Blew my brand new MA sub again within 2 months.

[I Like Waffle]

Just blew my third 15 from ma audio, 3rd one in less than 6 months. Ive been running them sealed on less than their rated power and they keep blowing //content.invisioncic.com/y282845/emoticons/furious.gif.fc81ca146dbff91fede3ed290dbc4f4c.gif Costs me almost 40 bucks each time i blow one to send it back and get a replacement. If im not clipping and im not overpowering, whats the problem? MA audio seems to be shit. Next time ill be buying RE SEs or Type Arghs to run on my M1000.

You sound surprised. Why would you even buy some junk like that?

yep, with 60hz tone and using the chart that was posted. I was probably only getting about 850wrms out of it as i had to turn it down a little more because my electrical cant handle it as of yet. When i was coming home today i heard a pop and they just shut off, checked the load at the amp and it was 1.2 ohms, so i pull one sub out, its fine, and the box is full of smoke //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif Oddly enough, the sub thats fine is one ive had for almost a year. The one that blew was less than 2 months old. Has no coil rub or anything but the coil reads like .8 i think

I bought them around a year ago originally when i was less educated and on a small budget. I got a good deal on them though, as of now i have about 150$ invested in the pair. Ill probably send this one back and get it replaced, then sell them to someone and let it become their problem. Atleast they have a 2 year warranty.

Also, i have one i run in HT and its completely fine, diff MA sub than these though. I guess ill just put my 4 12"s in for now //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

They are cheaper subs, but they sound good for a budget sub.

I just cooked my 2 MA audio 10s for fun, think coil smoke is bad for me? Around sept ill see about getting some RE se's or type Rs though. Def wont buy anymore MA audio.

do u have a subsonic filter? when i sold ma i would run min of 600rms each in customers car and never had a sub failure.

i was running them sealed, so i figured no need for SS, am i wrong? They werent bottoming out, i guess they just couldnt handle power. When i removed them from the box it was full of smoke and both were really hot.

should have just waited and got the resonant engineering or the alpines. instead of going cheap till u got what u wanted. sumtimes waiting will be better in the end as i found out b4.

i never used the ssf in a sealed box or my last box that was tuned to 28Hz and played lower tones. 146.7@25Hz 140.1@20Hz 4 L7 15s never bottomed out.

You don't need ssf on sealed box.

nope not on a sealed box. were u using bass boost? i have seen 2 xe 15s burp off a 4000d. they are a great entry level sub...
