do u realize ur alternator does around 13.8v at idle , so its gonna be really hard to see those numbers.

Also i bet that amp is really overrated, have u bought the amp yet???

Your alternator DOES do about 13.8 volts. That amp is overrated. It most likely puts out closer to 600 watts at 1 ohm. Not 900. What is your budget on the subs?

Almost all stock alts put out around 13.6-13.8 volts.
For a single 15" - http://www.ascendantaudio.com/havoc_page.html
For 2 12" - http://www.ascendantaudio.com/arsenal12specs.html

The single 15 can handle 1500 rms.
The 2 12"s can handle 1500 rms(750 apiece)
2 12"s for 440
single 15 for 425
And eventually you can get a better amp to really give them some power.

Well he said 400 - 450 and those are my suggestions for that price range. An l7 or a pair of cvr's would probaly serve him better but thats only around 200-300 dollars.

yea, but if you offer subs that have 1500 RMS, and he'll be pushing out around 800 RMS because its "900RMS @ 1 ohm at 14 Volts" he'll be underpowering them and it might sound good but it wouldn't be that loud? right?

400 bucks a pair of M3 12's gotta find a memphis dealer or you could use www.woofersetc.com, go to memphis there in the 200 dollar range

thx guys, i was looking in to the havoc, but i was afraid i might underpower it so much that it wont be too loud?? but i dont know too much about this stuff so do you think that the havoc on that amp would get the job done, because eventually i will get a better amp

Just because a sub is rated at 1500rms doesnt mean that it won't be loud at 800 rms. And in the future he can eventually get a bigger amp and won't have to worry about having to get new subs. Its just a suggestion. A 12 inch XX.X at 300 watts rms will play about as loud as a kicker cvr at the same wattage level. Even to the XX.x Can handle 1600 rms. It might be a waste, but it could also save him money in the future.

Yes, The havoc will def. get the job done on that amp ( as long as you don't clip the amp) and you won't have to replace your subs if you buy a more powerful amp.

A single 15inch havoc will destroy a pair of m3's in spl. And still sound good doing it. If you were to purchase the M3's, you could not get a bigger amp unless you also upgraded your subs. For 25$ more the havoc is a better deal. IMO

you could always use that 400-450 to get a nice sub and upgrade your amp if you wanted, ans sell the one you have for more $$

Memphis makes some very nice equipment. But for the price the Havoc is a better deal. Both companies have good build quality. Those M3's handle 300 watts apiece. The Havoc handles 1500 watts. I would go for the Havoc due to the fact that you are looking for spl.

theres a killer setup. then sell your amp for $50.

orrrrrrrr... get the havoc... dont install it, and save up about 400$ and get an amp that can power it.

He could hook it up to the visonik as long as he is careful with the gains.(clipping will destroy a sub.)

but i havent heard much about this crystal comp brand or what brand of sub u linked, are they good as treo or better and what about ascendant audio, how do they compare

clipping is when a signal, which looks like a wave, is amplified so that the top and bottom are cut off, or "clipped" off, so the signal is no longer clear. this will cause extra heat on the VCs and will blow your sub. by turning the gains up too much or turning the volume up too much on your Hu you can clip a signal. and as far as crystal.... great sub, chauncy has heard them and is in love with them. ive only read reviews and have yet to read a bad one. if you can get a Treo TSX 15 that would be great too. ... and your not going to get 350 for that amp... sorry.

Clipping is when your amp tries to put out more power it acttually can. This creates a square sine wave.

What trevor said. Crystal and Ascendant are to great companies, but I wouldn't compare them to Treo. The TSX or the havoc are your two best bets IMO. And you def. won't get any where neat 350 for that amp. Maybe 200 if you ebay it. probally closer to 100.

nick- are you saying crystal and ascendant arent up to Treos level? dollar for dollar i think they are... but of course Treo has super subs that handle TONS of power... they are also a fortune though..

If you hear distortion from your sub. Turn it down. Set the gains to the output voltage on your HU. And don't turn the bass boost up all the way.

IMO Crystal and Ascendant are very close to, but not quite equal to the build quality of treo drivers. Treo drivers are VERY underated.
