750-1000W at 4 OHM Suggestion

[jda 10+ year member]

I have several 1500-1bdcps and they are fine... but I wanted to try something else.

Needs to be D class, efficient and quality.

Cost is not really a big deal - under $1000, or so.

Any suggestions? The 1500-1bdcps are about $425 and seem like a good deal... so even you think that I should just get another one of those, then that is OK too.

TIA

for that kind of money you shouldn't have a problem finding one. Maybe look into the Alpine PDX series amps

Holy crap. Why limit yourself to 4 ohms? Quarter of the cost and you can easily achieve that at 2 ohms. I guess people have money to blow in an inefficient way I suppose

Sundown SAZ-4500D - 900@4ohms? probably closer to 1000+

4 ohms means less heat, less input requirement and significantly less distortion. I want to be in that .01 thd range even at 1000W. I can also keep my electrical system totally stock even at super high volumes.

The only downside is amp size and cost. I can handle both of those to not sacrifice in other areas.

I have my eye on an Audison Uno and even another 1500bdcp. I have a ZX2500, but that thing is HUGE and I am not sold that it is all that clean.

You're not going to hear an audible distortion at that low of a frequency coming from your subs and amp anyway.

I have a stock electrical system with 2 amps. Both at 2 ohms and a total of 2200 watts

distortion dosent always equate. class d amps square off the signal.

You can hear it.

I have a 800a2 and MTX 2300, but they sound plenty muddy bridged over 50. They also really eat up the juice. In all fairness, they could be half worn out.

What do any of you care what I spend my money on? After I bought the No. 7s, this is all cheap stuff.

 

[Trancer 10+ year member]

Cause your purpose and meaning behind what you are doing isnt exactly correct as just figured out.... Do what you want I guess.

Weird that your 800a2 sounds "muddy." Sounds more like a sub issue. 800a2's have a full Mosfet PS if I remember correctly, and do well over their rated power.

 

[jda 10+ year member]

I will. It works for me. I just wanted to know if anybody had any suggestions about a D class 750-1000w amps at 4 ohms. I am considering something new - I am dogmatic enough with my subs and components. I don't really care for any help on my methodology.

My thanks to those who had some suggestions.
