Review: Produto bom uso bastante
Review: 9-17-25 I give this very tiny lil amp 5 stars so far!! I actually am using it passed thru my Fosgate RX500D amp....It is clean no humming no no hissing in the 2 RF P3 speakers I have in my back dash. I totally played myself by purchasing the Boss CE102 to drive the P3s which was an absolute disaster...that amp is so terrible it pushed interference thru my P3s and my 12" Kicker sub...I thought it was my grounds, RCAs, etc until I started process of elimination. SD EVO is clean and crisp and very small so concealing it is very easy...my only gripe is the speaker terminals are right next to the power terminals but they obviously did some expert engineering...again the lil thing sounds clean.
