I'm considering replacing the factory head unit in my 2011 Acura TL (non-NAV). I've been using the stock head unit with an Audio Control DQDX DSP and it just isn't cutting it. I thought of upgrading to a Helix or Audison DSP, but I feel like it would make more sense to fix the source of the problem (the head unit) rather than trying to correct the signal to make it sound better (and louder). My question is, what double DIN receivers are on the market that have some features found in external DSPs? Such as delay, phase, individual channel gain (including subwoofer), parametric EQ, etc. I listen to various genres of music, so a head unit with a dedicated subwoofer level knob would be nice, although I believe my amplifier came with a bass knob, so I could just use that. I'd also like to retain the steering wheel controls, and it is my understanding that PAC may make something for my vehicle? BTW, I am going for sound quality here and I'd be willing to spend up to $1,000 on the HU. I don't need or want navigation, backup camera, or video capability. If going with two single DIN devices would give me what I want, I'd consider that over a double DIN. Thanks.
