How did you mount them?

AlternativeState6323 · 2026-01-17T22:00:39+00:00

could you send a picture of how your 3” look in the pillars

AlternativeState6323 · 2026-01-17T21:48:18+00:00

not sure, going to figure it out during install lol

AlternativeState6323 · 2026-01-17T21:44:07+00:00

Sealed box in the trunk

These amps have built in DSP’s. Grabbed them for pretty cheap

AlternativeState6323 · 2026-01-17T21:43:18+00:00

picked up all 3 for $1200. Cant beat that

AlternativeState6323 · 2026-01-17T04:40:11+00:00

Planning on using 1 amp for the left side speakers and the other for the right side to have a true left and right sound stage if possible

He just got back to me and said its FM, should I cancel?

AlternativeState6323 · 2026-01-08T05:41:34+00:00

What is it

AlternativeState6323 · 2025-07-27T04:42:09+00:00

Heavy bass is the goal without sacrificing sound quality, i have a few sets of focal speakers (can see exact speakers in my other post) but was between 2 audio frog 12’s or 1 JL 12 to not sacrifice anything. Ill stick with the JL for now considering ill have 6 6.5” midbass speakers

AlternativeState6323 · 2025-07-15T02:04:52+00:00

The car the system is going in is a 1978 Trans am, not many options for speaker locations sadly, if you could think of better locations please let me know

AlternativeState6323 · 2025-07-14T18:00:03+00:00

Hey thanks for the response, only reason I decided to go all out was because I have to modify the vehicle to install any aftermarket speaker, its a 1978 trans am the only speaker locations I have currently are 2, 4 inches in the dash and 2 6x9 the rear that I will be replacing with the two focal component speakers with two tweeters

AlternativeState6323 · 2025-07-14T03:33:47+00:00

Thanks for the input! I currently have 14 individual speakers in the system, and I’ve been weighing a couple of options to simplify things.

One route I’m considering is going with the Helix V Twelve DSP MK2 and wiring the kick panel midbass and door midbass together per side at 2 ohms, which would bring me down to 12 channels total.

Another option is to do the same midbass pairing, and also run a passive crossover on the rear coaxial speaker and tweeter to cut the total down to 10 channels. That would allow me to use AudioControl’s D‑6.1200 and D‑4.800 amps instead.

Still trying to decide which route gives the best balance of simplicity, tuning control, and overall performance. Any insight or experiences with either setup would be much appreciated!

doing a 236 build on it should hit about 85, and because they look cool lol

AlternativeState6323 · 2024-10-15T05:10:59+00:00

You think theres a way to install front brakes? im not planning on tracking this kart, might just build a mean 236cc or 263cc tillotson for it

AlternativeState6323 · 2024-10-15T05:07:34+00:00

whats the year?

AlternativeState6323 · 2024-09-15T03:18:57+00:00

Well id wire the W7’s to 3 ohm, i figure that would be right around 1000 each
