How to run after market speakers with factory amp
801094
I simply connected the aftermarket speakers to the factory harness. Hope that helps.

A lot of mosfet head unit amps are cleaner than your factory car amp (depending mostly on how old your car/truck is) and you will want to bypass the factory amp. In some cases, factory amps are nice but most (toyota..) are junk.

They sound ok just being ran to the radio but to get max potential out of them put them on a small aftermarket amplifier. I used the infinity 475 high performance 4 channel

I located an aftermarket power supply from Radio Shack which works great. Just had to verify voltage/amps were the same as noted on the Boom Box.

Just use the in and out jacks on the back of the speakers. Out from the speaker connected to source in to additional speaker.

You would need the cleansweep,fosgate 360.3,audison bit control or audio control. Factory head units have preprogramed equalization to make cheap factory speakers sound good. The cleansweep or those other products flaten out the factory equalizition and give you a clean signal to amplifiy. I put a 7 band clarion eq after the cleansweep,then out to my three amps,can fine tune any frequency ,bass control,or fade anytime you want. Only down side is the master volume is controlled from the clarion eq ,not the head unit

If im not mistaken a aftermarket/stock radio pre-amp is 45x4 or 50x4 meaning your slightly better from amp than running from headunit. Depending on amp actual power may be less than advertised. it will work but dont expect them to be much louder than stock speakers. i have a 2500 watt 5 channel amp running 100 watts to each to these(and they could have more, but plenty loud with just 100watts) and the rest for subs.Side note when buying amp/ speakers you want the amp rms at least 80% of the speakers peak for best results.

You can run them from the factory head unit if that is what you are asking. Of course $250 of external amps would make them sound better.

Run the amps from the pre-amp outputs on your receiver. YOu should have at least two sets of pre-amp outs

As long as they fit in the factory location no you wouldn't. If you're car has a premium stereo from factory you might be fine. But generally running an amp is the best way to go to get maximum sound out of a speaker. Underpowered speakers are just as detrimental as over powering. I have my dash to the radio then 2 sets of these 2nd set replacing my 6x9s and a p1 10 all mated to a 600.5 rockford prime amp. If you like to go that route rockford makes adaptor plates for these to be down sized. Circular speakers produce sound better than any other shape. And having the speakers be dedicated to a type of sound helps as well. As long as they fit in the factory location no you wouldn't. If you're car has a premium stereo from factory you might be fine.

This is the method I chose to add a mono sub amp. It has a remote turn on wire for turning the amp on and off with the cars system. Cheaper would be to run the remote turn on from the fuse box from any source controlled buy the accessory switch position of your ignition. The audio would be run from the rear speakers using a line level converter. I do not like that option because I prefer not to alter the factory wiring, and I can remove the PAC adaptor easily without altering any factory wiring.It has been my experience that line level converters do not sound near as good as true pre amp level outputs. I have also experienced feedback using line level converters. This is the method I chose to add a mono sub amp. It has a remote turn on wire for turning the amp on and off with the cars system.

Negative, these speakers will run fine with any OEM head unit, and fit in factory enclosures and locations.

8awg power wire w/ in line 50 amp fuse from batt, 8awg ground wire at amp. All you need to do is splice your factory speaker wire from the hu to the included speaker level harness that snaps into the amp, then run wire to your speakers. I just snipped the speaker wire behind the hu, and ran two sets of wires. One ran from hu to harness at amp, other set ran back to the factory speaker wires and spliced in so I did not have to run wires to each speaker

Make sure you go through the "Speaker-Setup" routine as described in the manual. I believe the factory settings are geared towards a 5.1 setup. You need to change it to a 2-speaker setup.

As has already been said, your receiver is set up for 2 "sets" or pairs of front and rear speakers, so 2 pairs of these using existing speaker outs should be just fine, and better than stock for sure. I made a cooler speaker box with one pair to be run off my car's 320W RMS amp, and it sounds AWESOME!

You dont, but definitely sounds better with a clean 50 watt or high per channel amp. I have them in 2 cars one right off the head unit and the other off an alpine 4 X 50 watt amp.

I wouldn't. I would home run them all back to the amp/receiver. But there is a good discussion on parallel vs. serial wiring here including amp considerations for different types of wiring. http://www.avsforum.com/t/1109592/pro-and-cons-of-wiring-speakers-in-series
