Used Mirror acrylic bought from amazon https://www.amazon.com/gp/product/B01AWXNHT0/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
Since I can’t fabricate my own metal at my apartment due to the loud sound. I can use mirror acrylic, which reflects better than chrome. Major issues with tearing though, have to use hand drill (5/32″ bit) at low speed with your index finger, not too hard but time consuming. Will create an extra pot hole for a master volume/blower switch, dual volume control and a bass cut tone control and the output jack. Gonna have to space this out right, but I think it’s doable.
