2 15s or 1 18?

[HunterZ71]

i think i am selling my 2 12" AQ SDC2.5 to a buddy and i am looking to get some bigger subs. I am considering getting either 2 AQ SDC2.5 15" or 1 AQ HDC18 copper coil. I have an AQ1200D amp that will be powering the sub(s). Which of these of the combos would louder?

you'll never know unless you try both.. 2 15's is more cone so on the same power, in theory the 2 15's should get louder but the HDC18 is a better woofer so it could be more efficient

I was running 1 Fi BL 18 on a Rockford Fosgate t1k and I hit a 145.7db so its possible for that 1 18 to be louder

either way you are running some great products!!

i'd do 2 hdc3 15's on 2 aq 1200 strapped @ 1ohm each amp would be seeing a .5 ohm load
i run my aq2200 strapped @ .5 ohm daily all day long

id run 2 hdc15's with at least 4000rms...
the new aq3500.1 does 4200rms which it perfect.

or step up to something stronger like dc level4xl's...with at least 4000rms as well...

with what amp?

 

[HunterZ71]

I would love to run anything at 4000 watts but I don't have the funds for an amp or amps that could do it. I think I am leaning towards the 18" HDC3 because there is more upgrade potential later on when I do have more money to put into it. That and I have never heard a good sounding 18 all I've heard are cheap ones in shit boxes and I know i can build a box to make it sound good.

im running 1 18 BTL and its loud as ****..way louder then and of the 2 15s ive had or heard..plus you get the wow factor having a 18

 

[droppedHoe]

you'll be surprised.. you can get a true 4000+rms for as low as 400 used 550 new
the hifonics 2610 will do plenty and strap a pair of them...5000+rms for $550
gotta friend that wants 4 in his truck with 4 15s...over 10k rms (of course with the elec.system to back it up

a aq1200 will piss off a hdc18

 

[HunterZ71]

The aq1200 should do decent enough.. the subs are rated for 1000 rms and im just running the copper coil for a daily beater i don compete or anything so the 12-1300 watts rms at 1 ohm should be ok i would think

i should be enough for your daily use unless you are like me, i beat my system to death going down the road and then when i get to a good chill spot i open the hatch and let it rip. whenever i get enough funds i gonna find a good used dd 9518 and sundown saz-3500 and run it @ 2ohms and call it a day.
