I want to create a portable boom box. The amp i want to run needs 36 volts. But I also want to have a bluetooth and a usb out on the box that both need 12v.
What is the best way to get 36 volts to the amp but 12v to the bluetooth and usb out?
Should I use 3 12v batteries in series so i have 36 volts? Or should I use 1 12v battery and use a voltage step up for the amp? Will using a voltage step up add any undesirable noise to the sound?

300 watt is A LOT. You can create a huge amount of sound with <50 watt. Can you share some more details of your project?
In this situation I would choose for 3 batteries since you have to pull a huge amount of current on 12v to create enough amperes on the 36v line. Then use a step down module to get your 12v rail.

I have two kicker 6x9s CS Series | KICKER, CSS69 that are almost brand new and I want to put them to use. They have an RMS of 150 each. I want to build a boom box that can get as loud as possible without distortion with these speakers. I will be bringing it dirt bike riding and to truck races where it is loud, and also using it for parties in the desert after.
I am new to this project, should I use the kicker 6x9s or are they a waste?

They are not suited for this purpose. Sell them or put them in your car 🙂. Skim the boominator thread and you will gain a lot of knowledge. What's your budget, exact goals and other desires?
Lutkeveld, thank you for your replies. I want to create two portable boom boxes out of two everyday household items. I want to create these and see if there is a demand for them with the crowd I hang out with to see if I could create a (very) small business out of it. I currently have a small business/re-sellers license, so I could probably get a discount on the components needed if I buy them in bulk (which I would be willing to after the initial test).
So, I want to make the loudest, great sounding radio I can with the dimensions I have to work with because of what they will be put in. I would like to stay under $150 in parts for the smaller radio and under $250 in parts for the larger radio. I only need sound coming from one side of the radio, not front and back.
My box dimensions are:
1) 17"long x 10" high x 6" wide.
2) 12"long x 8.5" high x 7" wide.
I want OVERKILL and my ears to bleed 🙂 , as long as the music sounds great. I don't care how heavy they are.
I also need a 3.5mm input and bluetoogh connectivity.
With my dimensions, what would you recommend?

Go read the Boominator thread. It'll give you a lot of pointers on what is actually physically possible.
Saturnus, it seems like many of the images from the Boominator thread are broken. Can you share some images of the set up?
Yeah, so much for imageshacks and other cloud services assurance that photos will be saved indefinitely. Took just 3 year before the first ones were corrupted. Now 7 years after first posting they're all but missing.
Anyways, a vast number of people from across the globe have built Boominators. Some have been kind enough to post image on the facebook page too. Others can be found doing a google image search. I sadly don't have the original photos anymore (HDD crash many years ago).

Saturnus,
I have been reading pages of the Boominator thread, but have not come across a parts list. Do you happen to have a parts list you can share that will tell me all the pars necessary in one location?
