I got a good deal on 4 of these: https://www.bestbuy.com/site/jbl-gx-...?skuId=6283672
and a JBL low profile subwoofer.

I bought these for a ford transit van conversion that I'm going to start soon. I'm not going to listen to these super loud. What would be a good affordable amplifier (preferable class d so that it does not use too much of my battery) running on 12v?

And what could I use for Bluetooth or aux connection from my laptop/phone?
