Throw an hc1400 up front and call it a day! my 97 astro has the original alternator on it and it's around 12 years old now.... Solid little beasts, as far as the battery put a stronger one up front and it should work out just fine. You can still add the cap at a later time if needed.

will it help if i use 0 gauge cables? or 4 gauge would be ok? and for the subs 8 gauge right?

0 guage is the only way to go especially when running much over 1000 watts over a length of the vehicle off the stock battery and alt.

The astro engine is so compact and small as far as the runs from the alt to battery and ground ect... I don't think you'll notice a difference to be honest. The factory wire on my astro was 4 gauge. Running 0 gauge to the back I would recommend. 8-12gauge for speaker wire

you should deff be good with what you got. if its one amp you are fine, its not tremendous power but will do the job, and as long as thats all youre runnin have no worries. now once you add another amp for your mids and so on you will need some more power, until then just sit back and relax while the bass hits.

theres always work in progress

wouldnt even worry about a cap.....just my belief....but they are just over priced volt meters.
