Hey all i have not really been on here much in the past 12 months or so.
But hopefully i can add a little bit of light to your problem for the sound.
I installed 2 guys stereo's in their corrado's.
First install Setup consisted of:
Alpine 9856 + IPOD Control/Cable
Infinity Kappa 50.7cs
E-Audio 480Ab
2x Resonant Engineering RE8 (Custom Fibreglass enclosure, Left side hatch not using boot space)
Second corrado Setup consisted of:
Alpine 9887 +IPOD Control/Cable
Infinity reference 5.25" components
EAudio 280Ab
1x Polk Audio Momo 8" MM2084
Here is what i found with both systems, and things i did to make the front stage sound better
Firstly once the 5.25 are mounted, use some dacron and put piece approx 6"x6" behind the speaker and remount the door pocket/speaker pod back on to the door.
Re install door card. Mount the tweeters in the factory dash location. Have the tweeters aimed up at the window. Left side tweeter needs an extra 3 or 4 degrees towards the window so that both tweeters bounce of the window approx the same time. Also wire the Tweeters oposite to the woofers on the crossovers.
IE. Positive goes into positive of crossover and negative goes to negative of cross over.
Same applies to the woofer, This is where is becomes a little confusing to explain. But negative of crossover goes to positive of tweeter, and positive of crossover goes to negative of tweeter. I found this not only images better in the corrado (and the MK3 Golf) but becomes more smooth and all harshness dissapears.
Do this above and you should find a great deal difference in the sound in the front of the rado.
Now for the amp locations.
I mounted them on a board which was mounted on the left rear single fold down seat.
I have some pictures of the boot install in the dual RE8 setup, but none of the single 8" setup.
Either one of these setups you will enjoy.
However the first system with the Infinity Kappa 50.7cs where installed in the car running from the radio for approx 3 weeks.
This sounded really good with only the dacron mod and new speaker wiring from headunit to speakers (including crossover wires).
