Enjoy them Clockwork!



PS: If anyone is looking for a pair of JL tweeters from the

JL AUDIO TR650-CSI 6.5'' EVOLUTION kit, let me know.



I have a spare pair

FWIW, I have replaced each OE speaker in my E53 with 4ohm. I rocked my 1st roadtrip today after the transmission. Very, very happy!

I'm still not sure why this works... but am extremely happy it does. Thanks for bringing it to the attention of the forum.

Oh, and I think I am going to start saving my pennies as well for trans replacement. Nothing funny happening yet, but I am getting ready to take it in for what I would assume is it's first trans fluid flush/fill at 111,000.

the key her is you replaced ALL speakers with 4ohm. So somehow the amp is still powering them and thats great, but if you were to mix and match the speakers impedance, then the 4ohm speakers would sound quieter than the 8 ohm, from what I've been reading anyhow.

needless to say I'm sure the 8 ohm Fountek's will be ok for me since I'm ok with the factory DSP stereo as is, but just looking for more high end (tweeters is all I probably need to replace honestly but I may as well go full meal deal)

Mike - you're overthinking again and its ok because it worried me at first too - each speaker gets a separate channel input from the amplifier so this is not an issue as they aren't wired parallel, on a home stereo setup this could be an issue depending on how you are wired - but its not an issue on our cars (as you know on non DSP cars there are 2ohm woofers x4, and 8ohm mids x4 and 8ohm tweeters x2)

The Founteks, JL's, Vifa/Peerless, Memphis all will be fine in their own right trust me - even just having (currently) the Memphis in the dash and the rest of the drivers are still factory 4ohm there is no issues with sound quality or something being quieter etc -

The only issue SemcoMike had was opposite impedence going from a 3ohm HK driver to the 8ohm Fountek on his E46 - Since we aren't going in the opposite direction there is no problems on our E53 to worry about -

We are only really debating midranges anyway but want you to stop worrying and just enjoy the better quality drivers -

As a result of this thread I have placed the following in my E53:

Dash Midrange: Memphis Audio PRX275 (4 Ohm?????)
Front A-Pillar Tweeter: JL Audio C2-075-ct (4 ohm)
Front Door Woofer: C2-600 (4 ohm)
Rear Door Woofer: Dayton Audio RS150-4 6" (4 Ohm)
Rear Door Midrange Position: JL Audio C2-075-ct (4 ohm)

I am very pleased with the sound quality upgrade running through my Eonon GA6166 HU. Nothing has blown up and I gave it a thorough 1200 mile shakedown cruise just after the speaker installs.

Based on how WOW'd I am with the Vifa/Peerless mids in my E46, I am ever so gently considering putting them in the E53 rear door positions.

When I get back to the E53 I'm going to sit in the back and listen intently to determine if I'd like a stronger mid range back there.

As I experienced first hand with the 8ohm Founteks in a previously 3 ohm factory position, the higher impedance/resistance knocks down the effective volume one hears from the higher impedance speaker. Assuming moderate power inputs, I would not think any damage to amplifiers would occur. BWTHDIK????

I am now thoroughly enjoying my E46 GM5150 Eonon HU. Once I heard what was possible in the E53, I cringed at the sound of my E46 factory 15 year old HK speakers.

This has been a great speaker upgrade thread and thanks to everyone for contributing their research and experiences.

Stay tuned.

Mike

Mike your posts have been extremely helpful and glad we have made this collaborative experience with Prop (the OG of this thread) to be super helpful to all in the forum -

I'm really looking forward to the JL C2 set of woofers, as well as the tweeters in my front doors - let me know how much you want for the tweeters if you do end up with putting a proper midrange in the rear doors (Vifa's) - I might use them in my fronts and just buy C2 woofers -

I'm sure I will be happy with the Founteks in the dash on mine when I finally get it out of the body shop and can listen to them, but I may go with the Vifa's in the rear doors just to mix it up a bit and hopefully be as impressed as you were -

Something new - Since this has turned into the master OEM+ upgrade thread for speakers, I'm now theorizing about the OE DSP woofers in the back, I don't have exact measurements but I know they are around 5-5.5" or so - I need to take some measurements when I have my car back - From researching the E39 boards and knowing we basically share amps, looks like each woofer gets about 20-40 watts RMS from an 8ohm load, and is dual voice coil.

Its been a while for me, but depending on how its wired, you could potentially (once I check measurements) use the 4ohm or 8ohm versions of these Dayton Audio 125 Reference woofers - they are efficient (87 db for 8ohm, and 89 db for 4 ohm), and the frequency range is almost OEM (65-5400 hz on Dayton's, 30-6000 hz on OEM)

Dayton Audio RS125-8 5" Reference Woofer

Wondering how I can make an OEM+ woofer upgrade and keep the DSP amp happy and healthy -


Only question is how would wire them without taxing the amp - if you wired both + and both - together on the 8ohm version would that be a total 4 ohm or 2 ohm load?

Isn't that what this is? (even if it is ugly)
