Finally got the install done. Lots of waiting on a subwoofer that was out of production, etc...
The JBL rear speakers were also an easy drop in. Tweeters in the pillars required popping out the original heat staked mounts and using one of the mounts included in the JBL box (lots of options, I made one work). The JBLs stick out like bug eyes, but could return to original if I want. Mounted the JBL crossover in the dash, behind the triangle piece on either side of the dash, but tucked to the inside. Cut into the harness of the PAC 1416A to get speaker input to the doors, dropped the wires from the new tweeters down to the crossover, and ran wires from the new amp along under the doorsills.
The JBL amp was too big for behind the driver's seat, so it found a home in the trunk (even less space than before, ugh!).
"Settled" on a JL Audio 10" shallow sub. Lots of tweaks on the factory box from Charlie to make it fit, plus a 3/4" spacer on the inside of the cabin. Removed the factory grill ('09 had it even without Monsoon). the spacer fits that spot.
Don't tell the teenage me, but 2,000 watts in that tiny car is almost too much. The 10" JL hits hard. Angry even. the JBL speakers are crisp. The JBL amp was easy to set the gain and sounds awesome with the factory head unit. My ears are ringing tonight.
