Heres the deal. I have a 89 corolla sedan. It still have the oem tape deck. I'm planing to install a really basic sony cd player that i pretty much paid nothing for. i'm not really much of an audiophile. just want to be able to hear it.. lol. The front speakers current sounds blown. Buzzes really bad. Are there any cheap options for direct fit? Or can i get away with getting some stock ones from the junk yard? Rear speakers sound fine but will the new head unit be too powerful and blow up the rear speakers?. Thanks in advance for any advice.

My stock 10th generation Corolla speakers go pretty loud (i.e. at least 90 dB) without much distortion and no damage so far. If you turn them up to the point of audible distortion, or past the speaker's power handling capability, you can likely damage them with either the stock HU or aftermarket HU. The advice on the forum has been to go with the aftermarket HU, and the sound out of the stock speakers will be improved. To take out the stock door woofers on a 10th generation Corolla, you have to drill out four fairly large rivets. You should look and see if that is the way your Corolla is, or just take a rechargeable drill and a conical stepped drill when you go to the junk yard.
My 94 Corolla's original speakers were rated for 5 watts RMS and 15 watts peak. Stock speakers from your generation would be that at most, and likely a bit lower, whereas most aftermarket decks put out 18-20 watts RMS and 45-50 watts peak. I wouldn't bother getting any from a junkyard, because the stock speakers are garbage, and are made of paper which would be badly deteriorated by now. They wouldn't stand a chance.

Yeah, i'm just gonna buy some cheap aftermarket 4" speakers to replace my front ones. It says 15watt in the back of the speakers i'm assuming thats the max. Do you guys think the the stock rear speakers can handle the aftermarket head unit?
Also the head unit is 45wx4. Would these speakers sound okay.http://www.walmart.com/catalog/produ...ct_id=12518877 Is it bad if the speaker rating is alot higher than what the HU can put out?
Your rear speakers would be the same as the fronts. Also 15 watts peak. You would blow them very quickly.
Those speakers would certainly be better than stock. Although, to be fair, I could crap in a bucket and it would have better acoustics than almost any stock speakers of that era...
While you technically want speakers as closely matched to your power output as possible, those would work if that's what is in your budget. Just be careful not to turn it up too high, as you will clip the amp in the headunit, which causes distortion, damages the amp, and the speakers. It is much easier to kill a speaker by underpowering it than by overpowering it.
If you can afford a bit more ($37) I would look at these. http://www.crutchfield.com/p_113KFC1...2S.html?tp=105
Your car has a shallow mounting depth for the front speakers, so choices are limited, but I would take those over the wal*mart special anyday. Also, Crutchfield will throw in the speaker wiring adapters so you don't have to cut the factory wires.

Thanks for the advice . I'm a newb when it comes to audio stuff. What do you mean its much easier to kill a speaker by underpowering it? Are you saying puting aftermarket speakers with the stock headunit will kill the speakers really fast since the stock head unit is underpowered?
When you send power to a speaker, it flows through a coil on the back of the speaker cone that causes it to move away from the stationary magnet that is also at the back of the speaker. This movement is what creates the sound.
When you send a frequency to the speaker at a sound level that would require, say, 100 watts to do properly, but the amplifier cuts off at 50 watts, the outward movement of the speaker stops abruptly. This causes the speaker to draw much more than that 50 watts from the amp. The amp 'clips' and sends out a very distorted signal. This overloads the amp, and the distorted signal can technically overpower the speaker, thus blowing it.
yes, this is not a full technical explanation, but that is it in general. I hope I made it so that it is understandable for you.
Now, this is really only a problem if you turn up the volume to a point where you overload the amp, and you should be able to hear the sound distort before you reach this point. So long as you know the limits and don't push it the aftermarket speakers should be fine. You just don't want to have 300 watt speakers attached to a 45 watt amp if you can help it.
However, with the stock headunit putting out at most 15 watts peak, those 180 watt speakers probably wouldn't blow even if the amp was clipping horribly...the amp would fry itself before that happened. I would not recommend any aftermarket speakers with the stock headunit whatsoever. It'll sound horrible and won't last long.

I've dealt with cheaper Pioneer speakers previously and not been pleased with the sound quality of them. For the price being basically the same, I would go with the Kenwood's.
I had a set of cheap Pioneers and the highs were so shrill they made my ears ring, and the cones were very flimsy and did not reproduce mids well either.
