1st you will be very upset with the low quality of the crap subs you got, as for an amp you should look at your rms watts(380 each) and get an amp with an rms watt about 50 rms over the speakers(800 would be great at 4 ohms) but again it is going to sound like crap, if i were you i would return them and get something better.

He didnt ask if we thought his new subs were good, he wanted to know what kind of amp he should run. Not everyone wants super loud speakers they can turn all the way up and blow the windows out with. Maybe he just wants a little more bass and doesnt care too much about getting super high quality subs. Leave his purchase alone. Still, as you said, an 800 watt amp should power them well.

unfortunately Jma20a is right. those subs are a waste of your time. Sony in general is a waste of time, and their car audio stuff is no exception.
ideally, you would want to match RMS power exactly on speaker and amp, but for these subs, as Jma said, i'd look for an amp with enough power for 400w RMS for each speaker. a mono-block amp will be the best way to go as the power is generally cleaner and much more true; however, you can run a 2 channel in bridged mode to accomplish the samething and probably a bit cheaper as mono-block amps are pricey.

X2 He is only making a question about amps.
and also I Had sony head units in my last 2 cars and no problems at all.
He is asking for help.
Enstead of give him crap why you dont give him a good advise on what kind of amps he needs to choose.

edit: i also should've kept my opionions to myself because it strays from the info the OP is after.

you need an 800watt rms monoblock amp. car audio rule #1 - never go by the "max" or "peak" power rating. it's all about the "RMS" or "Continuous" power rating. you will follow this wiring diagram:




a bridged 2 channel amp will not work. if someone made a 2 channel powerful enough, you could run each sub off each channel, but i am not aware of a 2channel that has 400w rms per channel.
you can also bridge a 4 channel and run each sub off of each of the bridged channels.



as far as actual amp suggestions.....

you could run this amp (if you like sony products), but it will way overpower the subs
http://www.bestbuy.com/site/olspage....=1149205463777

same story as above with this Kenwood:
http://www.crutchfield.com/S-Vmg4GvN...0&I=113KAC9103

this alpine would be a great match, although you would end up with an amp that is kinda out of the sub's league. and by that i just mean that a really nice amp with sub-par (doesn't matter what brand they are) subs. kinda like putting honda civic quality parts on a ferrari:
http://www.bestbuy.com/site/olspage....=1166840026929

this kicker would also be a great choice, but like the alpine above, it's just kinda out of the sony subs league:
http://www.circuitcity.com/ssm/Kicke...oductDetail.do

this MTX is also in there with the Alpine and Kicker:

if some one is buying 2 12 inch 380 watt rms subs, is looking to have a little bass!!

if someone wanted a little bass they would most likely go with a bazooka tube. it adds a little bass to even out a stereo, and takes up far less room than 2 12"s.

teal. the amps that TXST suggested are good choices. kennwood, alpine, mtx and kicker will work great with almost any sub.

check out crutchfield have way more than enough info on all of the products they sell.

if you get high powered 10" sub with a good quality amp you should be set. audiobahn has some nice subs along with mtx. if you can afford it go with memphis audio. i put in a 10" audiobahn sub and a matching amp.

NO! Keep the Xplods, I couldn't find em' when i looked for them, they sound better than most speakers. They stopped making them in California I think. What is your watts per speaker? Just take whatever wattage that is, and double it.

I am never going to tell someone their new purchase sucks, but I will tell you that they definitely aren't the best sounding subs on the market. There are a ton of brands out there that work better with small boxes and that don't require huge amounts of power.

They sound great, but make sure your box is deep enough for them.

ok.. on of my buddies has 2 xplods in his trunk.. they are just hard and high pitched bass.. I my self like soft low frequency puffing bass that you feel and want to listen even more.. to me hard and high pitched bass is anoying so i woudlnt recomend them..

As that goes i'm looking for a soft bass. I have 1 12" kicker L7 in my trunk and i love that thing because it just sounds so sweet

If you already have the box and cannot return it i'd just get 2 12" punch subs. I've had 2 10" punches and they sounded sweet (soft puffing bass) still my 12" kicker sounds better than both of them though but my kicker is a bit priceier . to fit the kicker i did need to move the rear seat a bit forward by playing/flipping the seat brackets

thats my sub.. 12" square.. in a custom home made box


and thats my amp.. kx 450.2 bridged

If i had to do it again i'd recomend getting a 10" L7 kicker sub.. not 12 so you woudnt have to mess with the seat.

