None of my subs work despite different setups

[mlcantin 32]

So today i turned on my car while leaving class and decided to bump on the way home. Well i couldn't because my sub wasn't working. It was working before class. I got home and hooked up my other working sub which i decided to upgrade from (VIBE slick) and that did not work either. I know for a fact that the vibe isn't blown and my amp tells me when a sub is blown, wired wrong etc. The amp said everything was fine. So i hooked up my old amp (a kenwood) and that amp didn't work either with both subs. I can't stress enough that the VIBE is a good working subwoofer. I checked all of my fuses under the hood and none of them are blown. Neither are the fuses on both of the amps. I took a multimeter to check ohms and my ground was way less than half an ohm resistance which is good. I don't understand why nothing is working. Does anyone have any suggestions as to what may be the problem? Any help would be greatly appreciated.

Sincerely,

Matthew

Get a patch RCA adapter to mini headphone jack for your phone/ipod and use that as the signal to your amp, if it works, you know it's your head unit, if it doesn't you know it's the amp. Could be a bunch of things, maybe as simple as the sub out on your head unit is turned off.

if what source works? and I know my Kenwood amp is good because I used it once and swapped due to lack of power. The subwoofer control on the head unit was turned on. I think something blow when I turned the car on

well you could always run a wire from you + and - to the sub and see if it moves.

Will tell you if you sub is blown or not.

Run a different signal source to your amp to see if it's your head unit failing.

[mlcantin 32]

And what should I use as a signal source?

[mlcantin 32]

and not a chance the amp would tell me if it was blown

[pmureika 31]

Use a dmm and check your sub wiring and head unit. Best tool you need to buy if you dont have one.

[mlcantin 32]

my amp would tell me if my subwoofer was wired wrong plus I know how to wire subs

[pmureika 31]

But are you getting a voltage signal from your head unit?

[mlcantin 32]

haven't checked that. I have a multimeter that can check that. what wires do I need to connect it to

[Jason Witt 65]

Try an MP3 player for a different source, or a dmm to check the voltage in the rca's ran from your head unit.

How does your amp tell you? If you say you know your amp is good and you know your subs are good then its going to be your head unit or rca wire

[pmureika 31]

Your unplugged rca coming from the head unit. It will be a dc signal that should vary.

My amp goes into protect mode for several reasons and it tells you which reason by the number of times the protect mode flashes per second. It isnt in protect mode at all so nothing is wrong with the subs or amp.

What should the voltage read between?

[Jason Witt 65]

What is the preout signal voltage rated for on your head unit? That's where it should measure at.

[pmureika 31]

or use one of these and a Ipod or mp3 player.

Your amplifier talks to you ?!

Do what they told you to do ! Check the rca and the h u. And you'll see

Good luck !

Peramp voltage? Its 2 is what the headunit is required to have

[Jason Witt 65]

Then it should read right around 2v then.

Don't most amps do this?

[mlcantin 32]

Should I plug them into the rca outs on the head unit?

plug it into the rca in on your amp

Procure a mini jack to RCA adapter.

Plug mini jack into iPod or phone.

Remove RCA from head unit to amp.

Plug RCA from iPod or phone into amp.

If it works, the problem is your head unit or RCA from head unit.
