  4. when choosing a tweeter?

    in Mid's and highs

    Posted

    Yeah I have the crescendo tweets in my door already. I may or may not do it. Depends on how much more mids and highs I need after the box is done

    mids/highs in your sig should easily keep up with 2 15's...

    yeah i wont be adding anything until i put the 1600.2 on them and see how loud they are.

    I have a couple 1600.2's sitting in my garage, sexy amps...

    IMO don't do it. I've tried my HDC's in a 4th and it didn't work well at all. 6th order worked well, but I'm not sure you'd have the room for that in a trunk.

    For a single 15 off a 1200 I'd try to do 4.5cubes net and tune 35-38Hz, should be a solid daily set up...

    Mike I'm doing the build so you know it will be done right. I'm gonna attempt it. I'll do 1.5 cubes sealed in a 2:1 ratio tuned to 45hz. I figured if tys hummer could do it with hds we could attempt it with hdc3s

    I tried my 18's in a 2:1 and they sucked. I've "heard" that they will work if the sealed side is very large, actually larger then the ported side, but I didn't have room to try that.

    GL and be sure to post up how it turns out...

  13. How hard is a recone

    So i got a really unbeleivable deal on an fi btl 18 that i couldnt pass up, however one coil was blown. Im going to recone it and looked up youtube videos, but is it worth taking the risk for my first recone?

    Not hard at all, and only takes a few tools. I've one around 50-60 in the past few years since I seem to recone for everyone in the area.

    Angle grinder with 60grit flap disc & 1/2" wide wood chisel are the 2 "special" tools I use. Figure on a few hours for your first one, especially if you have to solder the leads vs direct connects.

  14. entering first comp....nervous

    Ilovebass, dont worry about thread jack, most my questions have been answered haha.

    The comp ive entered is a db drag and its 30sec peak hold. So is it safe to say i ahould find a song that goes across different freqso it juggles around my peak?

    I spoke to the guys running comp, the said to come early with a test cd and find my peak, then ill have a bank of songs lableled by the the max and min peaks and play a song from there.

    Ia that a reasonable plan?

    What dbDrag class is 30 seconds peak hold? You sure he doesn't mean you have 30 seconds to meter and your loudest score at the end is your score? That would make more sense...

    So you could burp and then try another freq and another one, but your loudest score is what will stay on the screen = peak hold

    Also make sure your batt(s) are fully charged, so no demo's before you plan to meter and let the car run for a while. Also you can rev the motor to 1900RPM while metering which should give you a little more voltage.

    Ideally you'd want to do a sweep to see where you peak at. then burp on a tone at that freq, then higher and lower also to see what's loudest.

    Same if you have to play music, find a song that's at your peak freq or very close to it.

    DbDrag offers burp classes and bassrace which is a 30sec average on music where you have a dB limit you can't go over.

    And FYI, what sounds loudest to the ear will NOT be what meters the loudest.

    Best bet is to get there early, ask questions and watch what others do. Normally there are plenty of experienced people who will help out a first time competitor. And have fun as that will make you want to come back which helps to keep the sport alive...

    I'd meter with the amp set with the DD-1, then turn up the gain more and meter again. You'll more then likely be louder with some clipping which should be fine for a 3 second burp...

    :No: :No: :No: :No: :No: :No: :No:

    please do not do this clipping will in no way make you louder. if any thing u would lose dbs from clipping. plus you risk ruining your equipment.

    :No: :No: :No: :No: :No: :No: :No:

    Where did you read that? Actually it could be louder... Clipping just from gains is a waveform distortion for when an amp is overdriven... Because the clipped waveform has more area underneath it than the smaller maximum unclipped waveform, the amplifier is actually producing more power... but its dirty power... You would be louder but would most likely burn up your equipment doing it. So dont do that OP :lol:

    I know this from experience and a 3sec burp will NOT burn up equipment even if he's running total garbage.

    Makes no diff that it's your daily driver, if you're metering and trying to put up your best number some clipping will more then likely get you there. Then dial it back when you're done...
