RAGE MI

Imagine the RAGE amps, with their features, performance and versatility. Their footprint is small for their performance, but can it be wrapped up in a slight different package? The RAGE MI, where the MI equals Mini does exactly that. Power, Performance, Perception & even smaller! It sounds too good to be true, but with a few redesigns we’ve made it possible.

Offering the exact same power as the RAGE 1200’s wouldn’t make any sense, so we dialled it back a bit. Not much though, the RAGE MI 1000.4 still offers an impressive true 4 x 175 W RMS @ 4 Ω. In dyno testing we were less than 6 % shy of that at 8 Ω! That goes to say these amps are beyond expectation.
The other RAGE MI offering is a 850 W mono and stable at 1 Ω. The same efficiency is clear here, 2 Ω dyno performance boasts more than 600 W. The near identical footprint of these 2 amps makes them perfect for sleek installs.
Any Level

The MI mono took notice of its RAGE 1200 siblings high level feature. The high & low level inputs offers greater flexibility, especially in vehicles where no RCA outputs are present. Given the modest dimensions, the amp can be hid away nearly everywhere (9.5 x 4.9 x 2.2″ / 24 x 12.5 x 5.7 cm). There’s no excuses for having insufficient bass response anymore. Even with a small amount of space for an enclosure, our shallow mount woofer RIOT FL10 solves that.
The RAGE MI 850 has a fully featured 12 dB / octave crossover section with 10 Hz ~50 Hz adjustable subsonic, 35 Hz ~250 Hz lowpass & a fixed 0 ~12 dB boost level @ 45 Hz. We even managed to squeeze in an external bass level remote port.
Packing the panel

The 4 channels of the RAGE 1000.4 MI takes up the entire panel. We didn't narrow it down with fixed crossover points & only 1 crossover type per stereo channel. The amp has fully configurable high & low pass crossovers on all channels. With the 50 Hz ~5 KHz adjustable frequency range the amp is ideal for anything , mid woofers, midranges, even bullet tweeters! Seeking more? The bridged configuration has more than 500 W available per channel, equalling over 1000 W RMS in total! With lowpass crossovers set accordingly, this tiny amp can used as a pure sub amp, or even as a tri-mode, with loudspeakers on the unbridged channels (front) and a woofer on the bridged channel (rear).

oh wow
Format: Kindle
I just knew there was something about Cooper! I’m wondering if he’s about to be included but damn I’m glad he’s at least not a rapist and creepy guy, he just got called on assignment and had to go! This should be interesting! She’s gonna run and then what’s his face is gonna grab her. I’m worried! Wow that was a great book and cliffhanger! Loving this!

Wow.
Format: Kindle
Okay I’m usually not one for stand-alone’s I’m an avid series reader but my goodness am I so happy I read this! This story was brilliant & so absolutely mesmerizing. I loved reading about each character and their struggles as well as what helped them to move forward. The ending definitely brought tears to my eyes so hard. I truly wasn’t expecting some of what happened in this story. There is about to be a spoiler I am going to reveal so please stop reading if you don’t want the spoiler !!!! ⚠️ ⛔️ ‼️ I loved that the author didn’t do what most authors do with irredeemable male characters. I truly was hoping that Nate Jr. would be apart of the pack after the way he treated Astrea bc he truly didn’t deserve it. Though I must say you did a wonderful job or redeeming him as a person. I cried my eyes out when he walked into the story. I was truly terrified he was going to be a bad guy to the end. However you truly did him such a justice by having him realize his faults & having him redeem himself in the most wonderful way. I’m so sad that he didn’t get to hear how much his brother loved him & forgave him before dying. But again you wrote that ending so beautifully & I just can’t express how much I loved this story & how you took a different route than most authors I have read have. You are a remarkable author Cinder Blaze & I thank you generously for creating such a masterpiece.

Omegaverse
Format: Kindle
I was pleasantly surprised by this omega verse book. This 1 definitely had a few new twists And I really enjoyed reading it. The main female character was a badass and awesome. She had 1 best friend I wish we could have seen a little bit more of their friendship in this book. Her relationship with the male characters was good not to contrived or super instantaneous. And we had some fun plot twists that I didn't expect. I wish we had more of a follow up on the situation with her family her background and her mother who was a wench. I would definitely recommend this book.

Wow. Just wow. An amazing read
Format: Kindle
This book was eloquently written, or should I say the authors writing style is very eloquent? I loved the characters, and the story was quite compelling. I absolutely loved the FMC, she's a BA who doesn't take any crap & gives as good as she gets. A certain person certainly got his just desserts & then some, the earlier scenes of which were quite satisfying, had me punching the air & everything haha. All in all 20/10, great read

My opinion
Format: Kindle
Let me preface this by saying I really liked the story and the characters however, this book is in desperate need of some sort of editing. It's not misspelled words or formatting, but continuous run on sentences. Redundancies within the sentences. There were a couple of paragraphs that I had to go back and reread 3 or 4 times. Overall, I'd say it was worth the read.
