Have you tried using the Remote Knob, and not using it.

If I unplug the remote knob, the sub gets even quieter. I can't see the cone moving, I have to put my ear up to it to hear it barely make sound.

dude is that gain on the lanzar almost all the way off?

It's at ~1/3, which is where the DMM said 52.9volts ( sqrt(4*700)) I had the bass knob plugged in and at full. If I unplug the bass knob, it virtually turns itself off.

how exactly are u setting your gains? because.....each amp prolly doesnt have the same deal with it. ou may be at like 60hz on the amp knob, and different on the other, changing the whole deal. and what are you playing to set your gains?

sometimes setting ur gain to ear is better,i know on my orion 2500d a dmm reading and by ear totally not the same,i mean by ear it really bumps better.

what tone did you set the gains at??

I dont care what anyone on here says you have the gains set wrong..........

Reset the gains.

Ive never ever ran a amp with the gains at 1/3.Notice the other amp is at full gain and this one is at 1/3????Hmmmmmmmmmmmmm.

Reset the gains.//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Problem solved.

How would I go about doing that? I had the DMM reading 52.9

I was using a 0db test tone, i believe 45hz; It was like 2 minutes long, so it was constant.

 

[vetkilr 10+ year member]

Should be done at 60 hz I believe.

But there must be a boost gain involved or something......

Do tones at more then one tone and check volts.......20/30/40/50/60.........

I never do tones or dmm I go by ear.

Whats the volts coming out of the other amp by the way?

I set the gains with the bass knob at full, and adjusted the gain on the amp. The DMM said it was at 52.9v I don't see how it overrides it if I can still adjust the gain on the amp for the correct voltage reading on the terminals
That's what I don't understand. 700w @ 4 ohms the output voltage in AC should read 52.9v. That's what I set it to, yet It wont move the sub at all.

On my RF amp (200 watt), I can bounce quarters off my roof @ 20hz

I used an oscope, trust me. the knob overrides the amps gains.
You should try setting your gains with reduced tones i.e. -10dB tones. Not 0dB since music isn't constant.

also what does your elec. system consist of? remember you'll need power to make power.

exactly

dont know bout -10 but I hate the whole dmm settin thing...never used it.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Ohms law..........dont think its needed yet as hes only gettin 200-300 watts.

umm............ 52.3v shouldn't it be 28.x volts? ( sqrt(4*200)) ??

My stock alternator is a 117amp.

Edit: I'm going to go out and hook up the lanzar again. Set the gain by ear, and try without the remote knob. will let you know in a few.

In what order are you supposed to hook up the B+ and ground? I have always hooked up the B+ first, then the ground. My system was all off, car shut off. I put the B+ on, then when I went to hook up the ground wire, it sparked.

WTF? sounds to me like an internal short...
