[QUOTE="seanzy13, post: 7470640, member: 636287"] I'v had this system for quite some time now, but ever since I let the car sit and battery go dead I'v never been able to find the original settings I had that sounded great. The issue is bass. I can tune it to sound great on one song, but others require a change in settings again and some just never manage to sound like they used to. I should also note that the entirety of my music collection comes from an Ipod, and I realize the quality and settings of each audio file will differ. I try to always use very high bit rate rips, and get rid of bad quality ones I find. I do use Sound Check on the ipod. Now for the system: Head unit: Alpine CDA-9857, has standard bass and treb settings, BBE mode, sub level, etc. Sub Amp: Alpine V12 MRD-M1005 1000w RMS, digital gains, bass boost lvl, crossover, subsonic filter Sub: JL 13w6 in large ported enclosure. I also have a kenwood amp and some components up front who's brand name escape me atm, but that amps and speakers settings are easy enough to tune on my own. Now for settings: Amps bass boost is at 0, crossover 80hz, subsonic 15hz, Gain is 0.2 (one tick below highest possible gains). Heat unit settings: sub level 9, bass +2, treb -2, 80hz sub crossover, BBE mode 3. Anything else relevant please ask about. I'm not sure how to handle the BBE system on the HU first off. It makes music sound good, and bass hit harder, but only below volume level 22, past that it bypasses the sound processor. Should I tune my system to be as loud as I want it at vol 22 and keep BBE on, or shut it off and bypass it completely in favor of manual tuning? My gains on the amp seem rather high, but it seems that I need it this high to get the bass level that I desire, I'm not sure why. Perhaps quality of the RCA cables and voltage of the HU's output has something to do with this. I run at sub level 9/15 usually, I normally adjust this setting to suit the song playing. Perhaps my idea on how to set this is wrong. I basically set both to 50% and went from there until the bass was desirable, which for me seemed to be one tick below the highest possible gain setting. The issues I notice is uneven bass response. I know there wont be a prefect universal setting for all my songs, but I do recall the sound was alot more even when I first installed the system many years ago. [/QUOTE]
