austinclay2 Posted June 29, 2016 Report Share Posted June 29, 2016 Alright so i have a 1000.1 memphis class d amplifier running 4 kicker comp 15's (250 RMS) ( I know beginner subs). I am also running a xs power d3400 battery with all 0 gauge. sorry about the useless info I'm just trying to be specific anyways the problem I'm having is the gain knob setting on the amp seems like it is making a connection then disconnecting. for example ill be driving and listening with the volume at the normal volume as usual and it is hitting hard and it cuts down to about 50% of the amount of bass then back to 100% and back down and so on. I thought that i had a lose connection back at the amp or something, so i checked and everything was tight and fully connected, so the next thing i done was mess with the gain knob and when i slightly press/turn the knob either way it makes a weird/crunching noise through the subs( no buzzing). If anyone can help it would be greatly appreciated. I was also wondering if i could install a bass/gain knob and maybe it would bypass the gain knob on the amp. I'm not exactly sure on how they work. thanks in advance! Link to comment Share on other sites More sharing options...
ShadeTreeMechanic Posted June 30, 2016 Report Share Posted June 30, 2016 I have an old Fosgate 1000bd that does the same thing like something in the amp is hurt. Maybe you could get an RCA cord that plugs into your phone to bypass your head unit. If it still does it then its inside the amp. Unless you have a woofer that is stuck or something wrong with a voice coil. I have a pair of C15s that I ran back in the day. Sealed in an 8 cubic foot box, man they sounded good. lol 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon) Link to comment Share on other sites More sharing options...
