For the last 2 weeks I have been doing my install i have had no music in my car and its really getting to me.
So yesterday I finish up connecting everything, connect the power wire to the battery, and turn on the car, ready for my ears to be flooded with joyous sound.

Instead, i got nothing. I checked the fuses, and none are blown, checked all the connections and everything seems in place and tight. Here is my setup

Pioneer avh-p1400dvd
hifonics 1200.1D mono amp
MB quart onx4.125

I have a 4 awg power wire going to power dist block and splitting into 2 8 awg wires. In the block I have 2 60 amp fuses.

When the car turns on the letters on "HIFONICS" light up, but the power light doesnt. Neither does the power light on the MB Quart. I bought the light up fuses and they aren't lighting up either.

I changed the 2 8 gauge wires to 4 gauge. Tested with mulitmeter and got 14.3 to the ground, and 14.3 to remote wire. However, i received 0 when testing the power. that was all with the car off.

When the car is on, the ground and remote wire drop down to under 1 and still no reading from the power.

I also installed a parking brake bypass that connected with
the ground, the parking brake, and the remote wire.
Would that be an issue?


thanks in advance.

Multimeter before and after these fuses. You should get 12V all around.
Light up fuses wont light unless they're blown.
Tells you it's something with the power wire.
Seems fishy, but I've seen crazier things.
Can you get us the name and model of this bypass?
Good work doing most of the trouble shooting yourself. You're almost there but it's going to be one little thing holding you back.

Also when i take the fuses out of the distribution block, i get 11.91 watts on the power wire. When i put the fuses back in, it drops back to 0.

eh? When you pull the fuses out of the distro block you can measure 11.91volts on the main power wire coming from the battery? But with them in it is 0volts on the main power wire coming from the battery?

Nothing's impossible but that's damned close. Check/change your underhood fuse and battery connection.

sounds like your fuses may be the problem, take your multi meter and go to the continuity setting and check your fuses you pulled out of the distro, and at your battery under the hood, if they are ok you'll have continuity, if they are broken you won't get continuity. One thing though you mentioned you have 11.91 volts @ your power wire when you put the fuse in you get 0 ,where is this measurement taken? is it at the 4 guage wire at the distro or is it at the 8 guage wire after the fuse on the distro block?

I realized i was using the multimeter incorrectly. I was putting the negative on the distributor block. Now im putting it one the area i sanded off on the metal where i put the ground wire.

so now im getting different numbers.

With the car on i checked the power wire at the battery, before and after fuse. both numbers were around 14.4 volts. then i tested the power wire at the amp and it was around 6 volts and so was the remote wire.

does this mean i need a new power wire?

your voltage should be 14.4 volts everywhere you put your probe on the power end of things, your remote turn on lead will be the same thing. Sounds to me your amp has some issues, check the fuses on the amplifier itself just to make sure they are ok as well. If the amp has no fuses, then as I said previously your amp has issues.

swapp the amp see what happens

I have 2 amps and they are both having the same problem.

try this, run a temporary wire directly from your batteries ground terminal to your amp ground terminal and see if the voltage changes at the amp.
