In need of a amp for my boat to power 4 tower speakers at 250wrms. something that can be ran hard and long with out over heating. I live in AZ so the summers get pretty hott. I'm only running one pair now but I want the headroom for a second pair.

If you want to go cheaper you can bridge two smaller 4 channels to a pair of speakers.

Well ****, I apologize, linked up a subamp that was copied for another thread. Meant to link up a cheaper than normal price for the one Ram recommended. And as Bassin said the lightbox runs hot. The arc ks125.4 does as well, that is assuming bridged 4 ohm on both amps.

is that sundown full range? also how bout running two vibe litebox4 amps? they seem to be a arc ks125.4 clone.

the lightboxs run hot as hell. i just returned one for my uncle. running 4 ohm 2 channel it was too hot to touch within 10 minutes of high volume.

That sundown looks huge! how big is it? I can't seem to find dimensions. I might not have the room for it. Also what does it do bridged at 2ohm. I'm guessing that's how your suggesting I run it?

alright found my answers. dimensions are 30.75 x 9 x 2 and output is 800x2 at 2ohms bridged. This would definitely do the job but is too big. Also running 2ohms bridged seems like it would get real hot? I'm going to double check if I have room when I get home but I don't think I do.

why would you try an bridge it? you have 4 speakers that are 250rms, you just run the sundown only to them all. what speakers are they @ 250rms?

 

[jackclove 10+ year member]

the sundown only does 200rms x 4 at 4ohm I'm looking for 250. The speakers are HLCD bullet hollowpoints.

50 watts will not be discernible to the ear. That would be .6 db increase for 50 watts. 1 db or less is considered inaudible. Also the sundown will do over the rated rms. So it would not be a true 50 watt difference in what you want. Not trying to sell you on one. I can care less. Just referring back to the original concern of high heat environment. I don't know any others that run as cool.

I saw that Zed audio amp. It's a beauty. Just may have to wait for it. Also the sundown is to big it won't fit where I want to put it. It ***** there not going to make the Kronos anymore though
