the compass module is in the trunk and the sub would be far enough away from the PCM in the pass kick Panel

No 93 got TC, EBCM.

good call..... the 93 has applied braking for TC, instead of the timing retard

I got carried away on the letters

Im not sure putting the midranges under the HU would be a good idea from a soundquality standpoint. You will have a huge difference in phase, and they will sound muffled, with the passenger side being worse than the driver'* side

All good points you guys brought up...

I thought if you could put a single 8" up front, on a bandpass from ~ 50 to 120Hz, it would help things blend better. Back behind the radio seems like the perfect spot in the Bonneville. There looks like plenty of room to build something back there, but there are a couple obstacles... It'd be pretty simple to modify or maybe just junk that directional vent and let the heat flow around the sides of the box. Also building something that you don't have to take off the dash to maneuver in and out.

94bonnyV - how would I go about shielding? I will use fiberglass so is there something I can spray on the inside of the box? I have no idea... thanks.

One method is to use a 'bucking magnet'. the process involves attaching a magnet to the back of your subwoofer driver so that the magnets would repel each other (++ or --) this is done with some kid of epoxy... you should research a good one-- im not sure.

there is also some materials available for emf shielding, i've never shielded a sub, but it seems like it should work the same. do some googling and see what you come up with

That'* a pretty neat idea, definitely original! I'm saving that area for electronic mods and my amp, though

I really don't see EMF being a huge problem. In fact, I bet it probably wouldn't effect anything. If I were you, I wouldn't worry about it. And in respect to the compass, that module is in your trunk (even though the display is in the dash )

Good luck with it!

IF your going to do this, there is a certain way it should be done. I do think it can sound good and be original but u will have to have something that plays low say maybe about 100 hurtz and below and even then u will get some phase varience but u can get rid of it with an eq. just be sure to choose a speaker that can play that low and cross it over right

definitely. i was just trying to find a way to help out the very bottom end of the midrange to blend with the sub. With 5.25" components it'* tough even with good crossovers to get trunk bass sounding like it'* coming from up front... Omni-directional my a**...

I had 6.5 components in fiberglass kicks and 1 12" sealed in the trunk of my other car and it was still quite a trick. I ended up crossing the midranges at 80Hz 12db/octave, and the sub at 85Hz, 24db/octave and it came out alright. That was a real budget system and I chose to go with no rear fill which hurt the midbass response a lot. This time I am definitely using 4 channels

Which reminds me, I really like these Diamond Audio M6'* I saw. They seem like a great deal. The crossover has an 8ohm rear fill output so your rears are automatically blended at -3db, and it doesn't adversely affect the impedence the amp gets. I love things that make life easier...

www.adireaudio.com Check out the koda 6 and the koda 8s. The kodas are only 6s yet they can still accurately play on down to 70 hurtz, without any distortion, theyre pricey sure but if you build a good enclosure for them, such as kick panels, then they can sound good. the only drawback is you might want to put them in a big enclosure but if ur creative, you can think of something
