I had the front door panels off, so I completed the first step in my stereo upgrade. Honestly kind of shocked by how well it worked as is.

I’m running Morel MDT-12 tweeters, with Dayton RS150p-4 mids.

With some EQ tweaks on the AVIN (bass boost, really, also front fade), it sounds way better than anything has a right to on the stock amp. I’ll still be swapping in an amplifier and a sub, but if you need an easy and simple upgrade, I highly recommend this. It also highlights how shockingly garbage the stock speakers are.
