I dont care about SQ I want SPL How?

Not trying to piss in your cornflakes dude, just see it from our side of the fence is all. There are just too many ways to get burned by an e-tailer and sadly it is becoming a bigger problem every day. An e-tailer cannot answer your question that you just asked but I can.

There are many people on this forum that are not industry experts but for the ones that have been around long enough on it to learn from us, can also answer this question as well. There are also those that you have no idea who they are and what basis they are making their judgements on. This is very dangerous on your part. If you take the advice, make sure that it is credible.

What is wrong is for you to find ut, hopefully you don't but when you do, you will understand further.

PS -  the free advice column...... a 4" can hit the same low frequencies as a 15", it just cannot do it with the same amplitude. So to answer your question, there is no difference as well between a 10" and 15" in low frequency response goes except for the amplitude (or how loud the subs ability to play that low frequency is). Bigger does not mean better, not by a long shot. Now that I have answered this, do you think that a e-tailer would explain this to you or would he sell you what you want insted of what you need and then have the basis to back it up?

95pony as a newbie you should hang around a while before you start slamming the regulars.

Forbidden is of course correct.  Woofer size has nothing to do with how deep a speaker can play.  And to the larger point, if you buy from an on-line non-authorized seller, expecially off eBay, you do so at your own risk.  If you know what you're doing it can be ok, or if you are able to spend money on gear that may be trash.  But if you are a beginner (and you appear to be) or if you have limited resources, it is dangerous - assuming you want your gear to last longer than this weekend.

The only thing I can recomend in the eBay link you posted is the Autotek amp, and maybe the wires.  But I cannot recomend you buy it from an eBay seller.  Go shopping in your home town, support your local professionals, and you may be surprised what you can get for your money.

first of all, i'm with these guys, buying equipment from a competent shop and buying sh*t off ebay or whatever are completly different, etailers sell refurb, damaged, or old equipment, they have no knowlege and usually just buy out old company's stock from 3 years ago, and sell it at 5 dollors over cost, you will never get any advice from them, nor will you get anything if you actually need to warentee something, it's people that are more worried about saving 20 bucks that ruin this whole bussiness for people who take it seriously,,

now by saying you don't care about sq, you oviously want something that sounds like ass, but you can hear the buzz of your trunk rattle for about a mile right? think that's really going to impress anyone over 13?,, sorry.. anyways, if that's all you want, get audiobahn, chrome up the ass, sounds like crap, but it'll thud, if you want to get serious, look around at some shops, find a dealer who will sell you a good set of subs, and a box that actually goes with them, instead of buying subs ment for a 1 cube box and then having your neighbor build a 10 cube one out of plywood and drywall... look for a respectable brand, find a dealer that is licenced with them, they will get you a better deal.. don't go to flee markets, and get a few components that match each other, you will be happier with a system that sounds good, because a "loud" system made up of junk, will not impress you for long, you need something that acutally hits like its suposed to,,, If you end up getting junk you'll be one of the kids that listens to that ONE song he found that makes his system sound half way decent, and when your still listning to a 5 year old lil john song because everything else distorts, you'll wish you hadn't wasted your money,, my .02
