OK so I'm not really sure what details and what not someone would need to do this. I'm wanting to upgrade and have been told by numerous people that modeling is my best option to make my best decision on new sub's/ and or enclosure etc. I don't have internet access other than my phone so downloading modeling software is not an option I need help!

I'll give the basics of what I have if more details are needed I will provide assuming there is a kind hearted person who will help me out here.

2004 Pontiac grand am

Alpine mrx m240 wired at 4 ohms - 1500 watt which is capable of doing 2400 at 2 ohms.

Single slot port enclosure internal volume 4 cubic feet tuned at 32hz

Two alpine type r 12 inch subwoofer 4ohm DVc

0 gauge wiring.

220 amp alternator with 0 gauge power wire and negative wire connected directly to battery

Duralast gold top battery

Any other specific details I will gladly provide if needed. Thanks alot

#1.  List the exact volume your enclosure has (do all the math for how much your vent displaces, etc...).  If you are unsure about the tuning (as in you never verified it) list the vent area (internal Height x Width) and total vent length.  Do not use any metric numbers.

 

#2.  List the T/S parameters of the subwoofers you have.  (There have been a variation of Alpine Type-Rs over the years, you need to know the exact model number)

 

#3.  List the T/S parameters of the subwoofers  you would like to compare.

 

This will help whomever is willing to model for you...

Well I can't reach into the enclosure to get an accurate port measurement without taking out a sub so I'll have to wait tommorow or something to see.

That will help out a lot, making sure you get this nailed down is imperative...
