Toyota Tundra audio parts to beat girlfriend's Harman Kardon in her Volvo.

I need help guys! My girlfriend has a premium Harman Kardon audio system in her car. We both love it. She is teasing me about my Tundra's crappy stock sound system all the time. Yes, it is not amazing for sure. I also LOVE clear real sounding music, opera, classical music and hip hop.

My plan is to build an amazing sound system in my Tundra which equals or sounds better than the all around rich, detailed sound of her Volvo.

So HELP ME!!! I am desperate.

My Tundra is a non JBL system, no amplifier and no subwoofer. It has 6 speakers. (2 front, 2 rear and 2 on the instrument panel. no tweeters. )

I would like to replace the stock radio. (Android audio wouldbe great and reverse camera input, the rest I don't care. I just wan to have crystal clear sound...)

Budget: under $1000 or maybe $1500? I am willing to buy used amplifiers, speakers, etc!

Please help a Toyota owner to impress his girlfriend!!!!
 
Buy a Kenwood head unit from their excelon line, use a decent amp, and a well reviewed 2 way (6.5/tweeters) with dedicated crossovers, in the stock speaker locations. Spend a lot of time reinforcing, sealing the doors, and you’ll be fine.
Those head units have a decent eq, and timing adjustments, which helps a lot.
