Awhile back I posted about my 2 sub's wiring to my amp (two 4ohm subs wired into the bridged rear channel on my Rockford 800a4, making it a 2ohm bridged mono load) and we came to the conclusion to wire one sub off the front channel bridged, and the other sub off the rear channel bridged. Well I spent this afternoon redoing all that, tuning each sub so they were the same gain, bass boost, and hz wise. Well, she sounds like shit!! I had to turn the gain down, or the subs disort, but then they put out no volume like before, and when I crank the HU up they sound like I have the subs mounted in a 5 gallon pail... (believe me...I built a sub from a 5gal pail once it was an expirment when I was 15 ) So I kept tuning it trying to get the right balance between gain, frequency and bass boost, and no luck. It almost sounds like the ground wasn't fully grounded, but I checked it and the grounds are fine. (note - it sounded just fine before I rewired it) Or like it isn't getting enough clean power or something, I don't know. I bought 2 gold plated RCA splitters to split the sub amp RCA cable between the front and rear channel on my amp, there wasn't any other way to do it. Could that maybe be part of the problem? If I can't find a solution for this, I might as well wire them back into a 2ohm load off the rear channel and call it good. Cliffs: Rewired my two 4ohm subs from a bridged 2ohm mono load on the rear channel (Rockford Punch 800a4) to the left sub off the front channel, and the right sub off the rear channel and it sounds like shit now. Both front and rear channel settings match. ie. Gain, frequency, and bass boost. (yes, both channels are set at low pass) Any suggestions?
