I getting ready to replace the stock kick panel speakers. I'm checking to see if the HK amp wires are already crossed over for the woofer and tweeters. I'm replaceing them with the rockford p152s, 5.25 woofer and 2 .5 tweeters. So I'm check to see if I need to use the rockford crossover or plug an play with the factory wireing.
