  3. 18" subwoofer for under 400?

    ^yes its "any good" also i got my dc xls new for a bit less than 400 each...not sure on the pricing of the new m2s though.

    Honestly, you arent going to be disappointed with any of these speakers. Just read up a bit more, look around the forum and see what kind of results people are getting from their different setups and base your decision off of that rather than starting threads asking what to use.

    Good luck with your search!

  7. Good price for a 3500-4000 watts rms Mono

    I posted this for someone else before too but ill let you know as well as it is applicable.

    For comparison this is my electrical for similar power, sundown saz3500 at 1.4 ohms nominal

    1 220 amp HO alt, 1 xs 2700D, 1 xp3000 with two 1/0 runs from the alt to the front battery (2 grounds from the front battery to the frame) and the rear xp3000 is connected to the front with 1 positive and 1 negative ground.

    I charge at 14.4V and I stay low 14s high 13s while reving to 2000rpm on even the "worst music" (music that causes the most voltage drop) full tilt for whole songs.

    Before I added the 3000xp i felt safe running the system but I just had to be a bit more careful and watch voltage and turn it down when it started to get sketchy.

    For amp choices I would expect to spend at least $600. I know you can get a crescendo for that. Used sundown 3500 or audioque 3500 would be right around that price too

  9. PPI Black Ice amplifier line

    i believe the power class is their new top of the line followed by the black ice, both of which are supposed to be much better amps than they have been producing lately. I read a thread about it on CACO i think? They are trying to make a comeback supposedly

    honestly bro i'd just get what you like and upgrade your electrical if it doesnt put out what you want.

    lol thats the easy way out bro! I'm tryin to learn somethign new haha. But yeah i assumed it would come down to that. She wants to compete in idbl rookie trunk class for the time being which is limited to stock alt and one battery in stock location so electrical is what it is at this point, efficiency is the name of the game.

    Now to find a DD dealer and compare some prices i guess...

    gothcha its for competition. Do you HW then man! and go to events and see what the winners are running. I saw alot of american bass stuff and DD in the db drags and DC

    for sure, the hunt continues! had forgotten about ab actually

    doesnt dd rate their amps at lower than 14.4v? Im not sure on the exact number but i thought they rated at 12.5v??

    12 flat according to the website

    precisely what Kranny said. So sundown rates at 86% efficiency at 4 ohms but at 100Hz, skar is 85% at 4 ohms no frequency given. DD rates 87% with no load range or frequency so they are all around the same it would seem.

    Does anyone know of some tests anywhere comparing these numbers? The closest thing i can think of is Fecupe's 1500 watt challenge thread. There the DDs seem pretty beastly creating more power for voltage drop than the other but no sundown or skar were measured in that test.

    Thanks, do you have clamped numbers for output and what electrical the skar was on etc?

    I guess I am looking for more real world data/numbers.

    I am aware that all of the skar sundown dc aq dd amps etc exist, I am more looking for some technical reasoning behind the suggestion

    edit: lol don't worry Kranny it wasnt in the running

    I am doing an install for a friend and I am looking for an amp to do around 1500rms (could run at a higher ohm load than 1 to achieve better efficiency if it is worth it, she has not bought subs yet)

    It will be run on a stock 110 to 90amp alternator (still not sure which is in there yet) and as large of an xs d series that I can fit under the hood. So I am wondering if you guys know of any amplifiers that will do that power and are exceptionally efficient. I.e. will work well on this electrical with low current draw while still putting out rated.

    I know box will have a ton to do with efficiency as well but I am just talking about electrical here. Looking for suggestions, help me out if you can!

    *don't turn this into a verse thread if possible please

    not bad at all. I always like to know who is behind me when driving so i find myself checking my side view mirrors on corners. Like anything else you get used to it, I never feel unsafe because of it.

    Just when you are backing up, roll down you windows, turn music down, and do it slowly. Then listen for screams and horns, if there are none you are good to go :D
