[-BenBen- 10+ year member]

I Have a Fi BTL 15, in a ported box (4cu) tuned to 29 hz, and a audiopipe 1800 watt amp, running at 1 ohm. i will get another soon to strap them, but right now i only have one, i got metered and hit 138 at 37 hz. port is on passenger side, seats are folded down. my windshield wipers flex, ears hurt, but its not metering high at all.. any tips for me? i plan on reconing it to a 18 soon as well

try 40-45? Change amps? Turn up the volume?

Tune higher for numbers. Low tuning will sound great but numbers not so easy.

Sealed on dash score? What meter?

You need more power.

What car?

it was a test tone, meter at dash, also pontiac g6, and the gain is at a little under half on the amp. but if i turn it up, it starts sounding distorted. also im not sure what kind of meter it was. i was thinking about tuning to 34, but honestly i want a loud *** daily driver that can be heard real far away.. and i love lows as well so i guess i need to keep it in the lower 30s..and the car was sealed.

build a box with changeable ports. One tuned to 30 and one to like 43

What is the enclosure volume, port area, tuning, and what sub/port position?

Been a little while since I messed with a G6 but I'm sure you can make it good deal louder and still keep it daily.

4 cu ft, 29 hz, sub up, port back passenger side.

it was back, on the driver side but the port was too close to the trunk so i turned is sideways to give it more clearance.

more port and side it away from the trunk lid a little bit.

higher frequency burps. Most cars resonance frequencies aren't that low.

29 is pretty low tuning all around really, I would bet you have a steep roll off rather quickly.

I would try a tuning a bit higher though.

What is your current port area?
