62 where it dropped to 2.0 Im guessing it was clipping.

Not that you should ever run your head unit like this, but turn up every setting you possibly can on the HU. Then measure voltage.

Well the ipod loudness was all the way up... with it set at normal with the gain all the way up i couldnt even get correct voltage. Before with it on +0, gain was under half, now with it at +4, the gain is 2/3rds
