[Ok Whats Better For Daily Ust?]

ok for my upgrade i was thinking 4 to 6 15's but i always am listening to my stuff, longest is 1.30hours. so what would be best and loud?

well this question is kinda hard to answer... chances are that if you have 4-6 15's its going to be loud no mater what... unless your box sux... i wouldnt be worying about which brand... id be worying if your electrical system can provide enough power for that long of a period of time...

[What Meter Is This]

which ac meter is that? our local shop uses the spl190 and the mic looks totaly different than that...

[Camaro Box]

if your just going to go sealed i would just get the prefab that is made for the car.... i had a buddy that had a 90's camaro with the prefab and 2 12" diamond audio cm3's and that thing slammed hard!.... but if your going to mix it up and go with a vented design id say build it yourslef....
