Basic Audio Upgrade ....

I'm planning to upgrade my audio to beginner's level.
This is what i've collected so far.
Got the Pioneer TS-EWX310 1000W 12" Shallow series.
Planning on Pioneer GM-6400F 4-channel 600W.
no capacitors.
No change in HU.
planning to hook 2 channels to rear and will bridge 2 to the subs.
Am I in the right direction??
Do I need Capacitors? or My stock battery can take care of this config?

Mine is 2007 Cobalt 2-dr W/stock audio - 4 speaker system.
When I saw under my rear speakers it says 8 ohms. Till now I' ve heard
everyone saying 2 or 4 ohms. What does 8 ohms mean? can I use these sub/amp?

Some says stock speakers cannot handle these amps.
My main goal is to add the subs. I'm going for a 4-channel just in case if i plan to upgrage the rear speakers in the future.

I know there has been a lot of similar questions.
Just trying to make sure of my investment.

Thanks.

first off, check the RMS rating of the amp, and at what OHMs. it might say 600w but most likely that is the max power:
General
Brand Pioneer
Model GM-6400F
Amplifier Channels 4 Channels
Power
Max Power 600W
RMS Power 60W x 4 @ 4 ohm


75W x 4 @ 2 ohm
Bridged Power 150W x 2 @ 4 ohm


next check the RMS on the subs:
Watts MAX. Music Power 1000 Watts
Watts Nominal Power Handling 250 Watts

Frequency Response 20 Hz to 114 Hz
Sensitivity 91 dB
Ohm Rating 4

i could not find the the exact model you specified so i choose the closest 1 off of Pioneers website.
So how many of the subs are you going to run? i wouldnt reccomend more than one per bridged channel with this amp. it would not have enough power to run a pair of subs and your back speakers properly. most likely you would get some distortion.

if you keep this amp, i would run only 1 sub in a good box and invest in a decent pair of rear speakers, but a monoblock single channel will work better for the subs. Also, a capacitor will help out the system, anywhere from 5-10 farads will help keep the lights from flickering.

unless the factory HU has RCA outs(i dont believe it does) you will need to get line converters for the rear channels. dont skimp on these, some of the cheaper ones can give you noises such as a hissing sound or anoying whirring electrical noise.

OHM DEF:

ohm [ ōm ] (plural ohms)
noun
Definition:
unit of electrical resistance: the SI unit of electrical resistance, equal to the resistance between two points on a conductor when a potential difference of 1 volt produces a current of 1 ampere.
Symbol Ω


hope this is helpful.

all i can tell ya is that ohms means resistance ( i think). its somethin to do with voltage lol.

basically all you need to know is the output of the amp and the max power of the sub and you should be ok on this sort of set up

Thumbs up Mono block

Thanks for your input guys. Now I'm thinking of a monoblock for this sub ( this is a single sub) and get a seperate amp when I upgrade my rear speakers.

Pioneer GM-D7400M Monoblock with RMS 400W @ 4ohms . The sub is 1000W PEAK @ 4ohms.

Thanks a lot.

you can rig up any amp to work with your sub. why not run this one til you get new speakers and get a new amp then?
