Question about Audio Players & Recorders

Car audio i am installing a premier deck with front,rear and sub preouts.my amp is too powerful for my rear speakers so can i use the speaker wires off the deck to run them and then the preout for the amp to run the fronts? it is going in a truck where the fronts are 6.5's and tweets through crossovers and the rears are only 4's should i use the hi rear preout or the mid front preout for the amp running the fronts?

Yes you can use the speaker output in conjuction with the rca pre-outs...but depending on the wattage of the amp, there may be a big difference between the loudness of the front speakers over the rear speakers. If you have a 4 channel amp you can put the rear speakers on the amp also and lower the input gain for the rear speaker. Or if you have a 2 channel amp, you could use a passive crossover to filter out some of the bass to the rear speakers since they are smaller, this would help prevent over-driving them...as it is normally too much bass that distorts and blows a speaker. I'm not sure what you are asking about the hi-rear preouts vs the mid front pre-outs. If you decide to use the amp for the fronts you should be able to connect the amp from the front preouts of the deck. Hope this helps.

Is there a wiring diagram for the nikkai EAPA450 Amp


Hi, if you still need a photocopy of instructions email me mail@srands.co.uk

If you want instructions in brief this involves POWER CONNECTIONS, PHONO LEAD & SPEAKER CONNECTIONS:

POWER (At the same time when routing these wires, I would connect the PHONO LEADS from the car cd player to the amp, if your car cd player only has 1 preout (1red & 1 white) then you will need two phono splitters, a female to 2 males. Phono leads carry the unamplified sound from cd player to the amp):
~ Permanent 12V+ (Thick lead that is fused direct from battery all the way to the amp, wire must be 20a to 30a +, hence 1cm diameter wire, known as AWG8, Maplin sell cheaper kits then most)
~ Amp REMOTE (A thin insulated cable (5a is OK) from car cd player amp remote wire, this turns the amp on when the cd player is on, if your car doesn't have an amp remote wire, suggest nearest ignition supply or seperate switch that you turn on when you want to turn on the amp)
~ GrouND 12V- (Insulated lead (20a to 30a) to nearest part of unpainted car chassis such as interior panel screw hole, instead of an insulated cable all the way from the batery, this is common practise.

SPEAKER:
Each speaker has a - negative & + positive, these must connected correctly. The amp has 4 channel, 2 channel labeled as front, 2 channels labeled as rear. Using speaker wire, connect cable from amp to speakers. Note: Ensure the speakers being connected only receive sound from the amp (Not cd player as well, as would damage players or at the very least impair sound)
The amp has a feature called bridgeable this means a sub 8" or 10" sub can be powered by 'bridging' two channels. For example there are 2 ways to bridge power a Sub on the NIKKAI EAPA450:
i) Sub speaker wire positive + to channel RL and Sub speaker wire negative - to channel RR.
OR
ii) Sub speaker wire positive + to channel FL and Sub speaker wire negative - to channel FR.

Switches:
~ Bass boost, meant to be on for a channel if using sub, otherwise off.
~ X-over mode adjust hi/lo frequencies, only work if both x-over switches are on! Then adjust switch frequency knob, until it sounds right.
~ Gain (Volume knob) adjust volume knob up or down, until it sounds right!

NOTE:
You will need patience! many hand tools and parts such as: Wiring kit, fuse holder 20a/30a, Phono leads, speaker cable, Fork/ring connectors, wire strippers, wire cutters, set of screw drivers, also ueful to have zip ties to tdy excess cable and 'P' cable clips to tidy speaker wire to shelf, etc.

OK

Any more questions just email me mail@srands.co.uk

Need to know the wires to install a deck for 97


Red is power to from ignition to cd deck
Yellow is direct power from battery to cd deck to hold the memory.
Black is ground
Blue is only needed if you are hooking up an amplifier.
I always suggest buying a wire harness quick connect system for $5, then you won't have to cut origional car wiring. If by chance you are taking the original wire route, then go to installer.com to find which wires on the car are for what.

Have stock radio # F75F-19B131-AA its in a 1998 F250 need to know how and if i can hook up one Amp for the two door speakers, and if i can hook up an additional Amp for some subs. Ofcourse if radio can do...


You will need a line level converter for starters (takes speaker level signal and converts it to line level/RCA signal) you connect this to the speaker left/right wires and it has a RCA left right on other end to connect and run to your amps, (you need this box because factory radios don't have RCA outputs on them) At that point all you have to do next is run the power/gnd/rem for your amp and then speaker wires to your front/rear speaker and then sub (if using). You can use one of these converters for your front/back speakers so you will still have use of your front/back/left/right fading options. make sure you disconnect th factory plug/harness at each speaker since the amp will be powering them and you will run speaker wires to each speaker. If you only want one converter it will be on your front channel and your sub will be power by the front. (you will fade to front for more/less sub bass unless your amp has a separate volume/bass control). If you want your sub to fade with rear speakers you will need to install another converter off of the rear speakers. Found a site with some photos that may help you with your project.

Can I use front preouts for subwoofer?


First, you have to have a self-powered subwoofer (or two) with this reciver. That means the sub has its own amplifier. These are usually capable of accepting either Line Level (RCA) input or direct L and R amplifier channel speaker wires from your receiver from which it will react only to frequencies in its range. It doesn't actually use any if the power from your receiver's amp.

That is why you can extend your front speakers from the sub. Again, understand this - it is not playing any part in amplifying them. The amps in your receiver are just passing through it.

Setting your speaker 'Type' definition to Large will tell your receiver that they are capable of real bass (as opposed to small satellites) but won't necessarily steal anything from the subs. Set your LFE/Bass Out setting to Both if your front speakers are capable of handling real bass. Why would you want to deny them bass if they can handle it?

This part is confusing "If I can get the sub working on taking the lows out of the front speakers if I set them to large on the receiver then that is one thing less to send to the other sub on the LFE channel". The crossover feature allows you to define what bass goes to the sub. You would use the various points to smooth out the transition between your sub and the rest. Your quote of 47hz spec for something doesn't suggest your other speakers are great bass reproducers. One needs to see the +- db spec with less than x% distortion for that number make any sense.

Your receiver has two RCA Subwoofer Outputs but I'm sure they get the exact same level. If you're having trouble matching two different subs doesn't at least one of them have an adjustment for volume? Or maybe you could use physical positioning to adjust their comparative volume.

Need to know the right setting to apply for my subs


You need to match your amp's input voltage (the gain) to the output voltage supplied via your deck's preouts. Turn you radio up to normal listening level, and turn the amp's gain until you induce audible distortion then back it off slightly. Set the bass boost and crossovers to on and type (highpass for front/rear full range or lowpass for subs).
