    The remote bass gain on the driver seat broke, and I need another switch, what should I do?

  • Michael21 Nov 19, 2007

    The switch under the driver seat, near the brake and gas pedal broke as I was trying to turn more bass up. I went back to Future Shop to see if they can fix it, they told me they can't help me, and they have no switch replacement. They then lead me to this site and buy a new bass gain switch, I tried calling your number on this site for some help but it doesn't work, and says the number does not exist. 1-800-225-5689, if this is not the number please refer me to the right number so I can contact someone to help me. Thank you, sincerely, Michael

Your amp remote turn on lead supplies a tiny amount of voltage to your amp letting it know to turn on. if you never hooked this wire up from your receiver to your amp, of course it wont turn on.

SOURCE: Red LED "Protection Light is on" What is the problem

The red light means the amp is in protection mode. A few things can cause protection mode..... First disconnect the subs completely from the amp, and turn it on, if it powers up you have blown subs. Also try checking the main power wire at the battery...sometimes the current your meter is seeing is backfeeding from the remote wire, so your main power line could be blown at the fuse under the hood. hope this helps

SOURCE: Hooking up system using HI-INPUT amp wires.

This may sound dumb, but are there any other inputs left on the amp? Most amps that i have worked with have a special set of inputs for high input. (by high input you mean speaker level right?) If those exist the obvious answer is to use those. They should be labeled, so just hook them up according to them. You may need a special adapter from the amp manufacturer. If you dont have any high level inputs or any not broken inputs left you have two options. You can either A: junk the amp or B: open it up and solder new connectors back on. (it sounds harder than it really is. There are four large pieces of metal to solder onto the board for a set of inputs)

Crunch 2000.4 car amp, need help tuneing


re-check the speaker connections are correct and use a matching ohm test speaker on the other connections for a sound check. Sounds like hi frequency output into the sub amp. Sub-woofers are a mono signal!!

Looking for manual for pioneer sw200 powered subwoofer


Most subwoofer have a left and right phono/RCA sockets. The amp should have a sub out phono/RCA plug. The sub should have come with a phono/RCA lead that will connect these - one plug to two plugs.
Apart from the mains plug that's all there is really. You may have to switch the sub socket on the amp on.

Or you can get one of the cables from places like below:

Sub hook up to Receiver


If the Pioneer has only one sub output connect it via a single RCA to the mono one. If it has two outputs (L&R) connect it to the L&R on the sub via a dual lead.
The other connections on the sub are for those amps without a dedicated sub output.
The manual for the sun can be seen online.

How can i test my rca output jacks with a test light? pioneer deh p3100ub. hooked up spkr, nothing. tried one rca plug to white(lt) and then red(rt). Unit has 4 rca jacks, 2 for subwfr and 2 for front...


:) the rca jacks have to be connected to an amplifier,, their signal is too lay to even light a bulb.. you have to connect it to a car amplifier and then from the amplifier to the speakers..

Just so you'd know,, once your deck plays and you hear music on your speakers through your normal speaker wires,, RCA jacks work..

Ok you have 4 jacks,, 2 subs and 2 front.. These should connect to a preamp,, which takes 4 inputs and allows you to equalize or adjust how the music should sound,, now from the pre-amp,, it runs to an amplifier,, thats powers the subs and another that powers the speakers.. Some amps have 4 inputs so you can use one amp for your subs mids and heights..

for example a basic music system is

1 cd player
1 pre amp
1 amplifier (4 inputs, 4 channel out)

you bridge 1+2 and connect this to 1 12" double coil sub woofer

the next 2 connect to 2 mid speakers example "rockford or ev 5 / 8 " and 2 tweeters for heights..

Thats a kicking tricked out basic car audio system,,,

Hope that helps you understand how it works..

SUBS WONT TRUN ON


Hello fresttadefjm,

There are no subwoofer settings on the Pioneer DEH-2800MP.

You need to check the external power amplifier and the connections from the Pioneer and from the sub(s). If everything is plugged in and wired correctly, check the amp fuses, both on-board and the main power fuse (located in the amp positive lead usually near the vehicle battery).

Hope this helps.

Pioneer 800w mono issue


It can be many things it possible the amp cannot handle the 4 ohm load and simply goes into power protection mode. Also make sure your using the correct gage wire to run power from your battery to the amp to thin and it wont have enough power to perform.

Sub woofers and amp


first of all is the amp a four way amp? if so then you need to know what the watts of the subs are (you dont want to melt them) wire + and - of channels 1 and 2 to one sub and + and - of channel 3 and 4 to second sub, nice thick lead from battery positive (fused) to positive terminal on amp thick lead from a good earth point to negative terminal on amp run a set of rca leads down the opposte side to the positive wire to prevent interference, run thin wire from remote wire of radio to the remote terminal of amp, rca's are plugged in at stereo and at the am. may need a RCA splitter to be able to power all four channels

Good luck Davelee

No sound


hi there
on your CD deck or what ever unit you plugged the RCA wires to needs to be set on subs the radio needs to be set to put sound to your amp.....on your CD player if you press the F/function button a few times it will scroll to SW which is for the subs set this to the on position or if your CD player has a button with SW press it and turn on this feature......if this has been done......check the fuse or fuses on the amp.......if you have done all of the above check the back of the CD unit to make sure you are plugged into sub-woofer RCA or R (rear) RCA ..........sometimes people accidentally put the RCA wires into the aux input RCA,,,,,, double check this.........
hope this helps
