i'd have to say this would be the best bet for a good sound because i found that the rear speakers do nothing but add a slight echo and have a slight delay beacause they are much further away then the rest of your speakers are from your ears, except i'm not all that convinced that you need the wicked cas pods. 5.25 speakers fit just fine and sound fantastic andyou don't have to spring the extra money for the podsha, i believe they are 3.5". a much better option would be to purchase a pod from wicked cas and install a 5.25" component set, 6.5" coaxial, or a 6.5" mid with a tweet elsewhere. what does the rest of your system consist of?
Just my 2 cents
