Am currently looking at subwoofers to upgrade from my lowly Powerbass S-10D's. Have been running a Lightning Audio 1001.d monoblock @ 1 ohm for the last year, and every time I get it cranking, the amp shuts off after 10-15 minutes, blowing fuses. I am running a 250 amp alternator, and a brand new 1000ca/800cca battery, with 1/0 run back to my distribution block, and a 14" 4ga run to the amp, with the big 3 under the hood. Will be adding a second battery, under the hood, as there is a second battery tray. I really don't want to run much more power than what I already have, as I don't want to get into having to add a dual alternator, or putting another battery in the back. Probably looking at a1200-1500 watt amp, possibly Skar or Audiopipe, just depends on what I can find for a deal.
The Powerbass subs are only rated at 350 watts rms, I'd like to be able to run a clean 600-750 to each. I haven't found much out there for a sub that has a high sensitivity, other than the Dayton's below. Most 10" subs that can handle 500 watts rms or more only have a sensitivity from 83-87db, these Dayton's are supposedly 90.5db. If I remember correctly, it takes double the power to achieve 3db more in output - if that's so, then these Daytons with 600 watts would have the same output as a different sub pushed by 1200 watts at a 87.5db sensitivity, or 2400 watts pushing a sub with 83.5db sensitivity.
I know that Dayton is primarily a home audio company, but these have me intrigued. Specs look decent, and what other content I've found online seems to agree.
If not these, then make another suggestion for a higher-sensitivity 10" sub, that will work in a 1.25-1.3cu ft enclosure (mine is about 2.8 cubes, less sub and port displacement).
1. Product: 2 Fi SP4 18s with Carbon Fiber Dust Caps
2. Specs: Both are dual 1 ohm (0.7 ohm)
3. Description/Condition: Ran them for a little under a year on low power (Audioque 2200). Magnets have some scratches but the surrounds, baskets, spiders, and coils are in excellent condition. Does not include the original gaskets. A couple of the pictures are next to a 10" Kicker "Competition" (lol) for size comparison.
I threw out the original boxes some time ago, but Fi was nice enough to send me two brand new boxes to ship them in. So these will ship in original Fi packaging.
4. Price: Asking $900 SHIPPED OBO for the pair. Because they are dual 1 ohm, I would like to keep them as a pair. NO TRADES, just trying to get rid of all my stuff.
I'm located in Huntsville, AL 35810. Would be willing to drive to meet someone within reason.
