Eclipse headunits (avn 726e specifically) and preouts

[pimpnyou204 10+ year member]

My avn 726e seems to not be putting out the rated 5v it's claimed to. I read a review on it saying the unit would do 5v unclipped at full set flat. Then I read around about the sub preouts not doing near what it says so I called Fujitsu and they said it would do 5v at 80.

Anyways I did my own tests with my dmm put on ac and 200 1k tone. At 80 I get 4 in my fronts and 4.2 in my rear. Now my sub setting goes -6 to 6, with it at 0 it does a whopping .7 **** if I know but I put it to 6 and it gets the 4v.

Now obv it's not doing the 5v set flat. Now my questions are WITHOUT a o scope..

1) do u think it's clipping on full or just once u start putting loudness and changing treble bass etc?

2) how much do u think the sub out is rated to? And if it's less should I use a rear preout to bump it up?

When u find out let me know my eclispe says its 5v but based on the volume lvl have to turn to and the amount of gain I have to turn on my amp I am guessing it might be doing 2.5..

Well I have a arc audio ks 300.4 and it's 4v unclipped all the way and at 70 volume it don't even get from freezing lol but at 74 it gets a lil warm. Look to see if any others have this issue with eclipse units and more so the nav units.

wow thats strange... maybe your ground is iffy and its not getting a good current?

i just swapped my previous unit that was rated for 4v for another rated at 4v... huge difference.. i guess it varries... this unit i cant go past mid volume (20/40) the previous i went (45/62)

Ok weird thing.. I take the voltage out the RCAs at my amps and I get 4.6... Now when I take it out the actual headunit preouts I get 5.5 both at full volume. This is with all 3 RCAs I use so I doubt all 3 could be bad. My RCAs are also kicker so they should be decent. But any thoughts as to why their like a whole volt less after they go thru the RCAs?

A whole volt less after going through the cables... does resistance ring a bell? That'd be my guess is that by the end of the RCA's, the signal is not as strong.

Well they are rather long RCAs (16ft) but I have seen much longer and that's quite a drop in voltage.
