[QUOTE="thejoker989, post: 2449397, member: 567586"] I currently have a 2-way setup in fiberglass kickpanels and my subwoofer in the trunk. The imaging is right on, but the midbass is severely lacking. I want to add some woofers in the factory door speaker location and make it a 3-way setup, but I dont have the money to change my amps and add a seperate crossover to go all active. So what I want to do instead is... Use the h/u low pass filter for my subwoofer at 80 hz. Have the frontchannel h/u highpass filter set for 80 or 125 and first going to my amp that will be used for tweeters and midrange, but I will set the highpass on that amp to somewhere around 300, making my h/u filtering do nothing for those speakers. From there run a short patch cable from that amps output rca's to the woofer amp. The woofer amp would have a low pass filter set around 250 - 300 and the highpass will be 80 or 125 depending on the h/u. How do you think this sounds? Save the money and go fully active? Will the tweeter/midrange amp filtering have any effect on the outpout rca's? What is a decent (~40$ max each) woofer? Does my theoretical setup work? Is there anyother/better way of doing it? My woofer amp has a bandpass filter, would you ditch the preset h/u crossover points and tune it all with the passive amplifier filters? No rear speakers will be used. What I currently have: 15" Rl-P D2: Orion D1200 (600 watts) 3.2ft^3, 28hz Diamond D661a: Cadence Q2150 (125 watts) knu 4-gauge. [/QUOTE]
