choosing 4 channel amp- need help

[trevtrev]

i just bought 4 12" sony xplod 1500 watt speakers. i now need to figure what type of amp i need to get maximum power from the speakers. i know very little about amps, and out of all of the amps i have looked at- the most wattage i have seen in 4x300 rms at 4 ohms, is this enough power. also, why are the off brands sooo much cheaper for higher power amps? do they not work properly? is a 4 channel amp the only solution? if anyone has any suggestions on what type/brand/watt/etc... amp i need i would really appreciate it. also, is audiobahn a repectable brand? thank you

It depends on what you are referring to as on 'off-brand.' Typically brands such as Pyle, Legacy, Pyramid and the like aren't a good investment even at their bargain-basement prices. On the other hand, units built by Profile, US acoustics, a few of the offerings by Lanzar, and so on while possibly not giving you rated output tend to be reliable units for the cost conscious.

is a 4 channel amp the only solution?

Not at all. You can also go with a 2 channel unit and run two subs off of each channel and you can also get a single channel monoblock unit to drive all four subs. Which kind of amp you need will depend on what specific Voice Coil/Ohm rating configuration your four subs are.

Knowing exactly which model of subs you've gotten for yourself so that we might know how the coils are configured would be a great help before anyone could offer you a really educated suggestion. I've never used any Audiobahn gear myself but it doesn't seem to be particularly popular to the regular posters on this forum.

I suggest a mono amp stable at 1ohm...........look at the 1st wiring diagram!

get somthing like a hifonics 750d, or bx1000d. will suit your needs.

to be quite honest tho - those speakers are in the 'bargain bin' along with those amps you were talking about.

i would never ever buy one of those, unless i was going to plug it into a wall socket to see some flames.
