Multiple Amp Hookup

How would I go about hooking up 2, 400watt amplifiers together to make there be 800 watts to the sub ?

Most people just buy the right amp ;)

its not a matter of the right amp you can make a design with 2 amps that look cool.

If you just care about the looks of it, why wire them up at all, just mount the 2 amps, and the sub and it'll look cool. Honestly if you want it to sound good, get an amp thats matched to the sub you wanna run. In this case, function or form my friend.

You could run dual subs, 1 amp per sub and then just run it that way. Technically, that's correct AND it would look cool. What you're talking about isn't just "wrong", it could overheat one of the amps and possibly cause a fire.

Anyone know how it hooks up ?

i don't think i have ever heard of someone hooking up 2 amps to one sub. just sell one amp and get your money back or buy a next sub and wire one amp to each sub

I have 3 subs but there all hooked up to one terminal in my box , I wanted two amplifiers to make a custom design and since my box is so huge I find two would match close to the large box .

Isn't it usual for an amp for say subs another amp for speakers?

Really there is no good way to hook them up. Are they the same amp? There is an article in this months car audio and electronics about this very topic but this is for a dual voice coil sub.
The problem is that both amps needs to have the exact same output voltage, which you need the gains matched. Not easy to do with multimeters and a proper sign wave disk, plus ensuring the deck is set at the oprimal volume level, if not you will cook the amps and the sub. Really this is a bad idea, will lead to a lot of damage. Hook 1 amp up leave the other for show if that is the way you want to go.

Well I would consult a proinstaller to set them up. Likely they would not want to do it,
A little higher voltage output on one amp and both are cooked. And be careful Im talking speaker level voltage not wattage. Then gain controls on the amps must be set exactly the same. Again highly not recommended. David

You'll still never be able to get them set-up exactly the same. If you really want the 2 amp look, why not use one amp for the subs and get a second amp thats the same size for your speakers and amp those.

Well the amps im looking at are 400 watts and that is not enough to push my subs with just one, if you guys think that it is a bad idea then I will take your advice , can someone explain to me what a capacitor does ?

A cap hold a short burst of energy and can recharge quickly, usually used in conjunction with sub amps. It keeps the voltage to the amp more consistant. Most people feel these will help with dimming headlights
As for your power, do not limit yourself based on the subs ratings. A 400 watt amp will push most regular subs. You should be worried more about the distortion of your system. Ive had good quality 100 watt amps pushing 1000watt subs just fine. David

Well you guys seem to know quite a bit so can someone try unscramble some things for me lol
http://www.obcon.com/ Thats my type of sub as discussed in a later thread and Im looking into a 400 watt amplifier so how should I go about hooking it all up so I can get some hard bass, In my past car I had two 12inch pioneer 400 watts a piece hooked up to a 365 watt kenwood amp and it didnt seem to have that much bass compared to some cars that ive heard . Should I put a 400 watt bridged amp to my 3 10 inch obcon subs with a cap ? Hany hints welcome im completely a rookie on entertainment.

Heres the problem with 3 subs you divide it so each sub recieved 1/3 the power of the amp. The other thing was how were they wired. Its would be about a 1.3ohm load assuming a 4 ohm speaker. Which for a Kenwood amp is likely to low. Now that is very technical basically that amp is not built to handle that load. Now if you wired the subs where the positive and negative teminals are hooked up oppisate then the subs could be canceling each other out. There are so many variables that can effect out put. I would need a list of all components in the system plus how they are all wired.

my new subs are all connected to hit at the same time
