Car audio question

[psunitro]

Once i get the money from my Sportmaxx i sold for $300, I'm gona get some 250 watt tweeters, by-pass the factory amp, and replace all the factory speakers with something with 150-300 watts each, whatever fits

PLEASE dont just go by what the speakers are rated for. Having a nice set of speakers does not mean having the ones rated the highest. They are just "peak" numbers. Look at what you plan on powering them with. If its just the stock HU,go with a cheap set of coaxils. If you plan to put a moderate size amp in buy yourself a matched component set. This will have the x-overs you will need for the tweeters/mids. If you dont have a x-over for the subs,I would say get one when you have the extra $$$.

I dont do the "boom" systems anymore. Last one in my car was a ADS 6 ch. amp getting signal from a pre amp only Eclipse 5303r running a Polk GNX 10 and a set of 6x9's. Nice simple system. Clear as a bell,never got around to putting in the front speakers....lol.

Here is what you do. Make sure your ground from the battery is good. If you have to take the wires off and clean where they mount to the chassis. Next take the ground from the amp and clean that one up as well, and make sure the amp is not grounded to an existing screw. If you have to drill a new one be carefull. Sand the area surrounding the connection, and then put some silicone (to seal it) where there is bare metal both sides (inside and out)

If it is still buzzing you'll prob have to reroute wires. You don't want power wire to be next to wires that carry any kind of signal. ie rca wires and speaker wires. My rule of thumb is to pass them on opposite sides of the car.

Try the first step then go from there. Hope it helps.

i had the same problem and a commom mistake is running the power wires right next to the rca jacks as "vbgagnon" said power on one side rca's ,etc. on the other also a good ground as others have said,i've also had a few bad eq's that have caused problems with whining noises...good luck!!!

well hb111 ur a little late, lol, i got the problem fixed last saturday but thanks ne ways.

psunitro- If u read the other posts u would see i dont have the stock head unit and i already got a high powered amp, so more watt more thump

later

More wattage doesn't exactly mean more thump. Watts very from different brands. "Thump" might rate a sub at 1000Watts but them are going to be wayyyyyy worse than 1000watts from Kicker or JL. You seriously get what you pay for in the audio game. Stay away from Cheap speakers who try to sucker kids in by giving out big wattage numbers. When your looking at speakers, look at the RMS cuz thats what your actaully getting and running it at. Also stay away from cheap amps. A amp is going to be your key in a good system. You can have kick ass subs but with a cheasy amp there gonna sound like ass. And if ya have a great amp, your gonna get the best sound out of the subs, even if there crappy ones. Stick with name brands... Kicker, Rockford, Sony (I'm not a fan of), kenwood, etc... Also dont EVER buy subs that come in a box and have the tweaters built in. They usually sell these setups at walmart, Auto Zones and other cheapy places like that. They are a TOTAL waste of money. Anway if ya ever need any pointers on installs and such, feel free to pm me. I competed in Usac and DbDrags for 7 years and held the Loudest DB's in Mn for 2 years..

 

[kwong2001]

lol, I hate Sony's. I bought a full set of xplods and it ended up crapping out on me. The subs started to sound like poop, then the amp started overheating and cutting out. I got them claimed under the insurance I bought, paid a few buck more and got a rockford fosgate amp and phoenix gold subs. Then eventually I bought a Rockford Fosgate component set and Pioneer headunit.

Too bad i'm starting to get really sick of my system. I've listened to it for so long that it's really starting to sound like poop. It's way better than stock, but the little things really annoy me. And the headunit can't compensate. I wanna goto JL Audio but i'm broke

BTW, what was your highest DB's you ever hit? Did you ever goto the nats?

 

[shadey26 ntc3]

He man let me help you out. all the advice you have been receiving is true. But one thing remains. What kind of cables are you using? What kind of power wire are you using? They play a major role. As far as your noise its called a ground loop. Are your amps mounted being mount to a amp board? or are they being bolted down diretly to the car? Most amps will give off noises if there shells are grounded out. There are so many culprits. BAd rca coming from the head unit, cheap cables. power cables next to rca, bad grounds, faultly amps or about to go out. voltage drops. ect. even cheap power wires can to be blamed not alone a alttenator going bad. If you can send me a diragram on how they wired your car i can help you! Its kind of hard. I am a mecp certified. and have been doing this for years. As far as a cap it will make your bass hit harder. It does this by storing a electric charge and discharging it quickly. It helps your amps buy not going all the way to the main battery to get its fixs or fuel. Also did they use the proper power wire to the back of your car. You should be using four gauge wire to the back. I also need to know what ohms are your speakers, Just because you have 1200 watts don't mean your using it. exp- if ur amps are putting out 1200 watts at 4 ohms and you have two four ohms speakers in parellel thats a two ohm load bridge mono thats a 1 ohm load at your amp. most amp can't handle that , most of your power would be transferd to heat. If they were wired in series that would be 8 ohm bridge mono the amp would see four ohms. get it ? Can you do this for me . check to see if the power wire and the ground are the same size. most people dont use the same size and this play a major factor. I know I might have confused you and I am sorry. If you need help call me at my shop. Srry for the content I can explaijn it better on the phone computer sucks. o yea. I will give anyone thats a member on this site 10% to 20% off any car stereo items that they need. srry I can't match internet sites as they might be refurbish or not a dealer item peace
Please do not post phone numbers. PM the member that Info directly.jon2 RCNT Staff

I would consider it but having a family, I want to be able to hear them. A decent deck and speakers are all I need in my car...in my wifes car is a differnt issue. I am getting a TFT LCD's installed on the ceiling. Its a 12 " monitor and I am using the PS2 Slim version as the dvd and game console of choice.

