i'm kinda confused on what amp would be compatible with my factory bose system? please help

 

That box is too small for the sub.

Neither of those amps accept a differential-balanced signal. (What the Bose headunit puts out).

The easiest amp to get your hands on that accepts a differential-balanced signal are JL Audio amps.

 

why does the amp have to accept a differential balanced signal? thats definatly not how i did my amp shopping. im just curious so that i can learn. thats all

 

hmmm anyway i can get away with gettin' somethin' from FRY's? i have a hookup there... so that would be awesome to get somethin' through them. i don't believe they carry JL... and aside from that... JL is usually expensive. unless i go on ebay or CL is it a 1 channel i should be looking for or...?

 

how much is your discount?

 

Because the bose headunit outputs a differential-balanced signal.

Shortest explanation that's understandable - an amp expecting a balanced signal that gets an unbalanced signal sees half of the audio signal as noise, particularly along the lower frequencies (bass) and makes the audio both quiet and degraded.

 

With the budget you seem to have, I can't recommend you installing anything at this point. Keep saving.

 

wow... well the sub is 50 bucks... maybe i should just pick up the sub? and find a used JL amp... ?

 

Dont buy that sub

Get this

50 dollars cheaper than the one @ fry's

 

well the one that i showed is actually 50 bucks... so it's 30 bucks cheaper than the polk audio... but i don't understand how i have to run a JL amp... tons of people are running other amps on this board... is it because they don't have bose or what?

 

you dont have to use JL. You can use which ever one you want.. I would recommend a Class D amp if your just using it for a sub. All you have to do then is find your bose harness, tap the front left and right speakers (+ and -) prior to entering the stock amp. Those will go into a LOC (line out converter/ high-low) which convert the stock signal to RCA (right and left balanced output) which go into the amp and badabing badaboom..

 

Just save up money and buy a better sound system. All that stuff you plan to buy from fry's is going to be worthless. Probably won't even sound good or barely make a difference than your stock sounds now.

 

And badabing you're trying to send a differential-balanced signal to an amp that's not made for it. Good luck with sound quality on that. LOC isn't a balanced signal converter.

You don't have to use JL Audio, there's a few others that take differential-balanced signals, but all JL Audio amps do.

 

ok thanks y'all. im gunna shop for a used jl amp
