see my whole problem is that i have a head unit that doesn't have sub output, it only has 1 pair of preout front and rear on the back of the cd player so i getting more that just bass to my subs...so i guess the best thing would be to get a xover right? So when i buy a xover do i just run rcas from my head unit to the crossover then from the crossover to my amp? and a power ground and remote and thats it...or is there more to it?
most amps made (95% ?) in the last 10 yrs have crossovers built in.
You said "one pair of front and rear", so 2 sets? That should work fine. You run your front amp with the front rca's and your sub with the rear.
You can spend the money on a crossover if you want one, but you don't NEED it at all.
It can be done with just one pair of pre outs and some y cables. It's the least desirable just because you can't fade, but in the big picture that has no direct effect on the performance of the system.
4 pre outs is optimal on a crossover. sub, mid bass, mid woofer, tweeter.. for a very dynamic system.
But yes, most good quality decks will have your front, rear, and sub. (Sub can also be labeled as non-fading.. meaning that when you adjust balance from front to back, left to right, etc, it dosnt effect the subs.) But also, a lot of decks have a crossover always active on your sub-out line, too..so you cant use this line as just another set of RCA outs, as it has a crossover perma-active. (My deck, a JVC SHX900, has options to set the LPF to 80, 60, and 50, on the sub-output RCA's... and cannot be defeated).
it doesn't freaking tell me anything... i did read it carefully, so i guess no one none of you really have enough knowledge to tell someone what to do when they don't have a sub-out on there head unit...all optidriven says is that they are good for a dynamic system and that what u can and cant do and what his has..it doesnt tell me what i need to do about not havning it and thats all i need toknow
ohhh isee what your saying know, im pretty sure you bought a cheaper headunit the cheaper head units when you turn up the bass all the speakers sound ugly and disorted with too much bass right. And your subs sound like if theres treble coming out of them right?i dont know wht to tell you i think theres no fix for your problem other than get a new headunit.
