I need some advice on my set up this is my first real time playing with car audio an need help.. I got two Alpine type r's dual 4ohm the newer models 600 rms in a 30x14x14 sealed box wired down to a 1ohm load an being pushed by a Boss Phantom 5000 an a bx-10 soundstream epicenter but I only use it when I am bumping spanish music(corridos, Banda etc)other then that it's not connected because it doesn't sound good with My rap music. I am using 4awg power an ground wire with a 100 amp ANL fuse an fuse block. I have a stock battery an stock altenator. My questions are are alpine type r's really good subwoofers? An what about the boss amp? Cus I really don't think it's pushing a real 5000 rms like it says. I bought the amp thinking it was a good deal for $150 but now I don't think it's even close to pushing my Lil type r's To their full potential. I have the gain on the amp more than 3/4 up an it doesn't seem that loud. Some of my friends say if I get a ported box they will be way louder an others say its my amp. Also sometimes when I'm playing it loud after a while everything including my kenwood deck shuts off?. So what do you guys think I should do? Get a better amp? Upgrade my electrical? Any help would be highly appreciated.
