I'm just a little unsure. I had an (5000 boss sub package)nx12d 2500 watts boss sub and one side blew not long after installing the two together, (got the subs before the amp)the sub worked completely fine with all my other amps. went back and bought (4600 watt boss phantom subs)one sub blew same side I believe. That blew in the first month so working on warranty, went into protection mode a couple times and had to replace fuses 4 or 5 times. I used some 100amp and 80amp fuses from walmart. I just got the two leftover subsmixed matched in a altrend box. Had it in a day so haven't gotten to turn it up yet but sounds better now but had it in a day so I will test it out. I ordered a 5500 watt amp hoping for better luck with all the extra power. I got a 200 anl fuse a 150amp fuse and a boss power capacitor that i want to hook up but waiting to see what happens with the warranties ordered another phantom 12 while I go through the process will let you know how the customer service is. First time working with them and they seemed very helpful thus far...Read full review
