Question about Alpine SPX-17 PRO Car Component System
I have a pair of alpine spx-17pro's in my front door panels, being fed 100 watts RMS from my Alpine PDX-4.100 amp. Just recently I noticed a rattling sound coming from my speakers... so I opened up the panel and look closer and found that around the center cone of the speaker there is a black plastic ring: kind of like on the border of the woofer and the cone. And when the sound is really kicking the plastic ring vibrates against the cone causing the rattling. Now I don't know why this is happening as I never noticed it before. Is it a blown speaker or might it be vibrations from the sub I have in the car? I talked to an audio guy and he said i might have gained the amp that was feeding them improperly therefor blowing my speakers, but I checked the gains and they are all stock gained (nominal). Thank you a head of time for all the great advice, Terrence

SOURCE: alpine amp and subs questions
it will depend on how you use the 2 alpine subs,, do you know what there individual impedance is [ ohms ] and how you intend on wiring them,,,in series, in parallel, in any case you must maintain the min load in order to load the amplifier properly,,,otherwise the amplifier will operate improperly and allow DC [ direct current ] to pass and fry your subs...so what I really need is more in formation

SOURCE: Blown fuses
This is a sign the you have poor voltage regulation. Which may mean that you are taxing the electrical system of your vehicle. I would suggest you adding a secondary electrical supply for you audio system. This can be done by adding an extra alternator and voltage regulator and battery supply. This will allow you to drive your audio system without having it (power supply) split between the vehicle and the audio system. The fact is your system is drawing to much current for the unit and your vehicle. You are blowing the 20-amp fuses which means the the amp is creating a currnet draw which is past the rated value of the fuses, which if done too many times could damage the power amp components in the unit. I would also check the ohmage reating on the speakers connect to the unit since you may have the wrong impedance which may also cause excessive current draw and actuate some sort of overcurrent protection.

mostly because the subs in the back are probley using more amps than the ones in the front in the front should be used mostly for vocals and your bass in the trun so maybe trying to unhook the ones in the front from the sub and just leave then hooked up to the cd player where you can hear the vocals really good and leave your subs in the back hooked up to the amp
