Ok, i have an MTX 4122 amp (30x2 @ 4 ohms, 60x2 @ 2 ohms) laying around. Right now i have 2 15" phoenix gold titaniums in the back, and then crappy lightning audio 6x9 and 6.5 coaxals. Would it be worth it to run the amp, or should i just run them off the deck. Any suggestions would be great.

amping any speaker will make it sound better

Ok, so the next question is, what should i get? Should i get a good set of coaxials, or a cheaper pair of components? I'm looking for a little more front fill and a little less rear fill. I'll probably keep the lightning audio 6x9's for the rear fill. They sound decent as long as the aren't being pushed hard.

how do you like the titaniums?

well, they sound pretty nice so far, but i still have them waaaay underpowered. I've got 380 rms going to the pair. Sooner or later i'm gonna get either a JBL bp1200.1 or a Hifonics bx1500d to really power them. We'll see how they sound then.

nice. i have a 600.1 on my 2 10s and i love it. these subs move so much. did you have any problem with your tinsel wires being too long?

no, mine look fine. I can't wait until i can see the full excursion these guys have.

are yours in a sealed or ported box? Have you ever gotten it measured on a mic? I'd like to get a better idea of what i'm shooting for

sealed. 1.ocuft per sub. no i just got them installed and they have worked fine for a few weeks but 1 of my tinsel leads was too long and snapped off from the terminal. so i have to resolder it. im guessing i can hit somewhere in the 130's but who knows. those 15's should pound even with 1000watts. what box do you have them in? and whats the rms of t he 15"?

they are in 1.7 cubic feet after displacement sealed (recomended airspace is 1.75 for spl, 1.25 for musicality). The RMS rating is 550 each, so 1100 for the pair. I'm thinking JBL bp1200.1 for that.

the 1200.1 is plenty for that. my sub box recommendations are weird....55 for musical, and .3 for spl. this as per owners manual. makes no sense if u ask me. the #'s are before displacement. i mean .3 for spl? thats like no space

Yeah, they don't need a very big box but .3 is wayyyyy small. For the 15's the spl box is bigger than the musical, but apparently its reverse for the 10's. If you put them in a .3 cubic foot box it might be loud but there would be now low end freaquency extension.

thats why i have them in a big box. they go deep so easily.

i've thrown mine 10hz a couple of times and it is insane.
