[QUOTE="ThxOne, post: 8647348, member: 675210"] Was bored today so I went out to play with my stereo yet again... 1. Found out the front right midrange was not working, only the tweeter was working. 2. Found the reason my sub was only producing a narrow band of bass. 3. Using reference tones, reset the gains on both amps. Apparently the window made contact with my speaker wires in the door and disconnected the wires. I remember putting the window all the way down like 3 minutes after I originally installed the speakers. I never listened to them in the passenger seat after I put the window down. I just figured it was my poor hearing in my right ear and paid it no mind as I could hear the tweeter and assumed all was normal. Tis fixed now and the window does not interfere. Time alignment sure is different now lol. The subwoofer... holy crap. Ok, the box is tuned to 42hz... somehow the punch eq was cranked all the way up. That's plus 18db @45hz!!! So basically my bass was spiked high in the 40's. I set my volume on the HU to 33 out of 35 (From my research this particular model is good up to full volume). I set EVERYTHING to flat or zero or just plain no boost of any kind. I don't use bass boost or loudness on my HU ever anyway. Punch EQ is now all the way off. Since my box is tuned to 42hz and that is probably the loudest range it will play naturally, I used a 40hz (16bit 44100hz PCM WAV) and adjusted the gain to 40.1v. The sub is at 2ohms. Sub amp done. On to Barbara Ann. Same situation here but with a 1000hz (16bit 44100hz PCM WAV) and set the front gain (My Components - 4ohms) to 20.2v and the rear gain (My Coaxials - 4ohms) to 19.8v. She's done. Time alignment set to the drivers seat. The HU is taking care of all the distances on its own. I put my HU EQ setting back to the stored settings I had previously and it sounds so much better. It helps having that other door speaker working lol. The subwoofer level on the HU is set to 0db. The bass... holy cow, yeah, unboosting that 45hz allowed me to hear the bass above and below 45hz so much better. I was drowning it out for sure. I don't know how or why my Punch EQ was all the way up. Everything is 5 by 5 now. When I scrap the Jeep I will be transferring everything to the new vehicle where I will then do the proper install. By then I will have the matching US Acoustics "Mike" amp. I have so much crap waiting for the new vehicle, 200ft of (100ft each of red and black and blue and black Sky High OFC 14awg) speaker wire, 20ft (10ft each of red and black and blue and black Sky High OFC 8awg) speaker wire, 100ft of tesa tape, 4 -dual 1/0 ground blocks, nylon cable straps for speaker wires and power cables, grommets, connectors, acoustic speaker rings, sound deadening... anything I could think of I have been stockpiling.
