Good morning all. Preparing for new stereo install and think the old speakers (no idea what - they're almost certainly non OEM given the wiring bodge I've seen behind the console) are in a horrid state. Sound awful when driven a teeny bit loud. According to microfiche 284 the non-Bose units are 6.5". On a bit of searching here (and AndrewG's posts and FunkySi's), 6.5" speakers would need a spacer. Is that all 6.5"s or just some?

 

I'm trying to get stuff in advance without having to take the door cards off to find out because I'd have to do it again later when the stuff arrives! (You call it lazy. I call it being prepared :D )

 

Is this video the right method? I know it's about Bose and has the US belts in the door but other than that, is it a good guide?

from CarStereoRemoval.com's 300ZX page.

 

Thanks, Mike

In my experience all 6.5" speakers when using the OEM metal speaker brackets Mike. The MDF spacer rings (RW-SR-16) need

routing to create a chamfered 45deg edge to them to fit. If you don't have a router I will do them for you. The guide looks good.

Take care when removing the window switch escutcheons othewise you can break the plastic spring tabs that clip them in place

Thanks AndrewG - PM sent.

 

BTW any suggestions for which speakers? To go with JVC 50W DAB head unit

BTW any suggestions for which speakers? To go with JVC 50W DAB head unit

It strikes me that (while not necessarily ICE geek material) JVC are a perfectly competent audio manufacturer (I only just sold my 1980s JVC cassette deck) and their head units have been good, so why not go for JVC speakers? E.g. http://www.caraudiodirect.co.uk/speakers/full-range/jvc-cs-dr1720-17cm-coaxial-speakers I'm not intending to enter any ICE competitions or have ear-bleeding SPL.

Good brands are JBL, Infinity Kappa, Alpine and Kenwood....

I would stay away from cheaper brands....

 

My personal choice is for JBL and infinity.... but then i have always been picky for a certain sound.... lol

http://www.caraudiodirect.co.uk/speakers/full-range/jbl-stage-602e-6-5-16-5cm-135-watts-2-way-coaxial-car-speakers

These are on special at the minute....

 

JVC are a well known and long standing brand, so they should be good as well....

 

The headhunt output is Maximum Power Output - 50W x 4 / 50W x 2 +Subwoofer (4 ohms) 50W x 1

Full Bandwidth Power (at less than 1%THD) - 22W x 4

 

so pretty much a speaker that will not be under or over driven is where you want to be....

Aha - they're neither 6.5" nor 6" - they're 16cm! Which is pretty much 6.25". Inspired by that how-to video, I bought some pry-bars and set to (sunny day after The Archers).

 

As you can see the roll surround is toast - thought they were sounding rubbish. So thanks for the suggestions, I'll go read up. From memory, I had a pair of 8" JBLs some decades ago in the Capri :)

 

From the part numbers on the magnet, I'd guess these were original factory fit.

 

Why do they bodge the wiring? Couldn't be bothered to get the right connectors, lazy b'stards.

 

Hunt the screw - discovered the hard way that the little screw at the top of the door pillar trim wasn't magnetic. Bugger. Luckily hadn't gone too far so could peel the foamy thing back and hoick it out. Not the first screw, bolt, clip I've lost down in the depths of a Z and probably not the last. And I'd bought magnetic screwdrivers specially!

 

Right that's it, time for the pub :D

I have those same speakers and they have perished all the way around. I need replacements too. Did you find a replacement or alternative? If so what did you use?

I bought a pair of these https://www.ebay.co.uk/itm/JVC-CS-J620X-6-5-16cm-2-Way-600-Watts-Car-Van-Door-Coaxial-Speakers-Pair/171420040661?hash=item27e96e3dd5:g:j2YAAOSwnDZT6-py purely on the basis that JVC "should" be OK and match the head unit I haven't fitted yet. They measure exactly the same 16cm dia so they "should" be direct swap.

 

AndrewG suggested to get some foam for the surround - he's right because that foam seal is crumbly and u/s. He suggested https://www.ebay.co.uk/itm/Regin-Single-Sided-Foam-Sealing-Tape-12mm-X-12mm-REGJ60/360392257558?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 and I ordered some which has now arrived.

 

I also found adapters https://www.ebay.co.uk/itm/72-9300-Car-Auto-Speaker-Radio-Audio-Harness-Wire-Connector-For-Nissan-Mazda/174039508291?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 (I suggest a bit more searching as these ones are from Malaysian seller despite it saying they're posted from Hayes and took 9 days to arrive) so I'll be seeing if I can reinstate the OEM harness and remove the bodged extra speaker wires.

 

When I took the door cards off, one of the trim clips was borked so I found these https://www.vehicleclips.co.uk/trim-panel-moulding-clips-nissan-0155309791/ and they've now arrived.

 

Now the saga over the head unit screws has been resolved https://www.300zx.co.uk/forums/showthread.php?190919-Radio-fixing-screws and I've got the conference I was at out of the way, I guess I don't have an excuse to get round to fixing them - other than the weather :) so it looks like not this weekend hoho.

Excellent news Mike - and some really helpful links there too...:thumbup:

Thanks for the detailed help and guidance. I’ve ordered all the stuff I needed thanks to your advice. Just waiting for it to arrive then get it installed and tested.

i did mine last year, i bought some speaker adaptor plates from the usa, they were made from thick abs but were a straight fit

Where from? Looked at CZP and cant find them on there. May see if I can either laser cut or 3D Print some at work yet.

or directly from here http://www.car-speaker-adapters.com/items.php?id=SAK005

I think Laser cutting these should be straightforward - didn't realise it was the whole thing thought it might have been an adaptor to fit on the existing metal bracket.

You are better off using the OEM metal speaker brackets which will (with new sealing foam) properly fit

the aperture and contours of the inner door panel and the door card to give the best acoustic sealing.

Get them s/h.

 

The picture first picture shows the old sealing foam in place on the reverse. The second on the front face.
