We congratulate you for researching this really HI-END amplifier.
The amplifier you have reviewing is a realization conceived by those who love music.

What is the "Duo" amplifier?

"Duo" is the natural evolution of our top of the range "Quattro" but in 2 channel edition.

It was created to provide similar performance at a more accessible price, while remaining faithful to the philosophy of achieving maximum sound quality.

It is the result of over 1 year of research and development to build a car amplifier with exciting performance.

Also for "Duo" the collaboration with Roberto Tognon was decisive.

His experience and knowledge of music do contributed to the creation and development of this project.
The "Duo" adopts innovative circuit solutions with top quality components specific for audio use and will allow you to enjoy your favorite music without losing any detail or nuance.

The excellent measurements and the very high reliability in very compact dimensions make the "Duo" the new reference for car audio 2 channel amplifiers in its price range.

IMPORTANT NOTES:
- Please do use at least 12mmq (6 AWG) power cable for the B+ and GND.
- Near the positive battery pole, within 30-40cm, it is necessary to mount a fuse, better waterproof if the battery is housed in the engine compartment.
- The ground connection is normally done by connecting the amplifier's "GND" terminal to the car chassis, when you do this, make sure you find a safe and reliable grounding point, if necessary, remove impurities, paint residues etc. to ensure the better contact.
- Install the amplifier away from temperature-sensitive components.
- keep at least 5 cm of air above the amplifier.

Proper installation guarantees better performance, follow these notes for installation.

- Use only shielded cables to connect the audio signal between the car radio and the amplifier, it is not necessary to use very expensive cables, but do NOT use bad cables!

- The use of good quality RCA connectors guarantees a good contact, lasting over time and reliable even after several operations of insertion.

- Shielded cables must be kept at a minimum distance of 10cm c.a. from any generators of car noise, such as power units, pumps, cables, etc.

– For power connections use only good cables, of suitable sections and protected in the engine compartment.

The cables for car-audio applications are very flexible and therefore easy to install.
- Carefully take care of the laying of the cables and operate in order to follow different routes to signal cables from power cables.

- It is a good idea that the GND ground of the amplifiers is connected to the same point, together with the audio source's same ground.

– Fix the amplifier securely, to avoid its movement and then the cables jostling.
– The top side of amplifier has to have free air around, at least 10cm.

– A well-designed and equipped system may involve the collection of various devices, if this happens, ensure adequate ventilation of the place where the amplifiers are installed
perhaps with the aid of an additional forced air flow by a fan inside the various compartments.

This amplifier is designed to work only at 12V DC from the car battery, do not attempt to power it with AC or different voltages!
Install the device in a solid way that does not affect driver's guidance
Do not place the device in very hot places (such as the engine compartment).
Make sure that the installation location is not subjected to high humidity and / or splashes of water.
Perform solid and safe connections, using only cables of adequate section and type.
It is absolutely essential to install a fuse of adequate value near of the battery.
In the installation / uninstallation and maintenance operations it is absolutely necessary to remove the fuse located near the battery.

If the device is subjected to severe shocks that could visibly damage the chassis, let it be viewed by the service center or by a professional installer.
Keep the device clean and do not obstruct normal chassis ventilation, do not use aggressive detergents for cleaning.

The maintenance's allowed to the user are set sensitivity, display setting and the replacement of the fuse with identical characteristics, (to be performed as described in the "Diagnostics" paragraph).

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat. It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.

Strong Omegaverse Comfort and a Attention Grabbing Plot
Format: Kindle
Jillian West never misses when it comes to Omegaverse, and Not Ready is no exception. This story was the perfect blend of cozy comfort and emotional depth while still delivering a strong plot. Vale is such a powerful heroine, she is strong, capable, and determined but I love that she still allows her pack to love and take care of her. It’s that balance of independence and vulnerability that makes her so relatable. The relationship dynamics were amazing: Bishop is steadfast and completely head over heels, Mercy is skeptical but protective in his own way, and Holt is the hesitant one whose slow fall is so satisfying to watch unfold. The romance hits that sweet spot between insta-love and cautious build, keeping me hooked the entire way through. And that ending. Oh my god, the cliffhanger! I need the next book in this duet immediately.

Interesting
Format: Kindle
So I will say I enjoyed the story, for sure had its moments where it dragged but it was a great story. I really liked that omegas picked their alphas/make the pack. Normally the Alphas make it and the omega fits in with them which is great but I enjoyed this new version where all the power basically went to the omega. It was a nice change of pace. I can admit some of the weird bedroom stuff with her being pregnant was odd, it’s really not hard to do stuff when pregnant (I know I’ve had two and it’s normal and even encouraged at the end especially if you want the baby out). But I like the story as a whole and will read the second, I do hope the next one isn’t dragged bc it stopped being action or tense after she met her alphas and I don’t think it was brought up or properly done when they tried to do it. More sweet after she left.

I’m a little disappointed.
Format: Kindle
I usually like Jillian West’s books but this one was missing a lot for me. The pregnancy didn’t come across as real. She’s on her feet for 12 hour days but is perfectly healthy at 8 months pregnant? Yet the week she moves in all of a sudden she’s not? She is planning on actually running during one of the plot buildups. But at 8 months pregnant that’s incredibly hard to do. The lack of breathing ability and lung space, the change in body center, mass, and gravity. All of it prohibits running, unless you’re an athlete this didn’t come off as at all realistic. I didn’t feel any connection with the alphas. There wasn’t any emotional connection. It could be because of the tense it was written in. But I didn’t get any deep feelings out of this. It came across as checking off boxes. Even the spicy scenes weren’t really believable for me. I wanted to see them fall for her, and it just kind of all fizzled. Even Bishop. One thing I did really like was the ending. I did not see it coming and I’m interested in reading book two because of it. But on the whole this book was mostly disappointing for me.

Vale is an 8 month pregnant omega working as a waitress at a strip club and a cam girl. She starts to get very creepy vibes from a regular at the club, and her baby daddy ghosted her. She has had an online relationship with a man named Bishop through her cam girl status. One night, bishop was paying to watch her sleep and ansthe creepy regular Andrew break in and watch her sleep he tells vale to come to him at his business now. She flees and finds herself at a large security company with some.hot of alphas who are there to help her. This imegaverse is a little different than I have read, but I am thoroughly enjoying it. Vale is not a traditional omega she was raised by a single beta mom, and the alphas are not normal alphas they have never really loved pack life. But they are ruthless mercenaries. They need her, and she needs them. I love the aspect of the stalker and now the plot twists at the end, so so good. Sometimes, it seemed a little slow and stale mated, but since this a duet, I think It was just her starting to have Vale get to know her alpha suitors. Cliffhanger for sure with this one.
