    The Sony sub amp runs class D with around 300 watts RMS into 4 ohms at 13.8 volts. (engine running with alternator charging)

    Used to produce good clean bass results with around 300 rms so the box is the key to overcome the challenges of the e36's well sealed boot.

    Mind you , power ratings can be interesting. Had an PG amp rated at 4x25 rms for the 100 watt car stereo class that used to exist. At 12 volts into 4 ohms you got 25 watts. At 13.8 volts you got 75 rms x2 = 300 rms x1 bridge. This power was plenty for nice high quality sounds with more that enough volume to overcome car and road noise.

    Hope everyone is alright in Christchurch.

    I was in a Qantas jet about 5 minutes away from landing when the first one hit. We held for a while then went to Wellington, where I will be until lunchtime on Christmas day due to there being no seats tomorrow. Wonder what state my house is in?

    Still it could have been much worse.

    Have you got somewhere to stay in Wellington ? Your welcome to stay here , Can pick you up / drop you off if needed.

    I have a chance to get E46 M3 wheels, the rear wheels are going to fit fine, but fronts are ET41 I think, so not so good, but I might get spacers for the front :)

    Have seen the fronts in a 8 1/2 as reps. There was a pair on TM for serval months. Something else to consider.

    The 17's sound like a good way to go as well.

    are you using anything to stop boot rattle?

    curious as I'm sussing out ways to stop mine, by the time you can hear bass you can also hear a lot of boot rattle, it's really annoying

    I had bad boot rattle when the rear spoiler bolts backcame slightly loose (try grabing spoiler to see if noise reduces) , Other areas for attention is rear number plate mounting (Put a clouple of strips of foam door surround sealer under it) and rear boot lock. Also make sure that boot rubbers are in good condition

    Hi there, I just bought a BMW Z4 3.0i 2004.

    I am seeing a double image in the auto-dim rear view mirror. Can this be fixed? Or does it need replacing?

    Thanks for your help.

    I recently had the rearview mirror bubble of death ( Just before the point where they dump acid all over the interior)

    Sent it to the USA and it repaired and sent back with new autodimming glass where the gel doesn't break doesn't to acid over time. Took less than two weeks and cost roughly $250 nzd

    belowis an email I recieved from them in regards to an Oval M3 Mirror I needed repaired. I called them with credit card details rather than mailing it.

    Have measured a 3 db difference higher in my old e36 with sub box running in back corner of the boot compared to middle boot up against back seat. Suspect it coupled with the car better in that position. However I prefer the quality of the bass more in the middle, timing seems to be better.

    Having said that try running your sub 180 degrees out of phase to see if it sounds any different. You maybe getting phase cancellation in your midbass from your fronts depending on your subs HPF and your midbass LPF points and the roll off rate your crossover is running . (e.g. bass between the sub and fronts partly getting cancelled out between 70 - 90 hertz making it sound like less Bass)

    These Altenzo share the same spec for grip and tyre as a Pirreli P6 (AA 320)

    Grip is one A with AA being highest.

    On paper they have more traction than the majority of Firestone tyres that NZ'ers love to put on there cars so they can't be that bad.

    My own pref for road tyres is for AAA with 180-220 treadwear with bridgestone being the tyre of choice for the last 4 sets based on price / performance.

    Rang the local Firestone dealer for a set of Re11's for the M3. Got called back saying that bridgestone in not carry the sizes I'm after anymore but did offer up Re002's. I'd rather not go that way.

    Any Bimmersport suppliers got 2 x 235/40/18's & 2 X265/35/18 Re11's sitting on the shelf ?

    Update:

    Have been able to place a factory order for rears via Bridgestone NZ for the rears. These guys have been exteremly helpful. Will take a few months for them to be manufactured / sent to nz which suits the timing for the rears I will need.

    This story is all over the interwebs now, funny how it seems to be concentrating on the fact that the crash involved eight Ferraris and 3 Mercs, rather than how badly any people were hurt. Worse crashes, in terms of human fatalities, occur every day around the world but are not reported to the same level. Says a lot about the world today, sad.

    Yeah , sorry , didn't mean to undermine people that may have been hurt , but that's a lot of eye candy cars that are wreacked.

    Probably should have posted something like this clown .....

    M3's have spare tyres ? Unfortunately they don't due to the smaller tyre well to allow M3 rear muffler. All you get is a compressor and tyre gunk and more room for car stereo's

    Very nice tidy install. Was that a E46 m3 or a larger E46 boot well ? I'm planning on putting my amps in the same location. Also gives stealth install and retains full boot use.

    I'm thinking that the depth of the tyre well will limit your sub to more shallow depth models. From memory there is a metal bracket that would need removing to allow enough depth smaller subs unless if you use super shallow subs (Like the 13 inch soundstream)

    I do like the idea of the IB sub Rogan has talked about , sounds like they have come along way since the earlier Cewin Vega's , infinities or JL audio's

    I wouldn't go with 2 x 17cm bass units suggested, you problably had the two 6X9 HK subs which would produce similar levels of bass and hardly any sub base. (These provide only mid bass really )

    Rogan may be able to suggest a shallow mount sub that would go in M3 boot well. Your high powered amp is the issue and does limit choices somewhat.

    In term of the audio feed to the sub amp, I'd look at modding the BMW tuner stage by adding RCA outputs to feed the sub amp rather taking a speaker type feed. That way you can get a cleaner unclipped feed into the sub amp and set it up so that it never has to clip the signal. BTW , did you earth the amp to the chasssi or take in back to the neg battery terminal.

    With an amp that size, get a heavy duty sub with a single voice coil with a similar or larger power rating to the amp and make sure that the box is of the right size so you don't mechanically overdrive the sub.

    Seem strange to to do a voice coil if your putting clean and un clipped audio through, Do you like serious amount of volume ? What's the rest of your setup.

    BTW, Looking forward to hear 3pedals car audio setup at the next SQ Car Stereo comp. I’m ready to be enlightened on quality car audio.
