I have a Panasonic df903u model, a pair of 6.5 type r components and a pair of kicker k525 5.25's. The head unit pumps out about 22 watts rms to each speaker. However, whenever I try listening to my music "loud" it begins distorting. I'm not really listening to my music too loud, in fear of blowing my new speakers. But I was wondering, did I wire anythign wrong? Or is 22 watts just not enough to listen to louder music. If an amp is the answer at hand, are JBL's good with higher frequencies, I was looking at the 80.4 (i think, well the amp put out 50x4 into 4 ohms) I've basically been looking at sub amps so I really have no clue what amps are good for 6.5's and 5.25's. ------------- R.Troy

If you are hearing distortion at volume then it's most likely the amp in the head unit clipping or just plain distorting. I would add an external amp. JBL makes pretty good amps (they make excellent sub amps.) Although I am not familiar with the model you list, you probably can't go wrong with JBL.

double check all your speaker connections are in phase... also, low frequencies, even at moderate volume can cause distortion without sufficient power,, if connections are good, you may need an amplifier, and JBL is fine

Thanks for the info guys. But I was looking at the amps and I found a good deal on the p80.4 amp I was looking at. It says 50 watts x 4 into 4 ohms. I have no clue how to wire into 4 ohms with door speakers. Is there any diagrams that you guys could show me on wiring a 4 channel amp into 4 ohms?

If you just wire each speaker to a its own channel +to + and - to - (you have 4 speakers and 4 channels) each channel will have a 4 ohm load and you will get 50X4.

Oh I gotcha, It seemed like that was all I had to do, but since there was so little wiring I was worried I would have a very little resitence. But apparently not. Thanks guys!

Oh one more quick question: When wiring an amp to component speakers, do you just wiring directly to the crossovers, and keep the regular wires that run from the crossover to the driver and tweeter. Or must you replace the wires that run from the crossover to the driver and tweeters. ------------- R.Troy

I’m not exactly sure I understand your question. But the amps channel hooks up to the speaker input on the X-over. then there is a connection on the X over that goes to the driver and another that will go to the tweeter they should be labeled.

I'm talking about the connectiong from the xover to the driver and tweeter. Do the outputs of the x-over need to be changed, or are the smaler wires that came with the set fine. Can those smaller wires still handles 50watts rms? Or do they need to be replaced?

They should be able to handle the 50 watts but if you have extra cable it’s always a good idea to replace them.

Running an external amp is always preferable to running the internal one on the deck. The 903u is either 4 or 5v outputs so feeding an amp shouldn't be a problem. Even though Panasonic may rate the deck @ 22wRMS realistic without clipping it should be pulling 11-13 watts. Think of like this what amp fuse does the deck come with a 10A probably? and what is the fuse on the amp you want to run 2 20A fuses i.e. 40A, but all it's concerned with is ampfliying signal, not tuning or playing a cd just amplifying. At lower levels the difference between the internal amp and an external amp are minimal but as the volume goes up the difference become very apparent. If your wires are right, and you're distorting odds are it's the internal amp, not bad, just not best. ------------- Discount Car Stereo

On your new amp don’t forget to adjust the gains properly https://incolor.inebraska.com/weisinator/car-audio-basics/set_amp_gains.htm If they are not set correctly you will once again end up with a distorted signal.

Will it hurt the amp if I set the gains at max (that is if I don't have distortion at that level)
