What ohm-age are the Infinity speakers? 4 ohm?

Are you looking to buy a new amp, or would you consider a reliable used one?

 

I wouldn't worry about a high output alt, just a good quality battery, Odyssey, diehard platinum, ect..

 

What's your budget?

 

They are 4ohm

Maybe a used. Alot of the new stuff is crap unless you go high end audiophile.

 

I'd suggest a good used old school 4X50W or 2X50W amp. With any luck daveds50 will show up with some recommendations (or maybe even some offers).

Otherwise, take a trip over to DIYMobileAudio and browse some of the 'what is your favorite...' threads to gather some recommended brands and models.

 

try to find an ADS PQ10, good amp, i wouldnt worry about batteries or alternators for that small of an amp...

i have two amps with the stock electrical system and its fine, sure i could get some more out of it, but meh, for the price of the electrical system, ill just stick with what i got:waytogo:

 

go on to ebay and search for an ebay store called "audio clinic"

He refurbs US Acoustic amps... they are inexpensive, solid and have great SQ - the "USB 4060" will be perfect for you.

 

Couldnt find that store.

I think the general concensus is to just use the fronts???

 

I just put in a JL 300/4 in mine and it kicks ass on some 6 1/2 components, gonna bridge the other 2 channels for a sub. My brother is also a big fan of Elemental Designs, that is all he is running at the moment. Their stuff sounds good, he was an installer for about 10 years too.

 

Have you looked at Sundown Audio? They have a 50W(RMS) by 4Ch at 4ohms for sale in this thread http://www.soundsolutionsaudio.com/forum/index.php?/topic/32442-sax-50-4-close-out-continued/ Granted the amp has been discontinued but if you purchase from them, they use paypal, they will still offer a two year warranty on it.

You can find more detailed information about the amplifier at this link http://www.sundownaudio.com/index.php/products/discontinued/sax-504.html

And no, I have no affiliation with Audio Clinic at all. I have heard and seen the gear he sells though and if I could manage to sell the eD Nine.2's that I have ($150.00 each or $250.00 for the pair), I would be running the US Acoustics stuff.

 

US Acoustics.. LOL setting your standards low I see..
You'll be lucky to get a year out of that cheap crap.

 

The USB series US Acoustics are actually USX amps - Hardly "cheap crap". These are significantly better than the Chinese crap being put out by a majority of amp makers today. Like I said, from my personal experience with them.

But again... dont take MY word for it: Here is a decent list of amp rankings - take a look under "Good Quality Amps"

They arent the Zed-Made USA series - but I suppose you figure those were cheap pieces of crap too...

However since they are ranked pretty solidly among amps like the Sundowns, JL Slash's, Treo's and the Phoenix Gold Xenon series amps, and I wouldnt qualify any of those amps as "cheap crap" - I think I am safe in recommending that anyone short of a hardcore SQ whore would be more than happy with the solid performance, low noise floor and longevity of the USB/USX series of US Acoustics amps.

 

I know all about the USX amps and yes, they are still made in China..
they are assembled in the USA..
Like I said, You'll be lucky to get a year out of it..

their ratings aren't for long term use..
cheap crap as in cheaply made, nothing to do with price..
Once a brand gets built up by a good rep, thats when they
get cheap and have it made overseas.. Just look at Alpine..
USX AMps...you should buy it..

 

Sorry, the USB/USX amps (not the blue-bar versions) arent made in china, they are made in Korea - might not seem like much of a difference, but it is huge in terms of quality. Of the USB/USX amps that I have personally heard and seen, they are all working perfectly... a couple of them are well over a year old and others are well under, having just recently been installed.

If you need it to be 100% made in america... good luck, there are very few. I think the list starts with Tru and ends with Zed - and I could be wrong, but I think thats the whole of the list.

Either way... if you have the choice in buying an Alpine, JL, Etc... or a US Acoustics - you could spend the 300.00 or more on a Chinese made JL or 80.00 on a Korean made US Acoustics... Or, the 600.00 on a Zed/Tru and never be able to tell the difference in sound or "quality" of build.

 

I'd just go the route of having my older classic amps rebuilt by Dave..
No need to convince me, by all means, spend your money on what you feel you should..
more power to ya..

 

Korea, yes... so are Boss, Crunch, etc. i would not say Korea is better at all, although there are a few acceptable amps that come from there.

you may be impressed with Zed, but i am not. i have a personal story that would blow your mind.

besides, there are Zed designed amps that i would rate in the POS category...

amplifier design is not rocket science. in fact, it is the easier pieces to engineer in car audio.

I'd just go the route of having my older classic amps rebuilt by Dave..

that has been keeping me very busy lately. there are very few amps these days that will compare to the "old school" in both sound and build quality.

dave

 

reminds me of tube stereo's.. IMHO nothing beats em for sound, depth and warmth..

 

agreed, along with the rebuilding of older amps. I think I still have some old school zapco amps in my attic some where when they made quality before selling out. But in my experiences people are like herds of cattle and can be swayed to go where ever very easily. LOL just my 2cents

 

Can't go wrong with Arc Audio. Besides them there are only a handful of amps I'd want like Zapco Competition, JBL Crown, Cadence Competition, and Audison.
