Is Quantum on Sale? November 2026

Questions and answers

What makes the Quantum QBC1-10 different from a separate sub and amp?

The subwoofer, sealed enclosure and amplifier come assembled as one unit. That removes matching an amp to a sub and building or buying a box. The trade-off is less flexibility to upgrade one part later.

Does the QBC1-10 fit in a trunk or hatchback?

It is a 10-inch loaded enclosure, so check the listed dimensions against your cargo area before buying. Sealed boxes of this type are usually compact enough for most trunks and hatchbacks, but measure first.

What power and wiring does the built-in amplifier need?

It runs on the car's 12-volt electrical system and needs a fused power wire from the battery, a ground and a remote turn-on lead. Check the product page for the amp's rated power and recommended wire gauge.

What warranty does Quantum offer?

Warranty terms vary by product and seller, so confirm the coverage period with the store you buy from. Keep the receipt, since it is usually required for a claim.

Can I return a Quantum subwoofer enclosure if it does not fit?

Returns depend on the store's policy, and car audio gear often has to come back in its original packaging and unused condition. Check the return window before ordering.

Are there Quantum discount codes?

Deal.ai checks what Quantum products actually cost at every store, so a real markdown shows on this page as a deal as soon as it starts, and each product's page has its price history to tell a sale from its usual price.
