[QUOTE="Gauntlet, post: 88081, member: 545529"] I have a 92 Cutlass Ciera SL, which has stock 3.5" speakers in the dash and 6x9" speakers in the rear deck. I have replaced the 3.5's and 6x9's with Infinity Kappa speakers, 35 RMS at 4 ohms for the dash, 110RMS at 4ohms for the rear. My Pioneer 8400MP HU is currently powering them. I would like to add a pair of Audiobahn ACX412 4x10" speakers (110RMS at 4ohms) in the door panels (basically the only speaker that will fit), and a pair of Infinity reference 105t tweeters (50RMS at 4ohms) near the window molding. I want to power the 6x9's and 4x10's with a Power Acoustick Sapphire SP4X800 (pushes 85x4 at 4 ohms) and power the 3.5's and tweeters with my HU. My questions: 1) How do I install the 4x10s in my door, since I will have to cut the metal of the door panel and make a custom install? I can handle the tweeter installtion, I have done those before. 2) I know how to wire the 4x10s and 6x9s, wire the speaker leads to the amplifier leads in parallel, and wire the amp up. The only question I have is, since my HU has 3 sets of preouts (front, rear, and sub) does it matter which set of preouts (front or rear) i hook the RCA cables up to, or does it make no difference? 3) Lastly, to hook my tweeters and dash up to the HU. Well, the dash are already hooked up, so nevermind about that, but for the tweeters - do I just splice the wires into the now bypassed 6x9 wires? Thanks for all the help, it's much appreciated - you guys are teaching me a lot! [/QUOTE]
