    subs are usally rated for there max capacity I wouildnt go anything above that unless you really like that burnt electrical smell in your cab.

    The speakers are rated independantly - each can only handle 600 rms - do not add them together.

    The RMS figure is really meaningless - its an often exagerrated figure. Depending on the brand of sub/speaker I would only get an amp that can deliver no more than 600 watt to each sub continous power.

    And remember more watts does not always mean louder.

    I would go off the cubic feet of the box per chamber or if it just single. And look what is recommeneded for the sub. Like i know my jl 12 w3 is 1 cub so that is what i have. So if you get a sub with a reccommendation for a box that it is bigger then the cubic of the box then it will not sound good.


    To make it sound good it is all in the box and 3/4 of the rated rms to the amp.

    I'd get the JL audio thin. Its got great power, I heard it at car shop. I have 2 10" W0's and there great. I dont think i'd get anything besides JL.

    here is the statistics on the sub im looking at

    Free Air Resonance (Fs): 27.52 HzElectrical “Q” (Qes): 0.511Mechanical “Q” (Qms): 11.230Total Speaker “Q” (Qts): 0.489Equivalent Compliance (Vas): 2.10 cu. ft. / 59.47 litersOne-Way, Linear Excursion (Xmax)*: 0.383 in. / 9.7 mmReference Efficiency (no): 0.233%Efficiency (1W/1m)**: 85.87 dB SPLEffective Piston Area (Sd): 98.256 sq. in. / 0.0634 sq. m.DC Resistance (Re): 2.793 ohmNominal Impedance (Znom): 3 ohmThermal Power Handling (Pt): 600WDriver Displacement: 0.052 cu. ft. / 1.47 litersNet Weight: 18.6 lbs. / 8.4 kg

    the the box is .6 cu.ft for each sub and it holds two will this work
