What do y'all think? Will this work? Need feedback ASAP.

 

Thanks in advance.

Damn, i dropped the ball on this one. Box dimensions per the manufacturer shouldn't affect frequency response that much as long as the same box type is maintained. Basically if it's sealed you can deviate a little, maybe 30% before you notice the enclosure sounding a little weird. It will also depend on box type. Sealed boxes are normally pretty forgiving with deviation from specs, bandpass requires maybe 15% deviation, and a ported box requires very specific measurements to get the desired output. I would say within 5%.

He needs a cap asap to spare the alternator, his car was dropping below 12 volts on big bass notes. Once you start pulling 110% of an alternators rated output, it's a matter of time.

As a bandaid, put a 1 Farad cap in line going to the sub amp. IF he's planning on two amps, get at least a 5 Farad supplying both. The battery looks good, he just needs to get the right supply power before he starts rowing through alternators. You can find the 5 farad caps on ebay or special order from Best Buy (last time i checked) for a couple hundred or less.

 

As an alternative, you might was to see if the local car audio shop sells Ohio Generator alternators or Stinger Alternators. They will be expensive, but they can be rewound to supply 14.x volts, but at a much higher amperage level.

why would he gewt a stinger amp when it is a ohio gen. alt anyway (plus 100 bucks)

 

if hes going to spend 200 bucks on a 5 farad cap, dont waste the money and just go with the HO alt

 

 

Easier to get warranty swaps in person if it should fail.
