Want this question answered?
no you can't. if you want to run separate amps for your subs they both have to be the same amperage and preferably same model. you can use the 1000 w amp on the subs and get a nice amount of bass depending on what size and model subs you have. then just use the 400 w amp for your mids and run the highs off the radio lines. try that and you will hear some good sounds. you will also need a crossover as well. hope that helped.
It's so you can use your stereo speaker output wires to the amp without having to use RCA cables It should say High Level Input and you use it or RCA cables. Not both. If you plan on using the amp to power subs use RCAs. If you plan on running mids and highs you can use what you like. If your stereo has front and/or rear RCA outputs as well as sub output it's your call
Did you get the 2 ohm or the 4ohm? I have a 750 mono on my single 4ohm and have no where near enough power.
this monoblock amp is bridged internally. It can handle a minimum of 350w RMS one channel and a maximum of 700. I'd suggest letting a mono amp power a single sub for best results. But people do use it to power 2 10 inch subs as well.
theres no point in putting 2 subs then... 1000watts would be divided between the two subs giving each 500watts. since the subs are rated at 1262W you would only be using about 40% of what theyre capable of. I would say use only one of the subs or get 2 amps. although with 2 amps you wouldn't get to full power you will be pretty close. But if you only have one 1000W amp then having one of those subs will give the same sound as 2 of them. however, 40% of 1262W is still alot of power. ^^Look at the RMS power, not the rating of the subwoofer. You can run this behind 1000w just fine. I ran one with a Kicker 500.1 and loved it!
Class D
4 + 4 wired in paralell + to + and - to - will give you 2 ohms. do this on both subs and then wire them together + to + and - to - and that will give you 1 ohm. so now get an amp that is 1 ohm stable 95% of mono block amps are. add your subs rms wattages together not peak let say your subs are 1200 peak and 600 rms then 600 + 600 equals 1200 watts rms is what you need. so for this instance i would need a 1200 - 1500 watt rms mono block 1 ohm stable amplifier. I like more power just in case after the subs get broke in they want more power.
Depends if you are building heavy bass system with quite a few subs then a mono amp would be suggested but if it is just a single sub just for a standard bass upgrade then a 2 channel amp would be fine you can still use a mono amp on one sub just remember to take into perspective the RMS rating and the Impedance on both the Subs and the Amp
it depends on alot, alot of things. but id say to be safe a 2000 watt. but the best amp would be a sundown saz1500d
When buying an amp its best and safe to use the 1:1 ratio. That would mean if subs RMS was rated at 350 watts then get a 350 watt amp. Alot of installers will use 3:1 ratio because the subs max rated at 1200 watts so they say you will need a 1200 watt amp. But the truth is that sub may only peak a fraction of a millisecond. So unless your competing for a title championship there is no need to destroy you subs that you paid so much for.
dude you just need to get a bigger amp n a capacitor...i got a 1600watt pheniox gold for my two 12in cvrs n that powers them plenty. yes u could use a bigger amp to solve ur problem but the reason is most likely the ohms its probably unstable but i would need to know the way that u have the subs and amp set up together.
It's always a good idea to have a much more powerful amp than subs, that way you have a little bit of room to play with without maxing out your amp. So, either a 2800 watt amp, or a 3000. Although, something smaller wouldn't hurt either, a 2000 watt amp would be just fine. Make sure that the amp is only a two channel, if its a four then that means you'll be wasting power on two channels you would ever use, so if you get a two channel, the amp will be strickly dedicated to just your subs. BUT! with that much power, its always a good precaution to upgrade your battery wires, which are proabably standard 4GA to maybe even a 0GA or 1 ferad. Then maybe install a Capacitor. These Precautions will prevent your alternator and or battery from going bad. It sucks having to change your car battery every couple months, believe me. Good luck
