Great amp for the price us amps does it again out performs rated power and runs cool no tacky lights or retarded heat fins not a big fan of the flimsy bottom cover but all in all a good amp got it running a sundown x18 d2 with ease

BEST AMP I'VE OWNED! SAME AS VLX & MERLIN SERIES FROM US AMPS! INCREDIBLE CLEAN SUPER EFFICIENT POWER! JUST AS GOOD AS SUNDOWN AUDIO OR DC AUDIO, SKAR AUDIO, CT SOUNDS, INCRIMINATOR AUDIO, DIGITAL DESIGNS AMPS! CEA 2006 COMPLIANT TRUE RATED POWER!

I HAVE 1 OF THESE BUT I JUST GOT ANOTHER TO LINK TOGETHER @ 4 OHMS TO PUSH MY 2 C2 AUDIO THREATCON-2 12D4 SUBWOOFERS IN MY OBCON DUAL LABYRINTH BOX TUNED TO 36 HZ @ 1.86 CU FT/ CHAMBER. WITH JUST 1 OF THESE CONNECTED TO 1 SOUNDSTREAM SCELL-400 CAPCELL @ 1500 WATTS @ 1 OHM IT HIT'S SOO LOUD AND DEEP THAT MY REAR VIEW MIRROR KEEPS MOVING UNTIL IT HITS THE WINDSHIELD & THE ENTIRE ROOF OF MY 1996 OLDSMOBILE 88 RATTLES LIKE IT HAS 4 12'S RUNNING IN IT. WITH 2 OF THESE RUNNING @ 3000 WATTS RMS @ 4OHMS IT WOULD BE UNREAL PUSHING CLOSE TO 3 TIMES THE RMS WATTS TO THE 2 C2 AUDIO THREATCON- 2 12D4 SUBWOOFERS. I COULD REALLY WIN CAR AUDIO SPL COMPETITIONS NOW. MAYBE HIT 160 DB'S WITH JUST 2 12" C2 AUDIO THREATCON-2 12D4 SUBWOOFERS & 2 RE AUDIO USX45KV.1 AMPS LINKED TOGETHER @ 4OHMS/ 3000 WATTS RMS. TOTALLY WELL WORTH EVERY PENNY EARNED WORKING YOUR BUTT OFF AT WORK!!!! BUY THIS AMP INSTEAD OF OTHER OVER INFLATED PRICED AMPS WITH OVER INFLATED POWER RATINGS. YOU WON'T EVER REGRET IT! I GUARANTY IT! YOU WILL BE SMILING CHEEK TO CHEEK WHEN YOU HEAR AND FEEL THE BASS THIS AMP PUTS OUT AND THE POWER IS SUPER CLEAN AND EFFICIENT WITH NO CLIPPING LIKE OVER RATTED AMPS OUT THERE. CLIPPING WILL BLOW ANY SUBWOOFER NO MATTER HOW GOOD IT IS.

*BEST AMP OUT IN THE MARKET BY FAR*CEA 2006 COMPLIANT*TRUE RATED POWER*

I HAVE 2 OF THESE AMPS (MLT'D) 3000 WATTS RMS @ 4 OHMS JUST INSTALLED 1 ON SATURDAY TO (MLT) IT WITH MY CURRENT ONE. GOT IT PUSHING 2 C2 AUDIO THREATCON-2 12D4 SUBS @ CLOSE TO 3 TIMES THE RMS AND IT'S CRAZY LOUD AND THE EXCURSION ON THE SUBS ARE HUGE AND IT FLEXES BOTH MY FRONT AND REAR WINDSHIELD AND MY WHOLE ENTIRE CAR RATTLES LIKE IT'S GONNA FALL APART. I'M TOTALLY IMPRESSED WITH THIS AMP AND WOULD DEFINITELY BUY 2 MORE TO BRING MY POWER LEVEL TO 6000 WATTS RMS (MLT'D) TOGETHER. BEST AMP I'VE EVER OWNED. I'D RECOMMEND EVERYONE TO GET THIS AMP. YOU WON'T REGRET IT. THESE AMPS ARE GOING TO BE POWERING 2 C2 AUDIO THREATCON-4 12D4 SUBS THAT I JUST ORDERED ON THURSDAY
