I recently installed a pair of brand new Alpine SPR-69 2-way 6 x 9's in the rear stock location and they sound like crap (1980 Corvette).
I also amplified them and they still sound bad?
They crack and squeak behind those plastic grilled covers.
Is this normal? Should I just mount them in wooden boxes to get the
full performance out of them?
I kinda wanted a stock look but I guess I'll have to build some kind of enclosure.
Up front dash I've installed 4x6 Pioneers and they sound great.
My head unit is a Pioneer Bluetooth/USB Receiver.
Thanks

Back in the day, sorely disappointed with the factory 4-speaker option that originally came in my '78, I installed a nice pair of smallish self-contained 2-channel box speakers in the rear compartment and positioned them to reflect off of the fastback window. I forget what brand, but they sounded pretty sweet in comparison.
...at least they did so prior to the BBC / Hooker sidemount upgrade.
https://www.bing.com/images/search?q...kers&FORM=IGRE you can get them at most audio sales places or you can order from crutchfield.They stop the bass signals from going to the small speakers that cant handle the bass .That allows you to get the bass from the speakers that can handle the bass sound .But if your rear speakers sound bad or distorted at any level then remount them or replace with different speakers.Lots of choices.
Hmm... I installed the Alpine SPR-69 2-way 6 x 9's in my '80 as well because I wanted to keep a stock look. I'm no auto audiophile, but I felt they were a vast improvement over the originals. I added a small powered Kenwood sub in the passenger storage compartment as well as newer dash speakers (and a Kenwood head that's 2-3 years old), and I'm happy with the setup. No cracking or squeaking (but not amplified other than that head unit).

I just did an install this weekend, used a pair of Cerwin Vega bookshelf speakers I had from an old surround system. Still haven't tweaked the headend for the best sound, but they look nice, and will definitely be loud enough for me.
I hid the amp under the passenger storage compartment tray, trying to keep the interior "stock" looking". It's 125 watts per channel, so I should have plenty of kick, even with the little speakers.
Thanks for the reply. I see there are other options for having mounted speakers and room for the tops. I really want to fix my setup since I just have a couple of loose 6x9s in boxes in the back and it is really annoying.
Here's another option. It mounts to the inner wheel well walls. I won't claim awesome sound, but it's decent and is out of the way. No problem with t-top storage. In retrospect I might have experimented with speaker enclosures a bit.

putting a small wooden enclosure behind your speakers would give it a deeper richer sound, you may be able to add some if the clearance isnt and issue. Some audiophiles could stell you how much volume you need but it may be total box volume and not space behind the speaker. I like the construction and the idea, and its up out of the way. In the installed pic, Is the opening for the window or is it a convertible? its hard to tell at the pic angle.

Thanks Scott. I just went out to the garage to give a listen and have a look. Let me put things this way "I know it's only rock 'n' roll but I like it, like it, yes, I do". Not going to mess with it. It would be nice to have a front center speaker but that's not going to happen either.
The car is a coupe with a removable window. Generally rear storage is a mutually exclusive situation. If the window is in, the tops are out, and vice versa. Works for me.

For me, I removed the t-top storage problem from the equation and now mount them on the luggage rack. This allowed me to build an mdf speaker box to mount a 10" sub, put my amp in the tray above the jack storage compartment and 6-1/2" speakers behind the kick panels. I also noticed that the sound from the speakers in the kick panels sound like they are coming from there as well as the dash but there are no speakers in my dash. Just to note, a guy once said that if you were at a concert, the music comes from the front and nothing in the rear. So why have rear speakers? Makes sense to me but some folks spend a lot of time installing/upgrading rears when they really aren't needed for good sound. Just sayin'.

because your car isn't a clam shell design specific to relaying sound, neither is any modern concert hall, they all use speakers for surround sound, You wouldnt want to listen to Led Zepplin with only 2 speakers, same with Pink Floyd. Those bands and others including The Who depended on the Quadraphonic sound that they were so proud of during the 60's and 70's. Listen to any Album from those days with decent headphones and you would hear the time and energy they put into their mixing.You can hear it with jsut four speakers on a 4 way system but you would need to balance the system to where you are sitting to get the surround feeling.
Now for the bands of the present day, ya, you could listen to them with a string tied to a can and they would probably sound the same.
