I know it's something I did. I have two big flaws and it's got to be one, just asking which one you guys think I should fix first (low funding!)

04 Maxima - Stock HU - Bose System

I added a 1100w Sony amplifier, and two 12" Alpine Type-E's. I only used 8ga wire, which could be the problem, I know I should have used at least 4ga. The second thing is, I spliced into the output for the rear stock subs, and stole some input from that, and then ran it to the amp. I know it has to be losing some signal from this - but I suspected the power wires' low gauge before the input.

What do you all think?

 

i'm guessing it's the latter. recheck the splice and see if they're secured. maybe the bass is making them sporadically connect. the 8 gauge will work fine for awhile since i don't really think that sony amp is putting out over 1kw of power. but i'd definately upgrade to 4 gauge.

 

Would a high-low converter help ya think?

 

My stock Bose sub does the same thing...When it wants. Mystery..

 

its probably your remote wire to the amp. Turn it up to the volume where it cuts in and out, and go back and look at the status light on your amp... is it your amp turning on and off, or JUST your subs?

If its your amp, tag an accessory wire or something under your front dash and run it all the way back to the amp.. its a pain in the @ss, but it wont cut out anymore..

btw, same exact thing happened when I was at work and installing a sub/amp in a new Civic Si (stock HU as well), we used a voltage trigger to trip the amp (from the stock rear speakers), and it would cut out at higher volumes. good luck.

 

When you are using a high-level input, which you are doing from tapping into your speakers, you cannot crank it as loud since i'm assuming you are using one of the power wires as a remote wire also. the 8 guage wire is fine since a 4 guage wire allows more power to the amp therefor making it only louder and will not shut off the subs even if you use a 12 guage wire with volume all the way up.

Do this and you will know what i mean. Run only one sub by taking off the connection to one of them. Now crank up the volume. It should still be bumping. You're going to need an aftermarket head unit in order for your system to run decent. You're drawing too much power from your speakers therefore your amp is not pushing the right amount to your subs. That little wire from the back speakers will not cut it.......

 

Perfect, thanks.
