Tryin to put 2gether a system..I have a 2000 buick lesabre limited(lots of trunk space lol)?

It depends on what size door speakers u have. I'm putting 6 twelve inch kickers in my 03 Buick century with 3 1000 watt amps but i like alto of b. if you want regulate b put in like 2 12s or 4 10s. you will get an aw some sound system and probably will still have lots of money left over if you go with kicker. Also for good voice add tweeters and buy a couple of 6x9s and put them in boxes/ If there is any money leftover i would put in a custom box that looks nice in there
