Please help me plan stereo upgrade for new car...

  1. Default Please help me plan stereo upgrade for new car...

    Ok so I'm taking delivery on a 2013 328i (withOUT Harmon Kardon stereo option, I wasn't impressed) , and want to do the following to the stereo... pretty simple actually:

    - Keep stock head unit

    - 3-way passive speakers in the front doors. Could be total DIY with custom crossovers, not afraid of this. I've done tons of DIY home audio, so no big deal... But also not opposed to a pre-made 3-way... Tweets and mids up high, woofers down low... LOVE the Dayton RS Drivers... Maybe 6"W + 3"M + some nice fabric dome that fits in the sails.

    - Simple 2-ways in the rear doors for some rear fill, probably just coax, mostly just for when my son is back there... will likely be off when just front seat passengers.

    - Small-ish sub in the trunk, maybe a sealed 10"

    - Single chunky 5-channel amp powers all... sub runs off of 5th channel... less than super awesome, but keeps it simple... This is what I've done on a few cars now, works well.

    - Damplifier in doors, not gonna go too crazy since sound deadening in stock car is already quite good (so I've heard)

    - No eq or anything fancy, which is part of why DIY crossovers are appealing... I can keep the crossovers in the trunk, for easy access in case tweaking of component values is needed.

    - Whole shebang wants to be pretty stealthy, keep bone stock appearance

    So...

    Can anyone point me to some killer DIY 3-ways that would work well in the front doors? or maybe some pre-mades?

    Wanna help me ground-up the 3-ways? Could be fun, but real testing will be a pain, since I'll be driving this thing every day...tearing the doors apart multiple times ain't an option.

    Is this car a nightmare? Remember I won't be upgrading the head unit, if this helps...

    Yes I've also posted this on DIYMA

    Other thoughts?

    Thanks!!!

    You could get the JBL MS-8, it has an 8ch amplifier built in, and does all the processing, but most ppl, from what I've read about it on DIYMA, use the "auto-tune" feature as a base and work from there.

    Also there's the JL audio and Rockford doo-hickies that allow you to use your stock head unit.

    Alot of people are using the miniDSP in they're vehicles, and you can get up to 4 channels per side (T, M, W, S) or (T, M, W, Rear) and add subs... You could use those uber-tiny new JL audio amps for that.

    What 5-channel amplifier are you looking into using? Make sure the sub channel has 500W or so, becuase if they're mounted in the truck and that BMW is as soundproof as one would assume, I've driven a newer 5-series and it was almost dead silent inside, you'll need quite a bit of power on the subs.

    You can do a little research on DIYMA as to what can fit in the doors, I'm sure someone has worked on one or a previous year's model, there's alot of pro installers on there.

    Good luck and Congrats on the new ride!

    Thank grey

    I'll definitely check out everything you mentioned.

    Not looking to go active, as I don't want to deal with all of the extra amp channels involved... running power to all of them etc... dsp setup you mentioned means going active right?

    Rockford Fosgate makes a simple 5-channel that should get it done, I think 300w from 5th channel, I forget... using one in my '04 Mazda 6 currently, very happy with it... with an efficient vented sub it should be enough

    "Not going too crazy" is the theme here

    Ha! Wow do I have a lot to show you...

    No I don't think an 8" would fit well without serious mods.

    I'll post a link to a very serious 6.5" install I did.

    Instead of doing three ways (sounds very time consuming and custom), maybe you could check with the BMW forums and see if the stock unit has hidden sub out on it. Or, just check the BMW accessories options and see if a sub is available. If it is, then the wiring should already be in place.

    Does the stock unit put out enough power to drive large woofers?
