    How Do I Adjust A Subwoofer For Best Sound?

    A sensitivity of 90 db, is 90 db at 1 meter with 1 watt, so 1 meter basically listening position in a car, going 10 x to 10 watts gives you a 100 db, going 10 x again a 100 watts equals 110 db, can't really go up another 10x's and doubling to 180 watts only gives you a just noticeable change in...

    How Do I Adjust A Subwoofer For Best Sound?

    Adding speakers does a similar thing, generally you only do that with subs multiple fronts add phasing issues. Basically getting 10 db louder can also be done by 10 times the speakers and every 3 db by doubling the speakers adding a port also gives 3 db. So going from one seal sub to 4 subs in a...

    How Do I Adjust A Subwoofer For Best Sound?

    The speakers sensitivity is important spec especially for fronts that generally can't handle crazy power which is a problem since loudness (db) and an amps wattaged ain't linear. Loudness is rated in db, 3 db is considered a barely noticeable change in volume 6 db is a very noticeable change...

    How Do I Adjust A Subwoofer For Best Sound?

    A separate amp is almost alway gonna be better and louder than the head unit built in amp, It’s relatively way easier to get volume out of subs than the front end, especially if powering the front from the deck.

    How Do I Adjust A Subwoofer For Best Sound?

    Might take some experimenting then, play songs you know the bass really well and play with it until it sounds right. If some of the notes go missing or quieter then there might be a gap in the frequency and the crossover set too low.

    Kool so yeah just set the filter where it sounds best to you then probably around 80-100 hz. There's probably no filter to the fronts so it is what it is for them.

    How Do I Adjust A Subwoofer For Best Sound?

    That's a low pass filter Do you only have one amp powering both sub mids and high ? If so you might have to wire in passive filters between amp and speakers.

    How Do I Adjust A Subwoofer For Best Sound?

    Crossover is designed to only send select frequency to each speaker, the sub should be using a low pass filter set somewhere between 80-120 hz and if the others are full range speakers (woofer and tweeter in one speaker) then you can use a high pass filter on them set somewhere from 80-120 hz or...

    How Do I Adjust A Subwoofer For Best Sound?

    Phase is if the speakers are in sync with one another, say you got two subs and you wire the positive from the amp to the positive to each speaker same with negatives then both speakers will move in and out together at the same time so in phase but if you wire one sub backwards then it will be a...

    How Do I Adjust A Subwoofer For Best Sound?

    I'm assuming your not looking for overbearing bass, It's been a few years since I setup a stereo, I'd watch some YouTube videos 1st, from what I remember off the top of my head, turn down all the amps gains and turn the sub volume all the way down, turn deck up until it starts to distort then...

    I don't know exactly what you need but it's got to be more than the maximum amps you will draw and small enough to protect the cable you put it on. Here's the 1st chart I found Power wire Max fuse size 00 AWG 400A 0 AWG 325A 2 AWG 200A 4 AWG 125A 8 AWG 50A 10 AWG 35A 12 AWG 20A...

    Alternator recommendations? (and other very noob question)

    You can figure the amp draw from everything and add it up, to figure the size of the alternator, battery is to start your car alternator powers the electronics. Stereo alone can eat a lot of juice, 1000 Watts rms / 12 = 83.33 amps obviously that's cranked and at music peaks. To figure out the...
