    there is 4 gauge wire running from the battiery through a fuse to the amp the ground is also 4 gauge that is only about 6 inchs long.

    no it runs along the side of the finder not touching anyother wires,goes through a drilled hole in the trunk of the car that is sealed with clear silocone,the dash flashes also but other then that no other lights flash radio doesnt flash or lose power, the ground is bolted to what use to be the spare tire area

    Hi again, None of the other lights dim or blink? Is the 4 gauge routed along or tie wrapped to any wiring harness? Is there anything attached to the same ground point? Sorry, long distance troubleshooting is tough so hang in there!

    Hi again, Do you have a multimeter or ammeter to help track this down? What is the cranking amp rating on your battery? Do you have other electronics, cell phone chargers that sort of thing hooked up?

Your battery and/or charging system isnt strong enough to handle the load the 15" subwoofer is causing.

you will need to add a capacitor to your audio system.

Can the car alarm cause the battery in my chrysler cirrus to lose charge

if the head lights continue to flash of course the battery will go flat. every time the head lights flash there is 65 watts of power coming out of the battery. Have the alarm modulator checked out as it should only flash once or twice to indicate that the alarm is activated.

How to adjust Dg11100 car amp

If your head unit has an amp gain, turn it up as high as it will go. If it is hooked up to subs, the head unit will say subwoofer output in the menu. Then take a small screwdriver and turn the amp gain on the side of your amp counterclockwise to zero. Turn your freq. up to about a third. Crank your system up, with a song with good bass, and slowly turn your gain up till the bass from the subs sound distorted, and back it back down. If the bass is drowning out the other speakers in your car, then turn the gain down some more. I find it works best if you have your trebble up high, your mid range at a little less than half. And your bass at zero or one. Your amp is cranking up the bass, so let your other speakers handle the rest. This allows it to sound clearly at higher volumes.

I've got a 1999 ford expedition with the Mach radio system in it and it does not have any bass playing thru the front or back speakers and i've changed out the factory amp thats in the back where the sub...

does the new amp you have have a hpf setting if so check to see if thats on, turn off the x-over so it will play both lpf and hpf, bass and treble. are all the speakers wired to the amp aswell, this is the only thing that would stop bass other than the head units settings.

Dash board, head unit/ subwoofers 2005 saab 93 has a "what fits" section, it will allow you to pick a new head unit that will fit the stock size of your SUV. As for as Amps, a Bass tube or Subs, they will help you too. They sell you have any thing you will need. Remember, this tip, grounding cables need to be drilled or bolted to a non-painted surface to the chassis.

Amp wire pushin to much base out of car speakers and not to subs

Umm.. subs are usually meant for bass. do you mean amp power wire? if you just want to be able to hear the mid's and highs better just turn the bass down either on the equalizer on your amp or on your cd player.

Bass making head unit skip

you need to get a headunit that has an anti-skip buffer, or get one with a USB input. With the USB input, you can put all your music on a flash drive and get rid of the CDs.

Headlights flash with bass

The sound system is exceeding the capacity of the Alternator, it takes allot of power to run the subwoofers, they make higher output alternators for just this situation, u will need one with at least 130 Amps output.
