i was most likely going to get the MB Quart Premium components for my grand cherokee. i was listening to them at Tweeter and the guy(s) there said to get a JL 300/4 amp to power just those. he was saying it would be like 75 watts to each speaker in the set (if that makes sense). is this the right thing to do? or should i get a 300/2 amp? he said they had done that install in a few cars like mine and it sounded great. any input would be greatly appreciated, thanks in advance! p.s.- are there better options than the Premiums for around the same price? thanks!
