E60 under seat woofer

[Dav_C]

I saw one item when open up the lining at the boot, looks like an amplifier.

Then I saw shallow woofer speaker under the car seat, not sure whether powered by the amp behind.

Has anyone done improvement on these items to improve the bass? I don't want to sacrifice boot space.

Re: E60 under seat woofer

hahahaha.... this is the start of a slippery slope...
i supposed easiest way to improve bass is to get an amp and mount a free air subwoofer behind rear seats.

Re: E60 under seat woofer

Yes, i have done this for my car. But the item behind isn't an amp and the two woofers in my car were 6" philips powered by the built-in amp of the "factory head unit". If you want to change the woofers, go get the earthquake SWS 8 which fits perfectly (the 6" were mounted on frame which is the shape and size of the 8" earthquake). You can get them from Ebay (where i got mine), then go to a local installer and buy an amp to complement it. They will most likely tap power from the boot, line-in (tap from your rear speakers) for your amp and you are done. Don't forget to ask the guys to add a pair of tweeters in front (yes, behind the grill is pure emptiness and you can use the factory head unit's amp to do this) and you are looking a completely new sweet sounding system (in my humble opinion that is).

Re: E60 under seat woofer

I agree with longhorn. Have tried changing the underseat woofers but in my opinion, the best would be to hookup some freeair woofers on the rear parcel shelf. Which is the route i took. Never looked back.

Re: E60 under seat woofer

For my e92, original underseat is a pair of 6.5" woofer, not sure about the e60 tho. As I don't want to lose too much of my boot space, I changed to a pair of Hertz 8" and powered by a Hertz amp. Very big improvement from the stocks Good enough for me

Re: E60 under seat woofer

So today did the Focal K2 front and one more coaxial at the back. Vast improvement over the stock speakers.

Now the highs are too sharp, and mid is not clear enough. Separation is very good. Bass is fine although not enough punch at high volume.

Looks like I'll need an amp soon for more control.

Re: E60 under seat woofer

Today changed again, front and back Focal K2, used Steg K402 to drive them.

I must say now I can differentiate the percussions and much more details.

Still need some more proper bass.....any good ideas for minimal sacrifice of space?

Thanks

Re: E60 under seat woofer

Got an email Dav _C? Can email you some pics of my setup.

Re: E60 under seat woofer

Finally by today:

Steg K401 for front and back channels, with two pairs of Focal 4" K2.
Steg K201 for the under seat channels, with a pair of Dynaudio MW162.

Next should be a processor or sub.

I think this is problem for all the BMW drivers, why they don't just design it in the first place with 6" on the door? It will be much better save money and time, yet better result.

Re: E60 under seat woofer

I have the SWS in place for over a year now and it still sounds great, makes me smile everytime i crank it up

Since you already got an amp for the subs, why don't you just swap them out as there's really little downside.

 

[Dav_C]

Re: E60 under seat woofer

Changed again.

Steg 401 to drive the front Focal K2, and the under seat Dynaudio MW162
Steg 201 to drive the Rockford P3 slim enclosure (really quite thin).
The head unit is driving the rear Focal K2.

So far......not too bad.

Bro Keny,

Pls send me the pics of your mod if you don't mind. [email protected]

Kiam siah...

Re: E60 under seat woofer

My fiance has E90. I am thinking of putting in 6.5" SWS for her, some say 8" DLS can fit as well from some USA forum. Then add a pair of Focal K2. Maybe some Helix amp because it is very thin. She doesn't need deep bass or plays music very loud.

Anyone has experience in this can help to give opinion?

Re: E60 under seat woofer

Just put in the following items today for the E90:

Focal K2 Power 4" (Bought used at S$350)
Eathquake SWS 6.5" under the seat (Bought new at S$250 one pair)
Powered by Audison 4.1k (Bought used at S$700)
Installation S$350.

The sound is a little too bright for my taste although good for instrumental music.
Bass is not bad. But somehow lack of some 'warm vocal'....

For this budget, I think the result is acceptable.

Hi dav_c, may I know where you buy the earthquake sws from? looking for 8" to replace the underseat woofers.

Thanks.

Re: E60 under seat woofer

One shop at Eunos Technolink, at the ground floor. Something like 'AV one'. I don't think they have 8", but they should still have the 6"s

Re: E60 under seat woofer

Hi guys, how's the Focal K2 and the Eathquake SWS 6.5" under the seat doing after all these years?

Pretty new to this hence, I have a 4-channel amp to link up speakers and woofer. Would a processor really make alot of difference here?
