Technical Info & How To's

So im helping my buddy hook up his little system but ive come to a blank.. he wants an amp for his sub then an amp for his speakers. ive done this type of installation only once and i think i got lucky but ill get to the point, um how do you wire two amps in one car ? so to my knowledge, pos and neg from battery to distribution block, then two pos and neg to the two amps. right? for the headunit im also a little confused, both amps only have inputs so how do i split the rcas? im guessing some type of wire splitter for those and both amps have two inputs? and for the remote, do i use a distribution block for that or is it possible to put it in one amp and then to the o…

hey guys does anybody know how you would wire this qvc beast? I know you would take a pair of the voice coils and wire them to an amp. So im guessing you would do the same to the other side. Heres my question, when wiring separate sides of the speaker to its amp would you wire as you normaly do or is there a special way? IM goin to put one amp per pair of coils, i just want to make sure i get 1ohm power from each. so would i just wire each side to 1ohm or is there a special way with a qvc sub?

I've watched over and over on YouTube how to wire two batteries in a car. I'd have one as my main starter battery and one in my trunk. Do I just have the positive from my main battery go to the positive on my second battery? (fused of course) and the negative just go to the ground and I'm all set? And another question, having this battery setup, will it put more stress on my alternator? Thanks I appreciate the help.

max dimensions are as follows: 16.5" tall x 39" wide x 19.75" deep. I really need some assistance been working on this for 3 days and am getting no where.

So I failed to mark the ground terminal on my Dynaudio MD 100 tweeter when I took it apart as I want to paint the surround black (don't care for the grey). Now I find that I can't tell which is the '+' side as the speaker will go back in either way and the posts are identical. I took it's twin apart more carefully but find the opposite terminal was '+' on it's surround case. Now I'm more confused than usual. Are these tweeters not phase sensistive?

Hey guys I have never installed HIDs before and I was hoping someone here could help me. I looked up what kind a 94 toyota 4runner needs and they say Its 9004 so I ordered a hi/low kit from ddm tuning. I figured out most of the shit of the install pretty Simple theres just one plug I can't seem to find a place for. I am guessing it's what tells the lights to go on and off from the switch. Here's a pic of the plug in the instructions that don't come with it that you have to go to their website for say it should just be hanging loose somewhere, but i can't seem to find it. Link to download instructuons Where would I find this? Is this even the right plug for it? Any help …

I am building a small sub box for my 2001 S10 ext cab ZR2 using a shallow mount MB Quart driver. I'll be mounting on the rear wall of the cab. Anyway I pulled off that rear wall panel and discovered there is a cavity where I should be able to do some good in terms of sound deadening and wondered if using regular spray foam found at home depot will actually do some good? Is it dense enough to stop sound or should I be thinking about another solution? Mind you I'm just looking to have it better than it was to cut down on road noise since I've got that area opened up...not looking to spend a lot of money or have to order more products in.

Can anyone give me some ideas on fixing these cracks in my car's trunk floor? I'm aiming to get a good seal so it won't leak and for it too not crack again once I put my sub back in. Oh and I'm trying to spend as little money as possible so I could use some cheap ideas. I appreciate any input. Goes past the deadening to where my finger is.. And then there's this..

Power compression is a topic that is rarely discussed, but always important. When you hear someone call various theile/small parameters a “small signal parameter”, the implication is that with larger signals (more power), there will be a shift or change in these theile/small parameters. This is what we call power compression, and occurs in 3 potential ways. The first thing to consider is how theile/small parameters are derived. There are 5 basic parameters from which all other data is extracted. These parameters are Re, BL, Mms, Sd, and Cms. So looking at this from a mathematical standpoint, a change in any of these parameters will cause a change in all other parameters a…

Well guys maybe one of you can help me out. I have/had in my SUV a Tc sound axis 12 and was playing it on my orion 275rhcca amp at 1ohm and it was slammin UNTIL it started to rattle So after i removed it from the box i noticed that the whole spider assembly came unglued from the basket/spider landing . Now this is my question I'm sure that its covered under warranty but what are my chances of reglueing it my self? It's not about if i can do it but rather will it be worth it in the long run so to speak. I don't think it will be a problem aligning the coil as it seems to rest snugly in one spot where the LITTLE bit of glue originally was. I have a pair of them and I'm …

i am looking at getting Two Sundown Audio SA-12 D2s and i am wondering if i should get them 4ohm or 2 ohm and i was wondering if there are any amps in the 200$ price range that can power them good to make them hit. they will be in my single cab GMC sierra and i am wondering if anyone has heard these subs and if they are LOUD i am looking for LOUD pls help me!

