Need an o-scope for testing 12V (car audio) amplifiers

Hi,
New here to the forum and have questions.

I am looking by a 'scope to simply view the output wave-forms from 12V car audio amps.  I have never dealt w/ 'scopes before, but I'm guessing I only need a basic model...maybe even a PC based one.

I need a scope to fit my needs:

-Freq range will be ~20hz to 20khz. (audible)
-Output voltage from amps should be no more than +/-100vac
-Need to simply view wave-form
-If possible, need to be able measure THD and/or THD+N at 0.5%(min) to 10%(max).  I will be looking for clipping.

I'm guessing that w/ a PC based scope, I could use attenuated probes to allow for +/- 100vac.  But other than that, I'm lost.

Can someone please recommend a scope?

Thank you for any help you can give.
