Newbie needs help!?!?!?!?

Question

I just bought a pair of kicker c12 comp subs http://www.crutchfield.com/S-GpJ1aOQhQjU/cgi-bin/prodview.asp?i=2065C124 and a memphis amp my friend said he got it for 250 not to long ago but it says power reference on the top and looks like this http://www.caraudiofield.com/ProductImages/16-pr150.2_thumb.jpg
Can anyone give me advise about what to do to not bust my speakers and to also how to optimise my system? I would appreciate it!!!

i know he never told me what the model was

the amp model and specs are shown here

Answer 1

Your speaker information comes up but the link for your amp does not give up any details. It just shows a picture of the amp. You should add the model number of your amp. Then we can compare the spec's for the two. You can do this in your detail box.

Good Luck

Answer 2

Ricky is right.
The max power per channel the amp is 100W , compared to 300W peak handling for the speaker. If anything it's under powered. Kicker does make some solid woofers.
Since you've got two channels and two woofers just hook them up straight 1 to a channel. You aren't going to gain anything by bridging or paralleling in this case.
You may want to look into a band pass enclosure. You can get more volume for the power. Although that isn't the recomended enclosure...
The concern as always is to not run the amp when it's clipping. Keep the amp gain down so that that doesn't happen when the head unit volume is all the way up.

http://spkrbox1.spaces.msn.com/Default.aspx 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).

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

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

Try http://www.soundomain.com/shop you can find some really good deals, and this site is manufacturer certified. VERY IMPORTANT WHEN SHOPPING ON-LINE!!!

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 that holds two 12's. Also included are java calculators you can use to figure parallel and series values given Ω values.

My system

Blaupunkt TSw1200 subs with a Sony Xplōd XM2200GTX.
My amp is 1200 watts, subs are 600 watts each, cap is 1.2 Farad

SPL is about 112 db

Total cost(so far) = $410

Answer 4

Don't worry about it. Those subs can handle more than the amp can provide. You MIGHT be able to blow those subs if you drive around with the signal clipping for very, very long periods of time, other than that, just hook them, up and you are good.

Answer 5

That amplifier is not going to bust your speakers. At it;s maximum that amplifier is only going to push about 100 watts to each of your subs - hardly enough to damage them.

Answer 6

you can turn down the power on the amp then you are ready to go.
