Kicker 45L7R154 Overview
Tried, tested, and true. That’s how one would describe the Kicker 45L7R154 15” dual 4-ohm voice coil car subwoofer. For years, Kicker has made their square subwoofers and for years, they have blown away the competition. It boils down to simple math: a square subwoofer has more surface area than a conventional round subwoofer. More surface area = more bass.

The Square Subwoofer
A long time ago, Kicker engineers designed and developed a unique concept: the square subwoofer. The Kicker 45L7R154 15” car subwoofer proudly carries on the legacy that its forefathers established. You simply won’t get the impact or the performance from any other subwoofer on the market. As we mentioned earlier, the math is simple and the results are impressive.
Stitching: Better than Glue
Many subwoofer companies employ glue and other adhesive products to adhere the cone of the subwoofer to the foam or rubber surround. That’s not the case with the Kicker L7R subwoofers. Using an eye-catching red thread, the cone and rubber surround are married together with a long-lasting bond. Not only does it look gorgeous, it adds a lot of strength to that bond. The result: you get one of the best-built, well though-out subwoofers to date.
Dual Voice Coil Design
The 45L7R154 car subwoofer features a dual 4-ohm voice coil set up. This is done for a couple of different reasons: it allows the subwoofer to handle more power with ease and it also helps wire one (or multiple woofers) in either a series or parallel configuration to change the final impedance of the set up. By doing this, you can help your subwoofer extract more or less power from the connected amplifier.
Advanced Thermal Management
As you demand louder volume and more output from the Kicker subwoofer, heat is going to build up. The engineers over at Kicker wanted a way to quickly and easily dissipate this heat so it’s not building up in the subwoofer and causing it to fail. The UniPlate™ pole piece and backplate were designed to manage this heat. They wick it away from the internal components of the subwoofer and dissipate it into the surrounding atmosphere. A subwoofer that runs in a well-managed thermal environment is going to sound great and last a long time.
Allow Us to Suggest…
To properly power this subwoofer (assuming you are using only a single 45L7R154 subwoofer in your setup and the voice coils are wired in parallel), we would recommend a single-channel (or monoblock) amplifier that is stable at 2 ohms. Ideally, the power output of this amplifier at 2 ohms would fall around 900 watts.
