I'm enduring what I thought would be a great system but which has turned into a study in teeth-grinding frustration.
As listed in my profile, I'm driving a 2002 Civic Si and currently have:
- an Alpine 9827 head unit, which I despise and already have a Blaupunkt Casablanca MP54 ready for replacement purposes;
- PPI PCX4125 (4 X 125W @ 4Ohms) amp;
- two pairs MB Quart PCE216 component 6.5 speakers mounted coax in the doors and back side panels.
- I also have an Infinity Basslink powered sub that will be installed with the new head unit, but for the moment it's just the four MB Quarts.
I listen almost exclusively to rock - as in heavily-distorted 70s-80s guitar-oriented hard rock, and never, ever, run rap through my circuitry. Unfortunately I don't know diddly about tuning up a car audio system, and the idiots who installed the system at [rhymes with "Workit Sh*tty,"] along with most of the car audio world, are apparently lost when they try to dial in anything that's not rap. So I had to tune it up myself, in half-arsed fashion, after the install.
The PCX4125 / PCE216 combination is supposed to be an amp/speaker marriage made in heaven [i bought it largely on the basis of this rave review,] but I'm fairly certain that I've damaged the speakers. At higher volumes there's a whole lot of mid and high freq distortion that has nothing to do with the natural distortion of rock guitar, and it's gotten progressively worse since the install.
I hasten to add that I haven't been irresponsibly cranking the thing to max heedless of the consequences, just listening at a level I consider adequate for rock. From the very beginning the volume level and punch factor were vastly disappointing.
Obviously there's only so much bass you're going to get out of 6.5" speakers and the Infinity sub will take care of that once it's in, but bass is not the point. I jumped into a friend's car a couple months back and listened to his comparatively cheap system - I think his 6.5 speakers are a pair of mid-level Infinitys - and I was emerald-green with envy. He listens to the same kind of music I do (I distinctly remember the Rush "Moving Pictures" disc as a reference,) and his mids and highs were so powerful and crystal-clear I almost had to get out of the vehicle.
I have a hard time believing that MB Quart's top-of-the-line 6.5 components can be so lame at reproducing rock - I'm assuming most of the problem has to do with my setup job, but even so, with a head unit/amp combination with as clean distortion specs as what I'm using, should this kind of nonsense be happening?
Four questions - please pick one (or more) and sound off:
1. Given that I hear varying degress of buzzing and static whenever I get close to high volume- or just whenever a certain instrument hits a certain peak at a certain frequency - can I assume my existing speakers are fried? If so, is there anything that can be done to refurbish them short of replacing them altogether? Is the tweeter the only part that reproduces highs, or does fried highs mean the whole driver is damaged?
2. Does anybody know of a speaker manufacturer with a 6.5" mid-high speaker system that's built like an M1 Abrams tank and is capable of handling 125 watts of heavily-distorted rock guitar* on a more or less continuous basis with ease? At this point I think I'd be willing to go up to $600 or so if such an animal actually existed;
3. If there's anybody reading this from Southern California, can you recommend a good, reputable car audio installer who doesn't mind installing stuff without selling components and who is into rock exclusively and is therefore fully competent to tune up a system for optimum performance once the install is complete?
4. I bought a Dynamat Xtreme bulk pack but never had it installed because the Workit Sh*tty guys wanted something like $200 for the labor. Will that stuff make any significant improvement in the side and door panel drivers, or is it just for rattle elimination?
Thanks in advance for any suggestions, and pardon my running l o n g - they don't have brevity on my planet...
