I have a 03 4.4i with reg. stereo non dsp, with 6 cd changer. I installed everything, power wiring etc. Have a 2 channel amp.

Tapped into the wires from 11 and 12, and 5 and 6... hooked them into the high low converter, which then plugs into the amp via rca cables. I tried only pluggin just the 11 and 12 and just 5 and 6... but no luck. I am attached those wires to a cut rca cable. so one end can connect to the filter. But no sound, however my stock speakers sound hella lot better! lol.. also, keeps blowing the cd changer fuse. What am i doing wrong?
