What makes speakers scratchy when music's loud???

Well welcome back Paul, we all missed yah... or at least I know I did

Nice to hear from you man!

I am certifiable already .......... but that has nothing to do with car stereo.

for those who DON'T know me, I try to explain things using principles of math, physics, engineering, etc .. rather than relying on a lot of misinformation out there. I am not in the car stereo business, so I have no products or brands I am pushing although I do have my personal preferences based on experience or independent testing. If I ruffle your feathers, PLEASE don't take it personally - I am most likely just trying to get you to see something in another way.

I have the same problem as the guy who started this thread. Its simple, an amp will solve the problem. But amps are $$. lots of it. If you can afford it, get it. If you are like me and do not really like blasting loud noise, just don't turn it up so loud. Roll up the windows, close the doors, shut the moonroof, it will sound louder and cleaner. I have the Sony Xplod speakers too, the 6.5" ones. They are good speakers. But your internal amp on the HU just isn't powerful enough to drive the speakers to there full potential. Amps of a good kind cost around $200. I don't have any reccommendations, but you might want to try something that matches your current speakers and/or HU.

"certifiable already" means what?

You should know! You know... certifiable... to be in a [psychiatric] institution...
You are, too! :finger:














Then again... I am too... :smoker2:

Car audio is my specialty, and MOSFET is not a cooling chip. MOSFET, or Metal Oxide Semiconductor Field Effect Transistors, are a more efficient form of transistor that have less resisitance. Thereby less heat, and cleaner, louder sound are produced over amps and HUs without MOSFETs.


As for your amp problem, a crossover is not your solution. CXHatchback hit it perfectly with the wattage speech. Your HU simply cannot push your 6 1/2 and 5 1/2 speakers efficiently. A crossover will rob even more of that dwindling power supply. So my advice is also to get a decent 4 channel and call it good, because you damage your speakers much more by UNDERpowering them as opposed to OVERpowering them. If absolutley necessary, a crossover can be used, but you dont even have subs or tweeters, so the options on your HU and that amp you get should filter frequencies sufficiently. Bottom line: you've already invested in a deck and speakers, so why damage them both by not powering your speakers efficiently? Get a DECENT amp, your system is only as strong as the weakest link in it.

Not true,
MOSFET is a type of transistor that is more efficient and cooler running for high power applications.

Also,

yeah, don't turn your speakers up so you hear noises that aren't supposed to be there. That's really bad for the speakers. If you want to listen to it that loud, buy an amp. It's far better to over power a speaker than underpower it. You can actually listen to music louder on factory speakers with an aftermarket amp than aftermarket speakers on a factory head unit / amp (as long as you have the crossover set high enough). All the noise you're hearing is just distortion in the amp of the head unit. That will eventually destroy your speaker.

although now i realized that j-spec already said all that and i wish i read the second page before posting... whatever... right on j-spec

I've found that alot of this cracking and scratching type noise can be poor connections . Starting at the head unit and ending at the speaker , there are connectors that can deteriorate through oxidization and/or arcing . The aftermarket hardware has nice RCA type connectors . They can benefit from being reseated now and then . Remember , the speakers will reproduce whatever audio signal reaches them .

Are you serious??? Can we just ban these kind of people?

im gunna use this to ask u a ? hai. Would you recommend a 16Ov.2? or something else for the money. the 15in. is looking pretty nice