hey guys im kinda new to wiring subwoofers so i need some help. i hear now a days people are using these speaker pins and banana plugs to wire up there subwoofers, how do you use both of them? and which one is the better to use? one more thing, what gauge wire would u use to wire 2 18" fi btl's? thanx

It has been debated rather hotly for years, and now it has become pretty much accepted that MP3 and sound quality do not mix. But why is it? Why do some people hear so much loss in their systems and others don’t? Are my old ears really better then someone 30 years my junior? Someone who still has a large amount of their hearing range left, while mine has deteriorated over the years should be able to hear these losses better then I! I started with home tower speakers in the back seat of my old Delta88 back in the days when we had no real systems, and we still had post mounted tape decks and 8-tracks. Then times changed, and we started putting in tape decks with trunk mount…

hey guys i have 2 hifonics xxv colossus amps an i have been told, i could link them with this MLX-100? if so how would i go about doing that? my amps dont have a master/slave switch.

i am wondering the proper way to ground an amp. ive tried 3 different spots on the body sanded the paint off and i dont think im getting a good ground. when my rca cables are pluged in i get a nasty sound and when i unplug them it goes away. i just tried a brand new set of rcas today and it did nothing to help. do i need to run a ground all the way back to the battery?

When building a sub box and putting pieces together how long do you clamp each pieces with glue until you pre drill and then put screws in and move onto next side?

could one 270 amp alt. charge up my starting battery and 2 kinetik hc3800's or would i need 2 alt?

when hooking up mulitiple amps would you run just 1 strand of remote wire to the first amp and then cut a second strand and connect both amps with the 2nd peice of remote wire? or would you run separate strands from the headunit to every amp?

When u caculate how many cubic feet your box is do you count the port area?

i have 2 kinetik 1800's and im going to put them in the back of my trunk in parallel. im getting rid of my stock battery. this is how i would wire it: i have 2 awg wire to connect the alternator to the battery. the wire will go from the alternator to battery A's positive terminal. Battery A's positive terminal will be connected to battery B's positive terminal. the stock terminal (from stock battery) will be connected to a wire that will be run to the trunk go to battery B's positive terminal. the stock terminal has 2 wires connected to it, one goes to the fuse box and the other goes behind the engine and i cant see where it goes to. my guess is that it goes to the starte…

If you have two 12in mtx subs at 600rms, and you have one 12in fi bl sub thats 1500rms. would the FI be louder? The fi sub is in a ported enclosure built to the specs and the two 12's is in a sealed prefab box???

My question is that I know line driver boost up RCA voltage but how does this help? I have a cheap pioneer HU and have to turn it out to volume 60/62 to get atleast 2 volts, And that is with like the loud and SLA option, my question is the line driver necessary in my appplication? And if i get some kind of bass processor with a line driver I well not have to get another line driver. Is there a way in me trying to make a line driver? Thanks for the help......

How would I go about creating more AC AMPS to go into the sub. I feel this would lower my box rise, true or false? I'm getting high AC Voltage readouts but I feel the AMPS are lacking thus creating a high ohm load. More DC amps going into the Sundown 3000? That's the only thing I can think of. This is a rundown of what I have installed '09 Toyota Yaris Pioneer avh 3100 2 din DVD (4 volt out) Pioneer 3 way 5 1/4's & 6x9's Pioneer 600 x 4 (4 channel amp) AA SMD 15" Sub Sundown saz 3000d DC Power 150/320 amp alt 1 Kinetik HC 1200 (up front) 1 Kinetik Hc 2400 (2.5 ft from the amp) Big 3 w/ extra grounds all in Fosgate 1/0 1 run pos.

What tools and methods do I need to calculate my imp rise. 1 15" AA SMD, Sundown saz 3000d. 4^3 @ 31hz, 30^2 port area (I know way to small, just testing an aeroport). Sub wired to .75 ohm Just got a clamp meter today and messing around I did 18.4 amps & 79.8 volts @ 37hz. I want to know what the impedance is doing but not exactly sure how to check for that Thanks
