Amp and Sub ?'s

[95_indiblue_sho]

I was curious, would it be possible to remove the factory subwoofer amp in a Gen II with the factory JBL Premium sound system and connect the wires that are already there to an amp and then to a sub. Wow, that was long. I would like to leave the other amp alone for the regular speakers but replace the subwoofer amp and subwoofer.

I'm looking into some type of bandpass box with an amp with it. I would like to set that up in the trunk with as little work possible with the wires.

Any suggestions would be appreciated.

Your new subwoofer and amp setup will require a bigger size wire depending on the amount of power it's pushing. You will be starving your amp if you use thin wires. Purchase the correct amp wiring kit and get professional installation if necessary.

that's kinda what I thought.

Oh well, what needs to be done will be done. I think my dad could help me with the wiring part of the job.

Now it's up to me to get the money frown

It is quite easy to run new wiring just have to remove some panels. Will you be using the stock head unit? If so I would not recomend it as it will not prodce the best quality sound. It can be done though. I would recomend a sealed box as you can get a lot of bass out of a sealed box.

I always thought a properly vented box would create a better bass sound. shrug . I thought that created a better resonance sound that goes throughout the car

BTW, I would probably initially have the stock head unit, but later get a better one when more money is available.

I would get a head unit first as that will be the key to a great stereo system. Also you will have to redo wiring if go with the stock head unit. Also the head unit will provide a better sound as well. Also to properly do an amp, subs and wiring will get to be a good amount. My wiring kit (powers 2 amps) cost me $100, then the RCAs which where good ones $50(4 Channel), the subs were $100 each (2 MTX 6000 series), 800watt mtx amp $150 (it was on special) and the box was custom made for $125. So get the head unit first it would be good to start there.

A seal box produces very good bass. I can feel mine up to the front seat and I can be heard for blocks if it is up. Sealed boxes tend to be used for competion as well.

You're definitely going to want thicker gauge wires if you're going to be running an aftermarket sub. It's not too hard to run a new wire though. Using the largest possible gauge wire that the amp will accept is the best way to avoid headlight dimming and other electrical issues when the bass is turned up.

I would suggest getting a low end amp and sub (maybe a 10"?) and a box as opposed to a powered setup. Sealed boxes have distinct sound quality advantages, and anything is better than a bandpass setup. The only powered system that I've heard with half decent quality is the Infinity Basslink, which can cost a bit of money. The 'bass tubes' like the Bazookas tend to be tuned a bit too high to offer good low frequency extension.

actually they normally use ported enclosures tuned to a certain frequency for competitions unless you are speaking of SQ competitions.

if your just wanting a little extra bass then just adding a amp and sub may not be a bad idea. you can you use high level inputs on your amp which are usually spliced into the signal of your rear speakers. and definately run new wire to the new amp. but if you try to go with some major bass the stock system will be totally drown out at high volume.

want a good box idea.... talk to the guys at BOSE, but any way... if you are going to use the factory setup... as I am... you will be needing to use the signal from the speakers for your subwoofers ( or other speakers being used through the aftermarket amp ) you will need a line output controler. I bought one from Best Buy for i think it was 10 bucks. Seeing that if you are using this for subwoofer.... quality isn't going to be a major issue, the very low frequencies are very hard to distinguish for "clarity" really, just just for more bass.

Well unless you are competing... go with a new head unit, but i'm just adding some 15"s naughty for some extra bass. (these arent very good ones if you ask... thump brand. ) I got the pair for like 30 bucks.... and i'm powering them with my jensen 200 watt... so it's bass...

But anyways go with the line controller.

If you can get an amp with speaker level inputs, you're laughing. Line level converters that you get at Best Buy or Walmart normally generate a little bit of line noise, unless you go to a stereo shop and drop about $40 for the Alpine one (totally worth it, if that's the way you have to go, IMO).

Here would be my suggestion if you want something cheap:

Profile amp 100x2, 300x1 bridged RMS $73
http://www.ikesound.com/product-product_id/1179

That'll provide adequate power, probably not as much as it says, considering it's a Profile, but it'll do okay.

Pioneer TS-W305C 4 ohm sub $49
http://www.ikesound.com/product-product_id/1171

Then just grab a little box for the sub and you've got some decent bass for around $150 altogether. This will hit and shake your car nicely, and sound quality won't be too bad.

Us Acoustics brand amps have speaker level inputs, i had them for sometime...and they are easily as good as profile...

but that amp and sub combo would work fine for alittle added bump for someone on a budget. that amp or the US Acoustic USX2100 amp, read some reviews about it, they are really good for their low price.

If you can find a US Acoustics amp for a decent price, go with it. They are fairly decent as well. A friend of mine has one, and it's held up great, I don't know anyone with a Profile amp though.

umm ya in a SPL comp arena 99% of vechiles will be vented... Ill post a link to a car i just finished for a customer its soo loud it rattles the rust from his car.... Latest car pics

 

[shoRunner]

hey steeda, i see you have the Clifford 2.5 in your car. i just ordered this for my car, and was wondering if you could tell me how you like it. did you add on any extra sensors?

 

[SteedaSVT]

i have prox(motion), mini pizo siren, battery backup, and 2 merc switches...... its a great alarm i install them all the time

I posted this in another topic also, the jbl amps have an electronic high pass crossover inside them, if you used the speaker wires for the rear speakers as inputs to your amp, you'd only be getting 170 hz and above to your sub amp, you will have NO BASS no matter what kind of box you have.
