Hi, new to the forum here, and also though Im a handy capable person, Im still a noob when it comes to the technical side of car audio, pretty good at putting stuff together though.

sooo question, ive had my amp for over a year and just got the 12" pioneer champion series TS-W308D4.
i have it in a sealed box, i just bought the build it yourself 1 at walmart, the dimensions and info are:
1.25 Cubic Feet
18.5 x 18.5 x 14.8 inches
Im running the sub at 2 ohms, this is my amp in case u need the specs on that..

so far these are my settings:
input level: i put it up 2/3 (that was recommended on a forum i found while googling)
subsonic filter: 0
low pass filter:105HZ
bassboost:0

are the settings okay for now? should i change anything after i break the sub in?

I'd say for starters, set your low pass to like 80 hz. subsonic filter at 0 isn't a problem, setting it in the 20's doesn't hurt, but at 0 it shouldn't make a difference because of the frequency response of the amp. as for the gain, I can't tell which amp you have but just setting it at 2/3 probably isn't a good idea. if you're free thursday night theres a thread about a test and tune in concord, come by and introduce yourself. I'm sure someone there would be willing to help you out.

Welcome to CCA......

Unfortunately the link to your amp specs doesn't work.....the gain setting sounds higher than it should need to be, how are you providing the signal for the amp? Aftermarket HU with RCAs, factory deck with a line out converter or something else?

The Test and Tune in Concord would be a perfect place to bring your car to get it checked out......hope to see you there......

maybe that will work??
its the planet audio TQ1201
thanks for the replies, I'm going to change those few things suggested in a second. I noticed the subsonic was actually at 15, since thats where mine actually starts.
Also its an aftermarket with rca pioneer headunit.
which brings me to another question, do i need to change the settings on the headunit as well?? the HPF??
I wish i could go to the test and tune, but i have 3 kids with me, not sure that would be much fun for them or the adults either..lol.
and my stereo isnt anything fancy, I got my car 2 years ago with a cassette player and 1 working speaker, I basically switched it myself on a budget of 600 maximum for everything at the time. Saved money by installing most of it myself. Only paid to get the wire ran from my battery to the amp.

If you are going to use the Xover in the amp you can leave all the Xovers in the deck set at 0 for now.

Set the LPF on the amp to around 80hz or so, set the subsonic to around 30hz, unplug the RCAs to the amp and listen to something you know really well. Since you are running the mids and highs off the deck, they will determine how loud you can turn it up without introducing distortion into the signal. Once you have found that number you can hook the RCAs back up again, turn the gain down to 0 or minimum and raise the deck volume back to that magic number. Now you should be able to find the point where your sub starts to distort and turn the gain back down a touch.

You have now found the settings that let your system play as loud as possible without distortion. Anything you do to try and get louder will involve new equipment with more power or worse sound out of what you are running now......

soooo, my lows sound fine, but the highs make the sub distorted.
also how long, hour wise, do you think think it would be safe to turn it up?? ive been keeping it down in fear of blowing it...

how does that wal mart box sound i was thinking of getting it for my gf for a starter kit

Ewa

it sounds fine to me, i just sealed the inside with some silicone.
it actually got good reviews..

The highs can't make the sub distort, but when they do start to go they make the whole thing sound bad......remember you are running them off the amp in the deck (unless I missed something....) and it will never be able to keep up with that much bass.

For louder cleaner highs you will have to throw an amp on them, you are more likely to blow your highs thru distortion at the moment than anything else.

If the system is setup correctly and you are not causing distortion by over-doing it on the volume control, the sub should play all day long with no ill effects.....
