What size amp, alt, number of batteries, etc

[TruckAudioMan 10+ year member]

I want to make a monster SPL truck. I am doing this with, hopefully, 4 15" FI BTL's. I know I need a lot of power. I would like suggestions on good amps to push these with, a good alt and where to get it, and about how many batteries I will need. Other than that, one quick question, would anyone suggest 4 15" BL's instead and why.

For pure SPL I'd stick with the BTLs

So what all power changes would I need to make. Right now everything is stock. I know a little about subs, but as for everything else, I am a huge noob. Help Please.

you're going to want a HO alternator, the biggest one you can afford, want to do the big 3 in at least 1/0awg wiring, may want to change ur batt up front, otherwise get some kinetik HC2400's, depending on ur amps, i'd do like 3, maybe 4 batteries.

i told you in your other post. if you run BTL's, best go ahead an get a 300amp alty. along with i would say 5-10 Kinetic 2400's(depending on what amps you use) or another batt similar to them, an alot of 1/0 wire. for amps, i would go with 2 Hifonics Goliaths, 4 Orion 2500Ds, 4 MA HK4000Ds, 4 IA 40.1's, 4 Memphis 4KWs, the choices are numerous, just research an research to find the best one you think youll like..

remember that in the great 12 challenge, the 12" btl took 9000 watts and kept going. If you want to go big you will need somewhere near 5000 watts+ per sub(only if your looking for records). that is going to require many batteries and a bunch of "HUGE" amplifiers. If it were me I would build an alternator bracket two run multiple alternators.

Research your high output amplifiiers too:

Orion

Hifonics Collosus

RF

IA

Zapco

Crossfire

Kicker

anyone else list some more company's that produce HO amps.
