I want a wiring color code for a PYRAMID COMBO 7 BAND EQ / 300 WATT AMP unit-I have seen this OLDSCHOOL THING8Dstill works,But the at the time This Models SPEAKER WIRES*OUTPUT PLUG*on the end of wires had been cut off-What do these 4 sets of matching 8 color coded wires go to? 1 white wire,1 white Has black stripe-1 yellow wire,1 yellow Has black stripe-1 dark blue wire,1 Has black stripe-1 brown wire,1 brown wire,Has black stripe-Can somebody who grew up with 1980s-90s Equipment help me with this-LOOKING FOR 1980's OLDER CAR STEREO(*-Cassette Auto-Reverse head units:D-*) GROUPS. Yeah.I know head units use CD/DVD with I-POD INPUT JACKS*BEST IN-DASH UNITS HAS SD CARD SLOTS with USB PORTS*, But these CD PLAYERS(video players too!) NOT AS RELIABLE(players get knocked out,Or disks get damaged-Cuz today's stuff IS MADE DELICATE:xnot designed to last years) Unlike the NOSTAGIA 1980's CASSETTE EQUIPMENT. I still got 30 year old home cassette players and cassettes STLL WORKING GOOD after all these years

Are there 2 sets of input wires? This unit being as old as it is, it may not accept input from a newer floating ground radio. If it does have 2 sets of speaker level inputs and you are going to use a newer high power radio, you need to follow these instructions carefully. Connect only the positive speaker wires of the radio to the positive input wires of the EQ. Do not connect the negative speaker wires of the radio to anything. Insulate the negative speaker wires of the radio so they do not touch anything. Ground the 2 negative input wires of the EQ. Once you get the input wires and power and ground to the EQ, you can turn it on and test the speaker output wires one channel at a time. Use the balance of your radio and the fader of the EQ to determine which channel that set of wires powers. Then move to the next set of wires.

Thanks,But This PYRAMID MODEL 705 300 WATT COMBO MODELhas only 2 CHANNEL INPUTS(4 WIRES,1+ left & 1 +right,The other 2 are -N Ground,And does have 2 HI-END RCA INPUT JACKS,Which is simple enough)...Whats confusing me is those COLOR CODED 8 OUTPUT WIRES TO SUB WOOFERS- I dont trust that Trial & Error wiring blind kind of work,Only reason because of the TIME LOSTcorrecting FRONT to REAR,Left to Right FADER HASSLES-Theres nothing wrong with a unit this old,I just need to know what color wire goes to what speakers? Some kind of a reply that looks like this-1 WHITE wire(+) and the WHITE /Blackstipe(-N) goes to LEFT REAR SPEAKER...