Jon waaaaaait dont do it! I might be able to get you a 15 for the price you are going to pay for your set up.. Did I say my company is mobile? I will come to you , ur not that far. and I would love to return the favore for helping me out with my car and the good deal on the bumper! Holla at ur boy!

 

[Maxx Trooper]

4u2nv- yea ur right, thats what everyone tells me, My sub i got from PepBoys for $70, 2 10" and built in tweeters, rated at 600 Watts. I just wanted to me somethin going, start small and build up. I just picked up some Pioneer 6 1/2" for the front and 6X8" for the rear, make watt for each is like 250 watts. they should go nicely with my Pioneer head unit.

kwong2001- from what everyone tells me Sony sucks, the place where i got my system installed told me that 4 out of the 5 warehouses closed down. so go figure.

shadey26 ntc23- I'm using a Legacy 1000 Watt wiring kit, it had all the wires for running the amp and sub. the amp is mounted to the back of the sub box. The guys used a inline filter to filter out the static noise. O yea dude u completely lost me once u started to talk about running the wires. There is a red wire, blue wire and black wire. the black wire is grounded, the blue wire goes to the head unit and the red goes to the battery. They are all the same size, so I'm firguring the same gauge. Its a 4 channel amp and the guy used splitter i think for something, not sure what. i can't take a pic man if that helps any.

thanks,

psunitro- If u read the other posts u would see i dont have the stock head unit and i already got a high powered amp, so more watt more thump

i got a new head unit sony cdx-m630 for a good deal but in may I'm gana up grade to a pioneer 6600 or 7600

more watts dont mean more thump


nitro13,

If you could supply use with a crude wiring diagram, the brands and sizez of cables used, and the equiptment from the deck to the crossovers to the speakers and amp I bet we can find a solution.

I have been a do it yourself low budget stereo installer for years. I have installed from Pyramid in a friends car, the the Fosgate 12's and Alpine head in my truck.

One of the first things you can do is disconnect the RCA's from the deck at the deck. If the noise still apears it is not from the deck. Then disconnect the RCA's at the amp, if the noise is still there it is in the amp and it's wiring. If the noise stops when disconnected from the deck side it is the deck. If the noise stops when you disconnect the rcas from the amp, you know it is the RCAs


Let's start with all the possible causes, you cross out the ones you know are not an issue and we'll deal with what is left.

Noise can come from
Improper grounds, and weak connections
Shared grounds (amp and deck grounded to same spot.)
Improper size for power wire (puts load on amp causes heat thus noise from failing chips)
Bad ground from Chassis to engine block.
Failing or cheap deck CD motor
Failing, or overheated Amplifier
A failing alternator
A failing blower motor (heater / ac)
RCA wires routed with the power ground and remote wire.
Unshielded neon transformers

RCA wires operate on very low voltage, they move the sound from the deck to the amp. A higher voltage wire next to it can actually bleed it's power over to the RCA's and that power is static the staic is amplified by your power amp.

Often the ground from the battery to the engine block is good and secure. But to ground the chassis you need a strap from the engine block to the sheet metal of the car (usually firewall) if this becomes weak or corroded the body of the car you are grounding to is not itself properly grounded.

IF none of these help you can try wrappping the amp and the deck in tin foil to see if it helps sheild the interference. You need to find out the source of the noise to eliminate it. Noise filters will mask the propblem, and not solve it. 50% of the time they do nothing for the noise.

Please let me know the source. I havebeen following this thread and I am very interested in it's outcome.

J/K.......The pics WERE there, but I was looking at the thong. Sorry, I'm easily distracted.

 

[kwong2001]

Yeah, who's the chick with the thong? I was looking at her WAY more than the system.

thanks for the help but the problem was solved last saturday. i had a in-filter installed and the static is gone, and its crystal clear.

Rolex- i thought thats wut u ment, u were being sarcastic.

kwong2001- The chick is actually my x g/f's older sister-in-law. there both a couple of sluts. lol. I forget what kinda car that is in the background... but who cares. lol

If the length of your ground wire is too long than this will cuzz engine noise coming through your speakers. Get a ground kit for the entire car for like $30 on Ebay and install it. It is a 5 point ground system. You system will bump with no hum and your car will actually be faster...........no lie!

hahah guess I am to late to the party!

yea i have heard about the ground kits, they are suppose to increase Hp which is pretty cool. i might pick one up this summer. yea u are a little late. lol

Yup on that Ground wiring kit to help out the performance of the car. No need to do that right away. I am doing it to my Civic HB when my funds come.

lol nice, never read that before.

i got a question about the sound proofing stuff that u can put under the carpet and in the door panels, does that stuff really work to keep the sound in ur car and the outside noise out of ur car? cuz the stuff is like $100.
