New System, Expectations, Differences from last system

[cjcrook 10+ year member]

I am getting ready to purchase my new subwoofer and amplifier setup after not having anything for the last few years because it all got stolen.

My last system consisted of a Alpine head unit, 2 15" Kove Armageddon M series subwoofers, rated @ 500 watts RMS each, and I had them in a sealed box in the trunk of my 1998 Pontiac Grand Prix. My amp was a Crossfire BMF1000D.

I still have the same car, and I now have an Alpine CDA-9855. I have pretty much decided on a singe 12" RE SX D2, and building a 2 cu ft slot ported box tuned to 32hz. For the amp I am looking at a US AMPS Md1D or soming of similar quality that puts out 1000-1200 watts RMS @ 1 ohm.

My question is what are the differences in SQ, SPL, etc. that you think I will have with the new sysem vs. the old?

I'd say this system will be comparable SPL wise, slightly louder possibly.

SQ - Definitely better.

Should hit the lows better... depending on how low you tune your box however.

Anyone else have any thoughts? Thanks.

i would like to know how one 12 ported will get lower than two 15's sealed?

To the Op, sq wise, the last set up may be better and the spl should be about the same, maybe less

you speak of SQ but only mention subs, and amp, and a ported box... //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

truff, sq is not just the subs, but the overall set up including mids and highs

True. The mids and highs are staying the same for both setups, which is factory for the moment. I have plans to upgrade those in the future, but my main focus now is to get the bass back. I was only asking about the SQ of the bass itself, not the entire system.
