Complete monster amps
Old setup was 2 hifonics brx 2400.1 at half ohm each and gained matched with two soundqubed hdc3 D1 18 subs. Was okay but wanted to do a single amp run and got this one for cheap used on a car audio forum. HOLY! This amp's power is off the charts compared to hifonics, worlds apart, even at full tilt, voltages dont even drop half as low as the hifonics. Big sound quality difference too. This amp really brings out the lows in your subs, even at very low power. Something the hifonics completely lacked even at high power.
Spend a little extra for toolmaker dual inputs, keeps the amp even happier and squeeze out a few extra watts.

Need power to make power
Huge potential, but with a stock Alt and 3 batteries - it just wants _more_ power. Ordering a Mechman 320A which should satisfy this beast.
2 x DC Audio Level 4 12" D1s @ 1 Ohm.
The Amp gain remote knob is somewhat... non-linear. Turn all the way down and it'll just about go silent, turn all the way up and from half way there's not much noise difference (though that may be related to my current power issues).
PS: These subs are also hungry, probably go a 5.0K with 2 x L4s - more room to play.

$75 e-Gift Card at Sonic Electronix
Got this bundled with the DC 90.4 which is a awesome deal. Everywhere else the amp was $500 sonic had it for less and it came with a $75 dollar credit so I get even more off my next purchase. Basically like getting the amp for $350 with my code taking off an additional 5%.

dc audio 3.5k
This amp is bulletproof. Currently running two group 65 batts. With Mechman 250 alt. Subs are skar zvx 15v2 s running .5 ohm. Simply devastating!

Sick...finally clean power!
Rockin way too many amps o we the years, not one single one compared to the clean power that this 3.5k delivers.
Same subs, same box...new amp new bass...it's way way louder compared to other amps that put out 4K RMS. There's something to be said about clean power. I am pushing 3 RE audio SXX, 1200 watts a piece, all together running at 1 ohm. It's pretty impressive for just 10's, it completely rattles your teeth, can't see (blurry) and wrecks your day haha.
Next is 3 12's DC audio this time, can't imagine how much louder it's gonna be, hope I don't wreck my 15 Focus ST
2 ott power, XS 3400, stock alt.
Summer's comin boys
