hello.

i drive a 87' chevrolet nova.

I had my stepdad put in 2 10 inch kenwood typhoons, and 1 sony amp.

We wired it and it all worked. It worked for about 1.5 years and just last week i took a hard left turn and it made like a scratchy sound over music then died.

Not the music, just the subs. I have no clue what it could be!

i took my subs apart and all the wires in the subs them are fine.
My amp's power light still comes on.
I think it might be the amp's wires that came loose or something.
The wires into the amp is fine.

I have no clue...and wanna look at it this weekend.

Any help would be appreciated!

Maybe you can look at the wire inside you sub box, sometime they get loose on the subwoofer with all vibration.

Check your RCA cables. They might have gotten pulled if everything wasn't bolted down properly.

I took apart the sub box yesterday.

I fixed all the wires inside (all were working) but just in case and still nothing.

@Durwood
This is kinda n00by but what are RCA cables?
Like power, ground etc.?

Thx.

RCA cables are the ones that run from your headunit to your amplifier. They are what plug into the white and red jack on your amplifier.

Jordan34

okay.

I checked those too.

i took off the door things (where they run under) and all the wires are fine, not cuts scraps, anything.

The back of head unit, they are plugged in.

Could it be the Blue cable... i think its called REM? It goes to the deck from the amp.

maybe?

the blue might be remote. If your amp turns on when your stereo is turned one then its fine. the remote wires purpose is to tell the amp to turn on when stereo is on.

hmmm they seem to be fine.

Could they be broken from like people stepping out of my car (cause the cables run under below the door.)

How much would a new RCA cable cost, just the cable.

If you have a portable audio device that play sound out of a headphone jack, and if you have a headphone to RCA connection type cable then you could test the amp to make sure it still works. Just play your portable audio device with the RCA cables connected to the heaphone jack. This is a good check because then you don't need to run new cables only to find out that wasn't the problem.

If you get sound coming out, then your RCA cables in your car might have gotten stretched and need replaced. Cheap 15' ones under $10 from walmart/radioshack. Better ones $20-60.

I attached a photo of the test cable you can use.

Also, you can check your subs to see if they still work by simply touching a 1.5V battery to the speaker leads. If they are still in functioning order they will move when you touch the speaker wires to the battery.

If the amp turns on, the RCAs are probably the culprit. Check them from the head unit all the way to the amp.

Also, test the sub to ensure it will fire. Take a small battery (i.e. AA) and place the + speaker wire on top of the + side of the battery, and the - speaker wire on the - end of the battery. The sub should respond with slight movement.

If the RCAs and the sub itself check out, it may be a problem with the amp. Ensure that the amp's settings are correct. Perhaps the switch that controls high-pass and/or low-pass filters was moved when you took the turn. Make sure it is set to low-pass, and the gain knob is turned beyond zero.

Speaker leads are what? the magnet? haha. i'm a n00b.
