power but no sound

[shadowm891 2]

Alright here the deal i just got my custom built box in today. so i go to hook it up after wiring my subs up to my new box to my amp and right when i turn on my car and my cd player i hear no bass or music coming from my door speakers. so i go to the back to check both my 4 channel amp and my sub amp and they both show power like nothing is wrong just no sound.

ok, DON'T PANIC!! hehe

Lets just try some trouble shooting steps and see where we go from there. This is probably do to something very small. Ok, we may need some additional information from you, such as:

Was your door speakers working prior to subwoofer installation.

Have you checked your fuses, ALL fuses.

I'm assuming 2 amps?

Have you checked ALL RCAs, how many are you using?

What are the make/model amps your using?

Power with sound sounds to me like an wiring issue, plain and simple. I think there maybe a few loose RCA connection, or wiring isn't connected properly. What HU do you have? Some H/U's have the option to turn on/off the outpputs of those RCAs. Like a sub on/off. Also, prior to connecting your new subwoofer enclosure, was this high/mid amps connected and working properly? Have you disconnected the speaker wires from the cd player's harness? Also, on those amplifiers, check to see the status of the Master/Slave option if available.

I think I've covered a lot of areas for you to check, if none of these get you going, then you might want to consider replacing your HU has you may have a unit with malfunctioning RCAs. Let us know what happens.

Was your door speakers working prior to subwoofer installation. ( sorry don't understand this question are you asking if my door speakers work fine before all this happen )

Have you checked your fuses, ALL fuses. (yes i have i check the one under my hood and even on my sub amp my 4 channel amp is a old school rockford fosgate so it don't have fuses on the outside)

What are the make/model amps your using? ( sub amp pyle plad3300d , channel rockford fosgate dsm 4040)

What HU do you have? ( eclipise cd5030)

Also, prior to connecting your new subwoofer enclosure, was this high/mid amps connected and working properly? (Yes)

Have you disconnected the speaker wires from the cd player's harness? ( speaker wire's as in what sub or 4 channel amp)

Not sure if this will help but i just went outside to check my stuff and i go to turn my cd player on and i just heard a pop coming from my back speakers which are hook to my cd player and not the 4 channel amp and each time i swich over to the radio or my usb flash drive it makes a popping sound just 1 time.

Good news both my amps are fine had a friend hook em up in his car and they play fine but the problem still not fix.

So you presently have no sound from either the speakers connected directly to the headunit as well as no sound from the amplifiers? Is that correct?

[shadowm891 2]

Im getting sound from the back speakers since there hook up to my deck. but the subs and the front door speakers I'm getting no sound.

well i found out what my problem is i am lacking voltage for both my amps. i ran a voltage test to both amp while the car was running and the music was on and they were reading 6.8v each so i went ahead and check my 2 blocks that i use for my power wires and ground wires and it was reading the same thing 6.8. so i went under my hood and took the + wire and hook it to my power wire that's connected to the battery and the - wire and ground it on the body of the car and got a 14.2v. well now that i know the problem has to do with not enough voltage going into my amp's what would i need to do next.

I'm not completely sure on what to try next. Maybe, try elementing some of the possiblitys, for example, try to connecty the amps bypassing the fuse blocks, maybe that could be the issue. But for both to bad, idk, find than unlikely. Ummm, How do you have your amps grounded? May want to check that. Try to make sure there isn't any corrosion on you cables.

I fix the problem my main ground that bolts to the body was bad so i had to replace it.
