That would be cool to see. All I know is that my sound system now sounds 15 times better than stock... it's not even a comparison. I had thought about getting a 5 channel amp to power the other speakers as well, but there is no way I need it.
I can hear my music loud and clear going down the highway at 70 mph with the top off and doors off.
That’s amazing. I was thinking I may too after testing out the result of this starting point. My deck can do 4x20 (55peak) so may not be necessary given your experience.
