The extremely compact QUANTUM QM-TWO power amplifier has long been one of the top sellers in the ESX amplifier portfolio. Since the larger QM and QL models are now available in black and enthusiastic ESX Quantum fans want to install the small QM-TWO in the same look, we are now presenting the new QM-TWOv3 as an exclusive "Black Edition". The reasons for its success are literally "obvious": At just 7.5 x 12 cm, this small Class D power amplifier is an incredibly powerful powerhouse in miniature format, ideal for driving many speakers up to 2 Ω.

With 2 x 150 watts RMS at 2 Ω, the V3 can easily drive almost any speaker. Compared to the v1 version, the power has been increased by an impressive 25% with the same size. With a bridge power of 300 watts RMS, the power amplifier is even able to properly supply subwoofers.

Despite the 25% increase in performance and the unchanged heat sink, the QM-TWO v3 achieves a sensational efficiency of 85%. This not only keEPS® power consumption low, but also saves you from having to use excessively thick power cables.

The QM-TWOv3 is very well equipped. The often required high-level inputs with plug-in mini-molex connectors and automatic switch-on are equipped with proven EPS® technology. This makes it possible to integrate the QM-TWOv3 into modern vehicles with factory systems and loudspeaker diagnostic systems without errors occurring in the on-board electronics. In addition, ESX does not do without classic cinch inputs: The QM-TWOv3 can also be connected directly behind DSPs or high-end radios at any time.

If you own a diesel engine, use this.
Size: 128 fl. oz, 1 Pack
For diesel owners looking to protect their fuel system, Hot Shot's Secret Everyday Diesel Treatment (EDT) is a heavy hitter in the world of additives. This 1-gallon jug is designed for the long haul, treating up to 1,280 gallons of fuel, which makes it incredibly cost-effective for daily drivers and fleet owners alike. The primary draw here is the 7-point cetane boost, which noticeably smooths out rough idles and improves cold starts. Beyond performance, it serves as a critical insurance policy against modern "dry" Ultra-Low Sulfur Diesel (ULSD) by adding essential lubricity to the fuel pump and injectors. It also features a demulsifier to help separate water from the fuel, preventing corrosion before it starts. While the 1-gallon bottle is bulky and requires a smaller dispenser for easy pouring at the pump, the peace of mind and improved MPG make it a staple for maintaining a healthy engine.

TDI Seems To Like This Stuff. A Must For US D2 Fuel.
Size: 1 Count (Pack of 1)
After purchasing our 2012 VW TDI diesel at 140K miles I started researching best practices to keep these little engines happy. What I read was that the US has some of the crappiest quality D2 diesel on the world stage. Even Canada's diesel is higher cetane and lubricity rated than the States not to even mention Europe which has WAY higher standards than us. The weak point of these TDI engines seems to be the high pressure fuel pump (HPFP) that is crank driven to enormous pressure for the injectors to to their thing. If these HPFP parts fail on common rail engines they can literally grenade and throw shards of metal everywhere within the downstream fuel system ensuring a VERY expensive repair if not destroying the engine altogether. The lubricating property of the fuel plays an important part in keeping these pumps working properly. There even seems to be some data supporting Canadian operated TDIs have fewer failure rates of the HPFP than stateside fueled vehicles although nothing had been officially published to my knowledge. Sulpher in the diesel had beneficial lubricating properties but was bad for the environment and subsequently removed from D2 by the EPA much like leaded gasoline of yesteryear. So the second tank I ran in my TDI was Hot Shot's EDT. I can't comment on the comparative difference as I ran this from almost day one. What I like is the claimed increased lubricity and cetane boost that is supposed to bring our crappy D2 up to reasonable levels the rest of the world enjoys. Fuel economy seems fine but playing with a low spun turbo and the subsequent torque is sometimes too irresistible to give fuel economy a fair chance. Besides, I need to blow out all that accumulated carbon :) I like the fact that the Hotshot's EDT seems more concentrated and affordable than the competition. 1oz for a tank is almost a performance treatment for my TDI. It's a negligible cost for a fill up and I hope they keep it that way. My dislike might be the one thing other people love about this product and that's the bottle. The bottle is meant to be squeezed to get the measured amount in the top fill area so measuring is easier. My concern is the filler neck is not long enough to cram into the filler to avoid spilling without a funnel and diesel doesn't do many favors to paint. My workaround was to save the empty bottles from other gasoline treatments and use a syringe to fill 1oz amounts of EDT and place in the trunk of the car in double plastic bags. Seems to work fine although the kitchen was probably not the best place to do this since it doesn't smell like flowers. Next purchase will likely be the bulk bottle. It's kind of a shame we actually need this kind of protection now since the US fuel standards are almost non-existent. Even B1 blended bio diesel would be a huge improvement in lubricity but not available where I live. Thanks Hotshot's...Good stuff!

Recommended by John. So far great additive for the CP4
Size: 16 Fl Oz (Pack of 2)
I have a ‘22 6.7 Powerstroke w/27k and pull heavy trailers in FLA. I’m worried about the (disco party). John I believe from the Ford Dealer in Hereford, Tx recommended this. I run 2 oz per fill and will see what happens. I’ve got Five fill ups on it now and seems to help responsiveness. Proof will be in the pudding. So far I’m pleased

Quieter and more mpg in TDI
Size: 1 Count (Pack of 1)
Didn't really believe the hype. Did a little research and watched Project Farm and decided to try. Im not a snake oil guy....but I will say my 2013 common rail TDI is quieter and I get a tad more fuel mileage. Does it pay for itself? Well, it does get better mpg, but I feel the reduction in noise most likely relates to less wear and tear and thats good enough for me. Im only using 1oz per fill up (about 14 gallons) so it lasts a very long time. I get 40mpg and im not light footed.
