Neil Martin To beat the headphone law, check out Boses' new sunglasses with bluetooth earphones. If only they were available in prescription.

architeuthis i had an '84 spider when i was in college in the late 90s. I got two 6x9s in enclosures and ran wire under the carpet to the back. they just sat on luggage shelf and had just enough juice and clarity for me.

1978alfa I upgraded my '67 duetto with an 85 amp alternator, installed a decent CD player with AUX input (no amp) and bought
some sturdy speaker boxes with some decent 6" x 9" speakers.
They're wedged in behind the front seats.
Agree with other posts about the open air with highway noise / carbs / exhaust sound.
I can really only hear the music well when I'm sitting at a red light or if I have it turned up really loud.

Get a bigger alternator, and wiring ?

Boattail

First thing you need to do is get a bigger alternator. Get a 75 AMP alternator from a later spider. Or better yet fit a modern GM alternator (are you in the USA?) if you don't do the wiring yourself, inspect it very carefully. I've seen several classic cars suffer electrical fires as a result of improper stereo installations.

The stereo wiring should be it's own separate circuit(s) with it's own fuse(s) It should have no connection with the existing fusebox.

Craig_m67 Have a look at how convertibles have done it.

There was an early Porsche (boxter?) that had a tuned port enclosure made out of ABS plastic that sat in the boot, porting through the rear firewall for bass. Mids and tweeters then don’t necessarily have to be loud/strong.. just matched and in good positions

Mario Romagnoli I had a '69 Spider, and the PO had gotten a rear parcel shelf from a late Series 2 or Series 3 and mounted large speakers in it. It fit perfectly behind the front seats in the back "jump seat" area.

He didn't even need to screw it down, because the weight of the speakers was sufficient to keep it in place.

60sRacer Thousand Oaks - just down the street from you.

I was referring to the little in-ear buds. Actually don't need noise cancelling. I use a bluetooth headset that I also use for running choose not-white, not-iPod and they are nearly invisible. I've been stopped for loose tail light and chatted with the CHP by pulling one out of my cop-side ear and never had a problem. Maybe because it looks like a hearing aide on an old goat.

I did get a warning a few decades ago when I was driving with a gigantic over-the-ear Koss studio set in Connecticut. Was in uniform at the time (Air Force) so that might have gotten a pass....

VenturaAlfa 60's racer, not sure where your from, I thought it was the U.S.

Technically, noise cancelling in-ear headphones used in both ears are illegal in all 50 states. That law is actually enforced in California.

Reason that law enforcement, fire departments, and ambulance companies object to them is that they prevent you from hearing approaching vehicles with their sirens on.

I know the same argument could be made about loud music but I will say I hear a siren over loud music that I don't hear when riding as a passenger with headphones in.

In California the ticket for headphones in both ears can exceed $400.00.

I would be pretty obvious with headphones driving a drop top and I would rather have the loud stereo than the ticket.

60sRacer Why not just a simple stereo with noise-cancelling in-ear headphones? Solves all those problems, and won't disturb all the neighbors, nor chop up a nice, simple Alfa.

VenturaAlfa I felt the same way in wanting a good stereo so I put in a Sony MEX xb100bt. Most powerful head unit with built in amp; 100 watt. Then I put a pair of boxs with 6x9 3 way Sony speakers in the back faced towards the seats and 6 1/2 inch 3 way Sony speakers in the kick panels. Sounds decent and can be heard at above freeway speeds. Main disadvantage is that you lose almost all of the bass with the open car. Sony head unit has a mega bass setting on it and there still is not that much bass.
If I was going to do anything more I would add an amplified sub to the car but I think I'll never quite get the sound I want so I'm probably done.

Interesting side note, I have a 74 Jensen Healey also and that car is much quieter with the top down. Similar stereo mounted in the same way and it is much easier to hear. Not sure why but the Jensen Healey has much less wind noise and tends to block the sound of big rigs going by me better. Part of that may be the seats which are high back contoured recaros.

For each his own.

I've concluded that if a vehicle is not worth listening to it's probably not worth diving, unless I'm towing a boat.

AlfaEmitter I do the same. The nano-sized ipod fits nicely in the Duetto ashtray. I don't think a full-blown stereo in a noisy-by-nature convertible would add much. I save the automotive stereo experience for the 330 ci.

alfasrule I made a speaker enclosure to fit in the rear of my Spider. 8" woofers, 5" Midrange and 3" Horn tweeters. Finished it to look like the steering wheel.
Also mounted 2 6" multi range speakers by the lower kick boards. Didn't like cutting holes into my new door panels.
Just have a 50 watt system, but I bought an amp to install in the speaker box.
Box is cool cause I didn't cut anything and just ran the wires under my mats.
