Skar Audio SDR-8 D4 8" 700 Watt Max Power Dual 4 Ohm Car Subwoofer

Nice design comes well packed. Well built just in the break in period great sound

This sub kicks hard and sounds great. At 450 watts on a alpine amp in my 2001 gmc jimmy it pounds so hard turned up that after ten mins I have to turn it down because my head starts to hurt. Definitely can leave a gun in the drum.

This Skar audio SDR 12-in D4 wired in parallel to 2 ohms and is 600W RMS and I'm only pushing 350 watts into it and it is so loud it hurts my ears being right behind the driver's seat in my Silverado. It was decently priced and even better when they go on sale. I used to have the IX 12-in D4 wired to 2 ohms as well and this speaker blows the other one out of the water with its deep lows and impressive loudness. Definitely worth giving it a try for a budget subwoofer it performs phenomenally. I can only imagine after the break in period. Definitely worth picking one up or two for that matter depending on your setup configuration. One is definitely plenty for me where I have it located. It shipped really quickly as well and I got it on time with my free shipping Amazon prime. Just remember to break it in respectfully. Skar audio recommends a minimum 24-hour break in. At half to low volume and at half too low power just to break them in properly. I only drive about an hour a day so it won't take me close to 24 days to break mine in but once they're broken you can crank up the wattage and the volume and they will sound amazing. I know my IX12 sounded amazing and over 2 years later still performs well. I put the IX12 in my wife's Kia forte and she loves it and it thumps really hard. My point being is if they're properly broke in they will last as any speaker should if properly broke in and properly powered with clean power.

Used for a home theater, sounds pretty good

Wired up for 8 ohm as a replacement for a 30 year old THX ultra SW-X1 passive subwoofer(120 litre cab) Not quite as smooth on the upper end as the OEM but has great extension and good beefy sound with tons of SPL available running on my Kenwood Basic M2A power amp. (220 RMS both channels driven@8/0.004%,and 526w dynamic power, per channel) Compared A/B with a Soundstage PS12D4 driver from the same price class(and same cabinet/room/amp) it was hands down to the Skar for low end extension. Definitely buying three more for my other cabinets. Both subs ran @80hz LPF.
