Upgrade from your OEM speaker system toward a bigger, fuller, high-performance sound with the Polk 4-Inch 135W Speakers w/ Kicker CS Series 4-Inch Coaxial Speakers. The high-grade materials used in our DB+ Series ensure you get an audio system that’s designed and engineered for clear, full range sound that will last much longer than your factory setup. These speakers also feature non-resonant materials so you get extremely clear highs, mids and lows no matter what you’re listening to through our patented Dynamic Balance (DB) Technology.

The new DB+ series has been updated so you can enjoy a simple drop in installation in any vehicle including cars, boats, ATV’s -- you name it. Its new shallow tweeter design ensures your factory speaker grille re-installs with ease for a flush, seamless look. This quick and easy experience also ensures a faster installation process so you can get back to what matters with our great sound always along for the ride.

Also included are the Kicker CS Series 4-Inch Coaxial Speakers so give your factory speakers a boot and introduce them to these. These 2-way speakers jam at 150 watts max each and significantly upgrade your sound. The stamped steel framework supports the rigid polypropylene cone with Extended Voice Coil technology. The speakers also features a balanced dome tweeter, no-protrusion polyether imide balanced dome tweet, and 4 ohms impedance. These speakers perform best when paired with a CX amplifier and on 50 watts of power.

Freight Shipping Information (LTL)

Some items are too large to be shipped with a regional carrier, FedEx, or USPS, and we ship these items with our freight carriers.

Please read the information below so you fully understand the delivery process and requirements.

Required Actions

We will need your phone number for the delivery. The carrier will need to call you in order to set up a delivery time. Please make sure the number you provide during checkout is the best one to reach you. If paying with PayPal, please make sure the number on your account is accurate.

You'll need to inspect your package upon arrival before you sign. If your order arrives damaged, you should sign "DAMAGED" on the delivery receipt. If the item is damaged to the point that it is not usable, you can refuse the item.

Please notify and, if possible, send photos of any damage to vminnovations_help@email.spreetail.com, along with your order number. A member of our Customer Experience team will reach out to you with further instructions.

Delivery Information

At this time, we do not offer "in-home" deliveries. Your shipment must be delivered to the curbside and will require a signature. Please be sure you are able to move the item after it arrives, as the carrier will not be able to assist.

We do our best to ship orders as fast as we can. If you need to cancel your order, please let us know as soon as possible by calling our Customer Experience team at 866-639-9320. Please note that if we are unable to cancel your order before it ships, you will be responsible for the shipping charges.
