Hey Guys, I'm trying to figure out why I am not getting any bass when the volume is not turned up. When the volume is turned up there is plenty of hard hitting bass. I have an lc2i to a kicker cx600.1 and a 12" L7. Could this is a tuning issue? Any input would be helpful. Thanks!

 

Forgot to mention that i have the Bose system.

 

I am by no means an audio expert, but most people have ditched using any type of Hi-Lo converter and tapped their amplifiers directly to the speaker pre-bose amp wires. After googling your amplifier, it does have a "hi/lo" button that allows you to wire it up this way. This way, you ditch the LC2i, and wire the speaker outputs directly to your amp. The sound is 1000 times cleaner and you get a much better punch. From my own personal experience, using any type of Hi-Lo converter box such as your LC2i, degrades the overall level that your sub puts out quite a bit.

Basically take a pair of RCA cables. Each wire that you cut, has 2 wires inside there (+/-). Tap into your left/right and left/right pre-bose amp speaker wires (wire colors and plug access is listed in the link following this). You will be left with just a pair of RCA's to plug into your sub amp. You are done! Others will suggest a different thread from this site, but I am personally fond of this one here that shows you step by step which wires to tap into and it's easy: https://www.myg37.com/forums/audio-v...l-finally.html

In your case, your amp is capable of accepting those high inputs so that you can bypass an hi-lo converter altogether. Any chance you can avoid using those converters, seize that opportunity! They degrade the signal!

In other instances, you are forced to use that converter, but not in your case! Your amp supports both high and low speaker signals.

EDIT: More validation that the converter box you are using is probably the culprit. If you check out the link I posted, the 7th comment posted by gsteigerwald (thread starter), you will notice he experienced exactly what you have described, and ditching the converter solved his bass issue. Including several other happy users that made the same claim in the 5+ pages of that thread.

Also, in your case, you might get a little more extra punch if you flick your button labeled "lo/hi" and make sure its set to lo. If it's not already set that way, that may give you a better response since your telling your sub that you are using the lo input due to using a converter box. If you decide to wire directly and bypass the converter, then make sure its set to "hi" to get the right sound. But regardless of what you end up doing, wiring directly and ditching the converter is the way to go for premium sound.

I have the bose system also, and I wired it directly and it sounds so full and clean with my single 10" JL sub and JL amp after tuning.

 

^This. Ditch the LOC.

You don't mention if you are coupe or sedan. The thread linked above is for a sedan. You can check my Build Thread for info on the coupe.

 

Good call... didn't realize coupe wiring was different from the sedan. Most things on these cars are practically identical.

 

thanks for the input guys! i have a sedan. I will try to ditch the loc and hopefully it will solve my problem. Thanks again!

 

If your loc is still installed try turning up the gains

 

From the other replies I assume you have installed a LOC between the head unit and the sub amp, this is not necessary as the outputs of the head unit are well within the input limits of the amp. You also want to draw the signals from the harness going to the Bose amp and not the sub amp as the signals going to the sub amp are already processed through the larger Bose amp. Better yet, yank everything with the Bose name on it and use it for kindling
