After hearing all the suggestions of switching to 6.5's; I switched out my old pioneer 4x6's speakers and tweeters for some new JBL P650C 6.5 components. The components are running off my 2 channel Kicker 250.2 ; 125 watts RMS per channel, Max 250. My fronts don't seem to be pumping as loud as they should. e.g. my sub will over power my speakers at any volume. It kinda sounds like the sub and speakers are out of phase with each other, there is more bass then actual vocal volume. I set the gains to 3/4 of my max deck volume. I set the gains for the sub with a 60Hz tune and the fronts were tuned to music i listen too. Does anyone have any suggestions? I am not planning on amping the rears because i will not be driving the car from back there.
Chances are that with you 4x6 speakers you were putting too many watts into them and were clipping. Clipping can double the loudness and since 4x6's dont produce much bass, you would have made more mid and high sound. Problem is that it would be dirty sound
Yea i actually had to keep my gains lower for the old 4x6 speakers. I had to adjust the gain for the new components.. I noticed the midbass makes a big improvment when i turn the 125 hz filter off my pioneer deck and just use the kickers settings. With the setting turned off the cone makes a lot more movement, the cone was barely moving with the pioneer 's 125hz setting... I dont hear any distortion from the speakers with the setting turned off so im not to sure if it would be okay (i heard much about JBL's qaulity)??
Lower frequencies will always move the cone more, and yes, I'd recommend turning all of the deck's crossovers off. The amp should have a crossover and you should use that. (125 would be way too high anyway)
Any recommendations for a general amp setting for components? after i set the gain i backed the frequency until the speakers got a slight amount of bass from them and kept it at that point.
For 6.5" speakers use 60Hz, for 5.25" use 80Hz
If your amp is a dial type, you can download a 60Hz sound wave and play it with a mulimeter connected to the +/- terminals on the amp, adjust the crossover frequency until the voltage drops and stop when it does.
I'd recommend also setting the crossover for you sub to match the crossover for your fronts.
Example : Set your fronts to play everything ABOVE 60Hz and your sub to play everything BELOW 60Hz.
