The T3-1000D is, as you may have guessed, a class D amplifier. It is rated to produce 1000 watts into a 4ohm load and 1200 watts into a 20hm load. This newly designed amplifier is housed in a large aluminum heat sink with small fins running across the top, with an illuminated Ultimate badge in the center. Along the smooth lower 1/3 of the amp is a pair of digital displays that shine through chromed shields. These displays monitor amplifier voltage and temperature. The heat sink has large aluminum end caps and whole thing is left in a raw lightly brushed aluminum finish.
On the left side of the amp are the inputs and signal adjustments. On the left side are two molex sockets. The furthest to the left is labled 12+V output to power some optional accessories like a capacitor with an LCD power read-out. The six-pin socket can be used with a supplied pigtail harness to feed the amp speaker level signals.
The amplifier has a very industrial theme, thanks to the liberal use of hex-head socket screws. The removable end-caps each have a pair of large screws, the Ultimate logo is held together with eight screws and four more in the displays. I really like the look. Industrial yet contemporary in theme. The amplifier's sensitivity can be adjusted by a gain control that is located beside a pair of input/output RCA jacks. the gain is adjustable between 0.25V-8V beside the gain are three processing controls. First is a three-position subsonic filter switch. you can select 20-30-40hz. But the filter cannot be shut-off. The always on low-pass filter is adjustable between 40hz-200hz finally a bass boost control that will allow you to dial up 18db of additional thump. A six-pin phone jack labled RVC will allow you to connect the supplied remote volume control ****.
Which by itself is unlike most amplifiers on the market. It features a small three digit 70segment LED display. This display shows battery voltage, indicates when the amp is clipping or a fuse has blown or overheated. This is great information to have on tap when brutally punishing your amplifier.
The opposite end of the amp is home to the speakers and power connections. The power connections are absolutly massive and will easily accept 0awg cables. The equally robust speaker connections will accept freshly stripped 8awg. Their are two positive and two negative connections. A dual purpose LED between the terminal blocks indicates the amplifiers status. The chromed Ultimate logo illuminates in blue when the amp is operating and should something go wrong it switches to red to let you know when it's time to investigate.

Two large 30A relays ensure the amp powers up with nary a squeak from your subwoofers. Worth noting are the switching devices that are clamped to the heat sink at an angle leaning away from the board. This means there is a massive amount of heat sink underneath them to wick away potentially damaging heat.
When connect to a 4ohm load and fed with 12.77volts the amp produced a beefy 1369.0 watts at 1%distortion at a efficiency of 77%. Upping the supply voltage to just under 13.5 volts sent the output power sky-rocketing to 1608while drawing 155A of current. This is very serious power into a 4ohm load. Something that is very hard to find in today's market. Most amplifiers make their power at lower impedances. The factory ratings for a bridged 2 ohm load at 13.8 volts is 2700 watts at 210A.
The industrial design of the T3-1000D will definetly make it attractive to mobil audio enthusists. It produces an incredible amount of power at a 4ohm load at very good effiencty. If you are looking for a solid low frequency producing machine be sure to take a look at the T3-1000D.
