APSM-1500 has changed my mind..

Ideally you want the fans blowing over the heatsinks. If you can, somehow mount the fans on the side of the amp blowing at it, instead of blowing up towards the bottom. It can't always be done that way, but it's the best way. But any airflow is better than none.

Agree with you 100%. Air blowing across the heatsink is the way to go. All the parts creating any real heat are fastened to the heatsink. Your amp will be so much happier if you can remove that heat. Any airflow though is better than none.

The BRZ was my 3rd IIRC right after a Kicker ZX750.1. I read online about how "overrated" Kicker was and how Hifonics does "so much better for so much less" and that I'll never run Kicker again after trying "underground" brands. Big fat hunk of BULLSHIT! You're right, that Hifonics does not sound like it puts out nearly what it claims and yes u do have to crank the gain and bass boost to get anything out of it. I replaced my BRZ1200 with a JL 500/1 and the difference was night and day with the same exact setup.
I can honestly say I'd trust an APSM over a BRZ any day. I've actually seen those do work in person.

Did you say Hifoincs was an underground brand????????????

that was what I was told when I first joined the forum and asked about amps.

Exactly. Really the entire amp case is the heatsink, but you need surface area in order to disperse heat. That is why there are so many fins on CPU heatsinks. Wherever you can get air moving across the most amount of surface area is going to exchange the most amount of heat. This is found on the fins that are typically on both sides of the amp, or down the middle as well. The bottom will help, but usually there isn't much heat transfer there as those are thin pieces of metal that don't have much of a coupling to the main case. Really though this time of year you shouldn't have to worry too much about heat as long as you have some type of airflow.

i feel the same way.....i should post a vid. i will wire mine at .25 since im keeping it. looking to pull about 2k off it with 2x rise. we will see

.5 is nothing. but .25 nominal can be a bish. .5 reactive is even worse. we shall see. im lovin it tho for a tiny 100$ test amp

Keyword-tiny.. If that thing can hold up, ESP the new apsm-2000, I can see their sales going up a bit..

i may upload one of my many vids but i need to try and keep this build wrapped up //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif gonna surprise some foos at finals

that would take a while. 1 minute video idk i might try it. or just upload it to youtube on private and release it after finals. ill pm you when its done

Definitely. Cause I'm crashin. But let me know, I'd like to see it. //content.invisioncic.com/y282845/emoticons/thumbsup.gif.3287b36ca96645a13a43aff531f37f02.gif

Yeah I get your CPU heat sink reference. Especially since I overclock gaming PC's as a hobby, and heat along with unstable voltages are my enemies lol.

I'll see how raising the feet up does for cooling. I have a lazer-pointing thermometer I can use as reference for temperatures. It won't be 100% accurate but will help me gauge what helps and what does not cooling wise. Probably just going to use the existing amp screw holes and make a small metal fan frame, screw the fan into place. Have the fan directing air straight down the heat sink.

I want to see this haha.

Could do some simple spacers out of some pipe huh? the diameter of the screw mounting hole, That actually makes it super easy. Could even do it out of some cheap pvc pipe or something..

this...@ 1/4" - 1/2" clearance would be great.
