Clipping the signal is what ruins speakers.
I do, recommend you using a subsonic filter. The amplifier you have may be equipped with one.
Where in Yadkin County are you located?
I know enough about electronics to be dangerous. By gain, do you mean input level? I guess that I can adjust that when I get the system setup, either on the bench or later when I get the car back from my body man.
The amp has a subsonic filter switch: off-15-30Hz. I assume I should use 30. It also has a crossover frequency adjustment (30-200Hz) and Bass EQ adjustment from 0 to +16dB.
This is going into my project car, a '64 TBird. It's a complete restoration. Nothing is in the car now except the steering column, and I'm rebuilding that after it's painted.
The head unit is a Custom AutoSound USA 630 than puts out 4 channels at 60watts each. I've got two 4" coaxial speakers mounted in the dash in place of the original 4x10. Crutchfiled had an open box special and I got two Retrosound 5x7 coaxials that have a shallow mounting depth, and those will fit inside the rear roof pillars, under the headliner.
I actually live in Forsyth County, on the western side near the Yadkin River. Are you familiar with this part of the country?
