as of right now im pushing 2 12 inch p3s with a downward fireing sealed box and was thinking about ubgrading to the JL w7s with a vented box and maybe a new amp, im rocking a 900 watt sony xplod monoblock
trunk space is not a problem, i have a ford excursion and i was thinking i would like just clear sound maybe a little louder than what i currently have
i dont think im gonna put in anything else but the subs and amp and whatnot
Don't get caught up in wattage. RMS is the rated power, and it is what everyone that knows anything about car audio goes by.
Yes your p3's advertise 1000 watts, but that is really 500 RMS a sub, so 1000 RMS total.
The Fi Bl does is a suggested 1000 RMS sub, but can do more. 1600 RMS is a common number to run them at, and if you get power options like flatwind coil, there is no way your blowing them.
Once you get in the 2000+ RMS range you have to start thinking about upgrading your battery and alternator, so keep that in mind.
Also remember that a good system is nothing without a good head unit. Pioneer, Alpine, and Clarion.
Not many people suggest JL because there's better out there for the money. They are a good sub, but the brands I recommended will get louder and sound better doing it for the same price, or even less.
