The speakers may have plugs that are compatible with sockets in the rear of the ampm if they are compatible it is a simple matter of inserting the pins and pushing them home.
It may be that the speakers just have bare wires and the amp has spring loaded wire retainers ...in that case you will acertain which of the speaker wires is negative and which is positive and , while pushing down the spring loaded clamp of the speaker wire retaining clamp, you should insert the appropriate wire in the
appropriate hole and release the catch
as a matter of interest what are the makes and models of amp and speakers?

make sure the power wire and the remote wire have voltage. at least 12 volts. make sure the ground wire is good and has a good solid ground. after that make sure the rca cables are getting signal from the radio. if you have a small speaker or tweeter you can touch the wires from the speaker to the rca cables and it should play music very quietly. meter the subs and make sure theyre ok and not shorted or bad. if all that checks out good.... the amp is probably bad. start with all the simple stuff and work youre way up. if the amp has good power and signal and good speakers then the only thing thats left is the amp. good luck
Yes you can modify RCA cables to make bare wire tails. If the unit has a sub o/p then you just connect up your sub bass unit to whatever the amp needs.
An RCA cable is 2 wire which is all you would normally need for sub bass speaker level signal. It may be a good idea to eventually upgrade the wire size if you want really good sub bass as lower frequencies draw more current and so require more copper.
Please let me know if this any help, thanks for using FixYa.
With a 1.5 Volt Dry Cell (AA Size), connect two pices of wire with the Cell. Momentarily touch the wires with speaker several times. It should produce click sound when wires are touched. If not then speakers are defective and need repair. Do not touch the wires for more than a second, touching the wires for a long time may damage the speakers.
3 things make sure all the speakers in the car have tape to avoid grounding the speakers
next make sure all wires in back of unit are taped
if all that is taped good its the amp over loading use a larger ground wire to fix this
hope this helped
If the voltage is dropping to 8v, it sounds like there is a problem with either the B+ line or the ground connection. You should also check the voltage across the battery terminals to see if the voltage is dropping at the source.
The amp may be going into protect mode. Disconnect all speaker wires from the amplifier's terminals. Also disconnect the RCA cables from the amp. Does it still go into protect?
Insert a 20 amp fuse in the B+ line and try to power it up. If the fuse blows with no speakers connected to it, the amp probably has a blown channel.
Over-current lights are often caused by speaker wiring or impedance problems. If you're trying to use the amplifier in bridged mode to both subs, that may be causing the problem; re-wire the speakers so that each sub is connected to one amplifier channel.
If you still get the over-current light, disconnect all speaker wiring from the amp and see if it still occurs. If it does, there's an internal problem with the amp. If it doesn't, then there's still a wiring problem with the subs. You may have a defective sub, or a speaker wire shorted against another wire or terminal.
Mono amps often have two sets of speaker outputs; this is just to simplify multi-speaker connections. The two positive and negative terminals are connected together internally, so they're effectively the same as one terminal. There's no difference between connecting both subs to the same positive and negative terminals, or using different terminals for each sub; electrically they'll all be connected together either way.
