C5 Factory HU & some upgraded toys... Good evening all! I'm a newbie to the forum.You have been very informative throughout many threads that I've disovered and I'd like your thoughts on the following: I've read the thread on C6 and cleansweep but my questions are... 1)Do I need a cleansweep for a 99' C5 under the following setup? -Factory Bose HU in 99' vert/ keeping CD changer in trunk/new 4 channel amp/new component speakers/stealthsub/remote for sub/JL cleansweep? 2)Also your comments and/or suggestions/advice on the following components or others you could reccomend -Front speakers: Focal 165vr or 165v1 or infinity Kappas OR ? - 4 Ch-amp: Kenwood KZCX4R (digital) or JL 300/4 or Exonic 750 - Rear speakers: running off HU or disconnect? -Sub: 8/10/12inch 3) Is SQ degrated by keeping OEM HU. Or is a better solution a aftermarket HU (No need for cleensweep) Thanks
