I just found an alternator on ebay, and im not sure how much of an upgrade it is, but it definitely is one... http://cgi.ebay.com/ebaymotors/_Car-Truck-...bayphotohosting Most likely 165 is its max, with a lower idle. Im not even sure what my stock alternator is I want to say 85A, I have big 3 with 1/0 and with my 1500 watt amp with moderate gains I drop to 10v or so under heavy pounding, with severe dim. Is this alternator an adequate upgrade, or should I save up and hunt down a slightly better one... I dont think i can afford more than $200 however. If I did get this do I need any other upgrades? My batt is stock btw, but with a good alt is a better one needed? By needed I mean worth the cash since I am virtually broke right now...

i have 1/0 big three and when pushing hard with 1500 watts i drop to 10v, Ive been saving for an extra kinetik and then assume ill be fine, so to halfway answer your question... most likely you can do 1500 or so

lol wow that l7 is so stealth! Anyone know which can get louder/handle more power when comparing the dd 1508 to to ss rli-8? I dont know any other beefy 8's between 150-175, and I cant tell which can handle more/get louder

LOLOLOL that one about killed me john 5k daily??? you gonna have like 6 of them and blow things up?

Thanks for the tips The comp is just at a local store, so anything goes for rules pretty much, and im gonna try to get my current box as loud as possible.. the only mod I can think of without tearing it apart is to 45 all the corners by cutting the pieces and fitting them in through the sub hole and putting them in place, which should raise me 1 or 2 hz. Last time I had it revved up some, lol the guy that tied me had a focus with a fart cannon and he was bouncing of the rev limiter it sounded so bad... all I can figure is his box is horrible if he has two ten inch solox's and 3000+ watts and tied my low tuned q... but it would be awesome to win especially since I just ordered an fi shirt and no one in my town knows about them.

darn internet lag double posted...

sorry i guess it would help to say its a honda accord, so midsize sedan, with the mic in the windshield on passenger side, and its outlaw so windows can be wherever is loudest

I have absolutely no clue how to use round/aero ports, im assuming you mean have two sets of the same diameter but varying lengths for different tuning? how do I tune those I've only ever used RE's calculator... also the owner of my local shop said its louder facing the trunk instead of into the car because of what i think he said was "quarter roll effect" does anyone know anything about this?

definitely buckets lol, its a huge accomplishment to fit this thing somewhere with a bench seat...

lol when you live in a 4 bedroom apt with the only car there is not backseat/floor space I had it sealed when I first got it running at 4 ohms so only 800 watts, i still have the box maybe ill throw it in there at 1ohm and if I really like it ill keep it, but 2 rl-i8's are so appealing just for the wow factor and a ported box for them is smaller than mine sealed. My town is also huge on kicker so to everyone i know my sub is GOD, so I can easily get 375 for the sub and the box I have it in, so all of my options just hurt my head and its nice to get others opinions.

to be more specific with my center console box... port goes behind passenger seat... I was weary of this design at first too for acoustical properties, but blowthrough was not an option so this was the only choice. I personally think it sounds amazing, a great output with very even response, and the bass is coming from everywhere you cant hear it 10 inches in front of you or right behind your seat(as the passenger)... its just there p.s. amazing system thumper

Yea i was trying to avoid building an spl only box, and hoping to just upgrade this/fine tune things as much as possible. In this box I peaked at 36hz, so im thinking 38-40 would be ideal for spl, but again I dont think I want to build another box... what is an average spl tuning in a mid-size sedan, if there is an average?

So last time I entered an spl I tied a guy with two 10" solo x's and a rockford fosgate t3000, and there's another in 2 weeks and im sure he will be there. I dont want to risk damaging my sub by upping the gains or voltage any more than i did last time, but perhaps i can adjust the box/ place it in my car differently? The box is a little over 4^3 at 31, and it is about a foot back in my trunk facing into the car. Only ideas i have now are putting 45's in my corners to help flow and raise tuning, and face the sub towards the trunk. Are there any little tricks anyone knows about to give me just a .1 or .2 db gain?

I liked it sealed, but the extra ported volume i like. Im not specifically refering to the q but any sub in general, or is this too far from being able to generalize?

So I have a 15" fi Q with a 1500 watt clarion amp in my accord, but im looking to trade in the q for something else. I can not afford a new amp, or any electronics upgrades, so 1500 @ 1 ohm is my max power. Im tired of the q because i have almost no trunk space right now and it makes grocery shopping for 3 or 4 people kind of difficult. Im not sure if it would sound good in a 3^3 ish box but FI says it can be from 2.8-4, but something new is always fun so ill probably switch out. I want to stay as close as possible to as loud as I am now, and want it to sound even from low lows to higher lows...(my 45-60 response is rather weak right now but i think its because its a 4^3 box at 31hz) Subs i'm considering: 2 10" fi ssd's 2 8" soundsplinter rl-i8s if they ever are in stock again(very small box and lots of wow factor) 1 underpowered 12" btl 1 12" bl with some beefy options I dont want to spend more than 400, and id like the final enclosure to be 3^3 or less. I noticed FI recently lowered prices which makes them even extra appealing :bigclap: Ive never heard any of these before, and dont know much about other companies, and am basically looking for input as to which setup can potentially be the loudest while still sounding good, or if you think my q will sound good in a 3^3 box. please and thank you for replies.

Sorry if I was rude, I just want to know if anyone has experience with the same sub in a smallest vs the largest recommended enclosure and if that affects how even the sound reproduction is, I am not aware of a better thread title or section to post this in.

I love these designs and kerf cuts!!! I would love to try something like this sometime... how do you measure for the kerf cuts to come out right, and do you just add an inch or so to port length to accommodate for rounding the end of it?

does anyone have a guess or sheet saying what the 1600 puts out? imy brother just got one and im curious what hes actually getting... its much louder than his alpine 400 and sounds as good, i just dont want him thinking he has 1600 watts but i dont what he actually has, how do you use a dmm to measure output?

the 12" q has been tested up to 1600 watts easy, 1800 for a burp is the highest comfortable power, the 15 is either the same or more, so i wouldnt feel bad hooking a brutus 1600 to it and giving it probably 1200 or so watts with reasonable gain, however like everyone else is saying hifonics isnt the most reliable amp.... but theres a warranty so its really up to you, if you want straight budget the brutus isnt that bad

i understand m5 knows a lot, hes on the tech team, but that doesnt merit rudeness and i think my question is legit along with my title and section

that doesnt change anything, i asked a very specific question and would like an answer to it instead of some rude person coming and saying "readress your question because your an idiot." all i want to know is if min/max box size affects the evenness of sound output, if you cant answer that then dont post at all please and thank you.

i wonder the same thing, i always thought you should fuse alt to bat + since in most stock vehicles it is fused, so obviously it serves some purpose, but ive heard a lot of people say they dont...

i dont see how i am misusing the phrase sound quality in reference to the quality of sound of a sub/box anyway how do you define sq, and what am i asking about then?

So i know hifonics isnt the best of companies, but ive heard mixed opinions about the 2008 brutus amp lineup as to whether or not it does rated power, I was wondering if anyone knows for sure what they output(specifically the 1608) or has any birth sheets/ done any bench testing. If not what do you think the bxi1608d does at 1 ohm and at 2 ohm, it claims 1600 at 1 and 1100 at 2...
