2019 Honda Fit EX audio system installation options
I just brought a 2019 Honda Fit EX. Love the car. I've wanted one for a long time but I brought a Nissan Versa Note instead but it got totaled so now I have the Honda Fit but I want to install a aftermarket audio system in it and I want to get some ideas of what can be done.
The Honda Fit has the factory infortainment system but its pretty lame with no HD Radio or high definition music file playing capability. It does have Apple CarPay but I want MORE. The Door speakers are 'Ok' for the average listener but for an audiophile like myself they just don't cut it. I'm looking to install some Hertz Mille Pro Series MPX-1653 6.5 speakers in the front doors and come Hertz Coaxials in the back door powered by a 5 channel amp for a less complicated installation with a 10" JL Audio subwoofer in the back. I need to know this
1. To use the factory Head Unit I'll need to use a Line Output Converter like this one
LC5i PRO 5 CHANNEL LINE OUT CONVERTER WITH ACCUBASS
to connect it to a external amp so I can keep the backup and Lane watch cameras but can an aftermarket head unit do the same thing and if so what make? Pioneer, Kenwood etc.
2. Where would be a good location for mounting an external amplifier?
3. The 2019 Honda Fit EX has a 105 amp alternator. How much wattage can I install with an external amp that won't overpower the electical system?
4. Can I replace the factory alternator with a High output alternator like this one
220A High Output Alternator for Honda Fit, 2017 - 2020 1.5L L4
for higher wattage amps without damaging the rest of the electrical systems, vehicles computers etc.
5. I was thinking of replacing the 151r battery with a larger 51r AGM battery, any issues there?
If you installed any aftermarket car audio componnets and/or systems in the 3rd Gen Honda Fit I'd like to know what you did and how your installation went. Pictures would be nice as well.
