Audio Systems: pioneer system for my truck, cd player pioneer, watts rms

Question
Recently blew up stock speakers in truck. (97 f150 pickup). AFtermarket cd player, (jvc.....17 watt rms).
  Installed Pioneer A6780 (6x8 3 way speakers), in front. (to replace the blown stock ones).
 The pioneers buzz with lots of bass, (not LOTS like too much, but fairly loud with LOUDness on).
  I am thinking the jvc is too small for the speakers?  they're rated at 50 rms and 200 max.
 In either case, I've already ordered another pair of the a6780 speakers for the rear of the truck, and a DEH1600 (cheapo), cd player (pioneer), for it.  It (the cd player), is rated @ 50 watts rms x4.  I would 'assume' that this would take care of my lack of power problem?

Your thoughts. (always thought that running 'matched' componenets was better than mix'n match).  (at least that's what works in the home stereo setup).
Thanks for any thoughts/advice. etc.


Answer
Steve,
I've thought about this problem for a couple days, and I believe that the 'buzz' you're hearing is actually line noise combined with bass. Most likely when the speakers got installed a wire got pinched somewhere along the line, or the shielding on one of the power wires got scrapped off. A noise like this could also be caused by an improper grounding of the CD player. The LOUDness option on the deck just amplifies the buzzing noise. When you replace your CD player and put the new speakers in, I would recommend checking all the wiring leading to and from the deck, as well as the speakers. Most of the time loose or pinched wires are the culprits of all sorts of problems.

Also, running 'matched' components is highly recommended for any speakers that aren't your subwoofers, and if you have multiple subwoofers, they should all be the same brand. Amplifiers should be the same brand too, but sometimes that's not always possible. Mixing and matching is how most people build their stereos. Anyway I hope this gets you going in the right direction.

Best Of Luck,
Alan
