Quality sound with replacement speakers


Recommended Posts

Posted

  I have an 18 LT 1500 and Im planning to add a sub.  I also want to upgrade the factory speakers but they will only be powered by the factory deck.   Would anyone recommend spending money on new speakers or is there no benefit if they arent powered by an amp?  I was hoping to keep it simple and run 1 amp for a sub. Thank you

I did almost exactly as you described on my 2017 LT double cab. I added a sub that is powered by an added amp but gets its signal from a line out converter tapped in to the rear speaker signal. I also replaced the front door and dash speakers. I plan to do the back doors but it’s low on my list.

My thoughts:

1. The sub is absolutely worth it and really adds to the sound in the cab.

2. The new door speakers, even powered from the factory system, sound much better than the OEM speakers.

3. The aftermarket dash speakers sound exactly the same as the OEM speakers. I’d skip those if I were you.

That helps. I wonder if the dash speakers need to be a little bigger, different tweeter or something.  If the doors sounded better, one would think the dash should as well.  Hmmmm..  Thanks for your help.  Did you build a box or buy one the prebuilt subs with the box that fits under the seat?

If you run an Amp for a sub, you've done the hard part (getting power, signal, and mounting). You might as well get a 4.1 or 6.1 Amp and power the speakers too.
In my progression, I went from door speaker replacement, to dash speaker replacement with 3", to adding aftermarket Amp for doors and sub, then adding a second Amp for dash, then getting an aftermarket 8" Sub. Each step was an easily notable improvment.
Personal recommendation: use a NavTV processor over a LOC; and don't skimp on the dash speakers or channel. The factory head unit sends tons of midrange to the dash and most of the environmental sounds (phone, chime, etc.).

Although I can see myself falling into the trap of more and more audio stuff,  Im trying to do this as easy as possible. I just want to do 1 sub amp if possible.  If everyone think it will sound like mud, I may go ahead with another amp but only if I have to.   Is everyone running power up one side and RCA's up the other?  Anyone built a bandpass box that fits?  Thanks for your help. :thumbs:

aftermarket speaker would be better that the paper cone factory speakers. depends on what you listen to. kicker makes a good speaker if you like loud music, more sound quality look for a "silk dome" tweeter by kenwood/alpine. i been out of the aftermarket game for a while, a simple upgrade would be and sub and coaxial speaker swap. the factory radio is not strong enough to power component speakers.

 

for running wires, yes you can run subwoofer wiring "class D" amp on the same side, if you plan to amplify the door speakers then you need to run power and speaker/RCA wires on separate sides.

I built my own. It was the first time I ever built a box but I wanted a sub enclosure and storage on the other side. There exists under seat storage and boxes for one or two subs but nothing that combines the two. Choices for the double cab are particularly limited.

I seen the thread and I really liked the work.  I may have to borrow your idea if you dont mind. What sub and amp did you go with?

Thanks!  The carpet on the box didn't turn out great and is something to work on for the next one.  I am still happy with the result and I love the sound.  As was mentioned earlier in the thread, I ran the power down one side of the truck (the driver's side in my case) and the signal cables went to the passenger side.  I went with a Kicker 12CX300.1 600 Watt Mono Class D Amplifier.  The sub is a Rockford-Fosgate P3SD4-10 10 inch.  I have done audio work in every vehicle I have ever owned and I have always had good experience with RF subwoofers.

 

Good luck with your project and let me know if you need more info.

    • You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode. 
    • "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...
    • // Thank you, also for your  response. More information is always good. This 2013 GMC is most likely my 'forever truck"-I'm 77 and retired...and truck only has 42K on it-very clean-so I try to keep it that way.  Tks again for your  response- glenn
    • I started my install this weekend. Everything was pretty straight forward but I ran into one issue with running power through the firewall. The nipple grommet on my High Country already has a small harness running through it - has anyone else ran into this issue? And on the engine bay side, does the wire basically just penetrate the factory wiring boot? I did this on my '22 Trail Boss and it seems much easier but thats been a few years. My other thought would be possibly drilling a new hole adding a rubber grommet just to the lower left of the factory hole. Thoughts?   Has anyone used a T-harness off the Bose amp and obtained power from there? It seems a little odd that such a small amp needs 3 power leads
    • ///// Ok--Thanks for that info--I could not find yesterday when I looked for the specs on that NAPA filter what I wanted. Their website is not very user friendly. I buy all teh filters for  our three vehicles once or twice a year. Have always run NAPA Gold on everything I own....I buy it thru my Son's account for his business-which he has a Heavy Equipment repair shop-one reason he uses NAPA so much-they have such a full line of coverage for just about anything/anywhere- He gets s  good discount because of volume bought. Anyway-Thank you -Sir for your response.   glenn
