97 jeep grand cherokee, system wiring

I have a pioneer cd player with one set of rca jacks. i have it hooked up to a kenwood amp that has no possibilities of connecting a universal bass controller. all bass controllers i have come by requires connection of rca's to the headunit and the amp.

if i bought 2 of these 2-channel male to female rca y cable's like the ones in the link below....

https://www.bestbuy.com/site/Kicker+-+X-Series+3.3%27+2-Channel+Male-to-Female+RCA+Y-Cable/9925426.p?skuId=9925426&ci_src=14110944&ci_sku=9925426&ref=06&loc=01&id=1218195829912

could i connect the rcas from my amp to one end of one of the splitters and the other set to the universal bass controller? (below is a universal bass controller example.

im amateur at all this and im not sure if doing this with the rcas will mess up anything considering sound and performance.

thanks if your reading this and replying

and i have a 1997 jeep grand cherokee laredo. not sure if that applies

Your link is not allowed to work here.  I can only imagine that the following product is what you are trying to use.  This device connects in the RCA cable between the radio and the amp.

Part Number: LC-1 Category: Audio Interfacing Description: Remote Level Controller

Run a short set of rca's into the uni bass remote input and then your existing rca's into the output of remote into the amplifier input.

Thanks Chadillac, i never even thought of that.

hi, i have a 1997 jeep grand cahrokee laredo, and i have a Kenwood KAC-8104D Class D Mono Power Amp- rated 1000W, and CEA Rated: 300W (1.0% THD+N) (4Ohm/1Ch)
CEA Rated: 500W (1.0% THD+N) (2Ohm/1Ch)
and 2 Kenwood KFC-w2512 subwoofers rated at 4ohms 1000W and 300W RMS.

the manual for the amp: https://www.kenwoodusa.com/UserFiles/File/UnitedStates/Consumer/Manuals/kac8104d.pdf

the manual for the subs: https://www.kenwoodusa.com/UserFiles/File/UnitedStates/Consumer/Manuals/kac8104d.pdf

i have a few questions.
first off how should i wire these subwoofers? because on page 4 of the amp manual you can see that there are 2 channels even though its a mono amp. i was told by kenwood to hook them up like it is shown by the illustration on page 4, but i was told by a audio installer to wire them in a parallel as shown in the first picture in the link below,

https://www.the12volt.com/caraudio/woofer_configurations.asp?Q=2&I=41#results

and the last two sets of subs i got from kenwood have become partially blown, and ive needed to send them back and they sent me new ones. so im wondering how i should wire them, so they sound great and hit hard, and so i will not blow them, EVER AGAIN.

ALSO

i currently have 16 gauge wire hooked up from the sub to the box and from the box to the amp no less than 3 feet away. i was thinking that maybe this could be part of the problem and i was wondering if
the 12 gauge wires (in link below) would work for replacing all those wires i mentioned.

Your amp is a one channel amp, it just has 2 positive and 2 negative terminals.  They are connected together inside the amp.  There are 2 of each only for ease of connection. 

Okay thank you, any more information about the other things would be great

KAC-8104D Class D Mono Power Amp- rated 1000W,
CEA Rated: 300W (1.0% THD+N) (4Ohm/1Ch)
CEA Rated: 500W (1.0% THD+N) (2Ohm/1Ch)

so since its one channel, i should wire for 4 ohms? so the rms wattage is at most 300, because my subwoofers can only handle up to 300W RMS.

or does that number get divided by two because i have 2 subwoofers? so at 4ohms (just positive to positive and neg to neg like the manual says) i would be running 150W RMS?

and if thats the case should i just wire at 2 ohms (wired in a parallel), where 500W is split in half and each sub gets 250W RMS?

take a look at this diagram below, its wiring in a parallel, but since "[My] amp is a one channel amp, it just has 2 positive and 2 negative terminals. They are connected together inside the amp. There are 2 of each only for ease of connection." how should i wire them into the amp? should i just use one of those connections?

You can connect it as in that diagram, or you could connect one woofer to one set of terminals and the other woofer to the other set of terminals.  It makes no difference at all.  One to each set of terminals would fall under the "ease of connection" category. 

If you connect them as in your diagram, and get a different amp that will not run 2ohm mono, you will have to remove woofers from the box and rewire it.  If I build a box, there is one set of wires per voice coil coming out of the box.  If I ever have to change wiring configuration, I NEVER have to take a woofer out of a box.  If it were me, I would connect one woofer to one set and the other woofer to the other set.

I thought the main difference in the wiring was that wiring as shown in my diagram (wiring in a parallel) would produce a higher RMS wattage to each subwoofer.

im just trying to get the best performance out of my subwoofers and make sure i dont have a repeat of partially blowing them.

my subwoofers are new and arent installed into the box yet, so thats why im asking.

as far as the wires im using:

i currently have 16 gauge wire hooked up from the subs to the box and from the box to the amp no less than 3 feet away. i was thinking that maybe this could be part of the problem of why they have blown (not sufficient enough wires for amount of wattage transfered) and i was wondering if
the 12 gauge wires (in link below) would work for replacing all those wires i mentioned.

i was told i can hook them up pos and neg to the terminals on the amp pos and neg and it would be the same as wiring in a parallel. BUT
I thought the main difference in the wiring was that wiring as shown in my diagram (wiring in a parallel)

Should be fine.Use 2 equal lengths of 12g speaker wire going to each speaker

thank you! any suggestions for wiring them?

and 2 Kenwood KFC-w2512 subwoofers rated at 4ohms 1000W and 300W RMS rated at 4 ohms.

The Subwoofers are wired in a parallel, with 12 gauge monster subwoofer cables.
The Pro Installer took all my amp settings and maxed them out except the LPF frequency.

BOTTOM LINE IS THEY SOUNDED HORRIBLE.

I was told that the most important setting was the input sensitivity control (according to a tech over the phone from kenwood) which the pro had it set at max of .2V.

i have a pioneer head unit that has a 2V output.

What settings are most important in making sure my subwoofers do not blow?

And can anyone explain to me each of the settings that are listed on the amps' manual (the link is below) and tell me what they do, and if the if each setting is meant to be set by certain standards according to Volts and amps and what not, or if the settings rely on what sounds best by ear?

that really doesnt help me, but now i know what my LPF is used for.

mtcrssbig  where in NC are you? please step away from your jeep  turn everything down...then turn your LPF to around 120ish maybe a touch more depending on the type of music you listen to, then adjust the rest from there for loudness. If you play with the settings your head unit you can probly make yourself happy. your boost and gain can "blow" your subs
