  • best subs for your money
Size: Dual 12" D4 Loaded Enclosure
very amazing! they fit in my car PERFECTLY! (09 vibe) and they bump hard even while breaking them in still! they dont use up too much power either as i still have yet to get any sort of dimming lights (paired with a skar 1200w amp). these are very possibly the best subs you can get for the value!!

  • Sounds great, good value
Size: Dual 12" D4 Loaded Enclosure
This pre loaded box sounds great and his pretty hard paired with the Skar rp1500.1d amp, however I'm having problems with it clipping at high volumes. Need to dig into it a little more with a multi meter and see if it's from voltage drop or if I am just at the limits of this amp, but I didn't have this problem at all with my previous setup. Not 100% satisfied because of this problem, but I don't think it has anything to do with the subs themselves as they sound perfectly clear! No distortion at all (until it clips) and super clean lows, workers the best with bass boosted and down tuned songs! ... show more

  • So far so good (returning customer) So far so good (returning customer)
Size: Dual 12" D4 Loaded Enclosure
This is my second Skar subs and they are nothing but great. I previously bought a SDR 12inch single bundle, which came with the 800w amp and wiring kit. After 6 months, bass becomes an addiction so I spring for a dual 12 system same speakers. I am running it off of the previous 800w amp I have, and plan to upgrade it in the near future. But even the subs being underpowered by 400w the sound is insane compared to just the single alone. Fills the space better, and much better. Remeber 2 week break in period, don’t crank them max 24/7 or they will either smoke/break/tear etc goes for every sub. The car I have it setup in is an Audi TT, with is essentially a smaller Nissan 350z with the hatch back open in the cabin. Absolutely overkill for the car and I love it. ... show more
