I have a Question about the head unit. Does anyone know if the stock radio is equipt with RCA inputs in the back. I am wanting to hook up some subs and dont want to replace the stock head unit. If not, is there a harness that you can purchase that wires into the stock harness? Any input helps.

Thanks, Eric

There are a lot of factory systems that have this problem (the popping/rattling). The basic issue with stock speakers is that, in new vics, the can handle more RMS (continuous power) than older vics, BUT they have a lot shallower cone travel.

In other words, your speakers are handleing the power with no problem, but the cones are "bottoming out." That's why there's not a lot of distortion, but the "pop/bump."

Well I dont have the premium set up, but I did replace all of the speaker with nice coax's, as well as added 4 tweeters and two 8 inch woofers (ask me where I put those lol). I've noticed some rattling myself, on the passenger side, but found it was actually the seat belt cloth beating against the door. Simple fix there ; )

I have the Boston 9 speaker on a 09. I have noticed rattling when I turn the bass up, but usually i have it on about 25-30 when I'm driving alone, so the music pretty much drowns it out. I might just check the passenger side seat belt lol...

I have noticed that from outside the vehicle you can hear the tailgate rattling to the beat. I reckon most cars with a tailgate are gonna rattle if you put a sub woofer in them. From the inside it sounds like the plastic interior in the back (around the sub) is rattling too. I guess a bit of double sided tape might fix that in certain places. When I have the time I will do some investigating and see if the rattles can be fixed, but like I said it only happens with the bass at 7-9 and at high volume I can't hear anything...lol

That said, I change the bass setting for each CD, cause sometimes I find that you get a much clearer bassline/kick etc by dropping the bass to a 6/7, and others you can crank it up to 8. Now when you get a song like 'Warp' by the bloody beetroots (if you like techno and havent heard it, check it out), you are gonna get rattle but I think its a fair trade off! :)

Good place to check: if you have an aftermarket license plate cover over your plate, you can get a lot of rattle from those. I know I do lol.

I was told that the 6X9 standard speakers are decent quality three way. Mine play just fine even at fairly loud volume. Remember too, CD's are not all alike. Some are recorded with great equipment and some are not. I would imagine that if you play a standard FM station real loud you would get a lot more distortion cause you are actually amplifying all the normal distortion inherent in AM and FM transmissions. They are very dirty. I am an audiophile and own a top notch dual monoblock amp and dynamic enhancer pushed through Infinity RS3B speakers at 200watts per channel/4ohms. So I know what a high end two channel playback sounds like. I am not going to change out my Compass system for a high end one because at speed, the noise of the car detracts from the sound anyway no matter what level of system you install. It's a car, not your living room.:D

Well everything and I mean everything has a resonant frequency. Which means when it matches the physical item and the amplitude is sufficient it will vibrate/resonate to that frequency. This could be glass metal panels etc.

You may have to as mentioned turn down the bass boost and/or tune with an equalizer to nullify the resonate frequency.

If you or better still a passenger a can identify the panel or part virating. You may be able to tighten or make some change to change it.
