my head unit is the pioneer appradio 2. all of the bass and sub settings are at 0. never turned them up past that.
aren't 13w7's a 3ohm sub and don't jl amps do rated at all impedance loads? because that would make that problem not really applicable.check your head unit settings. make sure the sub settings are at 0 instead of like, -5 or something. Also check to make sure that your sub is wired in parallel instead of series.. your amps doesn't do much power at higher ohm loads so if your sub is wired in series, you could be cranking the gain up just to get 300 watts out of it.
so look up wiring charts and diagrams set up for a 3ohm load download a -4db test tone and read how to set gains with a digital multi meter follow those instructions it will still be loud but it won't fail like it's doing now.yes i know its a 3ohm sub

i think it has dual 1.5ohm voice coils
well as hard as your clipping it by fail I mean burning the voice coils of the sub and tripping the amp into protect mode every time you slow to idle, clipping is bad on the amp too and if you don't fix this you will have something fail!what do you mean by fail?
That's probably part of it but look under the amp section here there are sticky's about this stuff read them all! you have good equipment but if you don't set it up right you'll have some nice paper weight's instead!i thought the amp was cutting off because it dident get enough power to it.
The 13w7 is dual 1.5 ohm so it has to be wired in series because the amp is not .75 ohm stable.... but that doesnt matter cause the amp is a regulated power supply so itll put out 1000 watts at 1.5-4 ohms.check your head unit settings. make sure the sub settings are at 0 instead of like, -5 or something. Also check to make sure that your sub is wired in parallel instead of series.. your amps doesn't do much power at higher ohm loads so if your sub is wired in series, you could be cranking the gain up just to get 300 watts out of it.
upgrade an alt for 1k watts? not sure i agree with thatYou will want to upgrade alternator and/or add additional battery. May be worth having your alternator and battery tested to make sure neither is weak. A solid stock electrical system should power that amp well enough, but if something is weak it won't hang.
