Help with aftermarket stereo tuning!!!
I recently put an Alpine 9835 in my XB ( I made a post about it saying I love it!). So I decided to upgrade my speakers. I bought the Infinity Kappa Perfect component set. I had to buy spacers to put in the door so the window didn't hit the magnet. I put the tweeters in the dash (put them in the cover that covers the stock speakers in the dash). I put the crossovers in the dash behind the head unit (tons of room back there!). So then I fired it up and it sounded great! After about 10 minutes of listening at high volume I noticed that the tweeters were getting a little bit of static. But only at high volume. I tried messing with the "user eq" and the crossover on the alpine head unit, but I dont really know what I am doing and nothing made it sound better and make the static go away. I changed the crossovers that came with the infinity kit to -4db (lowest they go). I am not using the factory wire, I ran all new wire the the crossover from the head unit and from the crossover to the tweets and door speakers. Anyone have any suggestions!?!?! The RMS on the kappa perfect set is 100, and the alpine is only putting out 45 (I think), so I really doubt they are blown, but that is kinda what the sound (static) resembles... HELP!

well I actually have the same exact speakers as you, and and alpine 9831. The thing is, if your amping the speakers off the head unit itself, the actually rms is probably only 25 watts per speaker, so there just may not be enough power and maybe thats whats causing the static.. I am using an alpine amp, that puts 45 actually watts to the speaker and it sounds great.

Your system
Does your alpine have a bilt in cross over? If so set to about 120 on the hpf. This should allow you to turn it up a bit with out distortion. The best thing would be an amp. Do that when you can. As for the power of your deck real power on it is more 12 to 15 watt with peaks higher.

I don't think you can use the crossovers with the internal amp. Correct me if I'm wrong someone. But using the power from a headunit to power decent aftermarket speakers won't work too well. IMHO you aren't getting your money's worth out of those Infinity's since you're not using an amp. An amp should clear it up a lot. Of course your tweeter may be defective too.

my point was I don't think the internal X-over could be used with the internal amp, usually you need to use RCA outs to an amp to be able to use the internal X-over
Can you tell me if you can or not?

The internal xover seems to work fine in tuning my Infinity's, I just dont thing I am giving them enough power like everyone is saying... It just seems wierd that they would sound "blown" when they are not getting enough power and not the other way around...
The built in xover also works for my sub. I have that hooked up to an amp and I use the xover to adjust that too...so it seems to work with or without an amp.

hmm that's cool, never knew they worked like that
I would use just the X-over on the headunit and not the one on the amp for the sub unless the amp has a 24db x-over. Using both makes for a funny curve.
They may just be distorting at high volumes since you said it only sounds staticky when turned up.

So how can I fix the "distorting" at high volume?? Hook them up to an amp?? Like maybe a 50x2 and just leave the rears how they are??
Oh and my sub sounds fine, I am using the xover on the HU to control that.

First I'd bring it somewhere to see if they are blown or not before going out to get an amp. Either way though an amp is a very good idea. Yes, leave the rears how thy are and just use the fader to adjust the volume of the speakers to match each other.

if they sound okay at low/moderate volumes with no crackling... then amp them...
you shouldn't need anything more powerful then a 75 x 2 for the components alone...
you could also be experiencing speaker "fatigue" which is when the sound doesn't sound as good 60 minutes into the ride as opposed to 5 minutes... this is generally remedied by getting really expensive equipment... not much else you can do about it...
