can’t get an amp working arg

Okay so I'm having a lot of trouble getting the top to fire up.

The bottom amp is a 4 channel Interfire amp that runs 175 X 2 into 4 ohms which i have wired up to the 6x9's.

The top amp is a Bazooka amp 70 watts x 2 into 4 ohms which i have wired to the subs. This amp i cannot get to work (Blue circle)

My signal source is an ipod (represented by the PSU koozie). The yellow circled source is output to the car's speaker system, the pink circled source is output split to the two amps. Now here is the weird issue at hand.

-The interfire amp works regardless, when I fire it all up it's on it pushes the 6X9's great and has no hitches regardless of what goes on.
-When I just run signal from the ipod to the amps and don't include the car system (yellow input unplugged) both the bazooka and interfire amps run fine at full strength.
-When I plug in the car system to the ipod source the bazooka amp's protect goes from green to red after about 1/3 volume added to the car system and cuts.... the interfire runs fine.
-When I pull the power from the interfire and have just the bazooka running it has the same issue. The moment i try to run the bazooka with the car system as well, the protect goes off when i reach about 1/3 volume on the car system.


I'v tried adding another ground to the battery and adding another ground to the bazzoka amp. I have reached the extent of my knowledge and internet search ability on this one and could use some help on this one.
Thanks in advance!

If you used a line out converter for signal from your factory head unit, ground the brown wires on the Line Out Converter.
Or if you have a Pioneer radio, https://bcae1.com/images/rca/temporaryrcashieldrepair.html

Signal is coming from the ipod into the RCA connector on both amps.

While i dont have a response to your question...I havent seen a "natty lite"(natural light) in a long time...I bet if you drank a better beer...It would be comparable to staying at a holiday inn express...!? Then you wouldnt even need us here...!

Go slow and drink lots of water...Procrastinators' Unite...Tomorrow!

our strategy is usually bring your own 6 pack than 5 cases of bud light than when you can't taste the beer anymore drink natural light... saves a good bit of money! Hence the leftover in the back.

first thing you need to do is disconnect power from both amps get a power .then take a power spliter which would be a 4 or 8 gauge inlet and 8 gauge outlets for both amps.ground your bazooka and interfire amps to the body of your aztech.then both of your amps will turn on

really dude? Not that I don't appreciate the advice but c'mon you don't think i did that stuff? : -)

I suspect the signal level from the iPod is simply too low for that amp, although I am surprised the amp goes into protect mode.  In any case, you probably need to adjust the gain (input sensitivity) of the amp every time you change to the iPod input (and then remember to adjust it back when you switch to the HU.)  A much better solution is to use the car's HU and run the iPod through an aux input adapter instead of connecting directly to the amps.

I do agree with the beer comment.... better beer is a must!

 dude do you see that install??????????????? thats it,im logging out

Would a line driver be a possible solution, as previously stated the signal level from the ipod is too low and it is also being split thus reducing it further.
