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

Question
97 f150 pickup.  Had/has (for now), a jvc in dash cd player. 17 watts rms.  Recently blew up stock door speakers.  (think they're only rated at like 2-4 watts),  Sounded good till them popped........anyway. Purchased some pioneer A6780 6x8 3 way speakers.  RAted @ 50 rms, 200 watt max.  I now have a buzz in (mostly in right side), at fairly loud bass levels in that speaker.  Is it possible that when the stock speaker popped that the right side of the cd player got a little messed up?   
 In either case, I ordered another set of same pioneer a6780 speakers for the rear of the truck, (so it's a matched setup), and ordered a DEH 1600 pioneer cd player (am/fm).  It's rated at 50 watt rms. x 4.
  I can only hope/assume that this would sound fairly decent with the semi matched speakers?
  Curious your thoughts on the ordeal.
(wish I could spend more for GOOD/quality speakers/head unit, but racing season is over).......

thanks in advance, Steve

Answer
It is remotely possible that the deck is the problem.

More likely it is the speaker or the door panel that is causing it (if not the deck).
However, it is also possible that you are driving the deck into distorion (trying to push these newer speakers that would seemingly be able to 'take' it) and that this is what you are hearing (speakers clipping due to the decks' power limits).

ANY speaker at any price can be damaged more easily from too LITTLE of a power amplifier (external OR onboard the deck)for this very reason.

As to the quality (these days), Kenwood/Pioneer/JVC/AIWA or what I call 'middle of the road' gear is, in fact, quite tolerable to most peoples' ears.
So do not sell it so short on quality until it is all installed! ;)

If you want, you might try temporarily swapping the leads at the deck for left and right channels to see if it is the deck or the speaker/door that is creating the noise.
If it then still has buzzing in the right channel..it is NOT the deck (check wiring connections for integrity and secureness - esp between the speaker leads and the frame of the door, as the wires that extend from the terminals to the speaker itself may be hitting metal and grounding out only when the speaker moves enough to cause this at higher volume levels). This would be rare, but it can occur.


I hope this helps you.
SCCA is over here (in Missouri, USA) too, for the year :(

Let me know if you need more assistance.
