best way to fry a stereo

What is the best way to inconspicuously fry a stereo for warranty purposes? Cannot cause physical damage and must fry stereo beyond basic repair. The stereo is a Alpine cda-9886 and will be traded out for the alpine cda-117 pending that the destruction is adequate.

Alpine? Accelerated life testing perhaps? Others can fry with sustained full/high output with low input voltage (say 8-11V). Some even with consistent high output. But that and other failure modes for good units requires extreme environments such as high temperatures, incorrect speaker wiring, spills, vibration, over voltage or high AC content etc. And such situations usually void the warranty etc. Good units feature input, output & temperature protection. The warranty is to cover for manufacturing defects which should be the only way a quality product fails. But someone may know a trick.....

It's a in store warranty. Would cover things such as screen not illuminating, rcas not working, anything under the sun that's not physical damage. I just really need a stereo that charges my iPhone, it's not that I don't like it. My suggestions so far have been power it into a wall socket, which sounds dangerous. And also grounding the remote wire to the chassis and letting it slowly overheat itself. That didn't sound like a bad idea but not sure if that would do the properamount of damage or if it would work at all if the stereo was made well like you said. I've also thought about maybe clear nailpolish to the connections for the faceplate? Anyone think one of those suggestions would work at all or one would work better than the other?

Yeah - I covered wall socket with "high AC content lol. Nail polish sounds like sabotage unless it's an accidental spill which is probably obvious, and both are probably removeable. However those damned kids with crayons often get pencils and still graffiti (pun - graphite) everything in site. That's dangerous - apart from disabling petrol cars when they draw under distributor caps (or a line down splug (spark plug) ceramic insulation for those with cap-less cars), they could short out face plate pins. That could blow internal drivers (meaning not the faceplate itself). Most people then wipe of the sometimes burnt carbon track thinking it will fix the problem, but alas the damage is already done. Hence forensically there is little remaining reside - unlike molten copper from fine-wires that do the same damage but may melt or splatter into plastics.    [FYI - I have a Alpine (CDM-9821??) with a blown faceplate vac-fluoro display caused by overvoltage (due to a bad engine-chassis ground). But if it's the faceplate and not the unit, the faceplate might simply be replaced. Another older-model faceplate flouro lights up but shows jumbled segments (different pinouts or coding) so I suspect the unit itself is ok. Besides, with the sun shining direct into it, I can see the proper display.]

Are you sure that it won't end up getting sent out to service because most Alpines  do get sent out.  You may get what you wished for, a burnt up 9886 repaired.Advanced

This is an innapropriate use of this forum.  Inquiries of this sort are frowned upon by administrators.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Cant find anything that would suggest that I am in violation of forum rules. Who doesnt want to get the most out of their extended warranties purchased through retailers?
