There ya go....
I would try the Jensen....it's not going to rattle the store windows as you drive by but as an addition to a deck powered system it should do the trick....you will still need to set up the amp properly to get the most out of it, any questions just ask.
Have fun with the new toys....

I am ahead of you BigRedGuy,
Installed it on the weekend and it works !! I am quite impressed by the quality and the extra clean bass is music to my ears - so to speak lol.
Yes, tuning is my next concern. I have been doing some research online and it is starting to get more confusing lol.
My HU - JVC KWNT3HD - had a single subwoofer RCA so I used it and attached a Y adapter to plug into the jensen. The confusing bit now is the LPF settings - on the HU and the AMP itself.
What I think I learned - let me know if I am wrong - is that I should use the LPF settings on the HU - maybe 110hz or so , and turn the LPF setting on the amp all the way up. I think that will get me started.
Is there a thread that provides a step by step procedure on the forum somewhere for the amp tuning process ? Should I post questions here or in the Install or Technical forums ?
The new toys are fun.
thanks

Pick one or the other LPF....using both together causes phasing issues you really don't need to get into in a simple system (no offense intended).
I would start with the deck....you can fiddle with it while you sit in your listening position and will hear the changes you make as you modify the setting. I would suggest a starting point of 80hz.....you need to set your amp gain first and that is fairly straightforward. This is best done with a buddy and a CD of something you know well and would be listening to on a regular basis.
Shut off all bass EQ circuits in the deck...bass boost, loudness etc. and anything in the way of built in EQ for different music types ie. "Rock", "Jazz" "Pop" ...that sort of thing should be set to "Flat" "Normal" or "Natural"...whatever Jensen calls it. Unplug the RCA for the sub, if the deck will let you Xover all the sub-bass out of the speaker connections do so and find the maximum volume level the deck will do without any distortion in the mids and highs. Don't worry how it sounds, its just distortion we are worried about right now. Turn it down and re-connect the RCA. Set the gain control to minimum on the amp by turning it to the highest indicated voltage around the dial. Shut the Xover on the amp off and crank the deck back up to the previously noted volume level. You will probably find the bass is a little low now...you need your buddy to get in at the amp with a screwdriver and slowly raise the gain on the amp until you hear the sub distorting. You will know it when you hear it....you may hear a mechanical clanking sound or other new noise that wasn't there before you crossed a certain level on the dial. Turn that dial back down a step or 2 until that noise stops and you have found your starting point.
Leave it like that for a week or 2....listen to a variety of music and you should hear the difference between an old school rock song and something recorded with a much louder bass section....you have to set your levels to a happy medium and you can fiddle with the controls in the deck to "tweak" the sound for different types on the fly. The less boost and EQ you can use the better.....the amp will only put out a given amount of power and any controls you use to try and increase the bass will generally only drive the amp into distortion which will kill your sub faster than anything else.
The only real advantage to using the Xover on the amp is you won't lose your setting if the battery gets disconnected for some reason....
