how do i wire a 6ohm sub to a 4ohm amp?

Answer 1

The same as it would normally be wired. If it is a 6ohm sub it is probably a JL Audio sub they are company that started the whole 3ohm and 6ohm subs. JL subs generally sound the best when they are ran alone or in groups of 3 because of this. The way they are wired changes the ohm load on the amp but with only one sub it wont matter. Hope I have been helpful

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.

I chose Blaupunkt TSw1200 subs with a Sony Xplōd XM2200GTX and it moves my coffee table around when I'm in the driveway.

My amp is 1200 watts, subs are 600 watts
