hey ben i don't have one or any literature, i did install them for a couple
years, but that was many moons ago.

if it does not have speaker outs then i bet it's an 8v preout unit [most are
2, some 4, higher-end, pre-out only stuff is usually 8v]. this may account
for the overdriving of the amp - does the amp have a line/rca input
selector? or the radio may be faulty. if the amp is set properly, and
everything is working correctly, you should get good sound, the 8v preout
will just mean the gains can be set relatively low on the amp. try taking
the signal processor thing out of the loop to determine if that's faulty.

it should be very easy to tell which is front and rear running preout to amp
and using the balance control - IIRC the clarions had a squareish
joystick-type button that controlled fade and balance, but i'm pretty rusty.
if you can't


IME used car stereo is either broken or about to break. it lives a tough
life in a very tough enviroment.
