View Full Version : all 4 speakers blow at the same time?

ok, when i bought my car it came with pioneer 4x6's in the dash and 6x9's in the rear sail panels.......the previous owner had a small system, nothin crazy so i doubt they were driven that hard. I've had the car for about 2 years now and the speakers have always worked fine, until a few weeks ago I was in town listening to my music at a moderate bumping level (loud, but not "oh my god" loud) and all of a sudden the 4x6's started making a scratching, scraping buzzing noise but only when bass hits (or midbass, they're 4x6's) so now I can't play it that loud before they start crappin out again. At lower volumes they sound fine and you wouldn't know they were screwed up.

However, I recently noticed that my HU (pioneer 4600mp) gets really hot (like it almost hurts to touch the inside when you fold down the faceplate) it also heats my entire console up where after a while its uncomfortable to rest you knee on it. Could the HU heating up be causing the speakers to crap out?they worked fine with my jvc HU for 1.5yrs, and worked fine with this HU since october '04. It's weird because they just crapped out all of a sudden at the same time.

p.s i recently bought 5.25 comps and i just wanted to make sure the HU wouldn't screw them up to b4 i install them..........

pps, sorry for the long post, all help is greatly appreciated!!

I'm no pro by any stretch....
but from what I know i'll offer my $0.02 =)
if it's heating up that much, maybe theres a problem with the h/u's amp?
if there was a problem with the h/u amp, that might explain the strange performance of your speakers

but my subs play fine. Would that disprove it???

no, if anything it would make my suggestion even more plausible.....
(assuming your sub amp is getting signal from one of your rca outputs)
if your subs arent distorting badly like your speakers, and your speakers play just fine at a low level...... maybe the h/u's internal amp is overheating and clipping?
hopefully somebody more knowledgable will come along and help you =)
just my $0.02 - hopefully it helps a little at least

it is possible that the internal amp is crapping out in your head unit
