headunit cut off at full alt output?

[x91evo 10+ year member]

Hey hows it going everyone,

Well been driving around for a while with my system in for temp stay.

-320A Mechman @ 16.5v charging (big 3 all 0 gauge)

-one Xs power d1400 (as of now)

should also add my one battery failed a load test, so this one will need replacing soon enough

-one run of 0 gauge for power

-one run of 0 gauge for ground to amplifier

(grounding to chassis for temp, would not allow amplifier out of protect mode)

-Kenwood Kvt-514

-Memphis Mojo 4000

-two 18" jugs @ 1 ohm

signal on amp is around 1/3-1/2 up

(I would try to lower it but my rear hatch lever has manager to break some internal linkage from the vibrations so I would like some ideas first)

and at the headunit it is at -8 for the bass.

bass boost is 1/2 way up but i rarely touch the gain knob

(but it will play at idle up high)

The Kvt is currently connected to two stock speakers

(possibility of a short maybe?)

but every other unused wire has been capped off

While at idle the subs can play at full volume and they sound great!

but as soon as I increase the engine rpm the head unit will cut off.

I contacted Kenwood and they insured me the headunit can handle these voltages,

and Kenwood asked about my signal levels.

Before this problem persisted the headunit would continuously cut off at anything above idle IF the ipod (that is connected through a manufacturer supplied cable)

would only allow for the ipod to play at maybe 1/2 the headunit volume capable and then would shut off at anything above that. As where with a CD, the headunit could handle higher volume levels.

Somehow the Ipod problem corrected itself,

I should also add right before the headunit decides to turn off, everytime my "ABS" light comes on. And this has happened previously ONLY when a battery cable becomes disconnected.

Or when the vehicle is forced to accept more amperage than it is capable of handling.

(So that would be very similar case with this problem it seems like?)

so my question is

How would it be possible to use the full potential of my alternator?

It seems as if anything above idle amperage, the headunit will not accept?

Whether it be more batteries, lower my signals or any suggestions at all

Any input would be greatly appreciated! thanks

So your entire car is running at 16.5v? I have never attempted to raise a cars charging level but it seems like that would be rough on the cars electronics? I'm sure someone will chime in with aftermarket alt exp.

16.5v is probably not agreeing with anything electrical in your truck. If you don't have an isolator and 14v batts, lower charge voltage to 15.6v or lower. Preferably 14.8-15.1

no problem with anything at all in my Jeep Cherokee with the voltages,

I had the Jeep at 16.5v charging 14 resting about 2 months before any speakers went into it

And I drive the Jeep everyday

Im feeling a troll going on here..Im surprised that all your electrical hasnt been smokin/melted the protective sleeves off all your wiring:repsthrs:

haha so I take it I should have more runs and batteries?

this is my first time installing something high power

 

[x91evo 10+ year member]

stock ecu can handle 19v i hear..

there are plenty of cherokees on 16+ charging

Bump for some info?

This is a serious question!
