Serious marine sound, made simple. The M5 amplifiers feature the next level of Element Ready™ design from Rockford Fosgate that’s built as rugged as the outdoor environment it’s used in.

Rockford Fosgate amplifiers are known world-wide for producing more power than their ratings suggest. The M5 amplifiers are the first series based on new industry standard Dynamic Power ratings, bringing their conservative ratings to the forefront. Engineered from the ground up and purpose-built to deliver more output where you actually hear it, this is real dynamic power that performs not only on paper, but performance heard through the musical experience. You’ll see two amplifier power ratings, the traditional Continuous Power output, and the new Dynamic Power output, both tested in accordance with the CTA-2006 specification. Consider Continuous Power as wattage developed on the test bench for comparison against other amplifiers in the same class, and Dynamic Power as real-world wattage when connected to a speaker load, listening to music. Either way you look at it, Rockford Fosgate is proving – once again – these amplifiers are powerful enough to drive any speaker or subwoofer you throw at them.

One sitting read
Format: Kindle
I think I might have a thing for text message chains and love letters. This book is full of witty, sexy banter. My personal faves. Colin: What would you do if you accidentally texted the wrong person something naughty, and they responded in a way that surprised you? You were so intrigued that you kept coming back to this faceless number. She's sexy, straightforward, effortlessly funny, and you can't stop thinking about her. And then you realize this mystery woman is none other than your unwanted roommate and best friend's sister. She's a dumpster fire in real life, but what if there was more to it than that? Olivia: Who hasn't started an apartment complex on fire, lost their job, and forced to move back home and live with their brother and his insufferable best friend? Add in some mismatched socks, and this is a typical Tuesday night for Olivia. I devoured this book. I opened it thinking I would read a few chapters and fall asleep. 4 hours later, I finished it. IN.ONE.SITTING. The bags under my eyes today were worth it

Really good! Could have had 5 stars but…
Format: Kindle
I thought this book was an easy and entertaining read. The MCs had some depth, and the angsty lead up to these two colliding was very well done. I love them together, I felt their chemistry, and this book could have had five stars if it wasn’t for the weirdly rushed and unbelievable way the ending was written. The back and forth was ridiculous and it seems she can’t change the way she has originally perceived him - as a rich, pompous jerk (despite only having his expensive kitchenware and childhood snark as her evidence). Then we are supposed to believe that out of no where, for no reason (apart from finding out he’s moving) she suddenly wants him back? And then despite how hurtful her words had been, he takes her back? Idk this ending was messy, and there didn’t seem to be enough written or enough plot for any of this to be believable. I won’t disregard the entire story because I didn’t like the ending, but I do wish it had been better.

Here's Three Reasons Why You Should Read This Book
Format: Hardcover
Actual rating: 4.5 stars I'm going to write this review a bit differently than I normally do, by telling you three things: 1. I am definitely reading more from Julie Buxbaum in the future. I was pleasantly surprised by how much I truly enjoyed this novel. There was so much to love about it, and while the underlying story wasn't revolutionary, I loved the unique way Julie Buxbaum navigated the topic of high school and feeling out of place. There was just something special about her writing style, as well as the characters she created. You will easily fall in love with the story and the characters, especially Jessie (our MC). I never got tired of reading this book, in fact, I actually didn't want to stop reading it! Julie Buxbaum managed to tell a story that was filled with sadness and depth, mixed with humor and fun. Yes, I figured out who S.N. was pretty early on (as I suspect most other readers will too), but this certainly didn't detract from the story in any way. In fact, it keeps you reading because you want to see how Jessie and S.N.'s story unfolds. 2. This book is incredibly real and raw, and that's the reason I loved it so much. “Just because you're strong doesn't mean you shouldn't ask for help sometimes. Remember that.”> Tell Me Three Things leaves you with a whole bunch of emotions all at once. The story instantly transports you back to when you were 16 and in high school (if you're an older reader like myself that is). And honestly, Julie Buxbaum just gets it. She captures exactly how it feels to be on the outside looking in, when you have multiple fears of not only the future but just how you're going to survive in this world where it seems like no one wants to be your friend. She captures just what it means when you hesitate being yourself because your insecure about who you are and you're not quite sure of anything or anyone. “He's more like me, I think: burdened with the realization that what goes on his mind is somehow different from what goes on everyone else's. Even those close to us. And how you can't think about that for too long, because that thought- the truth of your own isolation- is too much to bear.” Countless readers will be able to relate to Jessie because she is you and me and pretty much everyone trying to navigate the crazy world that is high school. Ultimately, Julie Buxbaum created very human characters that show what it means to be a teenager today. It also makes you wonder what if you had someone like S.N. to help you out during your experience. Would things have been different? I wish I had this book when I was 16 because this book would have probably been my lifeline in many ways. But the one excellent thing about this novel is that it reminds all of us to sometimes just let it all go, and let things happen the way they are supposed to. Trust the journey because you never know who might reach out and come into your life. 3. You need to read this book now! I high recommend adding this book to your TBR right away, and the reading it as soon as possible. There is so much to love about this book and I think everyone will have a different experience while reading. Some might not like it, but if you're like me, you'll find something to take away from Jessie's character. It was a quick-read that will appeal to many contemporary fans. This is a story of love, friendship, and finding yourself. But it is also a story of acceptance. Happy reading :)
