first heres the system rundown-kdcx991 w/ipod in glove box(sub setting at 0, lpf @70hz), rf t400-4, aq2200d(no bass boost,subsonic @ 25ish hz, lpf wide open), rf t1652s comps, aq hdc3 15 d2(coils each read 2.1) @1ohm, 3.8cu/ft aero @34hz, xs d2400 under hood, deka g31 in trunk, all 0ga between batts and 2200, 4ga for t400-4.
so out of nowhere the lows sound substantially weaker and plain chitty,higher bass is substantially louder but again chitty. sounds like systems ive heard with gain set way high. peaky and uncontrolled, ive checked the sub(thought maybe lost spider/s) nothing i could see or feel, still stiff, played free air and nothing was obvious. changed rca's, grounded rca's, checked all power, ground, remote, speaker connections, checked box for any leaks, disconnected remote gain, played with all amp and head unit settings. Currently gain is set low at under 1/4, doesnt sound as bad at low volume but who likes low volume?. At this point im really thinking/hoping its a sub issue but dont know how to be sure. Any other ideas/things to check or try? thanks gents.
