Help with selecting dash and kickpanel speakers
The head unit and amp was given to me by my son and the speakers I already purchased.
What I have already.
Head unit - Alpine CDA-9886 http://www.manualslib.com/manual/249...?page=3#manual
Amplifier - JVC KS-AX7300 http://www.manualslib.com/manual/814...00.html#manual
Speakers - Alpine SPR-69 2-Way 6" x 9" http://www.alpine-usa.com/product/view/spr-69/
Car - 75 Coupe.
Budget - $150 per each set (total $300.00)
I would appreciate some suggestions on the dash pad (hidden/undermount with no grill) and kick panel speakers (hidden/recess with no grill) and I don’t want to cut into the door panels. I would mount them flush under the dash and kick panels.
Thank you.



The reason for the rear 6"x9"'s in the rear is I like a full sound and didn't like the original dash pad with added kick panel speakers before.
As for components, I'd be interested in tweeters only in the dash pad, but don't know enough to select a certain brand and model.
Any suggestions?





I have 5in round JVC's in my kickpanels. You need another shallow magnet here too and you have to cut a hole in the plastic kickpanel and then you put the speaker cover over that.
Then I have Bose 301's in the rear.



This is the correct answer; the interior cabin of these cars is quite small, and if you have a good set of amplifier driven component speakers in the front, there is no need for rear full range speakers - if you also have a sub(s).
Since you are local to me, you are welcome to listen to my system any time you want to judge for yourself. I have:
- MTX 5 1/4" component set with the mid driver in the door and the tweeter in the dash
- 2 Rockford Fosgate 10" subs wired for 2 ohm load
- Rockford Fosgate 4 channel amp; 2 channels driving the front speakers at 4 ohms stereo and 2 channels bridged mono driving the subs at 2 ohms
I placed my mids in the doors because I found I liked the front soundstage better with them there as opposed to the kick panels. Wherever you place the mids, going with as big a driver as possible is better - in this case, if you can fit a 6 1/2" mid driver where you decide to put it, that would be better. I couldn't fit a 6 1/2" in the door, so I went with a 5 1/4" mid driver. Whatever you buy, you will also have to make sure that the depth of the driver will fit where you want to put it.
Don't waste your time or money on any 4x6 speaker, they are all terrible.
You can use your 6x9's in the rear until you add a sub.
Here is a decent 5 1/4" set in your price range:

It's been awhile Frank, I hope to see you driving your vette this year!!

Over 40 years ago I cut the fiberglass in the rear deck for 6"x9" and am stuck with them now so I'll stick with 6"x9" in the rear. I want as much of the rear compartment as I can therefore I was going to eliminate a sub based on space requirements.
If I add a sub I would need to maybe add another amp, which I already have but would need to find more room to mount it which may cause a problem.
I assume you have one amp for 2 Rockford Fosgate 10" subs and the MTX 5 1/4" component. Do you have a model number for the components?
I think I'm going to go with 6.5" in the door as I don't want to cut up the door panels. Any suggestion on model numbers?
If I'm mounting tweeters in the dash pads, I'll have to find a way to secure them to the 4"x6" openings.
I've got maybe 60 hours worth of work and maybe $1000.00 more in parts I need to purchase, but yes I hope to be out more this year as the Vette wasn't road worthy till late last summer.
I'd love to hear your system Bruce, but I'm trying to order the speakers in the next week for pick up in Niagara Falls NY first week of April.
I hope to have made a decision within a week.
Conclusion, it looks as though I'm going to be looking for 6.5" components, with matching tweeters? If so the budget is max $300.00 Canadian so that's $225.00 U.S.

If you are not planning on adding a sub, PLEASE seal off the rear of your 6x9's; not only protect them from the elements, but more importantly to improve the bass response. If not with some sort of enclosure, at the very least get a set of XTC foam speaker baffles.
If I add a sub I would need to maybe add another amp, which I already have but would need to find more room to mount it which may cause a problem.
You could use your 4 channel amp to run 4 speakers and a sub(s); the front and rear would be wired to the same 2 channels, and then the sub(s) on the other 2 channels. Your amp would need to be capable of running at 2 ohms, and your front/rear fader control would then be between the 4 speakers and the sub(s).
I assume you have one amp for 2 Rockford Fosgate 10" subs and the MTX 5 1/4" component. Do you have a model number for the components?
My 5 1/4" components are MTX Thunder series.
I think I'm going to go with 6.5" in the door as I don't want to cut up the door panels. Any suggestion on model numbers?
I'm confused! Are the front speakers going in the door or kickpanels?!!?

If I'm mounting tweeters in the dash pads, I'll have to find a way to secure them to the 4"x6" openings.
I mounted mine using metal straps that I bent into the proper shape to hold the tweeters; here is a pic that was taken laying on my back looking up at the passenger side tweeter:

Hope to see you out and about!!!

You are still welcome to come by anytime Frank!

If you are mounting them in the kickpanels, will you be mounting them behind the panels, or on the front of them? Either way, you may have to trim some of the metal of the birdcage to accommodate the driver's width, and you will need to very carefully figure out your maximum available installed depth. Mounting the drivers on the front of the panels may make it easier. You will also need to make the rear of the driver sealed off from the front for it to perform properly.
One other thing to consider with components, is where to mount the crossovers; they are not that big, so it's not really a problem, just something to consider. I mounted mine inside the #2 body mount cavity. Here is a pic with the passenger side crossover pulled out:

First off, thanks so much for the detailed reply with photos it sure helps.
There is a metal panel that covers the rear speakers (gas tank cover) but the ends are open and I've been wondering how to cover the rear 6x9's, the XTC foam speaker baffles are a good idea, thanks Bruce, I'll see if I can get a set.
You could use your 4 channel amp to run 4 speakers and a sub(s); the front and rear would be wired to the same 2 channels, and then the sub(s) on the other 2 channels. Your amp would need to be capable of running at 2 ohms, and your front/rear fader control would then be between the 4 speakers and the sub(s). I'm going to have to reread that several times to truly understand it, but as for now, I'm going subless.
My 5 1/4" components are MTX Thunder series. Would you happen to have a model number as I can't seem to find the ones you have?
I'm confused! Are the front speakers going in the door or kickpanels?!!? Recess into the kickpanel, so I'll assume 6"'s are too large?
I mounted mine using metal straps that I bent into the proper shape to hold the tweeters; Ok, I get it, the straps won't be hard to make.
You are still welcome to come by anytime Frank! I wouldn't mind dropping by your place one day, I'd like to see your place as I know a lot of magic has been created in your wonderful garage. I believe you're in Whitby/Oshawa area? Maybe Les will show me the way as he lives down around the corner from me now.
If you are mounting them in the kickpanels, will you be mounting them behind the panels.One other thing to consider with components, is where to mount the crossovers Behind the kickpanels, what size would be the largest and yes I can trim inside the kickpanel area. I forgot about the crossover, thanks. Thanks again Bruce.

Or buy Canadian which appears to be a better deal.

Thanks for the link, correct me if I'm wrong but they're not components?
