SHOULD I GO AHEAD AND BUY A 400 WATT AMP?

you shouldnt run it at 8 ohm it shows what ohms it can handle . to run it at 1 ohm you would need 2 subs to do this. and no i wouldnt run an 8 ohm sub on the amp.

I have a 1100 watt sony xplode the silver one 4 ohm rms 3 00 with a 3000 watt 400 rms pyle amp? 8 ohm

I am not sure how you are measuring the power output to verify it is less than 200 watts. With a true RMS voltmeter you should see 28.28 volts RMS across a net speaker load of 4 ohms. If you use only one 8 ohm speaker, you will get 120 watts. If you are getting the 28 volts there is nothing wrong with the amp. You MAY have blown the speakers OR not generating much bass due to processing in an EQ. I assume you are using at least 15 inch speakers if you want to feel bass. Look up your speakers specs... you will need speakers capable of 32 Hz to feel much. With this amp your speakers should have aa total rating not less than 400 to 600 peak watts or around 300 watts RMS continuous power rating. Using a lot of high end EQ will keep the amp busy at the high end and reduce the power available at the bass end.

rca cables for audio and a remote wire. just plug the rca cables into the plugs in the back of the deck and the remote wire (i suggest buying a thicker (speaker wire size) gauge wire since it allows you to get more power out of the amp) to the blue remote wire coming from the deck. you will also need an 8 gauge power wire (12 inches to 12 feet depending on where the battery and amp are) and an 8 gauge ground wire (no longer than 24 inches).

your drawing/pulling too many amps. Is it a mono(one speaker), two way(two speakers/can be briged to one), or a four way(four speakers/can be brigrd to two). don't put too many speaker to that one amp if it's only a mono, or a two way.

any amp will work with any speaker, you just need to make sure it is a mono amp if you are running 1 speaker and a stereo amp wither 2 or 4 channel if you are running 2 or 4 speakers, the ohm rating on the amp should match the speakers also, on the back of the speaker it has the ohm rating, most will be 8 ohm, but you still find some 4 ohm, depending on the speaker if it has a lot of throw (the in and out movement) you may want a higher wattage amp so you get clean sound, it is up to you.... if you are installing lower price amps to you may hear engine wine or noise while car is running so a grounde loop isolator installed on the system will remedy that... also with the amp the directions will tell you the ohm rating of the wire to use, follow that.... and keep the ground short and clean where ever you put it.. try not to go directly off the battery cause you will get a lot of noise... hope this helps..

I know this is a very broad statement, but your budget will allow for what you buy. You will want a nice 2 channel 50 watt rms amp min. 50 watts is a lot of power for those speakers and you will be happy. I would recommend if your budget allowed a nice kenwood, Alpine, Diamond Audio or MB quart. Just make sure whatever you buy that it is a low noise A/B class amp. Nothing to special.

Take care and have fun!!

when in doubt go bigger, you might want to get a bigger amp down the road, so its better to not have to buy another wiring kit later.
and the bigger the wire the less line loss you will have so your amp will sound and perform better.

i would go ahead and have this one fixed if its new enough,,,its in the convergence board where the problem lies and would be cheaper than buying a new tv

400 watts delivered to 300 watt speakers the only way to do this would be to wire two subwoofers in series so that the power needed to drive them will be 600 watts to max, however this will increase your impedance on the speaker (8 ohms) load so what you can do to compensate is get an 8 ohm 600 watt resistor and put it in parallel with the speakers you will then have 4 ohms of impedance at a total capacity of 600 watts of power In other words the amplifier won't blow these out now.
