I have the base audio, wanted to try something cheap for better sound. So installed the kenwood 6x9 +3.5 component set and JBL 3 ways in rear 2.3ohm. Found a Infinity dsp amp on ebay, factory refurbished for $79. At work last night, I used a anc ch01 harness, connected the wires from radio into the Infinity dsp amp and the speaker wires out to speakers. Used the yellow power wire and ground on the anc ch01 harness. The Infinity amp is 15amp, the anc in truck is 25amp so should be fine. Plugged into truck and worked, now tuning the system, is done on laptop through USB. In future I can use the infinity amp as a dsp for my entire system and it becomes a line driver, the speaker level inputs did not require resistors. It's louder now than my old 13 Ram with alpine system and the alpine system i replaced all doors and dash with Infinity speakers. If I add a subwoofer I would just need to run power and ground and connect to the rca's on the dsp amp or if i don't want to use the 35 watts per channel from the amp, can add amps and use the dsp from the infinity. Total invested right now, Kenwood 6x9+3.5 components, $200, JBL 3 way back doors $85, anc ch01 $15, infinity dsp 4425 $79 ebay, $30 for some sheets of butyl sound deadening and $20 for some self stick closed cell foam to keep door rattle down. Less than $450. Amp seems good enough for me, getting old and need to keep my hearing. Was literally plug and play, all wiring was done inside and just went out and plugged the 2 connectors in from anc in and anc out
