McIntosh Sub replacement

21 posts in this topic

Car - 2006 Subaru Legacy 3.0R-B WAGON with McIntosh factory 12 speaker system. 

So I have the standard issue that the factory McIntosh sub has split (I got it repaired at Axent Audio in Auckland but within a few weeks it had split in another place) so I am keen to replace it.
 

I have fitted a blue-tooth kit to the factory McIntosh head unit as I quite like the factory set up, and basically couldn't justify the massive effort and price in changing out the head unit with it being interconnected with the dual zone climate a/c unit.
I have found a replacement Sub which is a KENWOOD EXCELON KFC-XW800F SHALLOW-MOUNT 8″ 4-OHM SUBWOOFER from Driving Sound on Dominion Road - kenwood-excelon-kfc-xw800f-shallow-mount-8-4-ohm-subwoofer. The McIntosh is 4 ohm and so is the Kenwood unit I have found.

 

I like my music but wouldn't say I particularly crank it all that much, thus I am not keen to go and "start again" with the whole system in order to get some that is next level. 

I want to know if the Kenwood unit will work as a straight replacement and will work with the factory amp (under passenger seat) as I have read some forums which make me think it won't, but the people at Driving Sound seem to think it will.

 

The next issue is fitting it into the back right corner of my wagon, as although the unit isn't any deeper it is slightly wider overall (behind the front of the sub) so the bracket space needs to be increased. I could pay another $200 bucks and get  box for it but then I loose some boot space the factory look which is quite important to me. 

As I am new to Auckland, I wondered if there is an automotive fabricator/chippie or someone else handy who I should/could get to do it. I just need some assistance in carving out some more space in that back right corner and creating a slot for the new sub. I am happy to pay the money to get it done properly as opposed to stuffing it up myself! A quick Google landed me on "Stu's Trim and Sound in Manukau. I am sure they could do it easily enough - any other suggestions or comments on the above in terms of things I have overlooked?!

cheers. Mark

How'd you get on with this Mark? I'm in a similar situation with my new 04 outback and I'm reluctant to strip out the old system as I did with my old subie (took a day). Also, what bluetooth system did you install? Cheers - Peter

Ummm, I'll need to find it but there is a discussion somewhere else a about  sub that is direct swap.

 

I have a "Yatour BTA" in my BP's that have a Mcintosh system that I got on Aliexpress. Chinese unit that is half the price of an AnyCar unit and works great.

I ended up doing a straight swap for a new sub in the boot as the factory one kept tearing. I used Rapid Radio just off K Road and they installed it for me while I waited. Seems to be working fine and I've had it for the last 4-5 months. I didn't end up getting the one I quoted in my original post, but another one that was slightly cheaper that they had in stock. If you drop in and see them they will be able to show you a couple of options. Zero Flex 8" woofer.

Foe the bluetooth system, get in touch with a guy called Lance - he is based in West Auckland and has a mobile service. 021526 238. Plus he has a legacy wagon himself so you know he knows what he is doing and can see it in action before he does the work. Works with my music/spotify and can answer and end calls with my steering wheel buttons. Its great!

Was this the one you bought?

Seems to be the only one on Aliexpress with the correct plug?

Appreciate all your responses thank you. Yes, looks like the Bluetooth hijacks the clarion bus interface since they made them for McIntosh.

I've picked up a shallow mount pioneer sub for the gap. Have been considering a high-low level converter for a new sub amp, but found my front speakers are shot. Replacing those hits issues on impedance (4ohm vs 8) and potential crossover issues if I drop in components and the stock amp is also filtering the signal before the crossovers. I'm going to have a crack at completely redoing the system if anyone is interested in the details, tapping into stock speaker wiring etc.

We love pictures showing progress here :) Sounds like you've got some fun on your hands!

Hi team! Sorry to bump the thread but I too have the McIntosh speaker system in my 07 LGT and it’s done the exact same thing. I can’t live without having some element of bass as the speakers sound terrible without a sub.

 

Can anyone please recommend me if a factory replacement sub which I can take out and put in or let me know if it’s possible to buy a seperate small sub and plug it into the factory amp (can find any inputs) 

 

Orrrrr if I can just get a new sub/amp and some how wire it to the Mcintosh head unit? 

 

Thankyouuuu!!!

I originally wired in an aftermarket amp and sub using a line level converter connected to the post amp wiring at the old sub end. 

Worked fine for the minimal amount of effort needed.

There’s a few options that fit in the stock location running off the stock amp.

I'm still yet to do mine, but I've picked up a shallow mount pioneer sub from trademe (120w nom by memory) that should slot in. haven't tried on the original amp for now, as i'll give it a better source later. Andy above using a Hi-Lo converter is an easy solution! Some older amps have high level inputs too.

 

I'm going to strip the rest, as confirmed the front speaker woofers have lost their foam surround and don't want to dabble with fixing/replacing those drivers. At the recent auto sound&security, they had a single dim headunit mounted into the McIntosh headunit area quite nicely so I'm going to try this.

