Do i need an Amplifier?
 
i have this deck Sony Xplod CDX-GT250MP CD receiver at Crutchfield.com and i have some stock pioneer speakers in the dash and some sony red/silver sony xplods in the soundbar and i really wanted to get a sub woofer to put in the trunk i was thinking whatever is the best performance to price ratio but im not sure exactly which i wanted, i saw this Amazon.com: Infinity Basslink 200-Watt, Dual 10" Powered Subwoofer System (Black): Electronics and it looked pretty sick but idk, can i get some help lol?

Ehh. For that you could prob buy 1 10" sub ($50) a box ($50) and a decent amp. Total, $200-$250 :)

I'm gonna go with a bazooka bass tube with built in amp they make en marine grade and I looked last nite on amazon there reasonably priced through them. You can get a small amp to run your other speakers off of.

I have this player CDX-GT640UI | Xplōd™ CD Receiver | Sony | Sony Store USA and Infinity speakers in sound bar and front dash. Wouldn't even think of adding amp or sub.

To small/enclosed of an area for needing absurd amounts of power, IMO. Besides, with soundbar almost directly above my head and front dash speakers pointing directly outwards at me, the sound is right there.

I would get a bazooka tube (NON amplified), and get a 4 channel amp to run interior speakers AND the bazooka.

Also would consider if you are gonna be driving top up or down? Granted the sound quality may be acceptable in the small space as Cork suggested with the top up. However, any system can benefit from the addition of even a modest amplifier. The limitation with jeeps is the amount of road noise that your setup is competing with. So the addition of an amplifier would certainly help you to increase the volume while still maintaining better sound quality. That, versus running off the head unit and running into distortion issues as you increase volume.

Regarding head units, power output is often in the range of 15-25 watts RMS (don't fall for the 4x50 watt Peak Power marketing) RMS is steady/continuous power. As such, most head units are underpowered to efficiently drive aftermarket speakers which will typically demand 35-100 watts RMS (referencing the 4.5 - 6.5 inch speakers most jeepers use in dash and soundbar).

Turtle's suggestion is solid, he may have meant a 5-channel amp (4 mains + 1 sub output as well) and your sub.

good luck with your jeep jams!

No, I meant 4 channel as the only thing he'll lose by only using front to channels is fader ability. Using a 4 channel as opposed to a 5 channel he will save some money and still have good quality sound. My buddy owns a car audio shop in Pensacola and he does this set up for A LOT of his customers as its a great way to get a complete system and save some money. Im running a 4 channel right now in my jeep and sounds great.

so what you guys are saying is i need to get an amplifier and plug that into the amp/sub out on the back of the head unit, and then i need to just plug the sub into the amp and leave the rest of the speakers alone and how they were right? sorry idk how to even set up an amp :confused:

slyr114 07-09-2011 06:59 PM

couldnt i just get something like this or the bazooka's that have a built in amp?? that way i could just wire those to the battery or however you would right?? and then into the headunit and be done? Amazon.com: Infinity Basslink 200-Watt, Dual 10" Powered Subwoofer System (Black): Electronics

Get a quality alpine head unit and no worries. I drive top down 80mph on nj highways with my headunit powering ma audio components up front and 5.25 in back and never have any issues. Or if your dead set I have a ma audio amp 800x4 I can give ya a deal on. My experience with Sony is the name says it all explode

I would say look for some pioneers for ur subs, 10" ($50) 12"($75). thats what i got mine for, If u have any questions about sound systems, speakers, radios, anything that makes music, hit me up. Im a nerd for that stuff. Thats how i spend my free time, hooking that stuff up and researching.
