Subwoofer and Amplifier?

Question

I currently am using a Rockford Fosgate P2 Subwoofer 500 Watt and a Lanzar 1000W amplifier. The subwoofer is current bridged to obtain max power. On my amplifier though, what settings are the best to obtain the best sound with less distortion.

The settings for frequency are LPF - Full - LPF

I have a Level setting which goes from MIN to MAX

HPF that goes 80hz to 2.5K

LPF that goes 35 HZ to 400

Bass Boost 0 - +18dB

Phase 0 - 180

what are the best settings for this amplifier?

Answer 1

"what settings are the best to obtain the best sound with less distortion"

distortion is the main cause of sub damage

CEA-2006 Compliant

On May 28, 2003, the Consumer Electronics Association published standard CEA-2006, "Testing & Measurement Methods for Mobile Audio Amplifiers." This "voluntary" standard advocates a uniform method for determining an amplifier's RMS power and signal-to-noise ratio. Using 14.4 volts, RMS watts are measured into a 4-ohm impedance load at 1 percent Total Harmonic Distortion (THD) plus noise, at a frequency range (for general purpose amplifiers) of 20 Hz to 20,000 Hz. Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. This applies to both external amplifiers and the amplifiers within in-dash receivers.

CEA-2006 allows consumers to be able to compare car amplifiers and receivers on an equal basis. Manufacturers who choose to abide by the new standard are able to stamp their products with the CEA-2006 logo that reads: "Amp Power Standard CEA-2006 Compliant."

so.......CEA-compliant means that the amp has been tested and produces or exceeds the advertised RMS wattage with MINIMUM DISTORTION

Lanzar is flea market grade, mediocre at best, very over rated brand, you would be lucky to get half of the advertised RMS wattage from it (underpowering is the second cause of sub damage) and it would be distorted

i said all that to say this- they best settings for that amp are setting it in the trash

you need to buy from CEA-compliant companies

Alpine

Bazooka

Blaupunkt

Clarion

Eclipse

Infinity

JBL

JL Audio

JVC

Kenwood

Kicker

MTX

Pioneer

Polk Audio

PPI

Answer 2

A lot of those settings truly dont make that significant of a difference.

Obviously, you'd want to move the bass boost up to as high as you want the sub to put out.

I have 3 12" JL w3s with a 1000/1 and I use 80 hz HPF. Ive also tried 120/125 and it sounds fine too. Either one should be fine.

You're LPF and phase settings are simply obsolite and unnecessary. Phase tells the amp when to go into overload/protection mode. But with a Lanzar amp, it really isn't going to matter.

good luck

Answer 3

first off you wrote(The settings for frequency are LPF - Full - LPF) i think you meant LPF-FULL-HPF

set that to low pass filter.(lpf)

your level is probly your gain set it to almost max

hpf doesnt matter (unless you select it instead of lpf)

lpf i perfer around 65-75 hz

bass boost the louder you want it the higher you set it

phase keep at 0

Answer 4

whatever you do done use bass boost. that distorts everything. 100 HZ is good for lpf, not to much or to little

Answer 5

First of all Lanzar makes very poor quality products. you should get a better amp. lanzar is known for overstating their ratings.

next LPF stands for low pass filter. it cuts the power on bass signals below a certain frequency to prevent damage to subwoofers. if you have a ported enclosure than this is a must. if you're using a sealed box then its not as essential.

HPF is high pass filter, which shouldnt be on a subwoofer amp. it is for the higher frequencies. which shouldn't be played through a subwoofer.

bass boost is self explanatory - but caution turning this up too high will clip the signal, and clipping causes burnt voicecoils

phase has to do with the subwoofer setup.

the best settings would be to have the low pass filter a little bit lower in frequency than the tuning of your enclosure (if its in a ported enclosure). if you're using a sealed box drop it all the way to 35 hz so yo don't miss out on any bass

high pass filter should be as low as possible

bass boost is up to you, just turn it down if you smell burning.

phase - unimportant
