Our take on the Alpine SBR-S8-4 8" Powered Subwoofer Enclosure

The Alpine SBR-S8-4 is a compact 8-inch subwoofer in a factory-tuned ported enclosure, built to add low bass to a car or truck without eating much cargo space. It uses a dual voice coil driver rated at 350 watts RMS, so it needs an external amplifier rather than a built-in one. It suits drivers who want a small, easy-to-place bass box and already own an amp. Against bigger ported boxes it gives up deep output, but it fits under seats and in tight trunks where 10- and 12-inch enclosures will not.

Questions and answers

Does the Alpine SBR-S8-4 have a built-in amplifier?
No. It is a passive enclosure, so you need a separate mono or bridged amplifier rated near its 350 watts RMS.
What amplifier should I pair with it?
A mono amp that makes around 300 to 400 watts RMS at the sub's impedance works well. Match the amp to how you wire the dual voice coils.
Can I wire the dual voice coils for 2 or 8 ohms?
The two 4-ohm coils wire in parallel for 2 ohms or in series for 8 ohms. Check that your amplifier is stable at the load you choose.
Will it fit under a truck or hatchback seat?
Its 8-inch driver and compact box make it one of the easier enclosures to tuck into shallow spaces. Measure your space before buying.
Is it worth it over a 10-inch sub?
If space is tight, yes. A 10-inch ported box will play louder and deeper but takes noticeably more room.
What is in the box?
The loaded ported enclosure with the 8-inch dual voice coil subwoofer installed. Amplifier and wiring are sold separately.
