Speakers rattling
Hi, I recently replaced my front 3.5"s with some Infinitys because my stock ones were blown. After installing those, my rear 6.5"s (Pioneer) started producing a high rumbling/rattle noise if you will. I'm hearing it from the tweeter area only, as there are no holes or rips in the area between the "woofer" and the housing. Oh, and also, I installed some bass blockers on the fronts too. Now I'm wondering if this is a coincidence that my speakers started acting up after I installed the new ones or if there's something else to it. I'm running a Jensen CD4010K HU. I'll get the specs of the speakers if you guys want. Could it be that the power is rerouted or...something? Sorry, you can tell I don't know anything. Thanks

Re: Speakers rattling (NuRon)
Yes it is a coincident, installing new speakers in the front should have no effect on the rear speakers.
However, if the HU you have, "Jensen CD4010K " is a cheap entry level HU it may only have a 2ch amp in it, split between front and rear with a post amp fader, in this case installing higher power, less efficient speakers in the front would have an effect, but only because you can now hear a problem that was there all the time or because now you have to turn the volume up more to get the same output as you did before, resulting in clipping the HUs internal amp, although you should hear that on both sets of speakers.
A speaker does not have to look damaged to have a problem, a common cause of speaker "rattle" is a separated VC, [voice coil] it would sound like it was comming from the tweeter.
To test for this remove speaker hold it, [by magnet] up to your ear with one hand, [pointed towards your ear] give the back of the magnet a sharp blow with other hand, listen for rattle.
