Replacing speakers in the M

[SwissCheeseHead]

Audiocontrol would definitely help if you want precise control over the EQ, crossover, timing, etc. but is definitely not required. If you want to do a "crossover" without audiocontrol, you could turn down the bass on the factory HU and turn up the gain on the amp, However, if you did this you would be putting more strain on the amp over long periods of time than it probably should have during normal duty. Also, you would be out of the mid range.

What I would do is get the sub and amp installed, turn down the amp (so there's no sound from the sub) adjust the treble and bass from the factory HU to cover the High and Mid range, then once you're satisfied with that, adjust the amp to get the amount of bass you want.

JL makes good stuff. I've always used Alpine myself. Good performance but a little less spendy.

Gotcha. Seems easy enough.

And yeah, I had that sub and an alpine amp last time I had a system.

I think it would be neat if someone replaced the OEM sub with an aftermarket sub, but then built a sealed enclosure that was mounted in the stock location. You would have to reinforce the sheet metal to support the weight but I can't imagine it would be *too* difficult. Carpet up the hanging box or build a faux fascia (front facing side and bottom side) on the box to extend towards the sides of the trunk to make it look really clean.

Might be worth the project some day

Funny, I was thinking the same thing last night when I was responding to this thread.

I picked this up, along with the control knob.

Since I'm initially adding a subwoofer. I have to find a lot of time to perform a system overhaul. I'm sending the sub off to get it repaired tomorrow. Once I get the sub back, I'll have the box built for it. Then it will be installed. I just need some real low frequencies. Not a fan of all this speakers, 16 speakers should sound a lot better than this.

So, using Swiss' guide...let me see if I got this right.

Stock amp > hacked RCA cable/wire > The LC2i > Aftermarket Amp (with the control knob running into the interior console area?) > Sub

Right?

Cool. Sounds like a plan.

[SwissCheeseHead]

Are you doing this soon? Let us know how everything turns out.

[Ilya]

Not soon soon, but probably before the spring time kicks in. Gotta have dem beats with the windows down, nawwhatimsayin? (obviously, for the days when I'm not living life on two wheels )

Since I'm in that Cold Windy City, it really will depend on the weather.

[SwissCheeseHead]

lol. Yeah, winter does put a damper on things. I won't be doing anything while it's still less than 32F out. Ilya, let me know for sure if my write-up works for you.

[Ilya]

Will do.

[Darthswan]

Bumping this back up. Has anyone replaced anything yet?

[Ilya]

Nah, I never got around to it. Still plan to...some day lol.

[Darthswan]

Bumping this thread again. Life has been busy, but I have ran the power line and installed the sub. I'm now looking at adding another amp for the front door speakers. Something I miss, is riding down the expressway, windows down, and hearing all of the words. The factory system doesn't do it fully. So I figured if I can replace the front door speakers, all six of them, that would accomplish the mission. I'm going to do this in stages. I have an old Rockford I'm looking at getting repaired, but in the meantime I will use the Infinity amp for those.

I remember seeing a thread that had the door depth dimensions, but I have to find it. 3 way component speakers are few in number. Still researching this one out. I know the front door has 6x9 in them, but I would replace with a 6.5.

It's been a couple of years, so I was bringing this back to life.

[Ilya]

Yeah I never got around to my system either and doubt I will. I haven't even got coilovers yet...so sad...

[mrnix]

count me in those interested to see how this turns out. Due to the complexity of the bose setup, I will probably just end up adding a 10 in sub in a small box in the trunk. I had a 15w6 in a fiberglass box in the trunk of my G, but it gobbled up more space than I care to concede in the M.

[Darthswan]

My biggest challenge now is finding the right speakers to replace the 6 speakers in the front doors. I was able to lobby the wife for an increase in my budget, and the lobby won. Since i've already taped into the line with the Audiocontrol, I can add another amp to it, and power the doors.

Anyone have ideas on good ones for the doors.

I've seen JL, Focal, MB Quarts, so far. I have to listen to them.

[mrnix]

Darth, how did your 15W6 sound? That's what I had in my G, but I can't concede that much trunk space in this guy, and will probably do a Dayton HO 10 in a .9 ft2 ported box, if I can make it work.

I have the 10 speaker setup, and I'd like to replace those, but it's unlikely to be worth the enormous amount of trouble required to rewire the whole system and likely lose some of the built-in functionality. I'm curious what sort of progress/results did others end up with in your speaker replacement endeavors?

[Darthswan]

It sounds great. I missed my subs. I've grown so now I just have one. Surprised i didn't loose as much space as expected. Go for it it's worth it.

16 speakers suck. I figured I start with the front doors and see what it does to the soundstage. I have to find some 3 way components that don't break the bank.

[Nachy]

Hey guys im pretty new to the forum world. I have a 2011 M37S Where do I start so I(my installer) initially tried to bypass the boss system by tapping into 1 of the lines on the factory amp to add 2 amps (sub, speakers) blew the radio. Bad idea hindsight. So had no choice but to go through factory. I'm running comp6.5 front and coax6.5 back, brand= powerbass. I know I know but they were free. Didn't sound so well, got some echoing so I decided to run a processor. audio control dq-61 sounded alot better but clarity was lacking at higher volumes and still echoing Any ideas? speaker amp Arc Audio KS300.4...sub amp Kicker dx 1000.1 sub kicker L7 12"

I tapped into the signal before it went into the amplifier. No radio issues. I did not clip or disconnect the rear noise reduction, so when the LC2 is turned up you get a hum. I am looking at replacing the part of the front stage(doors) with 3 ways.

What type of components are you running. 2 way or 3 way?

I got some wiring done over the weekend, grabbed the rear door and sub wires to tap into going to my AudioControl LC7, so it will sum the signals. I am curious where you grabbed the stock amp inputs? I didn't look too hard, but all I saw was the output wires. the LC7 will sum the signals, so I won't get stuck with too low of a crossover point if I don't like what the stock sub is getting. I'm hoping the rear doors aren't crossed over higher than I need though - I'm reconsidering my decision.

[Darthswan]

I ended up replacing the Sub, now i'm going to have to cut the rear noise cancelling. When the sub wants to go deep and hard, it is like it is prevented from doing it. Then the hum is worse. I clipping it will be

Has anyone try to add the factory seat speakers on the m37 ?

I'm fairly certain that would be significantly more trouble than it's worth. You'd have to find something to properly process the signal to the speakers so they sound as intended - can't just tap into the factory amp, nor do I expect you can add an aftermarket amp and get the right surround sound, since the factory stereo without the speakers won't have the same surround processing. On top of that, you'll have to extract and dismantle the seats to wire them, and then cut the applicable portion of the leather to get the speakers in.

[Darthswan]

Bumping this again.

Have a question..

What's the mounting depth of the of the front and rear door speakers?

Finally have the time to get back around to this. Since I last posted, I added a sub. Sub blew got a new sub, so now i'm just going to do everything. Got the green light from my queen, so we are good.

Looking at replacing the front and rear doors with components. I'm not going to replace the speakers in the seats or the 3.5 in the door. Next weekend, I will build a new box for my sub, and hopefully the amp will have been shipped by then.
