When One Is Just Not Enough

This combo features two 12" MB Quart RLP 304 Dual 4 ohm Reference Low Profile series subwoofers. The subwoofers feature a combined RMS of 800 watts, giving you some real strong bass. The woofers are equipped with an injection molded polypropylene woofer cone and foam woofer surround. The cone and surround materials will offer increased performance, rigidity, and strong power handling capabilities. The woofers also feature a shallow mount design making them ideal for small and compact areas. These subwoofers work best in small sealed enclosures.

Here at Sonic we understand that sometimes one subwoofer is just not enough bass. So we are happy to introduce our subwoofer pair combos. With these combos you can purchase two subwoofers to get the bass you are really seeking for. The best part of these combos is that we are able to offer some savings by buying the pair together instead of one at a time. So take a look and find the best pair for you.

I recently installed two of these in an 07 Toyota Tundra in a down fire sealed box with a memphis pr 500.1 wired at 1ohm and the sound is nice. I wasn't sure about the flat subs at first but after hearing them i ordered 4 for my GMC 2500 crew cab, can't wait for them to come.

A great deal on name brand speakers. I looked at many sites and found Sonic to be the best place. Service and communications from them throughout the purchase was excellent. Thanks.
