Product Overview

DXQ6C2

6.5" 2-Way Component Speaker Set with Yellow Straw + Composite Foam Cone — 150W RMS, 4-Ohm

DS18's DXQ6C2 brings crystal-clear, full spectrum sound to car audio enthusiasts looking for a quality boost. This component set — 2x woofers, 2x tweeters, and 2x crossovers — offers a natural, distortion-free frequency response from 35Hz up to 20kHz, handling 150W RMS and 300W MAX with exceptional clarity and impact.

The 6.5" woofer features a premium yellow straw and composite foam cone in an aluminum basket coated with a black finish. Its 1.2" voice coil is wound with superior SV wire and paired with a rubber surround to enhance durability and reduce resonance.

The 2" silk dome tweeter delivers a sensitivity of 90dB and clean frequency response from 800Hz to 20kHz, producing smooth, natural tones while eliminating distortion.

A 2-way passive crossover set at 2kHz with a 12dB/octave slope keeps each driver in its optimal range, with tweeter attenuation adjustable at -4dB, -2dB, and 0dB to fine-tune your soundstage.

Push-type 14-gauge speaker terminals and a standard 5.7" baffle cutout with a shallow 3" mounting depth make installation straightforward in most doors and panels.

FAQs

Please read our FAQs page to find out more.

RMS vs. MAX power — which number do I actually care about?

RMS is what your gear handles continuously; MAX is the short burst it can survive without complaint. Match your amplifier's RMS output to your speakers' RMS rating — sizing off the MAX number is how magic smoke gets released.

What does the IP65 rating on DS18 marine gear actually mean?

It's dust-tight and rated against low-pressure water jets from any direction — built for spray, rain, and the occasional wave over the bow, not for full submersion. If something's going somewhere it could sit underwater, that's a different conversation entirely.

How do I match an amplifier to my speakers without guessing?

Add up the RMS rating of everything the amp will power, and pick an amp whose RMS output (at your speakers' impedance — usually 4-ohm) lands close to that total. Undersized is thin sound; wildly oversized is a fast way to blow a voice coil.

Can I mix marine-grade gear into a standard car audio setup, or the reverse?

You can run marine-grade gear in a car — it's just over-built for that environment, no downside besides cost. Running non-weatherproof car audio gear in an open UTV or boat is the direction that causes problems.

What gauge wiring kit do I need?

It scales with your amp's power draw and the length of the run — DS18's OFC kits come in 4-gauge and 8-gauge for a reason. Undersized wiring on a high-draw system is a voltage-drop and heat problem waiting to happen; when in doubt, size up.
