Key Features

2250w 12" Dual 4Ω Voice Coil Subwoofer - Alpine Car Audio Systems R-W12D4

Type-R Subwoofers have been known for their power handling, clean output and deep bass excursion at a mid-line price. The R-Series Subwoofers feature a Kevlar-treated cone for durability. The combination of this cone with the Santoprene surround allows the Subwoofer to deliver 19mm of X-max, for incredible, hard-hitting bass. A new method of attaching the spider and cone to the voice coil ensures not only rigidity throughout the motor structure but contributes to the Subwoofers increased accuracy.

    What amp is best for these sum my bmw f30


    Have a look at the below amplifier IPA1601. You will also need a line out converter. For the price, the DB Audio TREX12 is a much better subwoofer.
