and ricky i m still waithing for your respond

Answer 1

Ha ha! You put in subs with no box, and you are wondering why you have no bass. Sorry, I just thought that was funny. Take it to a shop man. You probably have the gains turned up WAY to high on the amp, that is most likely the cause for your distortion...

I tried to reply, but your email address is not confirmed.

Look in the manual, and it will tell you where the gains are. Turn them down as low as possible. The gain is not a volume knob. It is for matching the voltage of your deck(or line level) the that of your amplifiers input rails.

Give me the Brands and model numbers of everything in your system, and I will see what I can come up with.

Answer 2

Wow, ok first of all, the subs have to have a box to make bass. Why else would people put them in a box? Make sure that the box has enough space to properly reflect the bass. Refer to the subs manual or check it out online to find out what size box you need. Are your 6x9's able to handle the power your amp puts out or are you trying to use your factory 6x9s? If you need more info, contact me... I've installed tons of these.

Answer 3

You need the subs in a box and a crossover to run the subs and 6x9 on the same amp. The setting for the sub will be different then for the 6x9.

Answer 4

Sparky, your system absolutely blows and no one cares about your really really low and crappy SPL results. I could hit 120db with a factory 6x9 for $20 bucks. Quit posting that crap like it's cool. Sony anything in car audio sucks, just like your entire system. I know you're trying to help someone build a box but do you have to post that crap every single time?

Get a life.

Answer 5

http://spkrbox1.spaces.msn.com/ for real "sound" advice.

Your system won't mean squat without a well designed box to put your subs in. Some manufacturers have recommendations as to dimensions of various types of boxes. It is best to find someone who builds boxes if you go with something other than a sealed box.

You should always match up RMS (Root Mean Square) watts of Subs and amp per channel as well as impedance's(resistances). When a sub has rating of 600 Watts MAX it really has an RMS rating of about 200 Watts RMS. RMS is the nominal wattage your most likely going to get out of it. Remember, a 200 Watts RMS amplifier has more power output than a 200 Watt MAX.


If your amp is rated at 4Ω don't subject it to 2Ω, it will fry.

Here is the formula for subs in parallel:

Z = 1 / (1/sub1 + 1/sub2 + 1/sub3 + ....)

For series, just add them up (sub1 + sub2 + ...).

You can mix and match these equations to get the right impedance required by your amp.

Example 1: Amp is 2 channel and rated at 4Ω, 4 subs @ 4Ω each. If I connect two in parallel and the other two in parallel and connect the two pairs in series, I would have a total impedance(resistance) of 4Ω. So to the amp, it's just one sub.

Example 2: Amp is rated at 1Ω mono, 2 subs @ 4Ω each dual voice coil. If I connect two voice coils in parallel and the other two voice coils in series and connect the two subs in parallel, I would have a total impedance of 1.6Ω. Which would be perfect for a 1Ω stable mono amp.

You should use a capacitor as well.

Recommend for every 500 watts MAX you use a .5 Farad cap
Example: 1000 watts MAX - 1 Farad cap

You will also need what's called a "line level converter" if your stock head unit doesn't have RCA outputs or your amp doesn't have high-level inputs.

If you like I can send you some plans for reference. My plans are for a 4-th order band-pass bass box (A.K.A. bass-reflex) that holds two 12's.

Also included are java calculators you can use to figure parallel and series values given Ω values, tips on box building and types, calculating port diameter and length(if used), calculating box dimensions for types of boxes (sealed, wedge, cylindrical, etc.), materials needed and even how to make a jig for cutting perfect holes for your subs.

Just e-mail me [e-mail]

My system

Blaupunkt TSw1200 subs with a Sony Xplōd XM2200GTX.
My amp is 1200 watts (200 Watts RMS X 2), subs are 600 watts (200 Watts RMS) each, cap is 1.5 Farad

SPL is about 112 db each sub

Total cost(so far) = $410

gt_ryder13, I'll take you up on that offer...

"...could hit 120db with a factory 6x9 for $20 bucks..." and have it sound GOOD, I don't think so. It's not about the SPL. It's how WELL it sounds without distortion (which I'm willing to bet your system is noting but distortion.) In fact, your the one going down the street with your whole car rattling and sounding crappy.


whip it real... umm I gave an answer...your just a waste of space. Go chat on some board for dumbaѕѕeѕ, you'll fit right in.

Answer 6

Its not the equipment, or anything. Everything is working how it should. The issue is you, have have build up such a tolerance to the sound that it doesn't affect you as it original did. The fix for this, is to start your third sound system upgrade. Make it louder, add more speakers and subs!.

Answer 7

Unless the subs are free air and mounted in a baffle, they should be in an enclosure. See Sparky's information.

Answer 8

woofers have to be in a box of some kind. did you buy the amp new? could be defective.

Answer 9

i guess i am not the only one annoyed by sparkys one size fits all answer

Answer 10

yeah you did, you need to quick while your ahead, and give it to me so i can finish the job and charge you money haha
