[QUOTE="focusedRS, post: 8728247, member: 681812"] Hey folks, I was hoping to get a second opinion about my setup that I had installed recently by a shop. My initial setup consisted of an Alpine MRV-500 Mono amp paired with a shallow mount Rockford Fosgate R2SD4-12 sub in a 2016 Ford Focus RS. I paid a pretty penny for a custom box to fit in the false floor by where the stock sub goes. When the car was returned to me, it sounded good and the bass was pretty powerful that I had to turn the bass down on the stock head unit and turned off the bass booster EQ on my iPhone as soon as I got the car back to me. About 15 minutes into my drive home, the sub cuts out in the middle of a song. Mind you, I was not blasting the stereo, it was only on Volume 20. When it kicked back on, the sub sounded horrible (blown). I took it back to the shop and explained the situation and the guy who installed everything told me my sub is blown and he has never seen a sub blow like that before? He blamed the manufacturer and advised to get another sub so they can swap it out...... I then purchase a Rockford Fosgate P3SD4-12 which has a higher rated RMS just to be on the safe side so this doesn't happen again. I get it installed by the same shop (Christmas Eve) and proceed to drive to my parent's house for Christmas which is 2 hours away. About an hour into the drive, the sub dies and now sounds blown. This is now 2 brand new subwoofers blown in the span of two weeks. I call the shop to explain the situation and they assure me the install was done correctly and it must have been a faulty subwoofer and implied I should have purchased the subwoofers from them........... I paid a lot of money for this setup to be done by professionals because I am not too familiar with this stuff but out of the 4 cars and 3 different sound systems I have owned previously this sort of situation has never happened to me. I have never used this shop before but it has been highly recommended by the Focus groups here in Central FL so I am swimming upstream if I go and blast them. I'll post pics of the settings to see if maybe someone can determine what might be the issue as I really do NOT want to buy an additional sub/amp and have this happen again where I'm literally throwing money in the wind. Small side note, my car spent a full business day at this shop. When the car was returned to me I noticed my dashcam was unplugged. When asked why they explained it was company policy.
