what brand of Amplifer schould I buy for my car stereo that is not too expensive(200)?

Answer 1

Look for this when buying an amp... http://www.crutchfield.com/S-wn5MvZJYp33/popups/cacomp.html

CEA-2006 Compliant

On May 28, 2003, the Consumer Electronics Association published standard CEA-2006, "Testing & Measurement Methods for Mobile Audio Amplifiers." This "voluntary" standard advocates a uniform method for determining an amplifier's RMS power and signal-to-noise ratio. Using 14.4 volts, RMS watts are measured into a 4-ohm impedance load at 1 percent Total Harmonic Distortion (THD) plus noise, at a frequency range (for general purpose amplifiers) of 20 Hz to 20,000 Hz. Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. This applies to both external amplifiers and the amplifiers within in-dash receivers

If an amp doesn't have this rating, it may not produce the watts it says it does.

Your system won't mean squat without a well designed box to put your subs in. Some manufacturers have recommendations as to dimensions of various types of boxes. It is best to find someone who builds boxes if you go with something other than a sealed box.

You should always match up RMS (Root Mean Square) watts of Subs and amp per channel as well as impedance's(resistances). When a sub has rating of 600 Watts MAX it really has an RMS rating of about 200 Watts RMS. RMS is the nominal wattage your most likely going to get out of it. Remember, a 200 Watts RMS amplifier has more power output than a 200 Watt MAX.


If your amp is rated at 4Ω don't subject it to 2Ω, it will fry.

Here is the formula for subs in parallel:

Z = 1 / (1/sub1 + 1/sub2 + 1/sub3 + ....)

For series, just add them up (sub1 + sub2 + ...).

You can mix and match these equations to get the right impedance required by your amp.

Example 1: Amp is 2 channel and rated at 4Ω when bridged, 4 subs @ 4Ω each. If I connect two in parallel and the other two in parallel and connect the two pairs in series, I would have a total impedance(resistance) of 4Ω. So to the amp, it's just one sub when bridged.

Example 2: Amp is rated at 1Ω mono, 2 subs @ 4Ω each dual voice coil. If I connect two voice coils in parallel and the other two voice coils in series and connect the two subs in parallel, I would have a total impedance of 1.6Ω. Which would be perfect for a 1Ω stable mono amp.

You should use a capacitor as well.

Recommend for every 500 watts MAX you use a .5 Farad cap
Example: 1000 watts MAX - 1 Farad cap

You will also need what's called a "line level converter" if your stock head unit doesn't have RCA outputs or your amp doesn't have high-level inputs.

If you like I can send you some plans for reference. My plans are for a 4-th order band-pass bass box (A.K.A. bass-reflex) that holds two 12's.

Also included are java calculators you can use to figure parallel and series values given Ω values, tips on box building and types, calculating port diameter and length(if used), calculating box dimensions for types of boxes (sealed, wedge, cylindrical, etc.), materials needed and even how to make a jig for cutting perfect holes for your subs.

Just e-mail me [e-mail]

My system

Blaupunkt TSw1200 subs with a Sony Xplōd XM2200GTX.
My amp is 1200 watts (200 Watts RMS X 2), subs are 600 watts (200 Watts RMS) each, cap is 1.5 Farad w/digital readout

SPL is about 112 db each sub

Total cost(so far) = $410

To the other people ranting about my answers.

Some people have made pot-shots at my post because my answers are "one size fits all" as one person put it. I have gotten at least 25 best answers (and growing) with e-mails requesting more information from this same post since I posted it.

I'm just trying to be as informative as I can be. There might be something the poster didn't think of, forgot about or doesn't know.

These peolpe may not like my style of response, but then, no one asked them.

Answer 2

for abot 250 you should be able to get a 1100 to 1500 watt hifonics mono block on ebay they are great amps i have a 2000 watt rms amp and it just plays with my subs which are 2 12" audiobahn flame q's1100 watts rms like its nothing but that ones 350 well worth it though

Answer 3

it really depends on what features you're wanting, such as a built in crossover, power output you're looking for, number of output channels, etc. Go to www.crutchfield.com and look at their amp offerings. They also have an outlet section and a scratch and ding section that offers reduced prices on audio items.

Answer 4

try to get your hands on a bazooka, the have a good kick but still have a decent price. if not try the Sony explode.you can find a bazooka amp at circuit city.

Answer 5

go to Walmart or if you have an Auto Zone they have some decent ones for a good price

Answer 6

try ebay. and it depends on how much power you want. i wouldnt go cheapo, cause going cheap on amps scares me. try some kicker, kenwood, boston, pioneer.

Answer 7

go to wal-mart if you want cheap exsplain to them what you got and they will find you some thing that will work for your system

Answer 8

Bose!!
