Can I hook up two subs and two component speakers to one amp effectively?

Question

Details—I drive a 2004 f-150 (STX edition), 2x 12” digital audio subs, 2x stock door speaker (I might upgrade soon) , Lightning audio B2.300.4 (I know this is probably c**p but it was free).

My friend gave me two 12’’ digital audio subs and a 300W class b amp. I really don’t have much idea of how to set this up but I’ve watched some you tube videos and done a bit of reading so I am learning.

Anyways, is there any way to connect my two door speakers + two subs to this amp and have it sound good? Also, what are ALL of the supplies that I am going to need in order to accomplish this job (not including tools)?

Answer 1

The simple answer is NO. That amp is a a 4x50, so your friend had each side bridged to put out 150 watts into each sub. So if you tried to hook the amp up to your door speakers also, then you would have each sub at 50 watts which is way too low.

You have 3 options. You can run your new door speakers (NOT THE FACTORY SPEAKERS) off of this amp and get another amp to run your subs. Or you can use the same set up your friend was using and power the 12's with that amp then get another amp to run your new door speakers when you get them. Or you can leave the door speakers as they are and again, use the same set up as your friend was using on the subs.

That amp is a 4 channel amp and it is 4 by 50 watts into 4 ohms. When you bridge each side, you get 2 channels at 150 watts into 4 ohms.

As for the brands, Lightning Audio is the low end brand of Rockford Fosgate, so it should be fine. But I have never heard of Digital Audio Subwoofers and I could not find the name on Yahoo or Ebay so I could try and find out what kind of power handling your subs had.

As for supplies, if your friend did not give you any wiring, then you will need a wiring kit. If you choose to use the amp on your doors, then get a 4 channel 200 watt kit, and if you want to power the subs then get a 2 channel 300 watt kitt.

My best advice to you is to go to your local stereo shop and ask them what you should do. They don't charge you anything to ask questions! Good luck.

No, that amp does not have the features needed to hook up woofers and door speakers. That amp is too small for just the woofers alone. You can run the 12"s off it but it is too small. If you do use it hook them up briged, one woofer on the front channels, one on the rear. I posted a link to the manual below. That amp would be best for running four door speakers. You are going to need a wiring kit, a 8 gauge kit will work for that amp but I suggest you get a 5 or larger in case you decide to get a larger amp in the future. Walmart sells a Scosche 5 gauge  amp wiring kit that will work excellent and only costs about $32. Its called the Scosche "Platinum" kit. The kits include everything you need, RCAs, power wire, speaker wire, terminals ect.

Answer 3

if they are standared door speakers they are prob about 50w so conecting them to a 300w amp whould just fry them.

what wattage are the subs?

you should try and get w for w so if its a 300w sub get a 300w amp so two whould need 600w amp and so on.

i whould recoment a starter kit.

i just got one for my G/F car.

it was a fusion sub starter kit,you get 600w amp 300w sub, two 150w 6x9's all cables and conections for wiring it to your battery, and to the speakers.

it cost £150

also what connections are on your headunit as you will need an rca output to run the amp unless you get one with hi level in which connects directly to a stock speaker in your car and then to the amp. (amps with high level in are rarer+ more expensive)
