Common Car Stereo Problems, Symptoms and Solutions: Aftermarket Stereos

Wall outlets provide volt AC power, but amplifiers require volt DC power. You’ll have to do a little extra wiring, but the problem is not insurmountable. Look up the input power specifications for your amplifier, using the manual or the manufacturer’s website. Find the specification for current draw in amperes. Purchase an AC to DC power inverter. Make sure the inverter can produce a volt DC output at the specified amperage rating. Cut a length of gauge red wire, a length of gauge black wire and a length of gauge wire, each long enough to reach from the amplifier to the inverter. Loosen the REM terminal of the amplifier with a screwdriver.

Cars use thicker cable due to the high amount of current being drawn from the battery lower voltage appliances tend to draw more current then higher voltage ones, it also helps reduce voltdrop. Someone has said that CCA is what you want to look for on a car battery this is incorrect as Cold Cranking Amps are for when the car is cold and you try to start the engine its designed for a very short duration while keeping a voltage of 12V, the actual battery usage you need to look at is measure in Ah these are usually much smaller then the CCA and are the rating you can safety continuously draw from a car battery.

Note for the writer its a great article but i wouldn’t recommend soldering then crimping, solder is very soft and will become loose after a while your better off crimping stright on the copper. I have recently hooked up my Amplifier to a PCU. But I only used one black and one yellow wire of the PCU to power it. You said to connect all the yellow wires to each other and all the black wires to each other, and to use them that way.

There are 3 types of fast attack submarines in the U.S. Navy. The oldest and most familiar, made famous by Tom Clancy in The Hunt for Red October, is the Los Angeles () class, which still makes up the bulk of our fast attack fleet.

Amplifiers are commonly added to car audio systems to provide extra power for speakers and subwoofers. Remote wires are included in amplifier wiring kits or can be purchased individually. Installing a remote wire is a simple task that should take less than 30 minutes. Strip off half an inch of the rubber sheath from one end of the remote wire using the wire strippers.

Attach this end to the remote wire terminal on your amplifier. Most amplifiers have a screw that holds the wire in place.

Common Amp Problems (and How to Fix Them!)

Silver Steel The only thing the head unit lets you do is adjust the bass, midrange and treble overall. It lets you use the fader and the balance and that is it. As to adjusting the sub so you get the low lows sounding good to your preference, sorry. The bass controls all of the speakers. It is for that reason I am looking into installing another subwoofer with an amp that I can set to take care of the lows like in my home theater system.

Jack I pulled these out after 10yrs in the basement, I built them in college and I’m 33 now so I am a little rusty on the details. Originally I used a 1 piece box that was the height and with of the back of my couch. The volume was achieved with proper depth. I tuned that to 37Hz by tweaking CV’s “high power enclosure” recommendation”. It was great for movies but too deep for music and weighed lbs. I then used those same parameters to get the frequency curve to peak at 43Hz and that is how I got the current volume in the two separately enclosures.

Since I am no longer in college and not going for max dB when playing music, I have been playing with specific port tuning maintaining the box volume of 3. I was using a port calculator and a speaker box calculator separately when I switched to 43Hz so there is a variable that I didn’t know how to work out. When choosing the frequency curve, I would just change the dimensions by trial and error until I got the one I was looking for.

If you know of a more advanced calculator, I would be more than happy to try it. I am actually thinking of going with sealed enclosures. CV recommends 2 – 3 cubic feet mut I also need to run that through a calculator to see what I think I want. As I always do, I will use my existing enclosures to fill n and prototype the next ones. If you can’t tell, I enjoy tinkering with it.

Car subs are traditionally designed with the concept of filling a small amount of space, oppose to a home which is a much larger area to pressurize with bass OT but this is something that I occasionally see posted on these forums.

I’ve yet to see a real explanation on why. Lemonslush, I dont mean to call you out on this but if you have more insight on the topic I am interested. A bit of background I have 4 sealed 12″ subs, 3 of the 4 are DIY “car subs” and one is a paradigm sub I started with the Paradigm, then had an old beater car sub sitting around from about 20 years ago wired it in with a cheeseball HTIB plate amp and was immediately impressed with the better room response but not with the output.

The cheeseball setup got replaced with an Alpine type R and plate amp, in fairness the Type R models well. A few years later I added a couple of kenwood subs that were on a blowout sale and something of an impulse buy, they model poorly and I was second guessing them until I hooked them up and got things dialed in. With a bit of setup they sound as good as the Paradigm and alpine and have respectable output. There is no appreciable sound quality gap and any output differences are easily explained with price.

Share on Facebook A powered subwoofer contains a built-in amplifier to drive a bass speaker that can produce low-frequency audio. It is a key component in a home theater system. The subwoofer adds an extra dimension to the listening experience by producing bass that can be felt as well as heard.

Dec 19,  · You can do what my buddy did a few years back. He made a cupholder out of wood that goes on the lump on the floor in front of the bench seat. It works REALLY well.

January 24, We are always preaching the more subs the better in a home theater system particularly two to four for a variety of reasons such as; smoother bass response across a wider listening area and increased dynamic range. So now that you’ve decided to purchase two or four subs, its time to show you how to connect them up properly to ensure you achieve the maximum benefits of a multi sub system. This article has been recently updated to incorporate two YouTube video discussions – 1.

How to Connect Multi-Sub. Why Have Multiple Subwoofers? Before reading this article, the reader is advised to check out our recently added YouTube video discussion on this subject matter to understand the benefits of using multiple subwoofers in a home theater environment.

Speaker Connections for proper impedance match A note about amplifiers: You should always use the recommended load for your amplifier. However, if you must use a load other than the recommended load, here is a short guide. Most solid-state amplifiers would rather look at an open circuit no speaker at all than a load.

Jan 27,  · Sometime next summer, I’m looking to knock down my current leaky single-car garage and put up my Garage Mahal — a 2 (or maybe a tight 3) car .

Next Audiophiles know that a stereo is not complete until you’ve added a subwoofer to your system. The subwoofer is a speaker specifically designed to give precise sound to low frequency audio, such as the bass [source: Whether in your car or your home theatre, a subwoofer is a must for a true and complete audio experience. Read the steps listed below and learn about how to connect a subwoofer to an amplifier. Turn the amplifier and the subwoofer so the backs are facing you.

Every car audio installer, indeed, every automotive professional, will always recommend this first step: You want to do this in order to avoid any possibility of a short circuit. Remember that on many late-model vehicles, you will need a “radio code” in order to reactivate the radio. Amplifier Location Presuming that your car or truck has an existing stereo sound system and that you are interested in installing one or two amplifiers as an upgrade, the next step will be to decide the mounting location for the amp.

Mount an amplifier less than three feet from the car’s radio or bolt it directly to the vehicle’s metal chassis, and you’ll hear a lot of annoying static, buzzing, and humming over your music. While mounting an amplifier in trunk or hatchback areas is usually a good idea, securing it in an upside-down position as seen here is not. To make sure heat can rise out of the amp and escape, make sure ventilated slats are facing up or to the side — not down.

Amplifiers have slotted cooling fins on their surface to release internal heat that builds up.
