as far as spec's which sub will hit da hardest loudest clearest one sub is rated at 500rms hz20-250 ohms4 spl88 and max output 1000watts while the otha sub is rated at 1200rms hz25-1 ohms4 spl87 and max output 2800max i dont wont 2 put the brand becuse of two reason one being people will knock it b4 they try it and two being lets see who really knows there shit bout car audio now with that said what type of amp would best suit either sub

Well without more information or actually hearing both in person no one could say which would be louder.

Can't answer question 2 either without knowing whether the subs how many voice coils it has? Is it single or double?

But yeh i do agree with you about the people knocking shit. Ppl on the net tend to knock everything thats mainstream and say go with Fi,Aq and etc. because it's better, which in a lot of cases aint true.

What kinda power you got? what are you trying to do? sub sizes?




We may say ditch the mainstream subs is because most mainstream subs are what some may call "throw aways", once you blow them, you gotta throw them away, most underground companies (fi, aq, dc) can all be rebuilt, use better quality parts, customer service is alot better since you speak with the person who usually builds them and actually knows what their talking about instead of referring to the manuals lol and being price to performance ratio kills mainstream.

Is mainstream bad? no and could suit you better than underground companies.

But for those who got a good idea on car audio, mainstream is usually not the first choice
