I have a 400w rms @ 4ohm sub. What amp do i need? If i want to connect it via 2 channel, bridgeable amp, what wattage does each channel need to be? Do i need a second amp for 2 6x9s?


almost any amplifier amp would push a 400 watt sub. try to stick with a name brand, and steer away from no name brands like boss, jensen, etc.you will only need a 2 channel amp to run your sub.you will need a second amp to run your 6x9'sor you could get a 5 channel amp, and run all your speakers, and the 5th channel for your sub

My stereo in 1997 chevy caviler is turning off and on when turned up to a high volume. I have a sony xplod 52 watt by 4 channel radio. With two 6x9 sony xplod 50 watt rms and 300 watt peak power in the...


Most likely cause is heat. The clearances behind the radio are often not sufficient to provde the proper air coolling that the higher power radios need. The heat sinks on the rear of the radio require a certain amount of air flow to dissipate the heat generated under high load conditions. If you add summer heat to the equation, you can have the radio going into thermal cutout to protect it circuity.

I have my amp hooked up right to two 12 inch subs but the red protect light comes on wht does this mean?


Check all your cable work.
Power is connected tight? Ground is attached tight - on both ends (my guess is it is the ground) Remote cable?
Is the ground a proper ground?

I have two 12 inch rockford p1 punches powered by an 800 watt sony explode amp (2 Channel) and i want to install another 15 inch kicker with a 1200 watt amp not sure the model, i got it from a friend and...


I have a similar setup & I just run the second amp straight off the other amp by running positive & remote wires directly from 1 amps positive & remote inputs to the others amps inputs. But my head unit has RCA inputs, (sub in & front & rear inputs) so from my 4 channel amp I run 2 6 inch alpine S's to the front to the front RCA inputs of the head unit, & 2 Pioneer 440w 6x9 inch speakers to the rear inputs. & my 800w 12 inch sub from my 2 channel amp to the sub woofer inputs on the head unit. Has blown my eardrums for nearly 12 months now great stuff! Hope this has helped

Can you power 2-10" subs and 2-6x9 speakers with this amp?


You could but the only problem is even if you ran the speakers in parallel, meaning + to + and - to -, the best power you would get out of the amp is 230 watts per channel. Would probably make your 6x9 sound good but not enough to push your 10's.

I have 2 6x9 speakers up front 4 6 1/2 3-ways


Hello rjmiller4039,

Although amps with 5 channels are pretty rare, you can get one. Alpine, Boston Acoustics, Infinity, JL audio, MTX, and Polk all have 5-channels ranging in price from around $350 up to around $1,000. The Alpine PDX-5 will output 75X4 watts RMS for the front and rear stereo channels and 300 watts to the mono sub channel. It is priced at $599.99 at Crutchfield.

Hope this helps.

Speaker amplifier calculation


for $85 i can sell you an Almani 900 watt 2 channel amp i would stay way away from those 3 brands they are all really poor quality and i can get you any major name brand cheaper.
I can get you a hifonics 4008 amp (800 watts peak 100 watts per channel rms) for $100 shipped with full factory warranty. you find an amp you like and i will get you a price. I am a factory wholesale distributor for most brands.

Will this amp push my speakers


Whoa, I do belive your rating for your speakers are inflated. I have never heard of a 6X9 accepting 800 watts thats just rediculas, its more than my 12" sub needs. Anyways, if this amp is anywhere from 300 to 500 RMS watts you will be fine. Because the speakers are small they need very little wattage to reach there potential, usually less than 100 Watts each, and probably around 50. If you think about it most decks put out 50Watts max for each channel, because that is the max you can assume that the RMS wattage of the unit is only around 20-25 Watts of power per speaker.
