The modern stereo system

In my 66 Cuda I want two systems. The original AM/FM radio and the 6 x 9 front speaker in the dash. The second system will be two 6.5 in drivers in the trunk divider with 2 EMIT tweeters in the sail panels. Frequency range 50 Hz to 32kHz with crossovers. I would get a receiver with MOSFET power IC. I'm looking at Kenwood and Pioneer with preamp outputs and 4 x 22W RMS of power. Don't confuse size with quality. I like my music very clean and clear. Just the way it would sound if you were there. I use a 256 GB thumb drive to store my favorite, scrubbed music collected from over 50 years. 1,000+ songs take up only 5 GB of space. Maybe 50+ hours of all kinds of music without a repeat. These are not clipped MP3, files but audiophile lossless files. All digital, no 8 tracks, no cassettes, no CD's and no moving parts for playback. Just a thumb drive to plug in. If you want more power just use the rear outputs to an amplifier and extra speakers.
