Speaker + resistor = joy? - help a mom replace a $299 6.5" OEM auto speaker
I come to my dear instructables seeking some basic understanding. Let me just preface this by the fact that I have no problem getting dirty or cracking things open to try to understand them better- probably better at taking them apart than putting them back together - but I try...(hubby kids that I always end up with spare parts too).
this leads me to my current problem. The right front speaker in my 2001 sienna minvan decided to blow after much to much green day playing. Yesterday I just couldn't take the awful hissing anymore and popped off the panel to pull out the speaker. I'm kinda used to my old cars where I could pop down to best buy and pickup a new set. Not so with Toyota -
OH NO they have special 2.2 Ohm speakers that are proprietary to Toyota. So I went to the dealsership and was told that a new right front JBL speaker replacement (model 6689) was going to cost me $299. - you read that right $299 for ONE 6.5" door speaker.
I found a website briefly outlining how to take a plain 4 ohm speaker, get a 1.8 Ohm resistor and be done with it. - http://oneilengineering.9f.com/photo5.html - So there are a few questions that I need answered by someone with experience.
1) Is it that simple? - I may opt for decent replacements and I'll do both door ones so they match ...
2) I can't see from that fellows photos exactly how the resistor is attached - is it just soldered in place bridging the two end where the + /- leads are attached? any existing ibles with closeups? I couldn't find any. is a resistor directional?
3) I read somewhere that if I'm adding the resistor - that heat will be generated from reducing the current - Is that true? if so - do I have to shield it somehow?
Thank you for any help !!!
