Amp going into protection

[audioarsonal 10+ year member]

Would it because of all the power i'm losing? When i'm pounding i'm around 11.2 volts.

Try removing the cap once.

I don't think so. The LED on the capacitor said 11.2 when I was pounding.. then I decided to take off the CAP to see if it'll help..

Just checkin you might be pullin to much power and maybe the cap was draining off the extra you needed.Try re grounding it.Or just add another battery.

i'll go check where these guys mounted the ground and i'll try to find a different spot to ground it.

It should be to bare metal.

seems like its not so stable at 1

I agree. Its says it is, but probally sucks a**. It gets hot super quick, just wire it down to 2 ohm, and call it a day.

edit: Just read to rest of the post.....I would really get another battery, since your voltage drops below 12. You could try the ground put I doubt that your problem. But then again every situation is different

Can't wire it to 2 ohms, its 2 dual 4 ohm subs..

Also I checked the ground, its on metal but theres paint on it, i'm going to take it to my dads shop tomorrow remove the ground, sand it down to bare metal then see how it takes it.

When bumpin do your subs get stinky if so your low voltage is clipping out your amp, and getting dirty power to your subs. Low voltage causes your amps to go into protected sooner also.

When your voltage drops your subs will still demand the power and your amps will try to compensate for the low voltage. When this happens your amps power just turns to heat and sends heat to your subs. This causes your subs coils to heat up and stink. Keeping higher voltage helps your amps to maintain a more stable cleaner power and efficiency to your subs.

I saw some one say lose the cap. (I AGREE) Caps can take more voltage away from your system when they are filling and do not last for more then a few minutes with over 1000 watts. A battery would make a huge advantage over a cap. Caps are for short bursts of power not for a 2000 watt audio set up.

do you guys know where I can get some good 1/0 gauge wire from for cheap? and how much would I need, 25 ft?

 

[mlstrass 5,000+ posts]

For the BIG3? Just get some 2/0 welding wire locally or see if any shops have 1/0 audio wire. Should only need around 12' to do that on your vehicle, plus a 250a fuse.

Does your truck crank over kinda slow? I'm still wondering if the batt cables are corroded and on the way out as you said the alt tested fine.

 

[jbizzle 5,000+ posts]

What do you mean crank over? Like turnon? if so, it always starts fine, I had my dad check my belt to see if its loose/worn and it was fine.. I added a 4 gauge ground to the bat, and cleaned the ground where the amp was, helped a tiny bit. waiting to get some wire, some wholesale place is selling it 50ft for $90, but I don't need 50 feet :/

Subs don't demand anything, they take what they are given. The incoming signal and the gain setting on the amp will determine how much power the subs get.

Your amp is probably going to thermal protection due to low voltage. If your running all of that on a stock setup you should definitely consider the Big 3 as an option and maybe a new battery/2nd battery.

1500 watts is gonna be a drain on any stock system, even with proper gain setting.

Lets assume 80 percent efficiency, at 12 volts... That's still a 156 amp draw. More than most stock systems and batteries can supply. However, I don't know what your stock electrical is, so the best way to see how much is enough is to do it methodically.

1. Do Big 3 first

2. if that wasn't enough then do the battery

3. If thats not enough upgrade stock alternator (you'll be more than fine stopping at step 2 with that kind of amp)

Alright alpine, i'm trying to do the big3, only thing is just looking for some 0 gauge for cheap (just blew all my money on the new setup)
