Ground and power reversed

So what happens when you wire the power into the ground terminal and the ground wire into the power terminal of an amp or crossover or something? I did this once and blew a fuse, but what happens if the fuse does not blow right away? Is it instant damage to the amps or other electronic pieces??

Thanks.

depends on amp, some amps have a protection against that. For instance my friend accidentally hooked the power and ground wrong on his pg tantrum 1200.1 and it didn't even blow a fuse, another friend did the same thing with his mmats amp and it blew.

I did that with my Ultra Linear. It blew all three fuses. But the amp was fine once I swapped the cables around, and changed the fuses :P

Most amps will (and should) have a big diode across the power terminals. Diodes only let current flow one way. So if the input voltage goes negative it will just act as a short stopping any voltage from going on to the amp's powersupply. A simple safety feature. Another good reason to always use a fuse!

That is exactly why a lot of companies don't warrantee thier stuff unless it is installed by a professional instal shop.
Protects them from having to replace stuff installed by stupid people...

^^Unfortunately for guys like me that do their own installs, and know what they're doing, it leaves me with no option but to avoid those products or buy online since I have no warranty anyway. I Understand the situation from both sides, but in the end it's my money and my car and I don't trust most shops. I'm forced to buy either, other brands that do offer waranty for self installed, or, if I really want that product, to buy it online for a reduced price to lower my risk. I'll knock on wood right now, because in 20 years I've yet to have a warranty return, or, a poor install related problem...knock! knock!
