[QUOTE="bbeljefe, post: 8295935, member: 655960"] Your head unit doesn't make 50 watts per channel, it makes 15-18 watts per channel and head unit amplifiers normally begin to distort at about half volume so changing the speakers will not correct that problem. Adding an outboard amplifier will. As for the subwoofer amplifier, you're not going to get much out of that setup with that amp. It won't do its rated power so at best you're probably getting 80 watts to the sub. It might help to change to 4 gauge wire but since I don't know the brand of power wire you currently have, it's hard to say. I say that because there are a lot of 8 gauge amp kits out there that don't actually have 8 gauge power wire with them. It's usually undersized and can be as small as 12 gauge wire with a lof of thick insulation around it to make it look like 8 gauge. Also, seat bolts are usually not good ground points. The factory uses thread locking compound on them and that makes the electrical connection poor. It would be a good idea to go to a strut tower or to the frame, if your care isn't a unibody. [/QUOTE]
