I have a small problem, amp has 4cm fan but I can hear it's rpm from the speakers. When I stop the fan sound is clean. Should I remove the fan?
Here's project logs of my previous builds:

Do you think that two of these would be a good choice for a downsized boombox using the ta2020 AMP-6?

Thank You for your throughts,

Hello Drakmin.
I've followed your project for a while, since we are building our own (although more Boominator-style), but the finish of your megablaster looks like it will be on a completely different level.
Can I ask you what you think it will cost for the plexi-glass laser cutting? I would really like to have that on our blaster, but I'm affraid it will cost too much.

Hi, I think the acryl will cost around 100 euros. Here's the measuring of the box:

LiPo battery i got from hobbyking is dead. They sold it to me with too low voltage and it cannot be charged. Thank you!
Other things have progressed:
Here's a small mask I made to hide the wood parts. It's not cool if you see wood from the edges of the led scanner:

Yes, the problem is that batteries have 30 days quarantee and I didn't realize I should have tested it instantly when I got it. I just kept the battery in it's package and tested it now that I would have started using it.
Anyway the lipo was dead already when I got it, 18,5V (5s) lipo shouldn't drop to 7V voltage in one month. I won't get refund nor new battery, but this drawback won't stop me. Just 0 points to hobbyking on this one.

as far as i know, any rechargeble battery comes from the factory about 30% charged, not 100% charged.
thats why they asked you to test it when you bought it
a deep discharged to a recharegble battery for long period is harmful and sometimes deadly.
each kind of battery changes the way it should be treated, it is well recomended to read some information about deep dischareged, according to the battery type, of course.
all of these are recommendations, only facts that i know and i hope that someone here will proffesionly talk about it (i dont have any proffesion information to give you)
good luck, and dont let some obstacles to stop you. it is easy to see that it is very serios project and i am waiting to see the final results.

Thanks! Hehe this ain't so serious project but something to keep me entertained on my spare time! I've chosen to replace the dead 18V lipo with 2 x 9,6V 4100mah nimh batteries since I can get those from here where I live. I think 4ah is enough since with ~20V I get about 1x40w peak power from the amp. (and im not listening to square wave anyway)
Hopefully I'll post a lot of progress during next week.

Finally got new batteries. 2x 7,2V 4500mah nimhs. Blaster should be finished soon.

Sound is great for a blaster. I added 6db/oct highpass filter @ 70hz. A bit more spl.
