JVC KS-AX4700 doesnt work

posted by jlong on Aug 16, 2006


My JVC KS-AX4700 no longer works. When it is hooked up, very little power comes out (meaning subs barely hit, but some noise is heard).

I have it apart, and I would love to fix it myself. Can someone help me out as to what the common parts that go are? What should I look for? Is it OK to dissassemble the board from the casing? Is it possible that there is still electricity stored in it (it was "undone" more than a month ago)?

Any help would be appreciated. I am good at technical things, although I have very little electronics experience.

The posted article only diagnoses user problems. I am experienced with car audio instalations. I need an electricians help diagnosing what to fix inside the amp.

Get a new amp. JVC is pure trash.

You're looking for a technician, not an electrician.

Check your gains and head unit settings.

"I am good at technical things, although I have very little electronics experience."

Then you can't fix it.
