So I have 3 amps I am considering. I'm really only interested in these 3. All 3 are close in price, footprint size and power. All three are rated 300watts @ 2ohms. So I have a 2018 Toyota Tundra, I am running the stock head unit with a Rockford DSR1 and a JBL Dsp4086 8 channel amp running everything including the sub for now. I am wanting more from the sub so I am getting a dedicated sub amp. The 3 I am looking at is the Kicker Key 500.1, AudioControl acm-1.300 and the Rockford Fosgate T500X1br. I want 1 of these amps because of the small footprint. I am running a 10in infinity 2 ohm sub (ref1000s) in a ported box behind the rear seat. Any input would be appreciated.
