what about under a seat? just make sure that it still gets some air, and it sould work fine. but i dont know what kind of amp it is, or how big it is so its hard to say. you might have to bight the bullet, and spend $1 a foot for some 4ga wire.

What casaudiotc is trying to say is put it your trunk, I think. He rambled something about more power wire and left you hanging.

Be sure to match up power wire guage with the power requirement of your amp. Ex. 1000 Watt amp - 4 AWG wire.

Ground wire needs to be as short as possible (ground it in your trunk, 18" in length or less is ideal).

To save money you can buy jumper cable wire (looks crappy, but works).

I have more info in my "hook up" pick at the bottom of the link below.

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).

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.
Just e-mail me sparky3489@yahoo.com

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

You need to buy more power wire. Don't try to half-a** it. Do it right the first time, and you'll avoid any potential problems you might have in the future. Amplifiers need circulation in order to stay cool - and with the limited amount of space under those seats, it will simply overheat and continue shutting off (thermal protection circuit).

Go down to your local retailer and get yourself an amplifier power wiring kit. Depending on the make/model of your amplifier, you might be able to get away with using wire as small as 8 gauge (which will also save you money).
