I recently aquired a 2000 Wj with a infinity 10 disc, 6 spkr, & factory amp, i noticed the front door spkrs were inop so i removed door panel & there is Alpine 3-way coaxils 6x9 in there. next i cranked the volume way up & i can barely here music with my ear to the spkr! so i tried another spkr same result, now im thinking its the amp so im researching & checking wiring schematics & i came across a post on the internet which came from this forum by user 94zj318 im new & i dont know how to contact him or her so here i am! they stated that the infinity system with factory amp on 99 - 04 Wj's only supplies low frequency bass to the front door spkrs but without the factory spkrs i have no way to check for sure or if someone knew of a replacement spkr i think they are just paper coned woofers! anybody got any ideas?
