channels question

[Zach85 10+ year member]

I'm thinking about buying a sub soon and getting an amp to go withi it. It is DVC, so I can do 4ohm or 2ohm.

I found an amp that I saw something I was wondering about:

250W RMS x 2 Channels @ 2 Ohm Stereo

does this mean 250 rms PER channel, so I could just hook my sub up to the one channel in a parallel connection, or how would that work if I only connected my sub up to just the one channel? Here are the specs:

Features:

Model: MA Audio 300XE

High Performance 2 Channel Bridgeable Car Stereo Amplifier

500W (Max) x 1 Channel @ 4 Ohm Stereo (Bridged)

250W RMS x 2 Channels @ 2 Ohm Stereo

125W RMS x 2 Channels @ 4 Ohm Stereo

Full MOSFET Circuitry

2 Ohm Stereo Stable

3-Way Protection Circuitry (Short/Overload/Thermal)

Selectable LPF/FULL/HPF Crossover

Adjustable Gain Control

Power and Protection LED Indicators

Low Level RCA Input/Output

High Level Inputs

Specifications:

Variable Low Pass Crossover Frequency: 50Hz-250Hz

Variable Bass Boost: 0-18dB @ 45Hz

Subsonic Filter: 20Hz-50Hz

THD:

Channel Separation: 50dB

Dimensions (L x W x H): 9" x 10" x 2"

Thanks.

I am new to Motorised Satellite systems and have been searching in vain to locate the satellite and Frequency of the following channels I have seached high and low but have had no success.

Uh, what does this have to do with my topic?

There is no DVC sub that can be wired to 2 ohm or 4 ohm. I'm going to guess you got dual 2 ohm subs. They can be wired to either 4 ohm or 1 ohm. If they are dual 4 ohm, they can be 8 ohm or 2 ohm. Figure out what each coil is on your sub and get back to us.

it is 4ohm DVC. I'm not worried anymore about this, I just saw last night during some extensive research that if you have DVC, parallel is much better than a series.

Well you're wrong. Parallel brings the impedence down. If your amp cannot handle that low of an impedence, you can cause damage to your amp and/or subs. Neither parallel or series is better than the other one all the time. One or the other is more appropriate for a given situation.
