Is this to much power?????

[revrider1 5,000+ posts]

I have an amp rated at 1500w at 1ohm. I wanted to know if you'll thought it would be to much power for 3 10" Alpine Type E subs in parallel, which would be about 500watts each. They are rated at 250rms and 750peak.

What amp?

Nothing fancy just a Lanzar 1500d .

First off that 1500 @ 1ohm is MAX rating. Not RMS. Id be surprised if you pulled anywhere near 1KWRMS.

SPECS

1 x 400 Watts RMS at 4 Ohms

1 x 800 Watts Max at 2 Ohms

1 x 1500 Watts Max at 1 Ohms

Mono Block Subwoofer Amplifier

1 Ohm Stereo Stable

MOSEFT Power Supply

PMW (pulse-Width-Modulation) System

Glass Epoxy PCB

Custom Terminal Block for Speaker Connection

Thermal, Overload & Short Protection

Variable Subsonic Filter (15Hz-50Hz, 24dB/Octave)

Variable Lowpass Filter (50Hz-250Hz, 24dB/Octave)

Remote Bass Control

Input Impedance: 10k Ohms

VU Meter

Thermometer

Heavy Duty Power Coated Heatsink

Frequency Response: 15 Hz-35 kHz

S/N Ratio: 90 dB

Dimensions: 10.95''W x 2.3''H x 15''L

got that right from Lanzar's site cuz I dont look at Lanzar so didnt no right off hand...

so no thats not too much power //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif keep gains down...tho..

I figured that it would be ok just wanted some opinions, I just got a good deal on this amp considering I really needed a 1ohm stable amp since I blew mine . They sounded good, I was giving them 800watts.

On the inside I think the 1500D is a 1200D - that's about 400w a piece at full bore.

Be cautious with the gain settings and easy on the volume knob. You could roast them if you wanted to, but if you use a little common sense they should run fine.

Just so you know, in a parallel circuit, all loads (speakers) recieve the SAME voltage/wattage, so if an amp makes 500w rms into 2ohms, all speakers in that 2ohm loaded channel will recieve 500w. If they are in SERIES, the wattage is divided among the loads according to their resistance. To sum up, speakers in parallel do not "use up" the watts they need and pass the rest on, that is a series circuit. Thought I would clear that up.

I hooked it up, and it sounds great. I had an audiobahn amp running them before //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif , but as we all know Audiobahn isnt worth the crap . I fried the Audiobahn amp, and to de honest as cheap as Lanzar is they sound better with this amp. I am just tryind to get full sound in my work car . I know about audio equipment, my show car has all old skool US Amps and old skool Orion Subs //content.invisioncic.com/y282845/emoticons/bowdown.gif.b85b23b82970bd22fb6b549c3392f016.gif .

so you had a 1500w audiobahn amp and fried it huh?

 

[Denial]

Lol....

IMO Audiobahn>Lanzar

Uh, no.

Current is = at all points in a series circuit. Voltage is = in parallel. In neither case is the power to all loads in the circuit equal to power at the source.

Following your logic - if you wired up 8 8 ohm subs to a 1000 watt 1 ohm amp each sub would see 1000w. If that were true every bass head out there would be doing it, not to mention - all the worlds energy problems would be erased.
