viperd911 Posted May 11, 2009 Report Share Posted May 11, 2009 i have two 12'' p3 shallows 2 ohm off of a alpine mrp 850 at 800rms at 2 ohms tuned to 75hzbut with the 1.9 cubic foot box they are in now the subs will not hit low. They sound like 8 inch subs but get real loud on the songs like a milli by lil wayne. But my sister has the same sub p3 shallow 12'' but a 4 ohm with a p300.1 tune to 80 hz with less cubic feet volume in a suv with .8 cubic feet and hers is almost as loud as mine. I was thinking of build a 3.0 cubic foot box sealed and i was wondering will this let my subs hit lower and louder ive talked to car audio shops and they do not know what to do either so if you can recomend any thing to me well still keeping the box sealed it would be appriciated.

brsteinbach Posted May 11, 2009 Report Share Posted May 11, 2009 (edited) Why did you tune them so high? Oh and BTW to get lower you would need to build a new box that is bigger and tuned way way lower around 35 or lower to around 30 if you really want the lows Edited May 11, 2009 by brsteinbach Quote 2 Infinity Reference 1252w 12s 4.2 cubic foot box tuned to 28hz Sub amp: 1 Profile AP1200 Speaker amp: 1 Sony Xplod XM-504z Kenwood eXcelon KDC-X492 4 and 8 Gauge Knu Big III In 1/0 All in my 90 Accord Diamonds are forever, but 9's end that shit fast....

RamenNoodles Posted May 11, 2009 Report Share Posted May 11, 2009 anything will sound like shit at that high of a tuning frequency. Tune it to 35hz. Quote Diablo Audio Technologies Fi Car Audio Ascendant Audio Link to comment Share on other sites More sharing options...
cracker Posted May 11, 2009 Report Share Posted May 11, 2009 Why did you tune them so high? x2 but what kind of car/truck are they in? not too sure about the shallow subs but is that enough airspace for 12s? like i said i dont know about them shallow subs but alot of 12s seem to be around 1.5 on up for 12s and tuned alot lower. IMO a dif enclosure would be good for what your needin.

Mikesmith0890 Posted May 11, 2009 Report Share Posted May 11, 2009 are you talking about the tuning on the box is at 75hz or is the setting on the LP filter on the amp at 75hz?
