Hey Guys. Here's a couple of quick snapshots of my recent stereo install. The woofers in the pic are JL Audio 10IB4 FreeAirs and the 6x9s in the rear deck are Boston Acoustics RX97. The Amp is an Alpine V12.


I also installed Boston's FS60s in the doors. They're a 6" woofer/1" tweeter component set, and I didn't really want to put the tweeters inside the doors as they would "fire" down at the knees. So I surface mounted them on the door trim opposite the mirrors. The problem is that just simply surface mounting them with the surface mount cups that Boston includes would have them firing right into the dash (the door trim anles down quite a bit). I needed to angle them up, but the angled cups were flush-mount, and I don't think there's enough room behind the door plastic to flush mount.

So I ended up using the angled flush-mount cups, but mounted them in another "cup" so I could surface mount them and double-sided tape them to the door trim. Here's a pic of what I'm talking about:


The problem was finding a "cup" of the right size to use with the angled flush mount cups. I went digging in the kitchen looking at various caps, and found that a "Bacos" cap fir pretty nicely! So off to the store to get a couple new bottles of Bacos, spray painted the lids black, and voila: angled flush mount speaker cups!

However I'm not really thrilled at how they came out. Does anybody else have any great ideas on how to mount the tweeters there? They sound really nice where they are, but the Bacos caps are a little cheesy.

Looks nice! I wish my sub amp would fit there.:^( How do you like the sound of the JL's? I have never heard a free air setup, but am about to jump in w/ both feet.

Hey Ron,
Go to your local Audio Shop. They may have something of what you are looking for. If I get a chance, I will email you a pic of what I did. I had mine dyed by a Guy who works at SEM in Charlotte [img]2.gif[/img] [img]1.gif[/img]

ron, the boston proseries 6.5 comes with three different tweeter mounting kits,maybe someone didn't use their angle mounts, they're perfect for that spot, also where did you put your crossover boxes?

Hi Peter. I was a bit apprehensive about free-airs as well, but have been very happy with how they came out. They hit nice and clean. IMHO they take more power to make the same bass, so I run the gain a little higher and that pretty much takes care of it. A friend of mine has a test CD that contains lots of tracks of single frequencies. The JLs basically have no output under 20Hz, but by 32Hz are at nearly full response.

I do recommend that you get at least two of them. I don't think that one would be able to make one hit hard enough. The biggest advantage is the trunk space, the biggest disadvantage is the cost -- the JLs were $130 each+tax.

Ron -- I'd love to see some pics! Send them to me and I'll post them here if you like. Also there's only three high-end car audio shops in Lexington, and none had any tips.

HEY now we're talking! Anybody out here have the ProSeries? I'll also see if I can contact Boston directly.

I put the crossover boxes under the dash. I used double-sided tape and stuck them to the nearest flat surface. The driver's side crossover is located in the driver's footwell beneath the fusebox, and the passenger's side is in about the same relative location.

Yup, ordered mine last night, was able to needle 'em down to $201.16 including tax for the pair! I have a choice to hook them up; either 75 watts/per side, or paralel them to 600/ 1. How many watts are you pumping them up with?

I don't really know. The amp is rated for 300W max, 100W continuous but I'm no where near that since I've got the amp gain set to only about 25%! I plan on upping the gain after I fix a noise problem (my flame-thrower switch radiates big time). Assuming the 75x2 was max power, I would think it would be enough but it will be close. Unless you're saying 75x2 rms, and then you've got PLENTY.

My crossover boxes are inside the door, above the speakers. I mean inside the door too

hi Ron,
That is rated rms. How is this logic? The amp is called a vortex by planet audio, and on it's "birth certificate", it says:
305 x2 into 2 ohm,
154 x2 into 4 ohm,
610 x1 into 4 ohm.
I am assuming that by interpolation, it means 75 x2 into 8 ohm (the JL's are 8 0hm). The amp is a real beast by my standards, it weighs 20 lbs! I stole it on ebay for $112 to the door, nearly NIB. They retail for over $450, with an msrp of 839. Anyway, my question to those in the know: Hook it up parallel to suck up some of that 600 watts, or just leave it one speaker to a side and use my (assumed) 75/side?

I cant wait for my trunk kit!

I'd go ahead and do them in parallel so you get 4 ohms. I'm assuming that those subs can handle quite a bit at that price. If those are rms ratings, you need your subs to handle 300 rms each, which it seems they do, yes? Get the most power out of it, you can always tune it down a bit you know. Nice subs by the way guys, wish I could get some. =( I'm just gonna have one 10 or 12 HX2 in the trunk and 2 6.5" subs in the rear doors. Good luck
