Car Audio Questions - 64 Dart 270

Like cars, the budget determines how good it can sound. I use my smart phone as the source and wifi an online music service like Tidal. The lowest quality sound they put out is CD quality.

I do have a double DIN head unit to control everything, which feeds into a Zapco DSP-VI II processor then into 4 high-end Z-AP Zappco amps. One for the pair of Legatia X1 tweeters (A-pillars), 2 for the 4 Legatia X6 7.1" midrange/midbass drivers(doors) and one for two 12" subs under the rear seat in a custom tuned enclosure.

The DSP has time delay and actively crosses over all the speakers, so the bass sounds like there is a drum set in my dash. It's stunningly clear even at high volume.

At this level, it's all about component selection and installation quality. Good sound cost money, sir. How good do you want it to sound?


I’m looking at JL 6*9 3-Way Speakers for the two speakers on the package tray, and the speaker in the dash.

I’ve found kickpanels on eBay that fit 5 1/4” speakers such as these JL C2’s or these JL C5’s, and kickpanels from Retrosound that fit 4*6 speakers like these Rockfords.

Beyond that, I know I want a sub to get good bass, so I’m thinking a sealed 12” or 2 placed behind the backseat in the trunk. Not sure what sub though. I’m also unsure about what a good amp(s) and crossovers to run to make sure it all sounds best.

Any advice appreciated.
