sub "popping"

roystitantn · 12-13-2006, 10:10 AM

real quick question for you audio guys. i installed a LOC and a MTX amp in my '06 KC. when i turn the truck on the sub "thumps" before the music starts playing. i think it is a bad amp, but i was wondering if you guys had experience with this. thanks in advance.

Check the wires where you hooked the LOC to...sounds like you got something other than audio wires. You could have gotten a window or power lock wire.

where did you get your turn on power from . if the subs paly and just have a thump. this is turn on pop . your amp is turning on before you have audio signall. turn your radio off with car running and see what happens. you may have hummm. you need a loc with remote out if this is the problem

Turn on pop for sure....some amps have delays you can adjust. Tech is right something is kicking the amp on to soon....

sweeeeeet....i get to tear my interior out again to try and find another remote. would it be best to get it from the remote coming from the radio? i would think this would be the best place to grab it. i was just lazy the first time i installed my amp. i guess i won't do that anymore. thanks for the help fellas. i was worried i'd have to replace the amp, which i didn't want to do cause i really like it.

yes always get the remote wire from the head unit if it is available.If not use an loc with remote out if possible.

Definately try connecting to your head units remote turn on wire as instructed by tech12volt. If that doesn't work you may want to try a relay on the remote wire. I don't know what other accessories you have in your truck but it's worth a shot. Use a Single Pole Double Throw Relay and connect as follows.

Terminal #86 - Remote turn on wire on head unit

Terminal #85 - Chasis ground

Terminal #87 - 12 Volt + constant

Terminal #30 - To amplifier

Terminal #87a - Unused

Could also be an issue caused by the factory amp. What radio do you have in your titan?

Good to know

Can you pull power from the factory R/F premium radio? I've heard you must do a LOC from a speaker to power additions to this system. Can you get power from the existing sub feed so it's already filtered?

i have the midline radio. the 6-disc mp3 changer. i haven't had a chance to tear it apart yet. i will do it over the christmas break. thanks for all the advice fellas.
