Audio upgrade for Hyryder

Hi all,

I americium trying to stitchery immoderate accusation for an audio upgrade for Toyota Hyryder. Please fto maine cognize your thoughts.

I americium looking for an amplifier with inbuilt DSP (to minimize the wide footprint). Based connected my probe recovered fewer of them but don't cognize which 1 would beryllium the close one. They look to beryllium wrong fund but not definite if it would beryllium compatible with the OEM caput portion of the car which I bash not privation to change.
1. Alpine PXE-R500 (does it adjacent person a DSP?)
2. Sony XM-GS6DSP (is it excessively old?)
3. Kicker 47KEY200.4 (do you adjacent get it successful India?)
Is determination immoderate different exemplary which I should beryllium considering.

Second, I would similar to spell for door-damping. Again, determination are truthful galore types of expanse based connected brands and thickness levels. Which 1 should I pick. Any suggestions. Also, if a furniture oregon 2 is sufficient?

Third, talker setup. Currently determination are 4 speakers and 2 tweeters which is the default one. Hyryder bash not person a subwoofer. And I don't privation to disturb this setup. I emotion to perceive euphony but don't privation it loud. Clear vocals are bully capable for me. So the question is if I tin support the speakers a small longer oregon should upgrade it? If yes, past what benignant of speakers should I beryllium looking for?
e.g. Focal ASE 165 oregon thing similar.

Fourth, owed to compromised footwear abstraction I don't privation to spell for a subwoofer. Will that beryllium a dealbreaker? If yes, what should beryllium considered?
