ZachG Posted August 2, 2012 Report Share Posted August 2, 2012 Ok so I'm revisting this subject cause I got the money to do it even though I didn't sell all my amps and subs yet. I want 2 15s They have to be 500rms or lower each. I ruled out p1s cause the kicker comps are better but need bigger boxes... Any suggestions would be great. Small box requirment subs is what I'm looking for Quote 1998 Pontiac grand prix gtp supercharged2 12" Obsidain Audio V.1 on a 2011 zx1500.1 at 2 ohms. 20ft of Knuconceptz CCA 0 Guage. 2nd Battery is a Shurken BT-120. Box is 3.5cu tuned at 31.8hz sealed off from the trunk. 14sqft of Dynamat on the Rear deck top & bottom. Soon to be more for doors/roof. Gets low & loud Did a 140.5 Sealed at Battle of the boom in June 2013 dropping to 12.7v (need a alt mines going bad) Link to comment Share on other sites More sharing options...
ZachG Posted August 2, 2012 Author Report Share Posted August 2, 2012 The amp will be 1000rms or less pending on the subs Quote 1998 Pontiac grand prix gtp supercharged2 12" Obsidain Audio V.1 on a 2011 zx1500.1 at 2 ohms. 20ft of Knuconceptz CCA 0 Guage. 2nd Battery is a Shurken BT-120.

john253a Posted August 2, 2012 Report Share Posted August 2, 2012 (edited) Why do they have to be 500 or less, That's pretty dumb, as you'll rule out some quality equipment, Noone has ever blown a sub due to under powering, What's the budged Amp mdl Size restriction/space avaible (this is the most important) Car Sub/port config if ported or sealed And what do you want to achive Edited August 2, 2012 by john253a Quote Link to comment Share on other sites More sharing options...

Hit low. Don't want over 1krms cause don't want to do a big batt in my 98 gtp 4 Dr. Trunk setup, max dimensions are 15.5h 36w 31d I want a efficient setup. 2 500w 15s would be louder than 1 1000w 15 Quote 1998 Pontiac grand prix gtp supercharged2 12" Obsidain Audio V.1 on a 2011 zx1500.1 at 2 ohms. 20ft of Knuconceptz CCA 0 Guage. 2nd Battery is a Shurken BT-120.

john253a Posted August 2, 2012 Report Share Posted August 2, 2012 The question should be 2x 15 that work well on 500 each There are a heap of stats that prove that a 2k sub on 500 is not alot louder in the same environment, You'll find power shows a bigger % incress in db down low but up high, I can't run any numbers yet But in 1k there are a lot of options Quote Link to comment Share on other sites More sharing options...
john253a Posted August 2, 2012 Report Share Posted August 2, 2012 With out running the numbers I already see some problem 36w -(2x15.5") and 1.5"wall "32.5 Only leaves 2.75" width for port And 38sq" is not enough port for 2x 15's Yes cone is king on low power but I feel you'll get a better outcome and output form 2x 12" Quote Link to comment Share on other sites More sharing options...
bkolfo4 Posted August 2, 2012 Report Share Posted August 2, 2012 2 500w 15s would be louder than 1 1000w 15 Comparing the exact same model sub in the same alignment, this statement is more than likely true. Comparing two different subs or alignments, it will not always be true. AA Arsenals would be a nice sub for ~500 watts.

bkolfo4 Posted August 2, 2012 Report Share Posted August 2, 2012 That's a lot of idk's Why down grade the amp. If you have the remote gain, just keep your fingers from cranking it up all the time. Extra power is a great thing, and it will be there if you want to use it for short periods of time.
