Better bass hints needed
I own an 95 EF Falcon, just installed a Kicker Impulse 12 inch boxed sub and a decent 4 channel amp (although not competition quality lol), running from a decent Sony head deck. I'm finding that i do get a decent amount of bass, enough to make the car rattle where it shouldnt, to the point of making the rear vision mirror rattle (on glass mounts) and you can feel it thru the seats. Its not clear bass though, it isnt really punchy, it doesnt sound as clear as it should. And from outside the car, you can hardly hear it at all.
I've tried a number of things, turning the bass down on the head deck and turning up the gain on the amp, and vice versa. I've tried 180 degree phase shift, and changing the connections to the sub.
I've also tried changing the position of the amp in the boot too, i found the worst was against the back seat facing the car, the best somewhere in the middle of the boot (although thats entirely unpractical, facing into the boot against the back seat was nearly as good).
The amp leads are coming from the "rear output" line on the head deck, it has two outputs, labelled front and rear. As i Bias the stereo sound to the rear, the bass gets louder (as you'd expect). The leads go into the low input connections on the amp (the high input are for speaker leads if they need to go into it).
My only thought is that the sub, which i bought second hand from a friend, hasnt been used for a while, do they need time to become more flexible, or should they be good from the word go?
Any help would be appreciated, perhaps I need to accept its as good as its gonna get in that sized car with that amp. I am really chasing a punchier sound, rather than volume. Cheers...
