    I got a $200.00 BestBuy gift card for christmas and decided to put a little bass in my 2004 silverado 1500 ext. cab. with the bose setup. I'm 30yrs old so I wasn't looking to get alot of really loud and deep bass, just something to add some depth and feel to my current factory stuff. I didn't want to loose too much space either. So....

    I bouth a pioneer gm-3300t amp and a RF p1s410 and built my own box. But I'm only getting really weak sound and very little bass out of the setup, in fact the 5" bose doors speakers hit harder than this sub/amp. So I'm wondering if I got a bad amp or sub, or if I'm just not putting enough power to the sub. specs on the items below

    Pioneer GM-3300t amp:
    60W RMS (continuous) @ 4 ohms
    75W RMS (continuous) @ 2 ohms
    150W RMS (continuous) @ 4 ohms, bridged

    RF p1s410 Sub:
    Impedance 4-ohms
    150w RMS
    300w Max

    I'm running 10ga wire to power the amp & 16ga to the speaker. I have verifed all connections several times each. the wiring is not the issue. I figure that even if I'm only actually putting out 100w rms that the sub woudl still do okay since RF & cructhfield recommend 50-150w for it. also I'm pretty sure i have about .76 cubic feet of air space in the box i built, witch is within the range specified by RF.

    I know both of the items are entry level cheapo's but i figured they would fit and work fine for what I'm wanting. Do you think I got a bad amp? Or do I need more power? What do you guys think?

    I should add that even when hooked up to my MP3 player using an RCA cable it still sounds really weak. My MP3 player sounds great when hooked up to my home stereo this way. is there a way to test and see what my amp is actually putting out?

    maybe it is the enclosure. i built a box for a friends dodge ram quad cab and i built it to spec and it still sounded horrible.

    i double checked it in my truck and it still sucked. so we made a bigger box for it and got a slightly better sound from it.

    Also I Would Check The Gains And Turn Up The Bass On It, If It Isn't Already.

    i agree on the enclosure,you should make it a little bigger. the specs that the companies give you for sealed boxes hardly produce any bass. building to specs is overrated lol

    thanks for the input guys. I figured out the problem. If you have a chevy pickup with the BOSE system You have to find and use the speaker wire going to the two subs under the console. I did this & I'm getting exactly what I wanted and expected. It took a lot of iternet research and phone calls to a few shops to figure this out, so I will outline the process incase anyone else has this issue.
    -----------------------

    installing an amp and sub into a chevy silverado ext cab with the BOSE system:

    first thing first: you already have two subs (6") and an amp in the truck; they are located under the center console. Unscrew all the screws holding the storage box in place and pull it out, then pull out the cup holder. You should see the factory amp under the storage box. The two subs are too hard to get to so don't worry about finding them, but incase you are wondering they are towards the front of the truck almost directly below the a/c controls. Before you take all this apart you should go buy a decent line output converter (LOC). I used the slc-4 ( http://www.scosche.com/products/sfID...productID/1388 ). hindsight being 20/20 I think something like the scosche LOC-80 ( http://www.scosche.com/products/sfID...productID/1387 ) would of worked just fine if not better. you can get either at Wal-Mart for under 20 bucks. I hooked up the slc-4 by connecting the 4 wires going to the two factory subs as left rear & right rear on the box and switched the LOC to line-in.

    The wires for the subs are found on the passenger side of the factory amp. they are:

    left sub is
    Lt Grn\Blk(-)
    DkBlu\Wht(+)

    Right sub is
    Dk Grn (+)
    Lt Blu\Blk(-)


    splice into all four wires and connect to the LOC following the manufacture instructions. Run your RCA cables to your new amp and you should be good to go. The rest is a typical install from here on out. It took two days worth of looking through forums and doing Google searches to figure this out... hopefully I have given enough details that it wont take you that much wasted time to get the job done.

    The key here is that you have to get your amp inputs from the factory sub wiring.. which is found on the passenger side of the factory amp.

    hope this saves someone some time and trouble along the way.
