Very nice install... I attempted a similar install this weekend. New speakers in the front doors, replaced stock 8" sub with a new JL 8" W3 sub in the stock enclosure (dynamatted the entire enclosure and added polyfill), along with two new amplifiers for the doors and sub. Question, where did you tap the speaker lines for your line out converter? I tapped into the lines behind the stock head unit. Just curious as I'm having trouble with the sub amplifier. No sound output. Just curious if I am pulling from the wrong location... I am using the Hi-Level inputs on both amps. Ground, remote and power to the amp all good. Any help would be appreciated. Thanks.
