dparm Posted June 20, 2009 Share Posted June 20, 2009 Recently drove an LGT but was a bit disappointed with the stereo. Is anyone running aftermarket speakers (components) on the stock headunit? I will be yanking my Polk db6501 components from my current car if I end up with an LGT and would be curious if it's even worth it. Link to comment Share on other sites More sharing options...
suzysube Posted June 20, 2009 Share Posted June 20, 2009 It is best to run some power to them(amp). I had some type s coaxial for a while hooked up to the stock head unit,...........and was not as good as the stock speakers. Since then, i did rf 360.1, type r components, and an amp, and love it. If i were you, i would keep the stock speakers until you want to do a full set up. Link to comment Share on other sites More sharing options...
Chad W Posted June 20, 2009 Share Posted June 20, 2009 You can expect an increase in sound quality, but a decrease in overall volume, as your polks are probably less efficient. Link to comment Share on other sites More sharing options...

Yes, thats what i meant to say. Stocks are not better, but give you more volume. Link to comment Share on other sites More sharing options...
dparm Posted June 20, 2009 Author Share Posted June 20, 2009 I take it they're super-low impedance, like 1 ohm or something? Link to comment Share on other sites More sharing options...
Chad W Posted June 21, 2009 Share Posted June 21, 2009 No, they just have a higher efficiency rating, 1 ohm would probably fry any stock radio/amp. It would also draw more power. Higher efficiency means more volume with the same power. Link to comment Share on other sites More sharing options...
dparm Posted June 21, 2009 Author Share Posted June 21, 2009 Umm, doesn't that imply that they're low-impedance? Meaning that it takes less power to move them? Most factory stereos run low-impedance speakers. Hondas are typically 1 or 2 ohm. Link to comment Share on other sites More sharing options...
Chad W Posted June 22, 2009 Share Posted June 22, 2009 Impedance and efficiency (which is called Sensitivity and commonly measured in decibels produced with one watt of power, one meter from the driver) are completely different things. Many manufacturers make the same model and size subwoofer available in different impedances. Often there is little or no change in sensitivity among them. That's not say lower impedance can not be part of recipe for higher sensitivity, but there's no hard and fast rule as speaker specs are all dependant and interrelated. One thing that is certain about a lower impedence speaker is that will draw more power for an amp, provided that the amp can handle it. Low impedance speakers are not completely uncommon on factory systems, especially premiums ones like Bose. The majority of basic systems do utilize 4 ohm speakers and would have issues with lower impedance. Power handling and sensitivity often are interrelated in that speakers designed for high power handling often sacrifice sensitivity by using stronger and more durable materials. Conversely highly efficient factory speakers are made from lighter weight less durable materials. An aftermarket speaker may be -3db at 10 watts when compared to the stock speakers, but at 50 watts the aftermarket speakers would be more than 4 times louder and the stockers would be destroyed. When you are talking about components, the crossover networks also eat some power, the more complex and sophisticated the crossover is, the more power it takes.

dwolson2 Posted June 26, 2009 Share Posted June 26, 2009 Replace the factory radio, I replaced mine and have no need to replace the speakers, plus now i can listen to my ipod. search the JDM conversion in Interior audio. it will be on the 1st page Link to comment Share on other sites More sharing options...
