very cheap sound system

alright, i had 2 audiobahn flame q 12s in a ported box pushed by two legacy predator supposedly 600rms, the audiobahns blew and im looking to buy two new subs, a dealer near here said that he could get me 2 12 hifonics for $250, would this be a good deal, when i raise 500 dollars more im going to buy a new amp anyway, im going through withdrawals of bass and i really need to get subs back in my car, if this is not a good deal, could you reccomend one that that i could ask the dealer about so he would be able to get me a warranty. i dont want to buy anything off the internet

what usually happens if you dont upgrade your alternator and your lights dim severely,

what is the worst that can happen

so you want to use subs that are 175 a piece with an amp that is $500?Maybe you should save and spend a moderate amount on both with your $750.Hifonics subs are decent, but it depends on which model.  Can you get that info for us to review?

The voltage fluctuations can actually damage the very expensive electronics that run your vehicle, if your constantly dropping the voltage below 12 volts your bound to fry something sooner or later. If your alternator can't keep up with your power consumption and you need to listen to the stereo loud, then you need to get a HO alternator to satisfy your electronics and your stereo will be much louder and clearer too if you feed it a constant 14* volts.

my dealer said the subs were good for the money and the amp was good either way, he sells mostly memphis.

he said he could get me each sub for 125 a peice and the amp for 500

good deal?

will it blow?

how loud will it be and whats the quality gonna be like?

any suggestions are very very welcome, within the same price for the subs, because i cant afford the amp yet anyway, if theres a better cheaper amp please mention it. if theres better same priced subs definately mention it, ill ask him if he can order it for me.
