Sounds Good Stereo - Custom Package

I paid nearly 5k for the entire system, when they first arrived I got it installed by an audio shop, the subs worked for about 2-3 months before completely stopped working, sounds good stereo replaced the subs, now I’ve had them for about 5 months and the same thing happened. They have completely stopped working, 2 of the 4 subs lost the center cap. I feel like the company uses cheaply made subs. Although they are suppose to be on the high quality range (focal flex evos) they are completely garbage. I would recommend just purchasing the sub box and using your own brand of subs.
