Need advice on dash speakers that fit

Hey and thanks for the help! I have a 1982 Z28 I am currently restoring. I am having some trouble finding the right speakers and I would like some recommendations . I am aware that they are 4x6 speakers on the dash but not all of them fit due to the magnet sizes and the odometer and vents that are there. I would like to not alter anything unless I have to. Looking for some nice dash speakers that fit right in without compromising sound quality. My budgets all over the place , If i can find something that is a quality and affordable that would be my choice. But if I have to spend some money I will.

Re: Need advice on dash speakers that fit

4x6 is a pretty tough size, not a lot of good sounding speakers. I tried some cheapo Pyle speakers from Amazon first, didn't sound much better than stock. Tried a NOS set of Alpine Type S 4x6s (had to get NOS since Alpine no longer makes 4x6s), sounded a bit better, but still not great. Now, I've run a set of Infinity 4x6s for the last couple years, but NOT the Kappas; they're the Infinity Reference REF467F. Tight fit with the capacitor on the side, but I did not have to cut or bend anything in my dash. They sound pretty dang good for a 4x6, though I am also running them with a 50W RMS x 4 channel Alpine amp. I have the front speakers set to get around 35W at max volume (speakers are 45W RMS, wanted some headroom), and they sound shockingly clear. Don't expect any bass from them obviously, but the highs/ mids are great. They go for $110 for the pair on Crutchfield at the moment, which is actually the same that I paid for my set back in '22 or '23. Nice to see that they haven't gone up in price.

The speaker pockets in the dash should be the same in an '82 as they are in my '92, but I cannot confirm this.

Edit: Dave is right as well, Camaro dashes are different. I also have a Firebird, so I couldn't tell you how they'd fit in a camaro. All the dimensions are listed on Crutchfield, so you can take some measurements from your dash and cross-check

Re: Need advice on dash speakers that fit

Being that I have a Firebird, and the dashes are different, the Infiniti speakers I used may not work for you. And I did have to make some modifications to get the to work (in the driver's side). But for reference....

Re: Need advice on dash speakers that fit

The Kappas are better from my understanding, since they use two separately mounted speakers vs the regular oval woofer with a central tweeter. That, however, is also why they require a bit of cutting in the dash to fit (which you can see in the thread that Dave linked). They're also about double the price of the Infinity Reference speakers. Couldn't tell you how they compare since I've never heard Kappas in person

Re: Need advice on dash speakers that fit

I used Kenwood KFC-4675C in mine. No cutting and they fit fine. They sound ok but not great. I'm running them off of Sony XAV-AX1000 head unit.

I'm interested in the kappas. Only thing is that i am probably going to have to modify my dash from what i am seeing

I used the Infinity Reference 6432CFX and they fit perfect, with no modifications.

Re: Need advice on dash speakers that fit

In my TA I went with 4" round speaker adapters and these
Amazon Amazon
.

Sound good enough. Running them on a Skar amp along with the rears. Hard to get any kind of quality sound on small speakers that point up to the windshield inches away.

Solid. I'm a fan of Infinity all around, so I went with the 6x9 reference series in the sails, as well. They get the job done, I don't have any complaints. I'm sure there's better stuff out there, but with the amount of road noise that comes in, and keeping the windows down 90% of the time, I'm not missing what I wouldn't be able to hear anyway.

Re: Need advice on dash speakers that fit

I have an old set of cerwin vega (HED 1462p) plate speakers. Barely fit in the driver side, only had to mod the steel frame that holds the speaker. No issue on the pass side though

Re: Need advice on dash speakers that fit

Now what about those owners, like me, who have the 8 ohm speakers? Above mentioned speakers are 4 ohm. What is recommended for 8 ohm speakers for front in dash?

Re: Need advice on dash speakers that fit

[size=13px]MB Quart Formula 2 way 90w 4x6 speakers are what I installed in my 89 base model Firebird. The passenger side fit nicely, but I had to modify the drivers side dash to make the speaker fit. They sound great but I would have chosen others if I knew they didn't fit. [/size]

Re: Need advice on dash speakers that fit

Most of the replies are from Firebird owners, not Camaro owners. But that's good, because if it fits in a Firebird dash, then it should fit in a Camaro dash.

Look for speakers with a mounted depth range of 1-1/2" to 1-3/4", and they'll fit without modifications. Some might even be called "slim mount." And if you're going for 2, 3 or 4-way, then make sure the center tweeters/midrange speakers do NOT stand above the top of the speaker's frame, or, at least, not by much, or they'll hit the bottom of the dash.

If you're not a blaster of your tunes, you know, where your car vibrates like a tin can, and the cars next to you feel it too, then differences in ohm ratings aren't going to be critical. 4 ohms seems to be somewhat standard, likely because that rating is basically "universal" for normal use. I don't mean to challenge anyone's expertise, but unless you're building an award-winning sound system, where matched parts are critical, then an ohm rating of 4 will likely be fine.

That's not quite right with an old school factory Delco head unit. Most aftermarket speakers are 4-OHM and most aftermarket radios are made to handle 4 4-OHM speakers. 4 4-OHM speakers is NOT a good idea when connecting directly to a factory Delco. ( Installing 4 10-OHM speakers will not harm the radio,.. but sound quality will 'suffer'. )

https://berlinetta.info/video/4OHM.mov ( Capacitors,.. not Resistors ! )

Here's the rub ------>

There are scenarios where lower ohms might be the better choice. For example, in car audio systems, lower impedance speakers are often preferred because they can produce more sound from the limited power available.
While accurate, ( sounds a little "better" ) it doesn't take into account the radio being used and the harm it causes because it can't handle that extra load placed on the AMP chips inside the radio. The reason I bring this up so often is because I repair old Delco radios,.... so I see burned out DM165 chips way more often than most folks.
