Line driver throwing amp into protect mode?

[kendall64 0]

i've had my system hooked up for several months now and just decided to add a rockford 360 line driver. i hooked it all up with the remote wire to the rockford 360 tied in with the remote wire to my amp. as soon as i started turning it up my amp went into protect mode. so i took i guess at that me adding the remote wire to my amp did it. so i moved the remote wire to one of my secondary batteries just to see and it still throws it into protect mode. the voltage doesnt drop it will just go itno protect mode. any ideas or suggestions?

just incase you need to know what i have system wise

2 18'' HDC3 audioque

DC power high output alt

3 batteries in the back (2 kintik HC1200) (1 xspower D3100)

big 3

3500 audioque amp

sounds like you're driving the signal too high.

so a line driver can throw an amp into protect mode? so all i have to do is turn down the line driver and it should fix my problem

I'm presuming you didn't readjust the gain after adding the line driver?

If not, turn down the gain. Sounds like you're sending the amp into hard clipping and triggering protection mode. Anytime you do anything that affects the signal level you need to readjust the gain.

What was the purpose of adding the line driver? What were you trying to gain? Chances are good the line driver was a completely unnecessary addition to the system that gained you nothing. There are precious few situations in which a line driver is beneficial, in any other situation they are nothing but a waste of money that unnecessarily complicates the system.

Sell it and recoup as much of your money back as you can.

I did a just the gain on my amp. I turned it down the reason i bought a line driver was because several people at the competitions i have been at have them and said you go boost your pre out signal and turn my amp gain down so my amp doesn't have to work as hard. Which the line driver did boost the signal enough to turn my amp down. I've just never heard of a line driver throwing an amp into protect mode. Thanks for everyone's input i have a justed the gain on the line driver and i have no problems no

alot of amps wont take higher then 6 volt input.

The line driver did NOT send your amp into protect, that is all thanks to the user at the volume knob.

The competitors you spoke to were either completely lost or pulling your leg, but considering they used the trite "work as hard" phrase it's easy to determine they have no idea. If you didn't have a thermal noise issue before the LD then you didn't need a hotter signal before the amp. ie, it was a waste of money.

Well hell i guess if that's the case then it was a waste of money

The internal "gain" the amplifier applies to the signal is a fixed figure; i.e. the amp works exactly the same amount. The only thing the gain knob on the amp does is allow you to obtain full power from the amp without clipping the signal with varying levels of input voltage.

I don't know who you talked to, but if you happen to run into them at competitions again...ignore any further advise they give you as they don't understand the basics.

Which the line driver did boost the signal enough to turn my amp down.

Sure, they "work" in that they do provide a higher voltage input to the amplifier. The problem is the only 2 times that's ever needed in a system is 1) if you have an unavoidable and audible amount of noise introduced into the system during the signal transfer, or 2) if the amplifier is too noisy with a higher gain setting (although this is a result of poor amplifier design and not a problem of low signal voltage). Unless you were trying to fix one of those two issues (which you weren't), then it's unnecessary and a waste of money.

The reason you purchased it is exactly the reason they continue to sell; misinformation.

I've just never heard of a line driver throwing an amp into protect mode.

It's not. Probably the overcurrent protection circuit is being triggered due to too much input signal for the gain setting, exactly the same thing can occur with any improperly set gain.

Honestly.....sell it or see if you can return it. You don't need it, it's not helping you.

The only time I have ever needed or advocated is when using multiple amps and a not that great head unit. When I was running my 4 Saz-1500's off of my single Pioneer (4v) head unit I added a line driver and it improved my score considerably. But outside of competition or multiple amps I would not suggest using one.. because you really don't have the need for it.

Sounds like a settings problem. Seriously it's rather simple. The input stage on amplifiers is meant to be adjusted. All amps make thermal noise when adjusted to "hot" to some extent. If this didn't exist and the gains weren't maxed then you didn't gain anything.
