Can anybody tell me how 2 10" Audiobahn subs in a bandpass (not custom) would sound hooked up to a Profile 600x1 4 channel amp? Would it sound better in a bandpass, sealed, or ported box? What is the best place to set up the amp? Under the seat or in the trunk?

 

It would sound like crap in a box, but it would probably be loud...

Personally, I'd get 2 Image Dyanmics IDQ 10's (should be able to find for < $100 each) and something like a US Acoustics 2150 amp (450x1 RMS for ~$250). Then another $100 or so to get a proper sealed box built by a local shop. Bandpass boxes are loud and efficient, but only around a certain frquency (usually about 45 Hz), so you tend to get loud booming sound but only for a small range of bass and it hardley ever sounds good. They're also incredibly hard to design and almost any pre-fab one you buy will not be properly designed, not to mention that the design is completely dependant on the sub. It would be best to buy the subs from a shop that can build you a box (a real shop, not like best buy or circuit city) because they know the specs and can build a proper box. But if you get the recommended box volume from the sub manufacturer, any shop can build you a decent box.

And don't buy a profile amp, that thing may put out 600 watts right before it blows up when fed a 24 volt input signal while being sprayed with liquid nitrogen and fed a single tone signal...

 

Ouch! So harsh, Chad.

 

Yeah well, I call it like I see it

 

Those profile amps are overrated. The 600x1 is probably at two ohms at it's peak wattage not rms. And since this amp probably isn't two ohm stable, then the spec is crap.
Your best bet is to make a sealed box (the easiest and most forgiving of mistakes) with the known volumes recommended by the manufacturer. Also, make sure to make two chambers within the box to seperate the subs, this allow the speakers to respond independently of each other. Your 600x1 number is nice, but how do you run a four channel amp down to one channel? You can run it to two, but not one. So you should have the amp bridged to two channels and run one channel to each speaker.
I realize that money is tight for most people, but sometimes it's better to save up and buy better equipment. I've had some low quality things, and they usually break after a year or so. Since I've bought high quality stuff and everything has been running strong for over four years. I've also got some great deals on my stuff, so that helps.

Stereo:
Front: MB Quart Components
Rear: MB Quart Coaxials
Amps: (2)MTX and one unused Blade
EQ: Cadence 7 band parametric
Subs: (2)JL Audio 10w6 in personally made box (with help of my uncle who's a carpenter)
Head: Stock, until the Aiwa CDC-MP3's are in stock

Sorry for the double reply, the server was giving me crap.
