Which of these subs would you get?

[AndonD454]

personally im sure even one 15 will blow the old system away sq and spl... but abotu the 2 15s.. i would measure out your trunk before you consider it too much.. those 15 mentioned above require huge boxes if there ported (or sealed for that matter)

[threedd97]

I will probably go with 1 15" for cost reasons. I don't want to take ALL of my trunk space. I found a reseller of U.S. Amps and found these:

USA-1000
USA-1000X

Which is better?

[sr20de4evr]

The XXX you can buy factory direct from www.reaudio.com, they don't have prices on there but the 15" is around $430 shipped and the 12" is around $380 shipped. As for amps, the lowest prices for Cadence used to be at www.usacaraudio.com, but I have no idea what happened to that site. I haven't found a good replacement site yet, but there are a few authorized dealers on www.caraudioforum.com who can get you a good deal (you'll have to run a search on there though as I don't know who specifically the dealers are), and the lowest prices I've found for US Amps is www.speedsound.com

Were those 10's ported or sealed? Actually either way a ported XXX 15 will....god I can't even come up with a good metaphor, it's too late. Are the Cobalts the C-series? If so a single XXX 15 will have the same linear displacement as 8 of the 10" C-series, it will be absolutely no contest.

i suppose in my opinion.. the 1000x.. only because if youre buying a XXX or Brahma.. they will be dual 2 ohm... unless you talk to the company and specify otherwise.. and the dual 2 can only be run at 4 ohms or 1 ohm

You'll need more power than that for a XXX

but to answer your question, the 1000X would be better as it provides full power at 4ohm instead of 2ohm (the XXX is dual 2, it can only be wired to 1 or 4 ohm)

That is where I found the US Amps at. Great prices. Which amp would be better for one XXX 15", the Cadence or US Amps?

[sr20de4evr]

damnit I'm just too slow tonight.....

[AndonD454]

also, though, check those sites sr20 just gave because i think i would want to find a mono amp that was stable at 1 ohm to run the 15 with.. maybe 2 ch. is better but ive always been told monos are the best sub amps

[sr20de4evr]

well, I would rate US Amps slightly above Cadence, the problem is US Amps only has 1000 and 2000 watt models, the 2000 watt one would be better for the XXX but it's nearly $1000. In that regard I would say that Cadence would be the better choice, you can get a ZRS-8 or Z7000 for around $600, either of which would give you 1500 @ 1ohm

[AndonD454]

good suggestions.. makes me wish i had the money for an amp like those

[threedd97]

Sounds great. I guess I'm going with the Cadence 1500 @ 1 ohm with a XXX 15". The reason I'm penny pinching in a way is because it'll just take me that much longer to purchase a more expensive setup. Will I need a second alternator or battery? Or just replace my Walmart battery with an Optima Yellowtop?

[AndonD454]

i would suggest the yellowtop/redtop for sure.. not sure how many amps your alternator puts out.. but regardless i wouldnt suggest another.. but rather a rebuild or replacement of the one you have.. if necessary.. i dont know thats another couple hundred so lets see what sr20 says

[sr20de4evr]

what size is your stock alternator?
on a car that big I'm guessing it will be around 100 amps, that paired with a yellowtop and the magic 3 upgrade should hold you over. I have the same amp on a Brahma 15 in my car, on the stock battery and stock 80 amp alt. When it really gets going it will drag the system voltage down into the 12's, but at that level it's almost unbearable to be in the car, and that's just sealed. I can't even imagine what it would be like ported, the words "retarded amounts of output" come to mind. Haibane can shine some light on the subject as well, he as a XXX 15 on an eD nine.1 (~1500x1) and he enjoys it.

[AndonD454]

how is 1500+ watts running on an 80 amp with a stock battery not killing your car? my friends truck with a sotck battery is 80 amps and he cant even turn his volume up with a 1000 watt fosgate amp without it killing it

[sr20de4evr]

oh, and if you're curious, I have some pics of the ZRS-8 (since the pics that are on their site suck)

I would say it's the highest quality amp I've ever owned, but after buying the Linear Power, that would be a lie
