So my plan at the moment is to buy new subs that are within my budget that leave me a little room to grow. Amp's seem pretty cheap these days and I can upgrade that later since my current one is working just fine. I don't understand how you say I won't notice a difference by adding 200w, I noticed a significant difference when I went from a 300w amp to my current amp. I'm not talking trash, I just don't get it.
Are the subs you are wanting going to be in the power range you want to be at later?
you have to know what you are looking for in a sub. say you want to run your amp at 2 or 1 ohm, are those new subs going to be rated for more power than you have now or do you want them to be rated for more?
Any amp running at lower ohms wastes a lot of current, and the amps do not perform as efficient as they normally would. it draws more current than it outputs. 200 watts wouldn't matter because your subs would not receive a full 100w x2, your amp may draw 200w more. but your speaker would receive much less.
If you bought new dvc subs with a higher power rating they would really see no benefit from less than 100w extra each.
Sub choice is on your electrical system headroom, available amp power or soon to be, box size and type, price, sound quality and level.
so do you plan on upgrading your amp or keeping it?
Will running new subs at a low ohm pull too much power?
Can you make/buy make a solid custom box?
do you want low reverberating bass, or do you want solid hard bass?
how loud do you want it, artificially louder than your door speakers. or, a healthy amount of bass that blends well with your door speakers?
