i want to upgrade my amp, which is better for spl the rockford 4000bd or the spl dynamics d5 they both put out more than 4000 rms at 14.4 v

the SPL DYNAMICS D5 i have one in my car an believe me it does wuk and the amp can work at much higher voltages than 14.4V if u want more info on the amp call 7637525 ask for heulan he is the dealer for spl dynamics in trinidad

spl dynamics is the way to go. They have the same board as the america bass 500.1. This amp will do way more that what it states it will do.

1 x 1400W @ 4 ohms (14.4V - 1% THD)
1 x 2650W @ 2 ohms (14.4V - 1% THD)
1 x 3200W @ 1 ohm (12V - 1% THD)
1 x 4700W @ 1 ohm (14.4V - 1% THD)
1 x 5600W @ 1 ohm (16V - 1% THD)
1 x 7100W @ 1 ohm (18V - 1% THD)

If you train your battery(mine sits @15.5volts) you will get a shitload of powa. I get 5350rms off of one of my america bass 500.1amps. That's with 5runs of 1/0+ and 5 runs of 1/0- welding cable. The worst thing is I still need to add another 10 runs of 1/0 due to the fact that I'm gettin really bad voltage drop. I know what you're gonna say,"upgrade my alternator" but it doesn't matter cause in db drag street classes you're not allowed to have you car running. But don't worry when I move down to TT I'll be bringing my 750 amp alternator with an external regulator switch to either turn up or down down the charging on the alternator. :wink:

i Find that very Hard to believe you are seeing that sort of power in car, On a bench probably but not incar,

Did you clamp it,Lets see your Voltage Numbers,
I'll Love you see your Rise.

my rise was from .375 to 10.34ohms.voltage dropped from 15.5 to 10.5off of a fluke multimeter. We don't use regular batteries up in north america. I use a DD battery. Check the DD website for the battery. And no that is not a bench test. Ooops my bad I got 4350rms off the 1 american bass 500.1. My battery sits @ 15.5volts. You have to train the battery bro in order for it to sit that high.

Training batteries really Shortens the battery's lifespan drastically, Its not practiced here locally because of the price of good batteries,

I know of the DD battery, its basically a Batcap 8400, with a DD price Tag.

I was refering to the Output figures in your test , AC Voltage and Amps and also the current draw during the test.

US$1200 for a battery is crazy

Lance · Postby **Lance** » October 4th, 2007, 9:12 am

People In street Classes(A&B) have no problem paying that, They are limited to 1 battery up front and vehicle must be off when burping, they try to squeeze 10kw worth of power out of 1 battery.

You could get 8400's for much less than that.

The Cactus Sounds battery is About the same price.

People making the switch reported around a .5db gain though.
