Newbie - need help with a few questions

[The Straight Path]

Hello everybody!
Im completly new to this forum and a newbie.

I have decided to build a little speaker project and would like your help.

I have two bullhorns lying around and i thought I would make speakers out of them (i know the sound quality is crappy, it's just for fun) with a AUX cable.

Here are the following parts i'll be using;

2x Bullhorns - Pyle Pro PMP53IN 50w
Amplifier board TK2050 50W+50W TK2050 50W 50W Stereo Audio Power Amplifier Board Car Amplifier Module | eBay
or
2 Channels TPA3116 Digital Amplifier Assembled Board Kit?50W 50W | eBay
Battery - KDQ22 DC 12V 6800mAh Super Rechargeable Lithium ion Battery SCA 0650 | eBay

Can I use all these parts?
Do I need all of the parts?
What more do I need?

All answers are appreciated!🙂

I think this is wrong section. Should be in"parts". Maybe an admin can change that.
Thank you.

Seems to me if you want to use the bullhorns you don't need any other amplifier as these units have amplifiers in them. The only item I can see you needing is a cable to split your ipod outputs into two monos to plug into the bullhorn aux inputs to make it stereo.

Okey I get it. But what if I wanted to use an amplifier board? Would it work even though the bullhorns have their own?

And what about the bttery?
Is the battery going to work, or do I need another one?

Thanks for reply🙂
