Hi!! I need replacement speakers for my 2003 Lexus SC430. Originals are Mark Levinson garbage stock, don't want to tear them out just to replace them with the same garbage...can you help me find replacements that will fit....they are 8 ohm and 16 ohm and only a depth of 3" on the doors....Need two 6x9 8 ohm and one 8" 16 ohm in the rear.
