Bass4Lyfe Posted November 17, 2007 Report Posted November 17, 2007 Okay so for a few months now I've had 2 12" subs .... in a stock box in my trunk of my big fat SUV. My question is (and I realize this is easily tested, I'm lazy & it's late), does placement matter? So like if I move the box (and subs) really close away from the rear of the car, like half a foot, will it be louder? The reasoning is that the sound would bounce off the wall and reverberate into the cabin more. OR Do I put them as far away as I can to get more "air space"? As you can tell I'm very much a newbie! Haha Right now I have 'em placed somewhere in the middle ~Matthew 1998 Toyota Camry XLE V6 3L (1) ScyTek Astra 4000RS-2W-1 2-Way Remote Start Alarm with Shock and Proximity (1) 20% Tint All Around (Gately Audio) (1) 250 Amperage HO Alternator (1) Big 3 Done In 1/0 (2) Kinetik HC2400 Power Cell (1) Alpine IVA-D106 Receiver (1) Peripheral Video Bypass Device (4) Alpine SPS-17C2 Speakers (1) Alpine KCE-422i iPod Control Interface (4) Sheets Dynamat Extreme; for speakers (1) 10 Square Feet Hushmat (Trunk & Rear Deck) (4) DC Audio Level 4 15" D2 Subwoofer w/ Level 5 Coils (1) Wall Built By David, Tuned to 32 Hz (1) Rockford Fosgate T40001bd Amplifier (1) Stinger 1/0 Wiring (2 runs of + 2 runs of -) (1) Stinger Volt Meter

XtremeSPL-SCAMMER Posted November 20, 2007 Report Posted November 20, 2007 bump rule of thumb is if you have a hatchback, you want the port facing the back of the car . in a trunk, you want the port facing the front. in a tahoe, yukon, blazer, explorer anything that is like a hatch, you would do the same.. as far as louder and placement goes, i dont think it matters.. i had my port right next to my hatch, and it was loud enough inside.. i tried to move the box, and test that out myself, but it was the same.. but it was 2x louder with the port facing the back, than port facing front.. it was that big of a difference... i say test your self.. see what you think.. if you live by someone with a termlab get on it, and make your changes.. change one thing at a time, not all at once... IM A LOW LIFE SCAMMER SO I WAS BANT....TEH HAMMA is NOT my friend

Derrick824 Posted November 21, 2007 Report Posted November 21, 2007 I've done testing in my Yukon but its not the XL so my cargo space is smaller. The little bit I moved the box from front to back made no difference for me.
Bass4Lyfe Posted November 21, 2007 Author Report Posted November 21, 2007 okay, great. and your subs are firing towards the rear of the vehicle right? thx ~Matthew 1998 Toyota Camry XLE V6 3L (1) ScyTek Astra 4000RS-2W-1 2-Way Remote Start Alarm with Shock and Proximity (1) 20% Tint All Around (Gately Audio) (1) 250 Amperage HO Alternator (1) Big 3 Done In 1/0 (2) Kinetik HC2400 Power Cell (1) Alpine IVA-D106 Receiver (1) Peripheral Video Bypass Device (4) Alpine SPS-17C2 Speakers (1) Alpine KCE-422i iPod Control Interface (4) Sheets Dynamat Extreme; for speakers (1) 10 Square Feet Hushmat (Trunk & Rear Deck) (4) DC Audio Level 4 15" D2 Subwoofer w/ Level 5 Coils (1) Wall Built By David, Tuned to 32 Hz (1) Rockford Fosgate T40001bd Amplifier (1) Stinger 1/0 Wiring (2 runs of + 2 runs of -) (1) Stinger Volt Meter
Derrick824 Posted November 21, 2007 Report Posted November 21, 2007 okay, great. and your subs are firing towards the rear of the vehicle right? thx When I had my 12s they did better with the subs and ports firing towards the rear. Now with my 18s its totally different. They hit louder down low in the 30hz range when firing towards the rear (as seen in my avatar) bu they're 1.5db louder at my peak of 41hz with subs firing up and port back. However after firing the subs up I lost 1.5db down low in the 30hz range. Subs & port back I hit 145.5 @ 30hz and 146.5 @ 41hz Subs up & ports back I hit 144 @ 30hz and 148 @ 41hz
