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.

    Car: Vauxhall Corsa - 2007>

    What’s the best amp to use for this as a single set up


    there isnt really a best amp for that product as such, alpine would recommend that the X-A90M would be ideal as it slighter higher rms rating than required but its better to have more stable power than an amplifier running at its peak all the time, however at a price point i would say the Inphase IPA2001 would be better suited, it will give you the power required at a 2 ohm load, and it is cheaper than the alpine equivalent. if you arent looking to break the bank then the Inphase would be the one i would personally recommend.

    the box is also a very important factor to consider as running the alpine subwoofer in a sealed enclosure will require more power from the amp, were as running it in a ported box that is designed around this subwoofer would give you the most output.
