[QUOTE="blazian87, post: 8399563, member: 574798"] You have a good start spending wise except for your wires and RCA. Could've gotten them much cheaper online from other brands like SHCA or KnuKonceptz. So.. you still have alternator whine? I thought it was resolved by replacing your RCA's? Are you sure your ground for your amps are solid? Make sure it's not loose and make sure you scrape off any paint or residue off the metal chassis. Pictures of it would help. It could be other factors but this is the first place I would check. Umm.. you're not supposed to max out your gains for active speakers. Only passive setups you give it all the juice you can give it and a lot of it is lost energy. Yes, you are definitely clipping. Clipping happens when you have your gain knob way too high. You are very likely to blow your speakers this way. This can also make your alternator whine way louder than it is. You have a very powerful 4 channel amp, you shouldn't even need to use that much power. Like I said, I think you're opening a new can of worms by going active. If I were you, I would probably put your passive crossover back on and try to make it sound the best you can before you blow something. If you really wanna learn, then you better do more reading on the net and/or ask more questions. Where is your listening volume at on your HU right now? If you're only using like half your max volume or less, then you definitely have your gains up way too high. Since you have a lot of power on tap for speakers, I would just set your tweeter and mids gain to the absolute minimum, and then slowly move your mids gain up until you feel it matches the tweeter. Make sure to put your volume up to about 3/4 of your max volume and set your crossover points first then play around with slopes afterwards. Focus on making your front stage sound the best you can before you even introduce the sub into the sound. You can either use a DMM to set a target RMS for your sub or a SMD DD-1.
