I need some help on setting up my stereo. It's a 1978 Lincoln Continental. The original 8-track was removed by the previous owner and he had installed a tape deck that was compatible with common ground wiring. I rewired the audio system and installed an Alpine CDA-9856 for my headunit.
The front door speakers are 6.5" Infinity Reference series with the rotating tweeter.
Amplifier is a Profile AP-600 that I had powering a pair of Infinity Reference 6x9s in a 1976 Buick Electra. They sounded very good in that car, and that audio is my benchmark for my Lincoln. I would like it to sound even better since the car is nicer.
The Lincoln had mounts in the rear for 5x7 speakers. I was not happy with the sound from the 5x7 speakers (I had Sonys and then tried Infinity Kappas) and wanted more bass like I had in the above mentioned Buick. I bought some adapter brackets that will allow you to install a 6x9 speaker in a 5x7 location (not sure about these really). I bought some Polk DB series 6x9s that sounded like crap, so I returned them and again went with Infinity speakers.
I was hoping I could get some suggestions on what to do. I would like some more bass, but the way the trunk is designed, I don't think a subwoofer would sound very good as there is a lot of metal and a gas tank in between the cabin and where the subwoofer box would sit. I do not think there is enough room for a free-air subwoofer that hangs from the package tray as the spare tire is in the way and even if I were to move it, I don't think there is enough width for even a small subwoofer.
This is the 5x7 mount with the adapter and the Polks installed. I returned those as they did not meet my expectations and compared to my Infinity Reference 6x9s that I had installed in my Electra, they could not play at my listening level with the same amount of bass without bad distortion--The Infinity Kappa 6x9s that I had now can play at higher levels with a good amount of bass. The 24 gallon gas tank sits under that shelf for the spare tire...so I was thinking that putting a box into the trunk might not sound very loud in the cabin...I would rather keep the sound on the inside of the car as much as is possible.
I have mixed feelings about these adapter brackets...The speakers now sit about an inch and a half lower than a 5x7 would and are not sealed. I plan to seal them as I imagine there is some negative/positive air pressure issues there, especially with the lowend (acoustic short circuit as I have read).
I will cut into the package tray and enlarge the openings if I have to...that is if it would make a real noticeable difference, otherwise I will just seal them and see how that sounds.
Are Infinity Kappa speakers worth the price? Fry's charges $190 with tax for them (I can get them for $100 less online but I wanted to hear them first.)
It was recommended on another forum that I look at Tang Band 6x9 woofers...are those worth it? I would have 2 of those in the back and then have to buy some sort of component set I guess.
