Fool Everybody. Stereo looks stock, sounds great. (Page 12/19)

The passenger side is not a problem when it comes to depth. I ran into issues with the drivers side. Nothing that a rotozip bit could not fix though. I also had to move the driver side large speaker hole more to the center. Well worth the time now that I have a much better sounding stereo.

Fierosound, Just curious, did you try both lengths of the tube? 3/4 cut off and 2 inch cut off??

Which length sounded better??

The 2" cut is for when the speaker has been broken in. when I made my origional calculations I went off the factory specs. After a couple of months I was unhappy with a resonance I was getting so I pulled the speaker and used a test jig to measure the speakers QTS and found it had increased by .1 from getting "broken in" This recalculation caused me to rethink the speaker and adding a little more poly to get closer to the max volume makeup that poky can do and cutting the port a tad shorter to lower the frequency. I calculated that 1.75 would be ideal, found that 2 inches sounded better.

it is NOT a huge difference. and I used it mostly to get rid of a boomy frequency peak.

I started with the 3/4" cut as Tim suggested, and have now cut it off another 1-1/4" to make it a 2" reduction in the port tube length. As Tim said, the difference is not 'night and day', but there's less boominess. I changed the X-over to a lower poit to reduce the mid-bass from the subwoofer. I think it sounds better with 2 inches cut off the port tube.

I wanted to say thank you again. I was so happy with my stereo, I "ripped" up my mothers Mera, added sound deadening under the carpet and on the firewall, installed new front and rear speakers and the Tang Band sub. It sounds great and she is happy.

Where is a good place to mount the crossovers for the 5.25 component speakers...been looking at my car and I can't seem to find a good secure place to mount them. Those who have mounted them, what did you do?

i plan on using my monsoon 10 speaker amp as my crossover and some 2 way speakers. just separate the tweet from the speaker on a 2 way speaker and run the tweet lines from the amp to the tweets and the mids channel to the actual speaker. and for the woofer, just run that into the sub itself. im going to hafa be creative on getting the slider bar to work with this.

These are "install and forget" crossovers that don't need adjusting (like mine)?

Passenger side - I mounted it on top of the heater box with double-backed foam tape.
Drivers side - just foam taped them to the firewall insulation close to the speaker.

If you had adjustable ones, you'd have to pull the speakers each time you wanted to tweak them. In that case, you may want to mount them in a different location.

I'm looking at the Infinity reference which are 4 ohm and are install and forget. I want to mount the crossovers in a secure place as I plan on taking the car to a race track from time to time and want to make sure that they are securely fastened. Thinking of mouting them to the plastic piece that runs along side of the center console that is covered by the carpet (where the stock amp is located on performance sound equipped cars). What do you guys think? Is this o.k or do they need ventalation?

The installation instructions should tell you whether they need ventilation or not. They don't generate the heat that the sub amp would, so I think they should be OK there.
