Default DIY Sail Panel Mod for your aftermarket tweets

Well it's been awhile since I've posted on here. Just have too many hobbies with audio being my top priority. Alot would consider me an audiophile as I've ventured for many years with different speakers/components/high-end cables and so forth.

Anyway, enough side tracking. I found the stock tweeter location in my GT Cruiser to be horrible. It faces upward torward the windshield and really creates an emphasis on those high-frequencies, making it sound harsh (to my ears).

I purchased some Alpine Type S components temporarily while I was on the lookout for components I REALLY wanted - Polk Audio SR6500's

Here's a link to them, btw they're discontinued - Polk Audio - SR Series - Mobile Speakers

Well, prior to installing the Alpine's I thought I'd modify my sail panel to custom fit my tweeters for much better placement. Afterall, proper amplification+DSP/tuning/time alignment+placement are all important things to consider in an attempt to achieve sound quality in a car system.

The pics speak louder than words, and I highly suggest doing this than replacing the stock tweeters with aftermarket ones and utilizing the same location.

In the future, I plan to run an active-crossover for better tuning as well as upgrading my sub+sub amp and bi-amping the SR components.

Enjoy!

Here I pulled out the panels and used a hole-saw to drill holes through them. Since the panels are in no way flat (resulting in the tweeter sticking out), I thought I'd mod them.

You'll see one of them sanded down



Here, I played around a bit with angling the tweeter mount. Soon as I got the angle I wanted from where I'd be sitting, I glued a popsicle stick in place.



Here are both panels with tweeter mounts glued on.

Next up, the bondo!



After the very first application of bondo, sanded down.



Both sanded down and carved somewhat to the shape I want.

This is when I start using the automotive glaze to fill in the small imperfections. You'll notice it's darker than bondo, and it's much easier to work with.



First coat of primer applied!



Sanded down smooth for some more automotive glaze and another coat of primer.



I want to say this is the 6th coat of primer. It was primer+sand+automotive glaze+sand then primer again.

Very first coat of paint. Wanted to see how the finish would come out. It was too glossy for me and stuck out like a sore thumb in my vehicle.



This next one is after 2 coats of paint and 2-3 layers of paint (done from afar) to create a 'textured' finish. I wanted the sail panels to blend back in as much as possible with the rest of the interior.



Here it is installed back into the vehicle!

Keep in mind, I did this all over a month ago. Since then, I scored on a pair of SR6500's but without stock tweeters. Fortunately though, Vifa being the manufacturer for the SR component tweeter I picked up a Vifa ring radiator tweeter from Madisound.com

It blends in perfectly utilizing the SR crossover and is the recommended 'perfect' replacement.

I also fixed the panels a bit by finding and fixing any tiny imperfections as well as applying another 2 coats of paint. Looks much better now than it did in that last pic (and the one shown here)

Here are the Vifa tweeters compared to the Alpine's



And the SR6500's themselves

Here's the HU



All wiring/installation is done by me. Was rather fun, something different than the usual high-end home audio I play around with

Thanks

I still need to play with the angle a bit because the Vifa tweeters I installed (in conjunction with the SR setup) are non-swiveling.

However, it still sounds great. I'm still playing around alot with my time alignment settings but so far I have exceptional imaging. Vocals/instruments are coming from just above the dash at ear level (even though the SR woofers are in the stock location). Soundstage is wider than the interior of the car itself, it's great.

Need to mess with the time alignment on my subwoofer though. It's in the trunk, and after some time I tuned it to where it sounds like it's right behind you. It's progress, but not yet done. I need to adjust the x-o so it doesn't come off as directional. In some songs though, you can't even LOCATE the sub since everything blends in so well.

I'm about SQ, not SPL

Some would argue that the Polk SR components are among the best money can buy!

A guy on my other forum uses Polk SR's and has won several statewide+national awards for best SQ or SQL (Mecca).

I am thinking of Polk's when I get some cash to upgrade the speakers. Won't be that high end as the MR's, but still better then what I currently have (Stock)
