amplifier's protect mode - Page 3

shesmackshard · 05-25-2009, 10:15 AM

I dont have a volt meter but my lights do not dim. And Im not replacing the amp, because theres nothing wrong with it. its a matter of troubleshooting the settings, and wiring. Ive disconnected all wiring except ground and power and protect mode did not come on. its not the amp. and considering its absolutely powerful when working, i have no reason to.

ill lower the gain down some more? Im getting the feeling its the gauge wiring.

I love you. And whoever else suggested this. It was gain. it works now :D

I turned down the gain but turned up the subwoofer levels on my HU and it works.

The bass is a liittttlle bit lower than before but its good to go, but will bigger gauge wire for the Power and Ground upgrade any bass levels? i thought I saw someone mention that and I was just curious because i never would have guess that.

i heard that every wire makes a difference, the power, ground, speaker wire, RCA's etc. they all make a difference. in a good way:P

GLade its fixed!!!
And yeah if the RCA'S are running on the same side of the auto as the power and turn on leads you will have cross talk also..........

Keep us informed!

shesmackshard · 05-25-2009, 09:03 PM

my rca's and power run the same side, and I dont hear anything...what should I be listening for? I'll invest in some buigger gauge wiring for the near future, and hopefully ill get even more out of the subs/amp.

Im gonna mess with the gain some more to see if i can find the loudest level its stable at with decent volume. Tomorrows my appointment with the shop, so ill see what they say

**jaggerwild** · 05-26-2009, 08:05 AM

Move the RCA'S to the other side of the car's door sill plates, you do want help right?

**lcurle** · 05-26-2009, 09:23 AM

you will hear engine noise if they are running down the same side, and your welcome ;)

shesmackshard · 05-26-2009, 10:57 AM

I dont hear anything haha, maybe the installer did some neat trick or something.

Well seems all good now, it definitely hasnt turned off at high volume so, it was a gain issue. **** summer heat :P

Thanks

shesmackshard · 05-28-2009, 03:42 PM

Bad news guys. Happened again, except now, it goes right into protect when I start the car. Ive disconnected all wires except power and ground, and it still does it. So its gotta be a faulty amp, no? I just emailed the owner of the place i bought it from, and hopefully ill get a replacement amp. What you guys think as far as troubleshooting this further? Im so sad right now :(

do you think this is a good amp for my subs?? sorry for my ignorance, again. my subs specs are on a previous page in this topic.

**carsey** · 05-28-2009, 06:03 PM

Probably almost certainly you killed the amp. happened to me twice because I overpowered them.

shesmackshard · 05-28-2009, 06:15 PM

how can you overpower an amp? playing too loud (wasnt too loud when it went into protect for the official last time). my gauge wiring isnt very big (8 gauge).

Crunch sucks so bad. Dont ever buy crunch.

**carsey** · 05-29-2009, 09:52 AM

You dont technically 'overpower' a amp its more like stressing the internal components by using too high gains/frequencies. Over time the components will become worn and eventually break.

So, can we clarify. You have 2 subs running at 500WRMS each? Correct?

Its wired up using figure 2 of this diagram:

Which is parallel wiring?

Do you know what ohms the subs are? My guess is they will be a 4ohm sub, but dont quote me on this....this figure is VITAL if running more than 1 sub.

shesmackshard · 05-29-2009, 07:40 PM

Im wired parallel yes, my subs are 4 ohms, SVC 500 rms 750 peak (read from box).

I had the amp 3 weeks.

shesmackshard · 05-30-2009, 03:11 PM

hmmmm I had a blown fuse on my power wire under the hood. Im gonna replace it and see what happens. If it works, what causes this and how can I make sure it doesnt again?

**carsey** · 05-30-2009, 03:44 PM

SPECIFICATIONS:

# 1 x 350 Watts @ 4 Ohms
# 1 x 750 Watts @ 2 Ohms
# 1 x 1000 Watts @ 1 Ohm

Looks like your amp is too small for the subs.

Id look for a amp with AT LEAST 1100WRMS @ 2Ohms.

Not sure why your fuse has popped under the bonnet, its usually because the cable for power has shorted out.

shesmackshard · 05-30-2009, 05:41 PM

how is that too small an amp? :p

my subs are 500 rms dude. Im overpowering them is anything.

also, i replaced all the fuses, and it still goes in protect mode after i turn the car on for about 5 seconds. and considering that fuse blew in the first place, should I just get a new wiring kit?

I'd be cool to get an answer on that buyt I think Im buying this soon

ordered this amp with new wiring...comments? I hope this all works out when i get it all pulled out and installed from scratch. and at least with crutchfield I'll have a warranty.

**carsey** · 05-30-2009, 07:52 PM

The amp you linked and gave specs before is too small as you have 1000WRMS from your subs wired as 2 ohms. The amp can only give 750WRMS at 2 ohms....250WRMS short.

The amp you ordered is 1000WRMS at 2 ohms. Which will do the job you want if you wire it in parallel.

What wiring kit did you go for?
