So, I was super stoked when I started my latest project which was getting 4 12's shoehorned in the Ranger and getting them to sound good all around sealed.
Long story short now it's in, sounds amazing with any track you throw at it, but it leaves me wanting more lows, after 37hz it flattens, is audible, but around 30 it just shakes the truck. I want what I had in my hatch, a little bit of port action. I used to put down 139 on music with a Orion XTR 2 12 tuned at 32hz.
4 HFi12D4. The BEST sub to be had under $50. I've installed so many of them, I love them, they're cheap and I have enough laying around in case I roast one, haven't yet though and I slam it full tilt all the time for extended amounts of time. The amp doesn't even get warm slamming constant, best class D I've owned to date. Voltage hangs right around 12.6 after a little bit of slamming. Next thing coming is a battery.
These are getting around 700 total RMS, about 175 RMS a piece @ 2 ohms, the amp is 1 ohm stable, HFi1000.1D, gonna play around with wiring when I get the tme.
But here's a few vids on my youtube channel, shitty camera, but it works. Don't rag on the music either, It's all decaf "enhanced" you'll find his tracks on the SMD forums. When I;m showing it off, that's all I use, that and bass mekanik and tones.
These aren't broken in yet in the vids, now they are, so I'll be making another vid on the way home. Gains are higher now, whams better than in these vids.
