This enclosure holds 0.460 cu ft net per driver. In it the Kicker CompRT10 (CWRT102) runs a system Qtc of 0.94 with half power at 44.9 Hz, and the cone reaches its 13.35 mm travel limit at 450 W per driver, above the driver’s 400 W thermal rating, so heat stops you before travel does. A 25 Hz subsonic filter adds little here: 466 W per driver against 450 W, 3 percent. The box already resonates at 55 Hz, so its own rolloff has removed most of what the filter would have stopped.

00Sizing the amplifier

Every wattage on this panel is per driver. This cabinet holds three, so the amplifier feeds all three at once.

Per driver 280–400 W RMS  ×  3 drivers  =  full set 840–1,200 W RMS at 3 ohms
Look for a mono amplifier rated 840–1,200 W RMS at 3 ohms, the load the set wires to most easily. The top is the driver’s 400 W thermal rating; with the 25 Hz subsonic set the cone still has travel to spare there, reaching Xmax only at 466 W. Below the bottom of the range it will play, just with less headroom; above the top you are buying power the drivers cannot use.

01Is it a sealed driver?

Efficiency bandwidth product places the motor before anything else is decided.

EBP = Fs ÷ Qes = 56.8
SEALED 0–50 TRANSITION 50–100 PORTED 100–150 0 50 100 150 Dual 2 Ohm 56.8
Dual 2 Ohm · EBP 56.8
At 56.8 the CompRT10 (CWRT102) sits in the transition band, not the sealed band. That is not a mismatch: a transition motor works in either alignment, and sealed buys a smaller box and a gentler roll-off at the cost of some low-end output. Stage 02 shows what this airspace actually does with it.

02What the box does to it

0.460 cu ft against a 35.4 L Vas.

α = Vas ÷ Vb = 2.71  ·  Fc = Fs√(α+1) = 55 Hz  ·  Qtc = 0.94

Dual 2 Ohm · Qtc 0.94, Fc 55 Hz, F3 44.9 Hz
The box lifts resonance from 28.7 Hz free-air to 55 Hz and half power lands at 44.9 Hz, anechoic, before any cabin gain. Figures are Kicker’s published parameters; Qes and Qms reproduce the printed Qts. This cabinet holds three drivers in three separate sealed chambers of 0.460 cubic feet each, the volume plotted here.

03The watts that reach Xmax (in this enclosure)

Travel scales with the square root of power, so there is one wattage that puts the cone exactly on 13.35 mm, and in this alignment a subsonic filter barely moves it.

PXmax = 450 W per driver unfiltered  →  466 W per driver with a 25 Hz subsonic
20 30 50 70 100 150 200 0 4 8 12 16 FREQUENCY · Hz CONE TRAVEL · mm PAST LINEAR TRAVEL · Xmax 13.35 mm 450 W reaches Xmax here
Dual 2 Ohm · 450 W, no filterDual 2 Ohm · 466 W with subsonic at 25 Hz, 24 dB/octXmax 13.35 mm one-way
Every trace touches the limit and no further, because each is drawn at the exact power that puts that coil on 13.35 mm. Unfiltered that is 450 W per driver, reached first at 36 Hz. It sits above the 400 W the driver can take thermally, so the voice coil gives up before the suspension does. The dashed traces are the same driver behind a subsonic filter at 25 Hz, 24 dB/oct, and they sit almost on top of the solid ones: 466 W per driver against 450 W. At 55 Hz the filter sits well below resonance, where the sealed alignment has already rolled the cone off at 12 dB/oct, so there is little wasted travel left for it to recover. Set it anyway to keep road rumble out of the cone, but do not size the amplifier around it.

From the shop floor

Installer's take

Start with the size. The maker's minimum sealed size is 0.37 per driver, but the 3.44 in deep motor sets the top of the wedge at 4.49 in, and the smallest box that clears it holds 0.460 per driver. 0.460 cubic feet per driver puts the CompRT10 at Qtc 0.938, resonance 55.3 Hz, half power 44.9 Hz anechoic: a firm lift near resonance, 0.9 dB above flat.

