Definitely a "supposedly". Actual power output probably isn't even 250rms x 2....prolly more in the realm of 125rms x 2 or so....very cheaply built, unreliable amps. This is presented just as information, NOT criticism. peace

Looks like a good install to me... almost exactly the same as mine. My amp's about the same quality level too . Are you going to get a sub to go with it? Or is it just going to power the 6x9s? Oh, and what car is this going in? I didn't see a full picture of it.

Its already IN a car. my 1987 Oldmobile 98 regency Brougham. not much but its my car, once i pay my parents back. and its jsut powering 6x9s, but not those, a pair of audiobahns that will be in next 2sday.

this was basically me hating stock sound, i wanted something better, this isnt much better but it is an upgrade.
im looking at getting REXXX12s [which i know about thx to you all] this summer, maybe atlas 12s. not sure what amp but ill make a thread about it when i get the money.

P.S. i dont mind criticism as long as its constructive

That's a good first car. I'm sure you'll take good care of it

I hate it when kids get BMWs and M-Benzs for their 16th birthdays from their rich daddies. No offence if that's any of you out there. I've earned everything I've ever owned, and gifts that are worth more than the tuition of the college they're going to are rediculous. Ok, ranting done for today

So what companies make good, reliable, low distortion, non subwoofer amps with deecent power for cheep? (affordable amp for me would be under $150)

[Diceman83]

by non subwoofer, do you mean dual or quad channel?

I'm wondering too... I'd like to find a new sub amp and a 2 or 4 channel for my speakers.

[Thourun]

Anything meant to power the regular speakers, like ant speaker under 8", but why not include subs as a seperate catagory.. What are good brands for both?

[CBFryman]

look at Profile (ask nsgm13) and Pheonix Gold (from personal experence, great, reliable amps), check e-bay for good prices on both for slighly more you can buy from an authroized dealer.

[Diceman83]

You seem to think that amps can only do speakers or subs, but not both...

The only amps that are designed specifically for subs are the single channel "mono-block" amps, and are generally $200+ for the cheap ones.

The 2-channel and 4-channel amps that you see everywhere can almost always be bridged for single channel use with their built in low pass filter (blocks all frequencies above a given value), used with just midrange speakers with the highpass filter (blocks all frequencies below a given value), or used with both when set in full range with a passive crossover (this is called Tri-mode Operation, and you use a high pass filter on the speakers and a low pass filter on the sub to keep the appropriate frequencies going to the different speakers). In your searchs, remember to look just at the RMS power ratings, not the "max" values. You also want to try to match the sub's RMS rating with the amp's, or get an amp that's MORE powerful than the sub. This is a good rule of thumb for someone beginning in this hobby.

The audiophiles at the 3000GT board I also frequent said that the profile amps aren't great quality even at the cheep prices they go for, they look like great cheep amps to me but they reccomemded a soundstream picasso, any thoughts?

The THD of the Profile 440 is .07% @RMS and the THD of Soundstream is .02% @RMS, what exactally does this mean?

[CBFryman]

THD is total harmonic distortion. i dont know about profile so ask NSGM13.
basically a THD rating below 3% is almost impossible to detect when playing music and barely able to be detected when played with tones....even 6% is hard to pick up wiht music...

[CBFryman]

oh and jsut because an amp doesnt have fancy plastic over its heat sink or lights inside the heat sink or w/e doesnt mean it is cheap...

[Thourun]

So is an amp an amp or do different amps make things sound different in ways besides the obvious amplatude factor?

[L|_|da]

some cheap amps will make things sound flat, my friend pick up some off brand amp on ebay, it boasted a 500W rms, 2ch. thing barly works, and over heats like a bitch, and sounds horrible. it was shipped in an audiobahn box, its really sad. atleast mine came with a manual.

get something good, you wont regret it. a lil more investment into you intiail amp purchase will avoid having to spend more money on one later, like im going to have to.
