Amp Wattage

hey everyone, just wondering about the wattage of my sub amp, i plan on buying 2 Precision power subs that are 300 watts RMS and dual 2 ohm voice coils, the way im goin to wire them up equals to 1 ohm per channel, now the amp is a sound stream one and its rated at 1000 watts RMS at 1 ohm, will this over power my subs or do they only use what they can handle

The amp has how many channels? Some amps rate the total output of all the channels added together in my experience, while others actually rate the max amount a single channel will output.

As Above - it will depend on what rating is it - Bridged or per channel etc. Is it a mon amp.

but in general and I'm a little rusty on mobile/car sound gear - getting back into it a little.

Everyone has a different opinion on if you should have a more powerfull amp or better handling speakers. it's been going on for ages. I've come to my own view, of quality over POWER. Then again I put 2gauge cable in a car and 2 farrad capacitors for two 15inch subs.
Everytime I went for more power then any of the speakers could handle.

Yet I've had the oportunity to make some very nice home theatre setups and even using low powered Valve amps mades some very very crystal clear sound.

I think it's more then enough unless you really want to drive your subs totaly hard.

The other item to think about is. When you AMps at such low OHM draws is the current DRAW. Question do you really want to push you your Electrical sytstem that hard. On BG the stock alternator IMO and history is a Mitsu****TY. It will put it under alot more strain and you will problery kill it in a few months. So be prepeared to upgrade = loss of engine power - small engine large alternator will suck more HP to turn it over.

But again with out known what type of Amp it is ?

I always found it better to fit smaller seperate amps instead for each sub. even two mono 500Watts and a 800w 4 channel was better then a 5 channel I once fitted. Much clearer.

Go 4 ohm for sure. Way less demanding on your electrical system for starters.

FYI those subs will wire to .05, 2 or 8ohm. Two dual 2's wired in series will create 4ohm each, then wired together in parallel will become 2ohm
