Hello all, From new york here. Everyone told me fi was better then memphis but i have some questions to be answered. i guess i could ask them here seeming this is my first post... right? Okay, So i have a 2001 jetta, i dont know how big my trunk is and i suck at math. I was orignally going to get 2 12's btl but everyone told me that i would neeed to upgrade my alternator and the big 3. is this true? so my other option was to go with the 2 12's BL, but i dont know if i would still need to upgrade anything electrical. but either way, i would perfer to get the btl but dont have enough money to get a new alternator and the big 3 okay, now either way if i were to go with the btl or bl, what would i want to configure the woofers too? like this list thing Ohm: P Chamfer: Cooling: Flatwind: Daily or SPL: Extreme Lead: Universal: Dustcap: i would be using this daily, so i asuume i would do daily, but everything else.... wtf does it mean? and waht kind of amp would i need to power this and where would i get all the wiring? Thank You P.S How do 2 12" BL sound? do they get loud and hit low?