Thanks guys!

 

I may be retarded but ive has a look on TradeMe to no avail. Any cheap/reliable websites anyone can recommend?

im guessing this would be sweet though? :) 

 

The only reason i son I ask is the macintosh one in swapping for days max 70w 4Ohm so I don’t want to damage the amp. Complete noob here sorry guys, maybe the amp will only provide upto a certain amount (70w) to the new sub anyway etc

Yeah if you're keeping the macintosh amp then try pair a sub with similar rms impedance. Second issue with that sub is how far that spiky dust cap may sit out (if any). You could always rip it off.

@Cookasaurus would you say I’m better off to buy a new amp to replace the Mcintosh one at the same time as the sub then? 

 

Ive just read that the original poster installed the Zeroflex 8” subwoofer too and didn’t have problems so I’ll go with that if you all think it will be sweet with the stock amp?

 

Finding an 8” sub which is only 70w max will be quite hard! Haha.

Adding a question to this - 

Would an underseat sub be an alternative, if you're not able to find a suitable 6x9 sub?

 

Not looking for LOTS of bass. Just enough so my sound system doesn't sound so flat.

 Hi @csrgm1915 yep still very happy with my option from Rapid Radio, cheap and easy replacement and gives me enough performance my my relatively basic needs, more punchy than the original sub too.

I toyed with this idea too but wasn’t sure about hooking it up to my McIntosh headunit etc as the amp for the factory is pretty weak.

 

in the end I just removed the broken McIntosh sub and went to town with epoxy around the outside of the torn speaker and put it back in, sounds pretty good for me! Haha

I’m looking at getting the Zeroflex Sub for my Legacy. Is everyone pretty happy with it?

 

If anyone is looking for replacement speakers for the front I would highly recommend the 6” Kevlar cone woofers from surplustronics.co.nz (link below). BUT BE WARNED!! It’s an absolute mission to get them installed because the magnet is huge so you’ll need spacers, remove some of the plastic ribs on the inside of the door card, some self tapping screws, an impact driver or drill with hex bits and a bit of massaging/good placement so it doesn’t hit the window when you wind it down. They are awesome speakers though so if you’re willing to put in the effort then it’s worth it! I also bought an 8” Kevlar cone woofer to replace the sub but I didn’t realise the sub was only 4ohms so the new 8” 8ohm woofer is only about half as loud as the stock one :’) hence why I’m looking at the Zeroflex.

      Hi all, I've been collecting parts for a single turbo conversion I was going to do to my 98 bg5 GTB ej206 manual. (yeah weird, and wrong CR as it runs manual ecu, yet has reliably run for the two years I've owned it) but then I scored an 02 rev d bh5 yesterday with a blown primary. So now it seems sensible to put all single turbo stuff into the rev d as my bg5 has nothing wrong with it (yet). I understand it's a bit of a different process, but I think I have most of what I'll need. I have a td06 20g, full length tuned headers (slip joint type), 3" down pipe, fmic setup, greddy emange ultimate piggy back ecu (just gonna buy a harness, CBF with repin or splice), tial 44mm external wastegate, blitz bov. I also have half a WRX in parts and a spare motor to scavenge parts from. So what I want to know at this point is if anyone has used the factory ecu in the rev d to go single? I believe they are tunable? And other than the wiring and different intake, is there a hell of a lot of difference in the actual physical process of swapping everything over? I read the single turbo thread, am I able to largely follow that? Or is it a completely different game?

      Wondering if anyone can help me out with this.. Im looking to put Ver7 Sti wagon rear seats into my BH5 legacy wagon. Any and all info regarding this would be very appreciated. I have already started the swap and am soon realizing the trouble ive gotten myself into .. Ive done a full 6 speed driveline swap into the legacy already and have the front ver 7 seats installed and really want to fit the ver 7 wagon seats in to match!

      Hey Guys,

      I have been having a mess around with our Legacy GTB trying to get a few pops and crackles on decel. I'll start with the car.

      We have a 2003 Legacy GTB with an EJ20Y, so it has the bigger TD04 Turbo, car has a gutted cat in the downpipe but the secondary cat is till in tact but i think its on its way out, the whole bottom of the cat is covered in white stuff and you can get a bit of an eggy smell sometimes, so that could be an issue. I have been playing around with the "Base Timing B" maps as this is the map most people adjust to get pops and crackles. I have adjusted between 2000rpm and 5000rpm to -12 degrees but the car still won't pop and crackle, is this because of the secondary cat or another reason? I would have thought even with the secondary cat you would still be able to hear it try to pop. The WRX's and STI's seem to have an Overrun table which our legacy doesn't have, also tables called "base timing b (in gear)"  A few questions come to mind.

      1. When does the car actually use "Base timing b" and "Base timing a", 
      2. Do i need to add fuel at the points where the timing is retarded.
      3. Does the Legacy cut fuel on decel? 
      4. Why wont you pop  

      If anyone has any info at all that would be great, 
      Cheers
