Default Help Fire - Need New Sub Amp

My buddy said this sub amp almost caught on fire! The Amp is only about a year old with a 8ohm load/hookup.

The speaker(s) & amp are ruined, but he wants to get it working again.

Q. What's a good sub amp that doesn't cost a fortune? And one that he won't have to worry about the house burning down.

Nevber underestimate the importanse of FUSES.

Hypex-modules are generally good AND reasonably priced.

And buildt with the recommended fuses and other safety-recommandations You should be safe.

Even though the amp is fried, you should still be able to reuse the power supply and active filter, and just replace the amp board with something else, this saves some money you otherwise would need to spend on psu parts.

This assumes the original amp havent been thrown out already though.

For a sub, if you want efficient and cool, get some kind of Class D based amplifier module.

Some good ideas, a fuse would have saved the sub woofer speakers.
(There are two in the box hooked in series)

I've bought 4 of the $100 plate amps over the years; only one is still going.

We finished this together last Nov, so it didn't last long (13 months)

It could be:

Bad Design
Bad Manufacturing
OR
Severe Overdriving the amp.

They short cut the design and/or use cheap parts.

Can't push the woofers in this box - soft suspension/floppy cone(s)
