Questions

Will these fit my car?

6.5" is the speaker size. Whether it fits also depends on the mounting depth, 43.2 mm (1-11/16"), and the opening in your door or dash. Send us your year, make and model and we'll confirm fit and the adapters you need.

Do I need an amplifier?

No. They run fine on a factory or aftermarket stereo. An amplifier gives them more headroom and clearer sound at higher volume.

Do you install speakers?

Yes, at our Markham shop, with the adapters and harness matched to your vehicle.
