[QUOTE="qkassidyw, post: 4894264, member: 598965"] I am not completely familiar with this amp but in my experience it is always better to leave all crossovers OFF on the Head unit. As long as the crossovers are variable on the Kicker amp then you should be able to everything you need on the amp. The crossovers built into the deck will not be as good as the ones on the amp (even though Kicker is not known for their crossovers). Using BOTH will cause weird rolloffs and you could loose some needed frequencies. I had a question about your mids....do they have built in crossovers on the speakers? You do not want to go much lower than 80Hz on the mids and you want to get make sure they don't go higher than what the tweeters will play but you don't want them to distort from frequencies they don't like. Mids generally need a bandpass filter and I am wondering how you are leaving out the lows and the highs by just using the amp. Playing highs through them will sound like poop. For the tweets I am assuming they have built in crossovers and I would turn the crossover on HI-Pass for them and start low and adjust upwards until they sound right to you. For tuning I believe there is a thread on here but here are some pointers: 1. Turn off all EQ settings on the deck (Flat for pioneer, no crossovers on) 2. Turn the volume on the deck up to 3/4 (I think 37 on the Pioneer) 3. Get a good quality CD or song off your iPod and play 4. Adjust gain slowly until you start hearing distortion (you should be able to tell with it at 3/4 volume) 5. Once distortion is reached, turn down slightly until it goes away. As for your RCA connections make sure the tweeters are on the same channel (Front) and your mids are one the same channel (Rears). Another way to tune is to use a DMM and using the same steps listed above (except you should be playing a 200 hz tone for mids and a 5 KHz tone for tweets) but actually disconnect the tweets and mids from the amp and measure the voltage on the output. Example: Your mids are 4 Ohms, and require 100 RMS so to get what the voltage output should be: V=sqrt(PR) V=sqrt(100*4) = 20V (AC RMS) So set your DMM to Volts AC and adjust the gain until you see 20 Volts on the display when running a constant tone and that will be the optimum setting. The best way is to use an O-Scope but I am assuming you don't have one. [/QUOTE]
