then maybe hes mistaken

 

No I'm not mistaken but your right I didn't hit 145, it was actually 144.8 and it was in a 3 cu ft box tuned to 40hz and I drew that score at 43hz. I myself hated it setup like this so I ended up going to a 2.2 cu ft box tuned to 26hz for sq. In a 84 cadillac sedan deville. I ended up breaking the seal on the bottom half of the windsheild and it started slapping the front part of my dash. Old pile of **** car, I know....oh well. In the end I ended up pulling power back to buy selling the jbl crown and running a PG Tantrum 1200.1. Then I got old and hated the system beating the **** out of me so I sold it all(for more than I had in it)

 

And to answer the thread starters questions, 2 12 inch type r's will murder the single type x's output and sound damn good on the sq end of it. I'd go 2 Type R's with a older mtx 81000d or a jbl bp1200.1. Put the subs in a sealed box with about 1.50 cu ft per sub. It will be clean and tight while still getting decently loud.

I'd like to also suggest a pair of RE SE12's, they handle a lil more power than the Alpines but are honestly better subs IMO

 

did u come up with 40hz by tuning the box to the cars frequency?

 

no I threw 40hz in there because I figured it would be a good place to burp the sub at. I thought that maybe the sq would be livable but it wasn't to me.

26,000wmrs - and u used 2000 and got what u did with a 12.... i dont know why u dont compete

 

145 is very posible.... remember the old termlabs where reading louder than the new termlabs.
my favorite setup so far was my old 2 15inch REaudio SX tuned 34hz pushed with a orion 2500D unfortunatly i never got a true reading on the setup.... highest i got on the meter was a solid 140.db new termlab with the port breaking loose at the rear and my cd broke literly 30seconds before my time to compete so i had to compete off the radio at what ever song was on at that time
wish i still had that setup. and wish i still had my old XXX 18inch sub with same amplifier. that sucker was loud and i loved them both!

 

145 is possible with a 12" w7 addiction?
