IcePower 500a failure

Hey guys!

I recently built a 4 channel amp using; 2 x IcePower 200ASC + 200AC modules (Mids/highs) and 2 x Icepower 500asp + 500a (lows) all running off of a Minidsp 2x4..

Im driving this(500a) board directly from the 500ASP module and I have 2 x 100v 3300 caps between the modules.. (icepower notes adding capacitance between modules for extra power duration).. I'm running these modules at ~2.6 ohms (3 - 8ohm woofer in parallel) and the data sheet states min. of 2 ohms.. Also.. both are mounted on heatsinks AND fan cooled!

So.. the issue...

Few weeks ago.. The 500a module failed and blew off a ceramic cap.. Im wonder what would have caused this?? Bad cap?? Bad luck?? 😏
I'm assuming this is something of a rare event and isnt something i did wrong.. (which is what im hoping!! lol )

When the amp module failed i was NOT pulling any power.. was just watching TV so probably at best.. a few milliwatts of power being pulled from the modules..

THANKFULLY the main module (500asp) was not harmed at all and I have since received a replacement 500a under warranty!

That thought didn't cross my mind.. but i purchased them from Parts Express!

I did receive my new one (has a manufacturing date of last year!) and will be installing that.. Getting another free one from a warranty replacement.. so I guess i'll have another back up! 😏
