Answer 1

take your time and save up a little

the cheap stuff like that does not last and will just cause you headaches down the road and more money

its non CEA-compliant

you would be lucky if the amp puts out half of the advertised RMS wattage and it would more than likely be distorted (the main cause of speaker damage) and the subs would be toast if you really sent their rated RMS wattage to them

with CEA-compliant brands the amps have been tested and produce or exceed the advertised RMS wattage with minimum distortion and the subs can handle their rated RMS wattage also

here are the CEA-compialnt brands

Alpine (highly recommend)

Bazooka (don't like their subs)

Blaupunkt (don't like their subs)

Clarion

Eclipse

Infinity (highly recommend)

JBL

JL Audio (very good but over priced)

JVC

Kenwood (don't like their subs)

Kicker (the best in my opinion)

Memphis

MTX (highly recommend)

Orion

Pioneer

Polk Audio (highly recommend)

PPI

Rockford Fosgate (highly recommend)

Sony (don't like their subs)

if its not CEA-compliant you dont know the REAL RMS wattage and without that info its impossible to correctly 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.

heres what i would recommend for a GOOD starter system

(about $400) these subs and box http://www.sonicelectronix.com/item_3867... with this amp http://www.sonicelectronix.com/item_8651... or this amp http://www.sonicelectronix.com/item_5027...

hope this helps, good luck

Answer 2

i wouldn't get either because bot are low rated and made very cheap look for Rockford or alpine you spend more but you get more plus that roadmaster is c**p that you get off the bottom shelf at walmart  

Answer 3

The subs aren't really subs. They say 6 1/2" which are door speakers. I suppose the 6.5" in a box will make a thump, but essentially they are door speakers without the highs. Its life a component set in a box rather than your door. I may be wrong. I always understood that 8" was for mid bass, that leaves everything smaller for mids and highs and everything bigger for subsonic noise.

Answer 4

Eeewww! You don't want roadmaster anything if you want any sort of good sound. Especially since those subs can only handle 50 watts RMS each.

Don't waste yourt money.
