Thought I would share my stereo install. 
Could not handle the Bose any longer. I went for a good system, not comp, but impressive, with room to grow. I added an Audio Control EQS after the Bose amp. This allowed me to tap off for my front speakers and also provides and out for a Sub. It also gives me EQ which I believe is mandatory in the FX. This eq was able to handle the Clarion preouts as well, but I found the extra boost of the Bose amp helps with the overall output signal. The Clarion is .33v which in minimal/pathetic. With the EQ preamp and postamp I can get to a 2-5v output to provide the main amp. Also, I cannot discern any additional noise between attaching prior to the bose or after it. I then go into a Elipse 85x4 amp. Two of the channels are for the fronts and the others are bridged for the Sub. I am using Focal 165KP speakers for the front. These are incredible speakers 8) . In the past I found focals a little fatigueing, but the new tweet on these are excellent. I like that edgyness that domes can't provide, but without the harshness. I am using a ADS 10" sub that I had from a previous car. This sub has great punch and sound quality, but does not go all that low. I am looking at the IDQ10. Any comments would be appreciated, these look good on paper and a .5cu box makes me smile. The rear speakers are intact and running off the bose amp for background fill. I had to remove the center channel speaker and hoped that this would be the system. Well, the sound stage level was too low. Typical of smaller tweeters with a 3' span to the midbass. Morel and Dynaudio do pretty good with this by having the tweeter extend much deeper, providing more vocals to be higher, on the dash. I ended up buying the rainbow center channel that 4tyson is using in his system. This is a nice speaker and pulls the soundstage back up and provides the center fill needed. This is run off the Bose amp. It does not require much power, and bose has the crossover on the low end already taken care of in the amp. I was able to adjust level between the focal and rainbow with the gain on my eq. BTW, the door speakers are 2ohm, these little cheapos in the dash are 4ohm. So they are easier replaced. I read some other posts on the spare and hold down. I bought a bolt about 1" long with the same thread as the sub/spare hold down and went through a 1/4" x18" round press board to hold the spare down. I then mounted my eq on this press board and made some stand offs from it up to another dupilicate board. I mounted my amp on top of this one. So, I basically have the electronics sitting inside the spare. This lets me hide it. The sub is currently in a box in the back, but if I go with a tiny box I think I could sit it behind the passengers seat. I need to get the SAT going. The tuner in our car is awefull, the cd seems to be fine though. So how does it sound? Fantastic, still some tuning, but I am now smiling
