What is a good CHEAP amp to power two mtx audio 10" 8500 subs?

Question

Any suggestions?

Answer 1

that model of sub comes in DVC or SVC (dual or single voice coils) so that makes a huge difference http://www.mtx.com/caraudio/products/sub...

this link will show you how to wire them up- just put in the number of subs and the subs setup (DVC or SVC and the impedance) and it will show you all of your wiring options and what the final impedance at the amp will be also http://www.the12volt.com/caraudio/woofer...

when you do find an amp make sure its CEA-compliant and has about 1000watts RMS @ the correct impedance

when it comes to car audio nine times out of ten you get what you pay for- and you need to look for CEA-compliant brands which means that the amps have been tested and produce or exceed the advertised RMS wattage with minimum distortion

(distortion is the main cause of speaker damage over time)

here are the top CEA-compliant brands

Alpine

Bazooka

Blaupunkt

Clarion

Eclipse

Infinity

JBL

JL Audio

JVC

Kenwood

Kicker

MTX

Pioneer

Polk Audio

PPI

Rockford Fosgate

Sony

if you dont go with a CEA-compliant brand you dont know the "real" RMS wattage so its impossible to properly match your equipment, heres what can happen

if you send too much power to your sub, you risk damaging it. The cone of the speaker and the mechanical parts that make it move may break under the stress. Surprisingly, too little power can also damage your subwoofer — in fact, it's actually more common than damage caused by overpowering.

When the volume is turned up and the amp doesn't have enough power, the signal becomes distorted, or "clipped." This distorted signal can cause parts of the speaker to overheat, warp and melt. Not good!

You don't have to match speaker and amp wattages exactly. An amp with a higher output than the speaker's rating won't necessarily damage the speaker — just turn the amp down a bit if you hear distortion from the sub and don't run the speaker at extremely loud volumes for lengthy periods. Likewise, you'll be OK with a lower powered amp if you keep the volume down and don't feed a distorted signal to the sub

with a non CEA-compliant amp you would be lucky to get half of the advertised RMS wattage and it would more than likely be distorted from a lack of wattage

you will send the amp into clipping

Clipping

Clipping occurs when an amplifier is asked to deliver more current to a speaker than the amp is capable of doing. When an amplifier clips, it literally cuts off the tops and bottoms of the musical waveforms that it's trying to reproduce, thus the term. This introduces a huge amount of distortion into the output signal. Clipping can be heard as a crunching sound on musical peaks.

that causes distorted sound which will damage your subs
