[QUOTE="Jojo_Gutts, post: 8713463, member: 680456"] Ok so here are some updates. Between life and going down the rabbit hole with this one I just managed to install front speakers amp etc. I deadened the front doors. Closed the holes in door to approximate closed box. Fabricated brackets for my speakers, gave them ccf cone to door etc etc. Everything, though hectic went better than I hoped for. But I am facing a new set of challenges: 1. There is a hiss in my tweeters. Adjusting gain reduced it. Now not so noticeable at low volume but gets louder on higher volumes. Additional info is that on silent input (like silent aux input) with volume turned all the way up I hear a faint radio channel along with the hiss. Possible problems I feel are that I did not scrape paint for amp ground. But I am also getting my remote signal from "Antenna amp on" output from stereo harness. Will check ground tomorrow but do you think the second factor could make a difference too? I have a nissan versa note sv 2014 btw. It does not have a remote dedicated output for amp. 2. This is the real problem I am dreading. Only the left channels (front and rear) are working on my amp (sony xplod 440-ex). I know inputs have signal since I checked them with voltmeter and switched them (left to right) to double check. Speakers are working too. The test signal of the amp is also registering only on the left channels. Volt meter reads output form amps left channels (front and rear) but does not show anything on right. Its just the right outputs of my amp that dont seem to be working. Am I wiring it wrong? I gave it four speaker level inputs and am taking out four out puts with each speaker connected to its separate slot independently. I got the amp used off of ebay. Are the right channels circuits of my amp fried? Any way to check this? 3. In case the amp right channels are fried can this work: The amp has a mono way of connecting too. Using the left speaker positive and right speakers negative. It says on the mono labelling "L+R". So can I connect both my front speakers from these two terminals (using the one front mono out) for front and same with rear (from rear mono)? If my right circuits are fried will that mean I loose the right frequencies permanently or will the mono setup be able to combine them? Also will the amp be able to support 2 of my speakers from one output in what is essentially a parallel circuit arrangement in mono? I tried figuring out the circuit diagrams for amp. They are available freely online but I dont know how to read them (used to in high school but cant anymore). 4. In case my right circuit is fried and I loose my right frequencys permanently from amp. Will shifting the balance all the way left in the radio make up for the loss (in mono amp arrangement) since it is essentially mono now at the source? Would really really appreciate your help.
