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).
Looking for a bit of advice on purchasing a new amp/amps.
Ill be running a pair of D2 crossfire XSV2 15s tuned around 30hz.
My dilemma is whether I would get more out of (ie more power, less rise):
A pair of 2.5k amps (probably Skar 2500), bridged and wired to 1ohm each
A single 5k amp run at .5ohm
2 runs 1/0 OFC (one is knu, other is memphis) and 1/0 Big 3
Kinetic HC2400 up front
3 deka group 34 AGMs in the back (55ah a piece, 750cca)
270a-320a altenator (will be added after amps)
Thanks in advance for any help!
