jl 500 substitute

instead of getting another jl 500 to run my 10s. i was thinking about getting a Hifonics BX605. 600 rms at 1 ohm, would be perfect for my w3s . . or would going fron jl to hifonics be like suicide?

My opinion. The JL is a better amp, but if the hifonics will do what you need why not?

if i have 8-volt preouts, with a cap, the hifonics should get 14.4v right?

Pre out voltage has nothing to do with how many volts your amp has to run off of.

A cap doesn't add voltage to the system. If anything it adds another item your alternator has to power.

If your woried about power, go with the JL.

if i can save 400 bucks and get the same amount of watts i would love to do so. but dont most website rate their amps at 14.4v, and stock batteries and alts usually dont put out 14.4v right? so i really wouldnt be getting the rated watts from the hifonics right?

Batteries are 12 volts, alts run higher so they can charge the battery, and power the rest of the car.

Yes alts do tend to run at 14 volts, but if you pull more amps than it an alternator can handle the voltage will drop considerably.

Like I said. If your worried about power go with the JL.

I think I understand this business about better amps lasting longer. But if it is the case as I saw in another thread that your subs are gonna sound the same with similar power, why fork over all that extra money?

The Kicker, MTX, Soundstream, PG, or the HiFonics will still last a heck of a long time. As far as power goes, you can get a 'higher watt' amp and still come out much more cheaper than a JL.

The only other thing I can think of is the stability of the amp at lower ohmage....

JL Amps are also rated to put out power from 1.5-4 ohms @ 11-14.5v.(looking at the 500/1)

yeah thats what i was saying. since i have 2 amps with stock electrical system i know the hifonics wont have 14.4v so i wont be getting 600 rms. and thats what i need

Are the w3's rated at 300rms?? If so why not just stay with the JL you have now? Going from a 500 watt amp to a 600 watt amp, you wont hear a diff at all. Or are you wanting to put one amp to each sub?
