Yea they are but I think i finally want to step up to the bigger subs been using tens and 12's for like the past 4 or 5 years.. idk though i just wanna be able to hit at least 145dbs or 150 if possible not for a daily system but i wanna be able to produce those types of numbers and its a lil more difficult to do that with a couple tens instead of a 15 or so... So if anyone has ideas on a good system let me know..
And if anybody could tell me how much i would need to be able to do a whole upgrade including Sub,amp,wires,etc...
