box too small?

hello. i have a 12" alpine type-r; mrp-m500 powering it. i have the sub in a ported prefab box. its really loud inside the car but the bass is not loud enough for me outside the car; the bass doesnt travel so far. i want to be heard at least a block away. im running a 4 gauge power wire from the car battery to my cap and (2) 8 gauge power wires that split from the cap to my mrp-m500 and a rf punch 240x4. the mrp-m500 and the cap is a 4 gauge ground. and the punch 240x4 is an 8 gauge ground. and im running 14 gauge speaker wire for the sub inside and out. here is the link for the box. im having trouble posting the link on here, if you can do me a big favor and go on ebay and copy and paste this in the search bar: 360173767209. sorry for the inconvenience. thank you very much.

Sorry never hear a 12" alpine type-r a block away in any box. The box is good but still not going to hear it that far with 1-12" alpine type-rCan't be loud then don't have it.

ported boxes dont carry well over long distances unless it is a big setup. i have my 18 in a ported box and it does 150db on the dash but if you step out of my truck you will barely hear it a few feet away. my suggestion is maybe try out a sealed box.

what are good subwoofers strictly for loud bass?

i guess i didn't tell you what you wanted to hear.   your type R can get plenty loud with the right box.

the right box? you mean a custom box right? how can i get the cut outs? i would have to measure my trunk right?

The right size box for the sub if you was to buy it, but if you was to build it your self then you would need to measure the trunk or where you are going to put it. (while even if you buy it you still got to measure the truck to make sure it fits. I am a little confused on "how can I get the cut outs?" please explain a little more (cut outs of what)ex: holes, a cut sheet for the box. Need more info.Can't be loud then don't have it.

Bass travel...JL Audio...hands down. Broadcast some highs too! Just no rattle!   The M500 is not a easy amp to work with, the separate controller is cool though. Consider the amp can exceed 900w when choosing your woofer.This is what I do for FUN!

900w ... meaning 900 rms right?

No, rms is 500, the amp draws around 35 amps on a semi-consistent basis. When I had the MRD-M500(not MRP) with the RUX control module, I saw the current rise to over 65-70 amps frequently, and even higher on occasion. With a Zapco preamp, I pushed 2 DA 12's. Taking advantage of the 8v RCA input.This is what I do for FUN!
