Our take on the Pioneer A-Series TS-A120D4 12" Subwoofer 1500W Max

Questions and answers

What amplifier power does the Pioneer TS-A120D4 need?
It is rated at 500W RMS, so an amplifier that delivers around 500W RMS at the impedance you wire it to (2 or 8 ohms) is ideal. With 77 dB sensitivity, more power helps it reach higher output.

Yes, the dual 4-ohm voice coils can be wired in parallel for a 2-ohm load or in series for an 8-ohm load. Make sure your amplifier is stable at the chosen impedance.
What size enclosure does it need?
Pioneer recommends a sealed or ported enclosure, but specific dimensions depend on your vehicle and desired bass response. Check the manual for recommended box volumes.
Is this subwoofer suitable for a truck?
Yes, it can be used in trucks if there is enough mounting depth (5-3/4 inches) and space for an enclosure. It is not shallow mount, so check available space.
What is included in the box?
The subwoofer comes with a trim ring and an adhesive-backed foam gasket. Mounting screws are not mentioned, so you may need to supply your own.
