PowerBass OE8C-T3Y Tesla 8″ Component System | Drop-In Fit

For over 30 years, Safe and Sound has helped UK drivers get more from their in-car audio — and the OE8C-T3Y from PowerBass is the upgrade Tesla owners ask us about most. This 8″ direct-fit OEM replacement component system is designed for the Tesla Model 3, Model Y and Cybertruck — including the latest Highland and Juniper revisions — bringing genuine bottom-end weight and refined detail to your factory sound while keeping the interior and wiring completely standard.

Why choose the OE8C-T3Y?

Tesla cabins are quiet, which makes the factory speakers’ shortcomings easy to hear — especially the front door woofers. The OE8C-T3Y replaces those OEM 8″ drivers with upgraded woofers that deliver an immediate lift in bottom-end response, while the included tweeters refine the top end. PowerBass has tested the whole system to ensure a genuine drop-in design that matches the factory bolt locations and plug styles, so the upgrade goes in cleanly and comes out just as cleanly if you ever need it to.

• Proper low-end at last — upgraded 8″ woofers with treated paper cones add the depth and weight the factory front doors lack.
• Smarter highs included — 1″ silk dome tweeters rotate straight into the door pillar position and plug into the factory harness, with in-line crossovers smoothing the response curve.
• True plug-and-play design — nylon OEM adapters, factory-style connectors and matching bolt patterns mean no holes to drill and no wires to cut.
• Built to be driven — 90W RMS / 180W max power handling, comfortably ahead of the factory units and fully reversible.

Build a complete Tesla sound upgrade

The OE8C-T3Y is the heart of PowerBass’s full Tesla OE Series. Pair it with the OE40CN-T3Y centre channel kit and OE40CW-T3Y dash drivers up front, and the OE42-T3Y coaxials in the rear doors, for a top-to-bottom factory-sound transformation. The Safe and Sound team can advise on the right combination for your exact build and fit the lot in one visit.