Measure the base depth, not the top. This cabinet is 10.68 in deep where it meets the floor, 4.49 at the top, 40 wide and 17 tall. In an SUV the 40 has to clear between the rear wheel wells at floor height, the base depth is measured from the seat back with the seat upright and latched, and the 17 has to clear the cargo cover.

All three terminal cups are on the rear panel, and the rear panel is the face that goes against the seat back. Wire all three before the box goes in, with enough slack to slide it into place; once the raked face is against the seat you cannot reach them.

Impedance. CompRT10 (CWRT102): wire for 3 ohms (coils in parallel, the three in series), the load most monoblocks are built to deliver full power into; 1.33 ohms is the other clean option (coils in series, the three cups in parallel). Work the load out before you buy the amplifier, not after.

Power. Size the amplifier for the set, not one driver: 280 to 400 W RMS per driver is 840 to 1,200 W RMS across all 3 at 3 ohms.

Kicker's Qes and Qms reproduce the printed Qts within 3 percent, so the alignment rests on a self-consistent set.

Polyfill is in as a wall lining in every chamber. Do not add more: it makes the box act larger and walks Qtc off 0.94.

Before you order

Questions

Does this fit the Kicker CompRT10, and its coil versions?

Yes. Each opening is cut to 9.125 in for the 10.6875 in frame, and the 3.44 in deep motor clears the raked rear panel with 0.75 in to spare. Coil versions of the Kicker CompRT10 share the frame, cutout and mounting depth, so any of them drops in. The alignment on this page is computed on the CompRT10 (CWRT102) parameters.

Run three matched drivers, same model and same coil, so every chamber sees the alignment on this page.

Why 0.460 cubic feet per driver, and what alignment does it target?

On Kicker's published Fs 28.7 Hz, Qts 0.486 and Vas 35.4 liters, 0.460 cubic feet per driver gives Qtc 0.938, system resonance 55.3 Hz and half power 44.9 Hz.

The maker's minimum sealed size is 0.37 cubic feet per driver, but the 3.44 in deep motor sets the shallowest the wedge can be, so it comes down only to 0.460: a firm lift near resonance, 0.9 dB above flat.

What amplifier power should I run, and how should I wire it?

Kicker rates the CompRT10 at 400 watts RMS per driver. Recommended amplifier: 280 to 400 W RMS per driver, 840 to 1,200 W RMS for the full set of 3.

Each CompRT10 (CWRT102) has two 2 ohm voice coils, 4 ohms in series or 1 ohm in parallel. With each driver's coils in series and the three cups in parallel, the three present 1.33 ohms to a mono amplifier. With each driver's coils in parallel and the three in series, they present 3 ohms. Three drivers do not reach the round loads a pair does, so check the result against your amplifier's minimum stable impedance before powering up.

Will it fit my SUV?

It is 40 inches wide, 17 tall and 10.68 deep at the base, tapering to 4.49 at the top. Measure between the rear wheel wells, the floor depth with the seat upright, and the height under your cargo cover.

The raked face goes against the seat back and the woofers fire toward the liftgate.

Why are all three terminal cups on the back?

Each driver has its own sealed chamber, and the center chamber has no side wall to take a cup. Putting all three on the rear panel gives a matching set, one cup per chamber.

Wire them at the amplifier end; there is no cross-chamber wiring inside the cabinet.

What is the expected low-frequency extension?

Anechoic F3 is 44.9 Hz per driver with system resonance at 55.3 Hz.

Those figures exclude cabin gain. An SUV cabin adds real output below about 50 Hz, so in-vehicle response runs deeper than the numbers above.

Do I need to add polyfill or damping?

No. Polyfill is already installed as a light wall lining in every chamber, and the quantity is chosen so it does not change the acoustic volume.

Do not add more. Packing a sealed box makes it behave as though it were larger, which moves the alignment away from 0.460 cubic feet per driver.

Are the drivers included?

No. This is an enclosure only. You receive the cabinet finished in plush black carpet with the gloss black acrylic baffle insert, three pre-wired terminal cups on the rear panel, the polyfill lining in place, threaded inserts and stainless machine screws.

Bring three matched Kicker CompRT10 drivers. The cabinet is cut direct fit to them, not a general purpose 10 inch box.
