Looking for ideas for my next build. I currently have an 80PRS, a DC 175.4, and CDT HD-62CF comps for front and Polk dB651's for rear. I have three choices for running active with rear speakers (which I want, unless it proves more of a headache than they are worth):
1. Run crossovers at HU to the DC 175.4, with each channel of the DC in full range. Rear speakers will have to be ran off the HU's amp (ok, I have only heard you can do this, don't know if it actually can be done, or how to do it). This option costs nothing.
2. Trade the DC in for a Zed Leviathan. HU will be ran full range, all crossovers will be on amp. RCA's for mids will each have a Y-adapter, so they will go to channels 3-6 on the Levi. Channels 1-2 will be HPF for front tweets, channels 3-4 will be bandpass for front mids, channels 5-6 will be HPF for the rears. This will cost an extra $400.
3. Screw the rears, just run crossovers on HU to the DC. This also costs nothing.
Opinions? I'd like to not spend the extra right now, but give me pros, cons, and your opinion regardless.
