[will these subs be louder than the ones i have????]

I have 2 12 alpine type x's (was an alpine freak)

one blew and now i'm getting 2 12 fi bl's fully loaded.

will they be louder or around the same?

[my lights are flickering]

i have a stinger one bought from my local audio shop. this is gonna be funny but i bought it for 800 and been having a lot of trouble with them so i think im going to buy one from dc and get my money back because i think this shop likes to screw a lot of people over.

also i noticed this when my alternator makes funny noises like when its turning my lights flicker on sequence with it so im sure it has to be the alternator.

opinions on what i am dealing with and what i should do?

Sorry for thread jacking just thought we had the same problem so i decided to not just make a new thread.

[my lights are flickering]

I have the same problem. all my lights flicker and my voltage meter goes up and down but never a difference greater than .5 volts and alternator does make funny noises.when i accelerate the meter goes back to normal. but when i put a load on the alternator the flickering goes away... do i have the same problem. oh and yea the meter problem goes away when a load is put on as well.
