When I turn up my hu to like 40 with 0 bass the amp go into protection mode? this did it with my last amp as well? is there a max on how loud i can go? or will i have to go aftermarket to get the max i want it to?

 

what kinda amp is it? mine hits 40 just fine without the amp shutting down or going into protection mode.

 

1000 watt kicker powering 4 jl 8" i mean there is plenty of power it just that it shuts off

 

Have you set your gains properly? How hot is the amp getting? I wonder if that shutdown is thermal protection and not clipping. Also, give me an idea of your power leads... what gauge are you using and how long is your ground?

 

im useing a 8gague kit and my ground is about 2 feet, there is no control lvl on the amp, the amp is in a well aired area and isnt getting hot at all any ideas?

 

Probably amp clipping protection circuit, imo.

Stock Pio HU? I scoped my '06 Pio ipod HU and it clips around 53 so I use 50 as my max @ HU. Check gains. Also, how much voltage is your LOC putting out?

Of course, as Spr0ket asked what size are your wires? Is your ground good? With 4-8's, is speaker load correct for amp? And check for full 12v/plus @ the amp.

 

Holy crap man!!!!!! A 1000 watt amp needs larger cable. You can't get enough current through 8 guage to support that amp. I'm not saying that's definitely your problem but it sure isn't helping. For 1000 watts most information I've seen recommends at least 2 guage.

 

Chadfo has nailed it dead on. Dude... you are cooking those arteries like you would not believe. Just touch the wires on a mild day to see how hot they get. Choke choke choke. The the very minimum, 4AWG for the xA since it's not a very long hop. For anything over 15' @ 600W you should run 2AWG or larger. You can get away with 4AWG but you would need to upgrade to 2AWG later so why not fix the problem now. For the cheapest wire you can find look around for some high strand count welding supply cable. It's cheap and will fit your needs at a low cost.

I think the problem is solved once this is corrected. Oh yeah, your ground wire doesn't need to be long (24" is prime length) but it needs to be the same gauge or larger than your power for effeciency purposes. Once you have upgraded those wires to something of decent size, you will not only stop the cutting out but you will be able to draw upon the current your amp will really pound with. Just make sure you do the Big-3 to help the current flow. If you don't know the Big-3, do a search as I have posted some fairly informative articles on it.

All Kicker amps have a gain setting. You may not be able to control the volume level, but you can set the gain. What exact model is the Kicker amp... I'll grab my books from the shop and give you some information on the settings you need. As far as how to set the gain properly, you will need to get a digital multi-meter and a disc with +0 attunated notes.

 

I just noticed something. You're in Lee's Summit, MO. When I have some free time, I'll be happy to help you fix the problem. Between both jobs, school, and family though, it's going to be hard to find the time.

BTW - I've seen your setup and it sounds very nice. Just need to fix the small bits.

 

but i was haveing the same problem with my 250 jl with a 8g kit?

 

as well i hooked up my subs to a friends car with an aftermarket hu and it sounds alot better and doesnt cut out when turning it up... dont you think it could be the hu?

 

I'm almost thinking it's in the LOC.... maybe Kicker/JL have a protection circutry against hard clipping.... make sure the output gain voltage on the LOC matches the input gain voltage on the amp....

But you definitely need to upgrade to 2ga. or 0... that will help your amp breathe even if it's not the cause of the shutting down...

 

I agree. If it's working fine in your friends and not in yours, you are probably overpowering the input circuit in the amp. Are you using a line level converter on the input to the amp or is the amp capable of handling power input?

 

what i did was i left everything hooked into my car and just ran rca cables from his car into my amp... so the amp and everything was still in my car im still thinking its the hu 100%

 

I mean how is connected in your car. How is the signal getting from the HU to the amp? What types of input does the amp have? What's the model # for the amp?

 

sounds like the lack of the line level converter. He's putting full HU wattage into the amp on the low side.

 

Yeah, that's EXACTLY what it sounds like. Shouldn't be a problem though(as long as his amp can take a higher input voltage) if he would turn down his gains. He'd get a better match to his deck that way and still get full ouptput power.

You prolly won't need a LOC unless it's a REALLY old amp. Even most old amps can take up to a 2v input, my Memphis is a few years old and it can take up to 5V input.

Find someone that has a level setting disc and let them do it properly for you. Chances are if they have a level setting disc, more than likely they already have a better understanding of gain structure than most people do.

If you don't want to find someone to do this for you. Your best bet with the least frustration(and least performance) is a LOC. Buy one and install it near the amplifier. That's the BEST place to mount them for best LOC performance. As an added benefit, you get to run shorter RCA's and save alittle money.

 

thank you so much
