Mr Vlad

Have you taken your door trim off yet? Best you do before it does your head in.

Yes looks like components in the front. From what I quickly Googled they are 6.5" and 2ohm.

Maybe I am Rayaans but 4 years is a helluva long time in technology world. Steve. My domestic hifi hasn't been used in over 10 years now. It was arguably one of the best money could buy but I spent more time in my cars than at home lol so in car hifi became a semi pro hobby and my systems suprised home hifi dealers when they listeneed to my systems. Urgh radio 4? Noooooooo. Braingell for me. Metal till I die.

Sorry Rayaans but ML isn't the company it was when it 1st started and it's ethics in sound reproduction. What it is now is a marketing tool. Yes now they produce better than most car audio equipment but it's just too different between Lexus models. My current RX is a 62 plate registered 2013 and it's ML system is not as good as the 2nd of my IS300h's whose ML was superb. The ML in my 1st IS was utter shyte. Yes systems now in cars have their bass boosted probably coz it's cheaper to do that than properly sound deaden car body panels. I can make any car sound better than ML for under £1k probably £800. Rockford Fosgate amp £300. Infinity speakers £350ish. Alpine sub £125 and a couple rolls of dynamat plus wires/leads. Yes Comedian some home systems have 2 or more subs running but they'll be run from dedicated sub amps. Before buying my Alpine sub I ran a custom designed by Wilmslow Audio (1980''s original company) 4th order bandpass box which had 2 10" speakers facing each other but in separate enclosures with just one 4" hole for the sound to come out. It was designed for home use. I guinea pigged it for car use as it was only about 2 foot cube. Acoustic Research AR9''s have 2 subs in each speaker making a total of 4 subs perfectly matched powered by BBC grade Quad amps. And yes if you can hear where the sub is then something is set up wrong. You feel good sub bass.

You know what Rayaans even tho I've not heard a none ML Lexus I'd be inclined to accept that there's very little difference between the two. Neither of the ML systems I've had were/isn't as good as the £600 system I had in my previous Ford Mondeo.

It may be able to shake the doors But the issue is its low quality of sub bass. What gobsmacks me is in the RX ML system is only around 300 watts. The ML in the IS300H is a mighty 835 watts. Also the RX has pityful sound proofing. The door skins are so so tinny. Most definitely need treating with dynamat. There's always room for improvement.

That's very interesting. When I enquired I didn't mention a hybrid health check. It was others on here who stated even catagorically that only lexus could do the HHC. Good on your Toyota dealer.

A decent paint shop will actually remove the sensors. All sensors are removable.

Actually painting sensors is very common and has no detrimental effect on them. Possibly tho having 2 coats of paint may affect them but I suspect the coat the repairer put on the sensors hasn't taken to them. Take them off and use a 2 or 3000 grit paper to take that layer of paint off.

I found the quotes I got when I phoned my local Toyota dealer. Full service for the IS300h £330. Intermediate service £180. I do remember tho that who I spoke to asked the service manager who themselves sought advice and permission from Lexus.

Try your local Toyota dealer. I know they will service a lexus and to top spec but you'd have to go to lexus for the hybrid health check. Oh Toyota charge half what lexus do. I enquired when I had my IS300h.

I saw a RX300 today and what made me smile is that it had 2 either washing machines or tumble dryers fully in their packaging in its boot. Blimey a luxury van lol.

There's an organisation called EMMA who are like an umbrella organisation looking good after the UK's car hifi stuff. Go on their website and check out car hifi dealers in London of which the major ones are there. There's one Big problem running another sub alongside the ML one. It'll sound even worse. Something to do with frequency cancellation and a minute time difference between the two signals which makes it sound awful. Do you know where the ML amp is in your car? If so then simply disconnect the sub and install a different sub of your choice (the Alpine I mentioned is unbeatable and worth 5 times its price)

Unfortunately I don't have a link to any mods for lexus audio. From your thread I looked into removing the sub. It's quite a job from what I've seen and I was gobsmacked to learn it's one speaker in a Plastic L shaped box. No wonder the sub sounds wooly. I have an Alpine SWE 815 powered boxed sub. It's only 8" speaker and 100w but believe me it packs one helluva punch. It shook the glass in a previous Monday I had it in. Google an upgrade to lexus audio and you'll find about the sub in the ML system. I think there's one or two on ebay.

Shame Lexus didn't put a duplex system on the f sport variant of the RX and more of a shame they hid the exhaust end on the hybrid.

Hi Fatts. I've just come across your thread. OK it's been a year but have you sorted getting better sub bass? If so how did you do it? I know for the 3rd gen IS300H with ML there is an upgrade c/o our American friends.

I wouldn't use any kind of silicone or sticky tape coz the sunlight will knack it up. Best either buy new from the link above or as above also a small drill bit and self tappers. I speak from experience with the same problem on a MG ZT I had some years back.

Before a car hifi dealer closed down (due to retirement ) they had a visit from either JBL or Clarion I can't remember but they were showing off a new low voltage and wattage system developed for the new breed of electric/hybrid cars because of the lack of sufficient 12v supply. I think the system ran 20w at what ohm I don't know but apparently the sound was really good and sound level as loud as any true 100w. Anyway I'd guess in the RX300 the speakers would be possibly 8" or 6" running with possibly 3 or 4" and tweeter. Door panel off and access speaker and look at label as stated earlier.

That's what I thought John until I spoke with a couple of car hifi installers who suggested otherwise. Maybe because they were reluctant to work on a hybrid car. But as I suggested. By taking a door trim off and physically looking at a speaker can you tell. But I do think that speakers in hybrid/electric cars are so much more efficient so they work better from amps that are lower power rated (in their input I mean, more in more out etc etc)

Best thing to do it take the door trim off and take the speaker out then look at its label and replace with similar spec. I'm assumingyour car is a hybrid as I don't know the model. If it is hybrid then you're goosed. If not then there will be replacements available. What is your car similar to?

Hi Steve. The differences between the 2 is300h cars were numerous. Ride, comfort and the mark levinson system was hite (with a S) . 1st car lasted 5 weeks. 2nd superb car lasted about a year but changed it to my current RX450h f sport with Mark Levinson. I'd have liked the premium but the f sport looks so much better. It's ride is very good with no issues.

If I were you Steve I'd go test drive a different RX premier. Why? Because my thoughts are that unfortunately you have one of the very few rogue cars. I've had 2 exact same is300h and both were like chalk and cheese. Go test drive another and give it a good test drive. I think you'll find the car you test will be totally different to yours. Make sure tho it's the same year and model.

OK Ed I see your point. A lol to your wife too.

Well another suprise from my car. Wow what a boot. I got the base of a 6x4 shed lay down in it.

You knowwhat Ed the RX isn't the big car loads think it is. It's not much bigger than the NX (both cars were next to each other when I went for the 2nd viewing of the RX). I may have gone for the NX but it's boot was smaller. My RX is only a couple of inches longer than the IS300h I had but oh yes it's tall.
