A single piece would be fine cause it is a shot distance so a small wire can handle alot more power. i have a single piece of 12 Awg on my and it is fine. How much power are u giving the sub and what AWG do u plan on using??

It is all up to the users preference and the specs on the sub. The lowest you could go is 30hz. Alpine says 33hz at 1.7ft for each sub. The problem with that calculator is that is doesnt take into account the displacement of the sub. So 3.4cuft would be internal area before port area tuned to 33 hz.

What are u trying to wire to it?? I was in the archive of rockford and all i seen for manuals were for the Punch, power, and prime.

The loaded BTL Would be louder and it would have a smaller box than the two SSDs.

Please dont use all caps!!!! Are going to port it or have it sealed?? Aswell are u after a powerful musical sub or and all out power sub for SPL purposes??

The battery you have under the hood roughly how old is it??

I see in your sig u have only listed equipment for a sub stage. So what im wondering is do you have another amp powering your front stage??

I don't think its the headunit ground but it wouldn't hurt to try it to see if it stops. Also like SSaudio said how and where do u have ur amps grounded??

The old school Soundstream amp were known for this problem. Now I dont know if they ever fixed the problem or not. The only way i know how to fix it is by wiring a toogle switch which would allow u to turn off the amps b4 you even turn off the vehicle. Even over at DIY they put a delay inline with the headunit so the amps power down before the headunit. This switch would do the trick Parts Express. Just take your remote wire going to that amp and put this inline with it. Hope this helps

I really couldnt hear the pop in the video. So is it the front speakers or your sub??

Like Adrian and KU40 said is the best way to tune But if you want to do it this way instead of using a 0db tone use a -10db tone. This tone is a lot closer to what actual music plays.

First off those setting are part of the parametric EQ. The F is the Freq - the number you pick is the spot u cut or boost at The Q is the with the the boost or the cut Turn the extend off cause that acts as a bass boost You can mess with these to tailor your sound Hopw this helps

Just so you know the pics are not showing up.

I have heard a few stories about an amplifier getting grounded through the casing. Which is like blowing a fuse but not as easy to fix. Maybe this could be your case. Unfortunely I'm not an amp guru.

Now u know that all your electrical is a ok. So jus for laughs I would hook up the sony again to see if it works. Now also when u rehook up the sony I would wire it to 2 ohms. At least that way you are going to give them more power. If it still doesn't then the problem is the amp.

with the rockford u got the volume past 14 without going into protect?? also was the rockford a two channel amp?? if everything wotked well with the rockford i would rehook up the sony to see if it works now, if it still has the same problem then ur sony amp done.

by chance do u have another amp laying around u can try??

I dont think it your amp cause if it was the amp it would be in protect all the time so im leading it is something with wiring. Could u take a pic of the amp installed in your car??

so u have one of the subs + and - match to channel ones + and - on the amp right?? The subs could handle 400 watts rms each, So that gives u 800 watts total but the amp u have is probably only giving about 180 watts to each speaker. So where do u have the gains set as well as do u have the the bass boost off??

what kennwood subs do u have??

What focal comp is he getting??? Aswell what Alpine headunit is he getting?? And what is he going to use to power those speakers?? Also is there an opening leading into the cabin from the trunk??

I have a dual 1 ssd sub with the copper coil option in a 1.1 sealed box powered by an audioque 1200d. And im wanting more deeper bass and louder but trying to keep inline with my sq setup. Would a sealed enclouser with more power? Do I port the sub and keep the same power? If i would port the box what cubes would u guys recommend? The space want to put it is 15.25H x 12D x 31.5W these numbers dont included the thickness of the wood and the double baffle. I could put it in a different place if i cant get it to fit.. And What freq would u tune the port? Thanks for the help in advanced.
