I got a 1990 jeep cherokee and i need help re-installing the tweeters because i had an 90 watt am that aint working rite now and i tested the tweeters on my sub amp and they worked but i can't use my sub amp cause it is only a 2oo watt amp and i have 2 10" subs so i can't use it i just want to go straight to my head unit because i really need to listen to some music when i drive.
