Hey guys I am back for some of yrou expertise. I hooked up my two 10" type r's to my bx1205 hifonics brutus amp. And I was smelling the voice coils on the first day so I put the gains down. Used it for another few days and now one of the subs got burnt out. I dont understnad what I did wrong. Bass eq was less then half. Crossoever was around 90hz.And subsonic was around 20hz. Can you guys help me to know where I went wrong? If you are unsure where to set the gain its always better to have it lower correct? Please help me guys. I dont want to blow another one.Thanks

How did you set the gain?

Gains, gains, gains. learn how to either set them correctly or take it someplace that knows how. a few bucks to have a store do it for you is better than having to buy new woofers.

I agree with you all. It is better
but I have never had this problem and I have had over ten different setups over the years. Always done my self. This amp has input gain of 9v -0.2v. Does that have to do with anything? I only had the gain about 1/3rd the way. But then again it may have been a defective sub as I bought that one used. Cause I just removed the working one which I bought new. And it has no burnt smell what so ever. But the other one that blew smells like a grill.

Also when setting gains withoout a dmm. I know you set everything to 0 but is this including the crossover? Or do you set the crossover point and then turn up the gain till you hear a little distortion then back down a notch.

One of a couple of issues. (1) you played the system too long and too loud and did not allow the subs to cool. (2) improperly set gain sent a clipped signal into the sub and again the sub could not cool and melted. (3) improperly wired and again, too much power or clipped signal and the thermal barrier was broken. End result the same in all cases, blown sub. ------------- Top Secret, I can tell you but then my wife will kill me.

Used sub smelled burnt and blew up, new sub didn't smell and runs fine. I think you answered your own question.

I guess that Brutus just spanked that woofer too hard.I used to use our Colossus(600 W @ 4ohm per ch,1800 @ 4 ohm bridged) to show some customers of other brands of speakers what REAL power was.The sound quality was outstanding on a lot of woofers but the real power handling of some brands became apparent when we stood on it.
