Finally got around to finishing installing my components in my car.
Custom made speaker mounts because the original BOSE ones left a gaping hole if you just replace the speaker.
I'm realizing my GMAA ClassII line out adapter isn't meant for high frequency sound. It sounds bad at low volume. oh well guess I have an excuse to get a new HU.. darn.

Hmm... that's interesting. Any reason in particular you installed the tweeters down in the floor area, instead of in the dash? :confused:

Looks clean though; nice job. :cool:

Looks real nice. The dynamat I am sure will make it a lot quieter.

For the best imaging you want to have your speakers as far away from you as possible. Thats why companies like q-logic manufacture kickpanel enclosures

Plus, I am going to experiment with putting GPS and XM antennas where the current dash-mounted speakers are so they'll be hidden but still have a pretty good view of the sky. I'll let ya'll know how that works out when I get it it ;)

hmm... makes sense. I guess I just never thought of it like that.

For your antenna hiding idea, that sounds like it could work out well.... you may end up replacing the grates with some smoked plexiglass though, to increase the signal's throughput :m2:

This sounds like an awsome idea.... :D

For XM - I fear you will not be too happy with the results. We installed a Satellite Radio Antenna on the back deck of a 2005 Crown Victoria , which has a huge back glass, but the reception kept fading in and out. It may work for you, but there was nothing blocking the view, it just did not work well at all.

Now for GPS, you should have no problem at all!! GPS antennas work differently and do not receive as much information as Satellite Radios. Believe it or not, in my wife's PT Cruiser, the GPS antenna is actually under the plastic dash cover! It is totally hidden, no holes, no nothing and it works perfectly. Plastic does not interfere with the signal at all on GPS antennas.

Your doors look great as do your kick panels.

Really? What antenna was that using? I had the Delphi micro antenna that comes with a SkyFi2 car kit on my last truck, right in the center of the dashboard and velcroed in place. I never had any problems with reception at all. :confused:

Just a couple comments on the broad range of subjects being discussed here.

1. Having the speakers far away from you does not necessarily mean you will achieve the best imaging. The rule should be, put the speakers where you get the best imaging, if that's far away, then put them far away. Some of it has to do with the speakers dispursion pattern, range, power, etc. It depends on the speaker and the application.

2. The reason some XM antennas don't work well on the back deck as specified is because some are designed to use the metal they are mounted to as an extension of the antenna. If they don't have enough surface metal, they perform pretty bad. Some are designed where they don't have to be installed on metal. Others come with a small metal pad to place under them. Just look around and find one that meets your needs, there are plenty to choose from.

I feel that was the problem with the antenna we had, it required more metal than we could provide. The one I have on my boat came with a metal plate and it works perfect. It is mounted in fiberglass and does great. The only problem with the marine antennas is they are BIG!!

Very true. Don't go taking a hole saw to your car until you've played with different speaker positions and spent some quality time with a CD you're really familiar with.

JimmyJam, nice install by the way.

The first thing I noticed was the liberal use of Dynamat. TWO THUMBS UP!

The second things I noticed was the clean speaker mount and the nice flush install of the tweet.

Very nice. Well done.
