Subwoofer gets noticeably louder

[venoxcide]

Hi all,

So it's been about two weeks since I've done my audio install, and I've had lot of help from the people on the forums, so thanks alot!

My setup is:

Pioneer DEH-X6600BT Head Unit

Pioneer 12" TS-W304R 4 Ohm 300W RMS Subwoofer

Pioneer GM-D8604 1200W 4 Channel Amplifier

JBL 6.5 Coaxial 180W Speakers

I did everything myself and to the best of my ability I have set the gains on the amplifier by ear using a 40 Hz test tone for the sub and with the loudest music I could think of for the speakers so I get no distortion up to 50/62 on the radio (I believe it distorts at 51 according to research).

I play my music at around 40/62 for a really good balance of loud, impactful bass and strong mids and highs, however lately, and seemingly randomly, the subwoofer is alot louder. It's shaking the car a lot more, and the bass hits are much more impactful.

I've only noticed this the past few days. Today was a good example, I drove to work playing my music at the normal 40/62, however when I was leaving to come home, the sub seemed to all of a sudden double in power, and I was driving home at around 25/62.

I wish I had a decibel meter so I could measure if I'm going crazy or not, but it's just something I've noticed.

The door speakers are on the amp too but I don't notice them getting any louder than normal, it's just the subwoofer.

Any ideas on what could be the issue or am I going mental?

My first guess is that perhaps the RCA I'm using for the sub is broken, so I'll be checking this first thing tomorrow.

Any other ideas?

Are you running the sub off the 4 channel?

Are you running the sub off the 4 channel?

Yeah, I have the door speakers on channel 1 & 2. Channels 3 and 4 are bridged for the subwoofer.

YOur ears can do some weird things sometimes. Also, the sub will get louder and louder until it is fully broken in.

Just to give an update incase anyone was curious, seems the subwoofer just got louder.

I double checked all my wiring, and the amplifier and everything is good.

Made sure to recheck my gains also but they are set properly. No clipping or distortion...I guess the sub just got broken in a bit.

yes, that will happen as they break in ...
