Over the years I had my hands on a couple of Q475.1s, a single Q120.4, a Q275.2 and a Q175.2... I still have one of each and they are all installed in my Trans-Am...
Oh, and the Balanced Line Drivers are real, I own 4 of them. Also used in the above install. Proof:
Pictures of the Q475.1 (up top), Q275.2 (on the right) and the Q120.4 (on the left), this was during the build phase:
And in this pic you can see the balanced line inputs to the amps:
If you haven't noticed, I made sure the amps were given the honor they deserve in the install. They are raised up and displayed properly for the beasts that they are.
The last amp just couldn't fit anywhere up top, so it is underneath the sub box:
I ended up using the balanced line drivers for everything but the rear-fill amp. I would have prefered to only run standard RCAs for the Q475.1, but with it needing 4 line inputs and with it being the top amp it demanded the balanced line drivers for asthetics. I ended up modifying the cable for the Q475.1 to a y-cable so I could run it with a single balanced line driver at least.
Hmm, just had a thought... Does anyone know if the single line-output from the Q475.1 can be used as a single line-input?
If that were the case I am sure I could even have a single RCA made to match the asthetics and move the last balanced line driver off to the rear-fill amp.
For a layout, the system is broken down as follows:
Q120.4 Ch1+Ch2 - Front Tweeters - Active H701
Q275.2 Ch1+Ch2 - Front Midbass - Active H701
Q120.4 Ch3+Ch4 - Front Center Channel - Active H701 + Passive CDT xover
Q175.2 Ch1+Ch2 - Rear Fill - Active H701 + Passive CDT xover
Q475.1 - Running 2 ohm into subs - Active H701
The rest of the system is:
Alpine IVA-D900 headunit
Alpine HDA-5460 MP3 HDD unit
Alpine RUX-C700 Processor Controller
Alpine PXA-H701 Processor
Alpine NVE-852A Navigation
Alpine SEA-8081 Alarm w/8502 pager
Seas Neo Al Tweeters
I used to own 4 of Zeds last line, including a couple of Miniliths, a Duece and a Draconia (with both the Duece and Draconia being of the Burr-Brown versions)... Unfortunately, I did not have a vehicle install on the horizon to take advantage of them (even tho I did have a CDA-7949 w/PXA-H600 setup that would have been the perfect source for those in a pure SQ capacity), so I let them go to someone who was putting together a nice setup. I also sold off the CDA-7949/PXA-H600 setup so I wouldn't be tempted to buy more amps until I need them...
