Read This! Car Sound System

I'm trying to get a new sound system for my car..... I have a Grand Cherokee (I think its 98) that comes with Infinity speakers (4 speakesr-one on each door and two tweeters below the windshield). But I've already had to replace them twice because when I listen to all my EDM CD's, the high bass that this music usually has breaks the speakers even though I have the bass level really low...... so I wanted to get a good sound system (i dont really know about this stuff) so taht I can hear my trance/prog/house with good quality and a good bass (i DO NOT need that bass that you can hear a mile away that makes the car tremble )..... so what do you guys think? should I just buy a subwoofer or change the entire system? what are some good systems? good prices?

i have the same car and had the same problem

get some eclips speakers form car toys are some store like that they have great sound and you wont feel like you got bent over on the price or if you have the cash you cant go wrong with pioneer

Did you buy a separate subwoofer? or do you just use the ones built-in the speakers?

Is pioneer the best brand of speakers?

ya could probably just get away wiv turnin the volume down but if ya insist on changin things make sure ya get a new radio front so ya can keep the base down as any system ya buy ill be more powerful than the standard 1

RF subs arent usually well regarded in the car audio world. Their amps are awesome, but the subs tend to be a bit lacking

It's all about the amount of power you have to the speakers. If you get a decent deck and an amplifier for your speakers, with good speakers, you shouldn't have that problem. Most speakers blow, because there isn't enough RMS wattage running to them. A sub helps for bass, but isn't a necessity.

Edit - And, no, pioneer speakers are definitely not the best.

you best bet since you dont really know anything about car audio is to head over to a place like Tweeter and tell them what you want. Be sure to tell them the price range you are looking for, and keep it reasonable, but stay firm. They are salesmen just like any other business, and will try to get you to sway from your price range.

www.caraudioforum.com

they helped me find the best shit for my budget. i'd suggest asking anything and everything.

and by the way, most of them hate RF subs. but, just ask and they'll definitely help you out.

there are lots of car audio threads about, do a search

but if you keep on blowing your speakers then you're probably pushing them too hard! From you're thread, it seems that your speakers are powered by the HU. Considering that your speakers are Infinity , they will be of good power handling and sound quality.

AS someone mentioned, if you crank up the power, but you cant give it to the speakers, then you will burn out the voice coils as they cannot recreate the power that someone wants them to do, and they "tire out" quickly.

A quick fix would be to use seperate amplifiers to power the speakers. Adding a subwoofer would take strain off of the speakers, as it would allow them to play mid and higher levels of sound frequency.

check out www.thezeb.com awesome prices and really good service. I blew out my first infinity perfect 10 and they just replaced it for nothin.

What are you talking about.

Speakers blow when there is too much power appplied to them. A speaker has a maximum power ratting.

Watt is a measurment of power. power is a ratio of current and votlage. RMS - root mean squared is a method of averaging a waveform. W rms = Wp / sqrt2
A speaker will blow when there is too much wattage running to them.

A sub with a proper cross-over network will keep your high power bass out of the tweeter sections of the speakers protecting them from the high current bass section. Protecting your mids and tweets from blowing.

ALthough you are correct, it is actually EASIER to destroy a speaker by underpowering it. In a Car Modificatiobn magazine, they tested subwoofers to destruction, and many of them could take double the RMS power that the manufacturers said. Higher quality makes could even take TRIPLE the power for a good five minutes. (ALpine Type S RMS was 300W, but could handle 900W RMS!)

By giving a 300w RMS sub an amp that can only dish out 100W RMS, and you turn up the volume. The consequent power that the sub should produce would be consistent with its power rating. Say for example you turn the volume up to the 100%. The sub will try and also give 100% by trying to recreate the sound signal it has been given. However, since the amp only gives 100W, and the sub is trying to reproduce a volume equivalent to the power that 300W will give it, the sound will distort, indicating that the voice coils are being overworked and stressed. They will burn out...not in the sense that they've exploded (lol) but in the sense that they're "tired". imagine an athelete who cannot continue running in a marathon because they've got no energy. compare that to the voicecoil, except that it will not recover. If you run a system like this for a short time, you will find that, even at low volumes, the sound will still be distorted, as if it were at high levels, due to the voice coils being useless
