Hi, I have a 01 Sentra and I'm planning a system with the following:
3 Sundown U series 10' 2 ohm 1500 RMS per requires 1.0 cube ported
Ported box 32hz 1.2 cube net per speaker
Or 2 Sundown X-10 V.2 D2 10" 1500W RMS Dual 2-Ohm requires 1.5 cube ported
Ported box 32hz 2.0 cube net per speaker
1 Taramps 8k
4 Fosgate 6.75 3 ways 60 RMS per
1 Taramps 440/4 channel, 69 watts RMS channel
4 Bzrk audio 1"Tweeters RS-T150 75 rms each
1 Taramps 400/4 channel, 60 watts RMS per channel
1 Clarion EQS 755 7 band 1/2 din equalizer
Undecided on head unit
For power I'm planning to use:
The largest battery I can fit in the battery well under the hood
270 amp custom alternator
1 Limitless Lithium 12k
Not sure what's a good brand of isolator to use
Battery compartment is 11" x 7" x 8.25" height.
Trunk is 40" x 28" x 20" height
Trunk opening will fit a box 33" width and 17.25" height.
Using an online box size calculator I Arrived at the following dimensions:
Box External Dimensions
Width × Height × Depth32.00" × 15.00" × 21.86"
Material Thickness0.75"
Net Internal Volume3.60 ft3 (4 if i go with the x series due to speaker displacement)
Tuning Frequency32 Hz
Port Area42.00 inch2
Port Inlet Width × Height3.11" × 13.50"
Port Length22.79"
So this is what I've figured out so far. The 3 U series subs can be wired to 1.33 ohms at 1.2 cube per sub, but the 2 x series can be wired to 1 ohm at 2.0 cube per sub.
What I'm not sure of is if that's enough cube for the speakers. It meets manufacturer recommendations, even a little over. But I see these guys on YouTube with these huge boxes that are way oversized for the speakers doing crazy loud stuff with the setup.
Also, given that my trunk can fit 33 X 17.25 X 26 inches (accounting for excursion) for a sub box how much can I safely increase the box size to do that it still fits? Can anyone help to point me in the right direction and opinions on which speaker setup will be optimal?
Thank you,
