I need a new alt cause im about to put 2k rms in my car. Already found one from excessive- 200A. Did the math for the amps, should be good. He includes diff. guages of wire, I knew I would need that but what guage? 2? He says that it should bolt right on, but is there anything else I need? What about fuses and their ratings? Since this isnt in my area im just going to have my mechanic put it in but I want all the parts ready to go cause I dont think his parts are as cheap as excessive's...

Right now in the ride, I have the new Jeezy in rotation "The Last Laught" and some of the older Jeezy "Can't Ban The Snowman" . If you listen to Jeezy you know it slams. Post yall's favorite mixtapes. Not like homeade mixes but legit ones not like "Prom Night 09"

Alright guys so today i sold my 12" bl and am awaiting my sa-10's. So for now a buddy let me use his little 12" hifonics sub to hold me over until mine arrive. But i honestly dont know what i should do with the subsonic filter now since iv always ran ported lboxes. I have an aq2200 and the ssf goes from 10hz-50hz, so what should i put it at or does it not matter where its at?

i just wanted to know what is the correct way of using oscilloscope to set amplifier gain. 1. Do you scope the amp with the speakers connected? or just hook up the scopemeter to the amp speaker terminal? 2. What test tone to use to set subwoofer amp, midrange amp and tweeter amp? Will 50hz and 1khz be sufficient? I do notice that if i set amp gain at 80hz and then play 50hz test tone, the amp output is clipped. So how low on test tone frequency shall i use for sub amp? 3. For music playback, is it better to use 0db test tone or -3db / -6 db for gain overlap? thanks

hey im new her as well as to making my own boxes. kinda having problems i have a pioneer premier ts-w3001d4 and i want to make a 1.2cu ft vented box. can someone help me out here im so damn lost its not even funny. i want to make it out of 5/8 mdf as well can someone help me please?

I am getting back in the game again! I have never done a trunk build before but had a few 150db + systems before so I'm looking for some answers. I have an 05 Nissan Sentra and I want to do a "trunk wall" build. I want to run two 15s and I want to play some nasty lows an move tons of air and be in the mid to high 140s. I'm considering the Dayton UM15-22 in a sealed enclosure around 6.5 cubes on 2-3k. I'm just curious if anyone have any input on these subs for car audio applications! I am interested because they play very low an they prefer sealed enclosures. I'm just wondering how they will perform in a car audio environment!

I built 2 boxes lately and I will be doing a 3rd soon, and I love buying tools so I "need" a router. I dont want to spend an arm and a leg, but I will spend what is required to have a decent setup(not harbor freight). I want to be able to do speaker hole cut outs with it, round the edges of the box and ports, and anything else that is usefull. Im not sure what bits I would need either, I was thinking 3 one to make cut outs, one for rounded edges, and one to flush mount on a double baffle. Also I think I need the jasper circle jig unless there is a better/cheaper alternative.

What about this one??? http://www.extech.com/instrument/products/...450/407732.html

Ok i am bout to purchase my first audio system. but i had a quick question. Is it really neccesery to purchase Component speakers and a Amp for them. Or can i just use my Manufacture speaker.... If i Just use my manu facture speakers. Do i Just run them to my head unit or wat

I have always wondered about some of the lingo used on these forums when it comes in competitions... Anyway what is a Bass Race vs a dB drag? Or a SQ event? How are they measured? I am sure I missed a few different race names but what are they? How are they all different? How are they measured?

hi all went up to a local truck shop the other day and found a demo for a truck liner which consisted of a few pamphlets and a coke can covered in bed liner, well a friend of mine and i started playing with this can and soon enough we were breaking a sweat trying to crush it. then later that night i was watching my truck as the fi q 18 i had in the bed played and i saw how much everything was flexing so i was wondering if i coated the inside of my truck with the bed liner if it would save me from running into a problem like iamanmp3pimp (sorry if i butchered the Sn )had with his roof flexing till it cracked. thanks

i did some repair work on a truck, the guy had it installed a few years back at a place in austin that went out of biz after year and years of serving the austin tx area, anyhow.. they had a rope, that went from the highs amp, up the head unit.. so that you could just tap into the factory door speaker wires from the harness, inside was of course 2 puple 2 white 2 green 2 grey. and a remote wire blue, all inside one rope the size of 0 gauge, i wish i would have remembed the name of the company planly printed on the can casing, but i dont, has anyone ever seen this ? and ya know where i can get a bunch? thanks,

do you trust buying alternators parts from Hex autoparts? please forgive if this is posted elsewhere

ok so im pretty much a newbie to the audio world i have a 1996 jeep cherokee with only front door speakers and i have bigger alt and bat, and i listen to rap, metal, country, everything, and i want a nice sounding system, i will need a deck with aux port, and speakers that sound clean and clear, and a single sub, i dont need to break windows lol, so if you guys have any suggestions let me know, i would like to keep it under $900. thanks

Drivers side ... enough room for the mid right where the foot rest is, may be enough for the tweet too. Passenger side ... plenty of room for the mid in the area right by that plastic bolt. Paper template baffle in place. Similar to real life size (tweeter would be moved closer to the mid). Drivers side. Drivers side again. Trying to show where the mid could go. Passengers side ... looks like barely enough room if the tweeter was moved up. Closer view of passenger side ... should be ok on this side if I move the tweet closer I guess. Spring project ... fiberglass box for the (Magnum D2) most likely. Should turn out ok. If it turns out that there is too much air…

everything i'm putting in my car now will be taken out within a year to be put into a new car (crosses fingers) my question is if i put re comps in do would it be worth all the effort. i know it will sound great. but i already know they won't fit in the doors so i'd have to have somthing custom made. if by some miracle i could get them to fit in my car would it be necessary to deaden? car is a 94 pontiac sunbird,,, upgrade car will be 99 eclipse just comps. new battery. another amp. 0awg wire. and big 3 left

Just out of curiousity, what is wrong with a particular signal if it is clipped?

so i have been searching around for a solid definition and i cant find any so any help would be greatly appreciated

When is it, where is it, and how much is to get in.

I saw a Alping IVA-W205 for $415 locally and It includes the wiring harness, Ipod cable,box,all manuals,DVD while you drive relay and two remotes. It was supposedly only used for a month. I have been looking at getting a new HU for my next setup when I get a new car and was wondering what you guys think of this double din touch screen or if I should just stick with a single din that would be cheaper? My goals are just to get good SQ from the HU and I want blue-tooth, so any other options would basically be a bonus. I will be doing the big 3, amping front stage speakers and then have a sub in the back.

Custom Cherryman box, 1.6 ft3, tuned at 34, wired at 1ohm I'm deciding between a new IA10.1 for $390 or a gently used SAZ 1500D V3 for $360. I know the SAZ is under rated but I cand find any bench test results on the IA10.1. Im imagine the 300 RMS between the two amps cannot be heard by the human ear. Would there be any difference in SQ between the 2 amps?

All of the sudden my amp took a chit on me and whatever I hooked up to it just made this noise http://www.mediafire.com/?e9y93yxto0l any idea whats going on? thanks O and this all happend the night before a competition i prepared so long for it sucked ass any help is appreciated

does anybody know the rms on the 15inch l7 kicker 2005 model

I'm looking for a tool that will allow me to cut the holes for the speaker, the terminal on the side and also some sanding to smooth the edges. If someone could point me in the direction of some affordable drill attachments and sanders to finish this job, that would be awesome! Thanks, Mo
