Product Research

Features

Size Classification Note: Some manufacturers, including DS18, call this size speaker a 6½. Because it requires a larger cutout than a standard 6½, Crutchfield has traditionally referred to this size as a 6¾. Please enter your vehicle information to confirm fit.

Crossover: Although no crossover is included, DS18 recommends using a 160 Hz high-pass filter.

Q
What amplifier should I look for to power 2 of these speakers along with a set of tweeters?
kyle  Jul 01, 2025

A
There are a lot of amplifiers that can be used to power these as well as any tweeters you might match with them. I recommend contacting a product advisor by calling 1-800-324-9695 to discuss the tweeters you will get with them and any other gear you have to get a personal recommendation on an amp to power them

A
These are 4 ohm speakers and cannot present a 2 ohm impedance. We have product advisors here that can be reached by calling1-800-324-9695 who can help with building a matched system

While the DS18 PRO-X6.4BM is highly sensitive it would perform best using when using an aftermarket amplifier, Valentino. If you need help choosing the right speakers to work best for your specific vehicle and goals, do not hesitate to give us a call and an Advisor would be happy to help!

Greetings Anthony. Thank you for your question. There are no dumb questions. Next to our price on that product it will say PAIR or EACH. In this case these are sold individually.

Hey Kerry, DS-18 speakers are designed in mind that you will want to give them as much power as you can to get the volumes they market.
