Loss of bass

[Gooch89]

Hi guys, having an issue with my audio in my 2006 wrx. I have sound deadened my 4 doors and boot(trunk). Installed jbl gto splits front (6.5") and rear (5.25"), powered by a 1000w pioneer amp(have correctly set gain). I also have a 10" kicker sub on its own amp. The headunit is a grundig. Now the issue I have is, when driving I loose a considerable amount of bass. If I lean forward and down to where my steering wheel is whilst driving I can hear the same bass heard whilst stationary. What am I missing here? Why can't I hear my bass in the correct seating position.

Have you tried changing the position of the sub or the direction it's facing?

I have tried it laying down with the woofer facing up. It's currently facing towards the rear of the car.

Update, spent some time messing around and set the time delay for the subwoofer to a much longer amount. Also inverted the phase of the woofer. Bass is has improved by a great amount. It appears that the sub was cancelling out the door speakers bass.

At least you found a way to get more out of it. What type of enclosure? Sealed or ported? If ported.. what is it tuned to? Which Kicker 10" sub are you using . Are you running a 1 ohm or 2 ohm final load? I know that C10 SCV 4 are prob kind of old, and may not have changed much. But back in the past, I put 4 Kicker C-10s in a 3.6 sealed enclosure on an old Autotek Mean Machine 66HC in a cousins 78 single cab Chevy truck and they Slammed!!

It's one of these bad boys. Comes as a package. I believe it's a ported box.

This is only a 150 rms sub. I havent found what it is tuned to. I would recommend looking at a mininum of a 600 rms sub up to 1k rms @ either 1 or 2 ohm and an amplifier to match with a ported enclosure tuned from 32-35 htz with sub and port facing rear of trunk which generally yields great result for trunk placement. Others may chime in
