Car Forum / Driving, Maintenance, Tuning / Car Audio / March 2004Pic of inside of Lightning Audio amplifier
You may remember a week ago or so I posted a pic of the inside of a Radio Shack amp I bought. You could tell it was almost worthless. Here is a pic of the inside of my new Lightning Audio amp, for those who are interested in such things. http://myweb.cableone.net/zirconx/LA-amp.jpg Looks much better, I think. The pic of the Optimus amp is still at: http://myweb.cableone.net/zirconx/amp1-low.jpg -Ryan I'm not interested in owing an Optimus amplifier (although I used to when I was a teenager working at Radio Shack), but I am curious to know what relevance the inside of an amplifer LOOKS like in relation to its sound. Tony  SignatureWhat's more likely? That an all-powerful mysterious god created the universe and then decided not to give any proof of his existence? Or, that he simply doesn't exist at all? And that we created him so that we wouldn't have to feel so small and alone. -Eleanor Arroway, Contact > You may remember a week ago or so I posted a pic of the inside of a > Radio Shack amp I bought.

Well I think you can tell a lot. From the pic of the optimus amp you can tell that it's basically the same type of amp that is in a head unit. So it is basically worthless if your headunit has speaker outputs. Also someone posted this URL in a reply to that thread http://arawndark.netfirms.com/AMP450/index.htm, showing the internals of that amp only taking up a little more than half of the size of the actual case (deception my the manufacturer). Also I've read in this group that people have opened up amplifiers and found sheets of lead put in there to make the amp heavier, implying a more quality unit. Also you can see the size of the power supply components, and how well the transistors are heat sinked (lacking in either of these areas are indications that amp is probably overrated in power). I've also read, in this group, people taking their amps apart and seeing poor construction, with solder joints that are coming a part, etc. So to answer your question, I think you can tell a lot by looking at the inside of the amp. > My thoughts exactly, this guy keeps posting pictures of the inside of amps, > maybe he should go hook them up and listen to them. Actually by opening up the optimus amp I was able to tell that it was not even worth hooking up, it would probably sound the same or worse than my head unit. I will definately be hooking up the lightning audio amplifier. I especially wanted to post a pic of the L.A. amp because many people are interested in this brand of amplifiers, but there is not a lot of info out there for people trying to find out if they are good or not. So there's a pic, see for yourself. The board takes up the whole case, the amp uses real transistors (not ICs like the optimus), it is well heat sinked, and there a no fake weights in it. And after I get it hooked up I plan to post again with my impressions about how it sounds, if it thumps when it turns on and off (I understand this can vary by installation), etc. And just another FYI, the Optimus claims to be 25 watts a channel, it has a 7.5 amp fuse. The Lighting Audio claims to be 50 watts a channel, it has a 25 amp fuse. -Ryan Nothing really IMHO... but it can be used to determine which amps share the same PC board. for example Lanzar 1200D = Boss R3000D = Tsunami 1000.1 = Pyramid 2400D. All 3 amps are internally identical, but are priced differently, and they have different RMS wattage specs. I like the Tsunami the best of them all, its reted the most conservatively while the Pyramid 2400D has the most heatsink fin surface area and should in theory dissipate heat better. Ive seen the tsunami and pyramid sell for $120 while the Lanzar 1200D is $200 - 250. You can really save a lot of $$$ with this information. The 1000 watt mono Clarion APX series amp (the black one) share the same PCB as a high $$$ Arc audio. Manufacturers hate it when we find out these kinds things. Theres a post pics inside your amps thread on termpro for those who care.

What about brands like THUMP and PYLE and MOBILE AUTHORITY are they identical to any "good" brands? Because there is a luquidation store here that sells them for DIRT DIRT DIRT cheap. >Nothing really IMHO... but it can be used to determine which amps share >the same PC board. for example Lanzar 1200D = Boss R3000D = Tsunami [quoted text clipped - 23 lines] >> >> Yes that 2400D is a solid amp. A kid across the street has one in a chevy corvair with a pair of RE 12s... dam that thing is LOUD!!! Generally I am a pyramid basher too, and wouldn't be caught dead with one of their amps in my car. But at the same time I can regognize a solid piece of gear, and I'm saying this is a solid amp for the $$$ IMHO. He got it used on ebay for $125. Sorry I have no first hand experience with thoese other brands. Garrett >So are you saying... that there is a pyrmiad amp that is "good" ??? > [quoted text clipped - 36 lines] > > |
