I have a hole in my Kenwood is it fixable ? - MTX Thunder 6000 T61544A Car Subwoofer

is the buzzing constant frequency

or is it a hum like 50 or 60HZ mains
if its a buzzing like zzzxzxzxzzzzzzzzzz this is a bad connection in the mains and i would turn everything off
and get your supply checked out

Uh oh! Need to go to Kenwood website and have it RMA'd! Failed updates are not always fixable! Needs to be factory reflashed!

It's fixable. Take to a local tv (electronic) repair man. I have them fixed all the time.

I’m happy to help further over the phone at https://www.6ya.com/expert/chris_7f7f91eb941fb23f

In front panel you can find a button inside a hole, press it with pin or needle.

u should have 4 holes in the facia of the cureent radio. use a pair of thin wire type rods in the holes this will release the radio , pull out and diconnect the lead which should be ISO and disconect the aerial and fitt the new unit no problems, if aerial is a black small connector you will need and adaptor, if not great. use the cage that comes with the kenwood or you may not get it out later. if the hole on your model is larger than the kenwood you need a facia plate to sort ths.

Considering 220 and 110 systems have different receptacles, you worked at doing this.
Since it is already inoperable, you may as well remove the housing and inspect the guts. If you see burned traces or boards, don't bother to have it repaired.
If you see a fuse in a clip, you might replace it once, two would be the waste of the second fuse.

Try to purchase a CD disc cleaner, sometimes the "eye" gets partials of dirt on the lens. If that's the problem the cleaner will fix it in no time.

Do you have more than one output? Does the radio have its own amp (it will have cooling fins on the back)? If yes to the first Q, its fixable. Yes 2 the 2nd Q, its trash.

It would be very dangerous to bypass a fuse. If it keeps blowing, bypassing the fuse will only create lots of internal damage and maybe a fire as well. The fuse is blowing for a reason, the amplifier is not going to somehow start working because you bypassed the fuse. You also need to stop trying to turn it on, every time it blows the fuse, it keeps stressing the components inside. You have a shorted power supply, probably water damage as well since the power wire got wet.

I repair car amplifiers for a living, and can tell you with all honesty that bypassing the fuse would be a terrible mistake to make, the amplifier would end up being un-fixable with holes burned right into the board.

Please, just take it in for service or get a new amplifier. That is the only sensible thing to do. The amp will not start working bypassing the fuse, it will only start smoking.

Sounds like you shorted out the main power wire somewhere and killed the amp. Is the amp on the fuse intact or blown? Do you have 12 volts at the amp? check you connections and see if it helps.
