Answer 1

The Line Level Converter or High to Low converter, is correct, but they make different types that do different things. I'd suggest looking for one that has adjustments. That way you can adjust the voltage signal input to the amp. This will allow you to gain a volume control also. Which in turn, will make the sub alittle louder. Some of these converters also have a remote turn on built into them. This will allow you to connect it to the remote turn on to the amp, so you will not have to run a seperate wire from the back of the factory head unit.

As for the amp. Make sure you run the proper size wires, and use the appropriate size fuses to protect your investment. Soldering loose wires together and heat shrinking the exposed wires that you soldered together will help with any future problems. Securely fastening and double checking everything is always a plus, especially when dealing with electronics and electricity.

Also, on another note, do you know the ohm load the amp can handle when bridged mono? And what ohms are the subs? Is the amp 2 channel or 4? Depending what ohms the subs are and how many channels the amp has, is a big factor on how you wire them, and if the amp can handle the load. Cause if it can't, it will prematurely overheat and clip.

I will assume the subs are 4 ohms like most subs are, and the amp is a 2 channel amp. Take a single wire and connect one end of the wire to the positive of one speaker. Take the opposite end and connect it to the negative of the opposite speaker. You will then have a positive terminal open on one speaker and a negative terminal open on the other speaker. Take two more single strands of wire, and run the positive and the negative to the mono side of the amp. What you just did, is ran the subs into "Series". You took two 4 ohm subs and bridged them up to "8 ohms". Then you ran these subs to the amp in mono. The rule is when you bridge to an amp, the amp will always see half the ohm load. So the amp will now see a 4 ohm load, and will be able to run "both" the subs, safely.

Hope this helps.
Good Luck!

Answer 2

If your amp has speaker level inputs, you can run branch off your speaker wires directly into your amp.

If it doesn't have speaker level inputs, you can buy a Scosche converter from Wal-mart for around $15.

You might even check out Scosche.com. Sometimes they have connectors available that split your speaker outputs for you without having to splice your wires.

Whichever route you choose, good luck.

Answer 3

Buy an amp that has "line level inputs" or "high impedance" inputs. If these are right in the amp, you don't need a "line level converter".

Pioneer, for example, has line level in for all of their amps, in addition to the RCA plugs.

Answer 4

Try a company called Crutchfield at crutchfield.com. They have a kit for practically every vehicle. It will allow you to wire up new speakers and amp if needed, to existing radio.

Answer 5

hey im not sure if you can have subwoofers and an amp with a factory radio i think itd be shitty sound. About the mps player with the factory radio you CAN buy (if you have a tape player) buy a tape with an aux cable on it and you can plug that into your mps player and play it on your radio. you can buy it at walmart

Answer 6

its called a line out converter. you tie it into your rear speaker wiring and it converts it to a RCA jack. you can get one at RadioShack for about 15 - 20 bucks

Answer 7

get some wire and wire caps/nuts and electric tape
