low cost budget audio

skuller · 01-23-2008, 01:37 PM

I am installing a carputer on my second car
The thing is I want to sell the car in the next 9 months or so.

I would use onboard soundcard (with line out), and factory speaker (4 speakers)
I talked with the crutchfield guy and he said I would burn my speaker immediately if I use aftermarket amp since aftermarket amp give out a lot of power.
I am not going to buy any aftermarket speaker for this car.

everything that I installed on this car would be removed at the time of sale.
So the least the better.

Any idea?
also, the computer would replace the factory hu, so aux in is not an option

thanks

You could get a cheap headunit with AUX in and hide it behind the dash somewhere...

But i don't see why you can't get a small amp and turn the gain down...

I prefer not to buy another small headunit. There isn't a lot of space and I don't like the idea of having a hu.

is there anyone running amp with their stock speaker? I've searched the forum and google, there were bunch of opinions.
Some people said it would be fine, another said it would blow the speaker.

Anyone with the stock speaker setup?

btw. this is for an 06 corolla

that crutchfield guy obviously isn't well informed.

the only reason you would 'burn up' your speakers is if you don't properly adjust your gains for clipping. A small (45w x 4) amplifier would be find on a set of stock speakers....again, only if tuned properly.

nice.
another question
45w x 4 amplifier, is that means 180watt amplifier? where can I get those amplifier?
Most amplifier I saw on audio store rated over 500watt
let me know if you have the brand and model number too

thanks

just do a search for multi channel amps and you'll find the specs.

whats your budget?

I am looking for something below $50
I'd like to keep the whole car pc setup below 600 which mean the amplifier shouldn't be more than $50

I've searched multi channel amps on google but couldn't find anything with low wattage rating.

this is what i've found so far
http://www.onlinecarstereo.com/CarAu...roductID=17594

SoundStorm 4F400
400W 4 Channel MOSFET Amplifier

RMS Power Range : 200 Watts
Number Of Channels: 4
Maximum Power: 400 Watts
Low Frequency response: 12 Hz
High Frequency Response: 22000 Hz
Built In Crossovers: Yes
Channel Separation: Yes

would it blow my factory speaker?

or can I go with a 2 channel amplifier?
something like this

i'd probably mod two sonic impact t-amps 15wrms per chan. and small when taken out of the case.

pokki · 01-23-2008, 06:43 PM

I was going to suggest that as well - they're also handy amps to have lying around.

Felix509 · 01-23-2008, 07:08 PM

You could buy used.... Lots of amps on eBay and on the forums..

For Example:

Clarion 4x40w for $55

skuller · 01-23-2008, 08:35 PM

thanks everyone for the suggestion.

I am just gonna buy the SoundStorm 4F400 from amazon (50 bucks w/ shipping)
I'd like the sonic t-amp but it cost too much (well over 50) and I don't buy used stuff online.

I would definitely write a follow up when everything is installed (give me a couple of weeks)

scott_fx · 01-23-2008, 09:21 PM

wow, they jumped up in price. they used to be 30 bucks.

i'd take a look at these:

wouldn't be a bad option either

skuller · 01-23-2008, 11:23 PM

darn it. Now I am confused again

I just spend almost 600 for everything except the amplifier, still thinking whether it's the right one.

The only way you'll blow your speakers is by playing them to loud. If you set your gains right and listen to the music at the same volume that you used to listen with your old head unit, you will be fine.

I'm using a cheapo $98 Sony Xplode 4 channel amp to power my factory speakers. It's cheap, puts out about 50 watts per channel rms, or 150 watts per channel max (it's labelled "600watts," but the max figures are pretty much useless numbers). It's equal to or slightly better than my stock head unit, which was supposed to be rated at 500w max (rms figures unadvertised because they're probably embarassing).

Just get a cheap aftermarket amp. There's nothing to worry about. And get it from wal-mart, don't get it from crutchfield, especially since you don't care about it. I guarantee a walmart bought sony Xplode will be equal to or better than your standard crappy factory head unit amp.
