Today was about installing the JL XD300/1 in the trunk. I stuffed it on the right side of the trunk under the storage tray. It fit in there with about 1 inch of clearance. With it being right next to a cabin vent, I'm thinking it should get adequate ventilation.
I ran 4 gauge wire to the battery lug. JL says you can use 8 gauge-- F that...
One thing I noticed on the Match amp; while it's powered through the OEM wiring harness, you can also hook up 8 gauge wire directly to the amp. The manual says that if you have any system noise you should try that. I don't have any noise as of yet, but I'll keep that in mind.
So now I'm just waiting on the Musicar sub enclosure; should be here next week. The Morel Hybrid 402's will be arriving at the same time.
