I'm not gonna lie that's all the amp is secured to. It seems to be working so far. As far as the sound goes, I think it works really well. It hits pretty hard. I know it's not the best, but for what I use it for, it's perfect.freshness said:Looks good man. What do yiou have your amp bolted to? It looks like it's just screwed into the carpet. BTW, I have the same subs/box but in a 10". How do you like the sound? Is that the new head unit?