As amp goes i'd get a mono kicker amp kx or zx.. (zx is the new line of kx..)

so zx750.1 for an amp..
http://www.woofersetc.com/index.cfm?...roduct_id=3788

Keep in mind when ordering subs you gotta look at the ohms too so.. the lower the ohms the louder it will be but each amp can only handle so many ohms so.. that kicker amp handles 2 ohms.

Also many subs are multiple voice coils so you gotta think of that too since many are rated ohms per coil..

i would go with an mtx sub. find one of their high powered subs. this will take up far less room than two. for a jeep 2 subs is overdoing it. it is a very small car with little room. having a single high end sub will sound just as good if not better. i have a 10" high powered sub and it sounds better than the 2 punch stage 2 subs he has in his jeep.

Even though I like Xplods, Kicker's beat them hands down. With that amp you should get 2 400-450 watt peak power subs, or 1 800-900 watt sub.

Check out the kicker site your self.. http://www.kicker.com/06/kicker_home.html

you're talking to me about the kicker zx750.1 amp? Well thats 750 RMS x 1 at 2 ohms. So 1 zx750.1 amp and 1 4ohm dual voice coil 10" L7 kicker sub should do the job.

4 ohm dual voice coil.. each coil is 4 ohms so if you wire them in parallel you will get exactly 2 ohms.

a 10" kicker sub is 600rms and 1200 watts peak power
a 12" kicker sub is 750rms and 1500 watts peak power so a 12" sub is better but you will have to move the rear seat if you want to put it like i have mine.. or maybe you can make a box that fires towards the seat..
my 12" sub in the box i made..



My amp bolted on to the tub right under the rear seat.

what do you all think of this potential set up?

Amp: http://www.crutchfield.com/S-WGlfHC7...0&I=113KAC8103

Sub (1): http://www.crutchfield.com/S-WGlfHC7...520&I=113W3011

Box: http://cgi.ebay.com/ws/eBayISAPI.dll...MEWA:IT&ih=001

Id like to go with the Alpine type R 12" sub, but I cant find a box that has enough mount depth for it...

Teal J one of my buddies has an Kenwood similar to this one.. ( his is 250 or something stereo so 500 bridged.. it sounds really good

The sub.. no idea since i've never heard it.. box.. seems kinda small for that sub.. the volume.. ~ .81cubic feet and when you place the speaker inside it would be even smaller which is way bellow the sub recomended volume. If you do want to use that box i'd seal the port so it sounds better since then the volume wont be that much off.

I would personally recomend getting a high powered 10" sub though and just making a long box like mine so the sub is beating sideways and not into the seat .

btw that sub link you posted is for a 4 ohm.. if you actually want to buy it along with that amp.. get a 2 ohm since the amp can support that. ( the 2 ohms make quite difference in power)


as wiring kit goes.. ebay it.. i found a 4 gauge kit for just under 30 bucks shipped to my house (it costs like 109 at best buy)

4ohm sub has more or less power than the same 2ohm sub?

OK.. the lower the ohms of the sub woofer the louder it will be with the same amount of power ur amp gives BUT every amplifier can only support such a low ohm rating. So that said you can only go so low. That amplifier you posted (the kenwood) has 500rms at 2 ohms. OK just to make it easier let say every speaker you test on there is just single coil.

so now you have the kenwood support 500rms at 2 ohms.
You plug in a 2 ohms speaker on there.. you will get 500 watts of blasting.
You plug in a 4 ohms speaker on there.. you will now only get 300 watts of blasting simply because the 4 ohms has more resistance in the coil so you need more power to move it or with the same power it will move less.
If you plug in an 8 ohms speaker on there you'll possibly get just 175 watts out of that.
On the other side if you put in an even lower ohm speaker a fuse will blow or safety will kick in or if nuthing is there ur amp will blow.
So let say you put on a 1ohm speaker and ur amps minimum is 2ohm. You will only turn it up to 100-150 watts and it will shut off every few seconds, or if protection isnt available on the amp it will simply heat up and fry.
