Hi, I'm new here and hope you can give me some advice. I just bought some JBL Power Series P953 6x9 3-way speakers for the rear of my car and JBL Power P552 5-1/4 2-way speakers for my front doors. They are currently being shipped to my house so I have not installed them. I will be running these off an Alpine 9885 HU, first should I get an amp, if so any suggestions? Also does anyone have any opinions of these speakers? Thanks for the help.
