I am consider getting a SWS-8 underseat subwoofer upgrade but I am not sure how much it improves bass in the car. Can someone who has experience with it help me out?

Uhmmmm, why don't you ask amlebede? He/she is also from Chapel Hill, also drives an 06 330i, and also works for plusplustutoring...what a freaking coincidence! Amlebede seemed to pretend to have a wealth of knowledge on the subject of car audio so you'll be in very good hands!

What kind of music do you listen to? Do you have the ski pass? The 8" subs under the seats don't allow really low frequencies...you need a 10 or 12 inch sub to get those low lows. I did the SWS-8 upgrade and was disappointed. They do increase the quality and depth of the music however I used a monoblock amp and that might be my problem because alot of the midrange frequencies require stereo input. But anyway I know that changing the amp to a stereo amp won't make much difference in the way it hits low low frequencies...only the quality of the midrange frequencies. If you do NOT have ski pass try the SWS-8 before adding a trunk sub. Adding a trunk sub without the ski pass may just make your car rattle more than produce the bass you want. BMW trunks are well insulated and don't allow much air to pass through to the cabin, greatly reducing the output heard within the cabin itself. If you do have a ski pass and really want those lows then I would add the trunk sub. I just picked up an Alpine MRP-M500 amp and Alpine Type-R SWR-1242D...both are rated at 500w RMS to add ontop of my SWS-8's. If you decide to go the trunk sub route, I might want to get rid of my Alpine MRP-M500 and get a 2 channel amp with 150w RMS per channel for the SWS-8's (currently powered by a JL 500.1). Let me know. I'll let the Alpine MRP-500 go for 100 shipped. Only "problem" with the amp is that the covers for the wires are missing. It's only cosmetic though...the amp performs fine.

I do not have a skipass but I do have two 12'' Rockford Fosgate P2 in the trunk. The higher bass doesn't really go through as well.

i changed from the worst speakers, philips. to sws-8, and i feel okay. but i spent a lot of money and time on changing them. so. i honestly cant hear alot of difference from my sounds upgrade to my friends profession sound system.

but if your sound sucks, yeah sure why not, its not THAT good. but its okay

I am primarily trying to see know what the difference between the Logic 7 stock underseat subwoofers and SWS-8s is. How much better are they?

[fdiprete]

for the op:

they help a little. they make less noise than the factory "subs" do.
less noise = more music.
What they do not do is provide power that isn't there.
sws + better amplification helps more.

[chemgeek]

How much sound do you want out of those under seat subs? Even those SWS-8's can move much air, so I don't understand how anyone expects them to produce the ghetto bass that everyone seems to want. At a whopping 4 lbs, the magnet just won't be able to move the speaker to any appreciable distance. Plus, you are paying a price premium because those have to be limited application subs, aka not a huge supply (I mean who really uses a low profiled 8" sub?).

Something else to consider, short of obnoxious ghetto bass, you can't possibly get that much bass effect in an E9x. The road noise, sound isolated cabin and harsh suspension have to cancel most of it out, even if you had a properly amplified 12" sub in a hatchback box in the truck.

So it will be much better than stock sub if I add an amplifier?

Ghetto bass is bass that shakes the license plate. You know, when you hear and feel a car pull up next to you, you turn and look and it is a lowered, tricked out Civic. Or in this case an e9x.

So Dynamat is a solution to "ghetto bass" I guess.

I think you missed the point completely. The point is that the bass is the goal of the system and having your entire neighborhood know when you are comming and leaving your house is ghetto bass.

Really bass should be just another aspect to the whole sound system dynamics and range and not the goal to have the loudest car on the block.

Thats ghetto bass and is has nothing to do with sound deadening materials.

Maybe some people just like more bass.

This is a legitimate account. I do not use amlebede anymore. This is a new screen name.

Wow... then the bass the BMW system generated must have been just fine for you?

As a representative of the professional installer community, I would say that when I've heard that term used, it refers to bass that is loud, distorted, out of proportion to the rest of the system, often crossed over so high than vocals are clearly audible out of the woofers, and generated by a system wiith low-quality equipment and poor install, verging on electrically unsafe.

While it's not a term I use, it has seemed to refer to the sort of bass capability purchased by someone who wanted bass, but did not care much about the rest of the audible spectrum, and who used a very limited-performance playback system as a reference. I'm told that boomobxes distort when played really loudly, and that's one reason that some people expect lots of distortion with a loud system.

Anyway, that's what I heard.

Yeah but when you do a sweep you should be at the same level across the frequency range, well within a DB anyway.

Ghetto bass is when these guys get a sub that is tuned to around 30-35hz and drowns out everything else.
Great if you are listening to....... well, nothing really, it is great if you want to get everyone looking at you, but not musically at all.

I really like the earthquake subs, if you seal them properly around the driver so the port going into the sills is the only way air can get out then they go down to a genuine 28Hz, this will cover every type of music other than some organ music.
You will need an amp to drive them as they are not as sensitive as the OEM subs to you need to be able to match the levels to get them loud enough, but once done they are superb.

anyone have their stock underseat subs? I need the passenger side one, mine blew=(
I have an 07 e92 335i with navi/l7
