About the Pioneer TS-A300B
From our tech experts at CEN
A 12 inch subwoofer supplied in its enclosure, handling 500w RMS.
Who it suits
Drivers who want bass without commissioning a custom build, where the box is already matched to the driver.
Our tech experts advise
A subwoofer is only as good as its enclosure and the amplifier behind it. We build enclosures and match amplification at our Beeston workshop. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions
Q: Do I need an amplifier for this subwoofer?
A: Yes, unless it is an active (powered) subwoofer with a built-in amplifier. Passive subwoofers need an external amplifier matched to the RMS power and impedance shown in the Specification tab.
Q: What does RMS power mean?
A: RMS is the continuous power a subwoofer can handle, and it is the number that matters when matching an amplifier. Peak or max figures describe short bursts only. Match your amplifier output to the RMS rating in the Specification tab.
Q: How much power can the Pioneer TS-A300B handle?
A: It is rated at 500W continuous power output, with a maximum power of 1500W. Match your amplifier to the 500W RMS figure.
Q: Does the TS-A300B come in a box?
A: Yes. It is an enclosed subwoofer and box package with a slot-type port, so no separate enclosure is needed.
Q: Which amplifier pairs with the TS-A300B?
A: Pioneer designed the A-Series subwoofers to match its GM-A series of amplifiers. Choose an amplifier matched to the 500W RMS rating.
Q: Can CEN fit the TS-A300B and an amplifier?
A: Yes. CEN offers professional installation from our Nottingham premises, including amplifier wiring. Contact us to discuss your build.
