Hey all. Name is Rex and I'm new around here but not new to forums. I am starting a stereo upgrade in my DD Mk5 Jetta and found this site and there seems to be a lot of knowledge so I figured I would sign up in case I have any questions. Right now I am running a 12w3 in a box that is to small for it so so I will be building an appropriate box as soon as it warms up. It's being "pushed" by a JL 250/1 also to small for the sub that will be getting upgraded to a 5 channel in the 900 watt range to also run some 3 ways up front. The w3 was just purchased to replace the blown w0 that was with the box and amp hence the reason for the mismatched specs. Secondly I just messed around and bought a 13w7 last night that I may play with for a very short time but will likely end up selling because its just to much for my needs! Anyway glad to be here and hopefully I can find a way to give back a little as well.
