I still haven't learned a lot about tuning boxes, and normally pay someone to do it or use free box generators. I am likely going to have to build a box with the port extending outside of the box. Is this going to affect tuning? Say i need a 18" deep port in the box. If I just move it out, 14" inside and 4" outside, will this affect tuning?

okay so i live in the northern illinois region and i was driving south into rockford illinois to take my friend to visit her boyfriend, who is in jail. so as im driving us to the jail, a cop shows up behind me, so i kill my system. cherries go on, and i get pulled over. so cop comes up to my window and asks me if its me with the loud music and i lie, and tell him no. and he goes, "pop your trunk". so i tell him no, u have no probable cause. and then the cop says yes i do, i heard it coming from your direction. so thats when i roll into, "o, well low frequency sound is omnidirectional, so actually you cant tell which direction its coming from." so then he gets all pissed a…

So I moved into my dorms for college today, I figured I should check out the town and look for any audio shops. I found one that used to carry RE products, but now mainly KIcker and Memphis it looks like. Anyway, I looked around the shop and found an RE 12 RE series, and a Coustic 321qe. I managed to get both of them for 230, Both BNIB. Anybody, think I got ripped off or was this a great find? Also, the gain knob of the front channel seems to be stuck, any ways to fix this?

I plan on gettin either a Stetsom 11K2D or a Stetsom 14K2D. I was going to buy about four or five kinetik 2400's but I seen this battery. Is this ONE battery "Strong Enough" to power a Stetsom 11K2D or 14K2D all day everyday? Battery http://www.batcap.net/Products/BatCapProdu...91/Default.aspx

My buddy drives a '00 frontier with a jvc head unit with aux. His 6 3/4" door speakers are blown so they are disconnected and the only speakers he had were the stock tweeters in the door. He got in the truck and no sound was coming from the tweeters. Tried CD player, aux, radio and nothing. Were thinking the tweeters could have taken a dump or the head unit is poop, or maybe a loose connection somewhere? What could this be?

Thought I'd let you guys know, I am working on a small side project. Only a few days in, but I think it could have some potential when there is a ton of information. It's going to be the best exotic car collection on the web, with everything you want to know about any Lambo, Ferrari, BMW, Aston Martin, etc.. I am posting here so you guys can help critique me. This address below is only a place so you can see it for now, it will be moving to it's own .com later. logos, etc are coming in the future.

I have a couple questions about setting the gain, and the settings I should be using on my head unit. My setup is a IDA-x100 headunit from alpine. (Pre-Amp is 2volts) My subwoofer is an 15" Q, and amp is a SAE-1200 Sundown. On my headunit, I heard that the subwoofer level should be set to full, 15. But I didn't know what to set the base level at, so I just set it to full, 8. Then I tuned it to 36volts using a dmm, (Thats what the tuning instruction sheet that came with the amp said to tune it too) It sounded good, but I feel with that much power, I should be getting it a little louder. So I put the bass to 0 on the headunit, but then I could turn the amps gain up to maxim…

hey whats up i have a 94 ford econoline van, i was hit ting 138.3 in it, and i had 3 12" kicker solo barics, with a kicker 1500.1 amp that was ran to 2.6 ohms so i was gettin about 1000 out of it, i just recentyl installed 4 15" solo's and a 2000 watt sundown that will b ran to .5 ohms, with a 13.3 cubic fot box, im also installing a second battery, how much do u think i wil gain

well i went to connect the positive run of wire and as i started disconnecting the battery the alarm kept going off i went ahead and finished disconecting the battery then connected the positive run of wire then as i was reconecting it the battery the alarm started going off again then i tightened it all the way then waited for the alarm to go off then i tried to start the car and only the battery will go on it wont click or anything when i take the key out the alarm beeps what do i do?

So a friend told me about line drivers and i was wondering should i be using one? is the advantage they offer that great? and why would i need one? like if i run a dmm over my rca and they are getting around 1volt should i be using a line driver to help out my rca so i don't have to turn my gains so high? also do i need one for all my rca's (fronts, rears, subs?). also do yo use one? And if you do use one which one do you use? Kenneth

Ive got an ssa xocn 15d2 run off of a sundown saz1500d. It was working fine for about a month and then all of a sudden it stopped playing, I turned my truck on one day and nothing. Then about a few days later it started playing this weird static and soon was working fine again. But as of 3 days ago its not working and playing the static again. Ive replaced the rcs and the headunit and its still not working. I have no idia what to do now any ideas??? Here's a vid of the sound its making .

Hey guys! I drive a Ford Expedition and I pretty much made up my mind on my upgrade. Now I have two Diamond Audio d6 components in the front and two d6 coaxials in the rear powered by Diamond Audio d3 500.4 amp, runing 4 guage power and ground wires to the amp. I currently have two Diamond audio d3 15 inch woofers powered by Mmats 2000.1. I want to replace the subs with four Ascendant Audio Havocs and having two Mmats 3500.1 powering them or should I get two 18's instead with one of the Mmats amps powering them. The box is going to be ported tuned at 32hz. I'm more into sq but I also want to feel the bass in my bones when I need to lol. I listen to a wide range of music. …

I was wondering why subwoofers use tinsel leads to carry the current to the voice coil. Wouldn't copper be better because the resistance to electricity flow is lower? What makes the tinsel leads better for that part of the sub.?

Hey guys. Im in the process of upgrading my system in a 2002 Ford expedition w/o the third row seat.

I'm buyin four Ascendant Audio Havocs 15's and two Mmats 3500., So my question is I would like to know whats the Ideal enclosure specs for the woofers in an expedition for great sq. I want a ported box, So if anyone have any ideas or can answer my question I would greatly appreciate i…

Alright, I plan on running 1100w-1200w RMS to an 18" woofer so I am torn between all 0 Ga wiring or using a 4 Ga amplifier wiring kit. The 4 Ga kit I'm looking at it rated for 1400w but I think 0 Ga would be better. Also, the amplifier I plan on using only has 4 Ga terminals for power and ground - would it be safe to trim down the 0 Ga and put them in 4 Ga terminals if I were to use 0 Ga? Amp is: JBL GTO 1201.1II - 1114w RMS at 2 ohms Woofer is: IA DR 18" D1 Thanks in advance! -John

so, was at the junk yard today getting some parts for the Saturn (need a new trunk latch) today, when I spotted this odd looking by-nine on the rear deck of a caprice (old 80s box chevy) right? so after I got my part and my bolts needed, I walked over to the caprice and took a peak in the trunk, found about 15 feet of 8AWG wire (perfect length for the application I need it for, no, im not using it as power wire) in the trunk, and then I looked at this yellow by-nine that I saw, the magnet was BIG, had to be atleast an 80oz magnet, mags as big as a CD in diameter, couldnt find the second one, so i grabbed it and continued to look for other parts. later on today when I got …
