I ordered a new vehicle with radio provisions only (No stereo) it comes with speakers, wiring harness, and antenna. I decided I will go with an Alpine system and for starters will just get the head unit which I have picked out. It will be the Alpine ida-X303 and I will play it through the factory speakers for now. Then I will add the Alpins SPS-600 speakers. http://www.bestbuy.com/site/Alpine ...Deck/9212318.p?id=1218059946001&skuId=9212318 http://www.bestbuy.com/site/Alpine ...air)/8699429.p?id=1199494646605&skuId=8699429 Do I NEED an AMP and Sub? I am NOT into loud music at all. I like crisp clear sound and not BASS. I listen to Classic Rock, Classical, and Jazz, (I'm 48). Pretty much everything that is good, No bublegum pop, rap, or hip hop. Do you think a head unit and good speakers is enough for my needs?
