Hey guys i just recieved two pairs of infinity reference 6022i car speakers for my bday, they are both 6 1/2, this will fit my 00 tl right?. I also have two 12 inch type e in a box waiting to be installed. I want the best sound quality from these speakers and i was wondering if i should hook them up with a 4-channel amp, i think i still have a 600 watt rockford amp from like 4 years ago, would this be a good idea? Anyone have these speakers? if so can you give a little input. Im just looking to have my car sound awesome. Oh and i have a dual single din dvd player as my headunit. Thanks for the info ahead of time
