I've upgraded all of the stereo components (deck, amps, subs, speakers) in my 382, but I feel like it's missing some high end sparkle and it's hard to hear the music when running. The 6x9 coax factory locations are very low (knee level or lower), so I was thinking about adding some component tweeters. I would probably run them off the crossover in parallel with each 6x9 of my 4 channel amp, the amp is rated down to 2 ohms x 4. Has anyone done anything like this and have any advice?
