Sub/Amp Cuts out randomly at high volume deep bass when car idles. Brand new system, lights and dash dim.?

Question

S12L7 Kicker 750w rms with mono 750w kicker amp (underrated actual is 932w rms) also running a 1260w ATX amp for the 4 infinity speakers. Lights and dashboard dim, and when i idle and crank it, when it hit hella deep loud bass from time to time the sub/amp cut out for a few seconds and all u can hear are the 4 infinity speakers. Is this a power problem? When the amp doesn't get the juice it wants does it have a safety temporary shutoff? When im driving giving and gas it never cuts out.

Answer 1

Sounds to me like the Amp is going into protection mode. is there a light that you can see when this happens? Most amps go into protection mode when they are clipping. Clipping is excessive distortion. The distortion is tough to hear with bass, but it's def there.

I reccomend changing you setting as follows.

Insert a CD or play Ipod song with your Deck volume at 80% of its max. Then, Adjust the bass level control from min to max. Same with your Highs amp. When the sound doesn't increase at all, go back slightly to get the tipping point. You want it at the tipping point of no increase. The Bass level is not a volume knob. It is a level input adjust(.1v-4v) and it needs to be as stated or you can have some noise and cut out issue's.

As for playing, you dont want to go past 80% volume now. reason is because MOST Headunits start creating ALOT of distortion after 80%.

If you follow my advice, you will have the cleanest power going to your speakers and the overall sound will greatly improve. You can play it at much louder volumes for longer periods of time without any issue's. Most blown subs are from distortion from a bad set-up.

yes its a power problem and its a very easy fix just buy a or a couple capacitors (more and bigger is always better) inphase audio installer should have caught that and should have said something to you so in my opinion they screwed you so if i were you i would double check there work. the reason why it's doing that is the amp is pulling a lot of power away from your alternator which makes your lights dim and if your amp doesn't get the power it needs it will go into protect. So a capacitor and it wouldn't hurt to buy a bigger alternator, you can look into a batt-cap, it's a battery and a capacitor in one.

what gauge wire are you running to your amp, also how far is the ground to your amps, it needs to be very close like maybe a foot or not to much more to your amps and grounded to a sanded area down to the metal to get a good ground.
